You will find the best ATX v3.x & PCIe 5.x Ready PSU Picks 2025 in this article. PSUs compatible with the most recent ATX v3.x specs are way more expensive than the ones meeting the requirements of the previous ATX specs. You will probably wonder whether you should invest in them or buy an older-generation PSU and save money. Although none of today’s graphics cards has high enough power spikes to justify the demanding ATX v3.x requirements for power excursions, as it calls them, no one knows what the future GPUs will bring. You can read more on the ATX v3.0 specification in this article. We also have an English section on our Discord server if you have any questions.

The newer ATX v3.1 and PCIe 5.1 standards are already in effect. Since the significant difference between ATX v3.0 and 3.1 is mainly in the connector, from 12VHPWR to 12V-2×6, with the high-power cables remaining the same, I expect most ATX v3.0 PSUs to get slight updates for ATX v3.1 compatibility. A downside of the ATX v3.1 spec is that it allows for a lower hold-up time, from 17ms (ATX v3.0) to 12 ms.

An article that contains everything you need to know:

Will my ATX v3.0 PSU or my GPU be compatible with 12V-2×6? Do I need a new cable/PSU/GPU? Everything you need to know!

Another interesting article if you are wondering whether you should get an ATX v3.0 or a v3.1 PSU:

Should I get an ATX v3.1 PSU, or will an ATX v3.0 be fine? Everything you need to know!

  1. After seeing reviews of the Msi Ai1000P, I bought the 1300-watt version because the smaller one was not available, but now I noticed that this one is ‘inferior’.
    It hasn’t arrived yet, so I’m wondering whether to keep it or return and choose something else up to ~250€ for 7800x3d/4090.

    1. If it was at the same power level as the 1000W, it would be the same performance. The higher the wattage the more the stress for the platform, so performance goes down. I would keep it, because it is good to have plenty of Wattage room available.

          1. No, i meant you personal opinion on that psu exactly. You always talked and gave your personal opinion about only 1000W version in this page but you said that you didn’t completely sure about performance of 1300W for those askeed your thoughts. So, i just wonder if you have any new and definitive personal opinion for 1300W version.

  2. Hi!

    Which one seems like a better option, is it worth to pay a little more for seasonic?

    Be Quiet Pure Power 12 M – 154 EUR
    MSI MPG A1000G – 157 EUR
    Deepcool PX1000G – 158 EUR
    Seasonic VERTEX GX-1000 – 171 EUR

    Thank you in advance!

  3. Hello and happy holidays everyone. A question, which is the most reliable and best 1000W power supply at the moment now? and so that the wires do not melt when the video card is loaded:)

    1. Or for my ryzen 9 7950x / rtx 4080 (or 7900 xtx) with possible gpu upgrade in the future ( was looking at a 1200w psu), should I just get the corsair hx1500i atx 3.0? Overkill capacity but it’s $10 more expensive than the FSP Hydro PTM Pro or X Pro 1200w i was looking at. My computer will also run 24/7, I guess the Corsair will not be as efficient in lower loads?

      What do you think?

  4. Hey there!

    First of all thank you for replying to everyone. Amazing dedication and I really appreciate that.

    I am building a PC with a ryzen 9 7950x and a 7900 xtx / 4080 but i plan on upgrading the gpu in the future. Therefore I was looking at a 1200W PSU to make sure it’s futureproof.

    I am also looking for a silent enough PSU. My budget is $300 USD max. I saw the winner would be the NZXT 1200w but I’ve noticed that the NZXT PSU is pretty loud. I was also thinking of the FSP Hydro PTM X Pro 1200w(you don’t have that reviewed yet), but it doesn’t have UVP protection and that kinda worries me. Maybe it doesn’t need one? I don’t know that much things about PSUs

    What would you recommend? Would appreciate if you could make a small list of a few GPUs in case I don’t have them availble in my country.

    Thank you so much!

    1. 1200w are more than enough for futureproofing. U can check our best psu article or the psu tier list. NZXT is a decent choice. U can still consider rmx shift or rmx.

      1. I specified that the NZXT is loud. Plus it has multiple reports of coil whine.

        The shift is not compatible with my PC case.

        Aren’t the ones I specified better than a rmx? Is the UVP protection even necessary? Would appreciate a response from crmaris too, thank you.

  5. Hey, just bought an RTX Strix 4090 OC and rocking a 12700K chip. Since its Black Friday on Amazon.de, I want to buy a new PSU. Changing my Rog Strix 1000W Gold for a new ATX 3.0 1000 W PSU.
    I have the Corsair 5000D case and right now the Shift is 160 € and Aura Gold 1000 W is 220 €. What unit is better and what do you recommend ?

  6. But in the test chart for 200% transient load 10 kHz these power supplies are listed and perform quite well? In that case, they theoretically meet these requirements?

  7. Do I understand correctly that the Cooler Master MWE v2 gold in the 750/850 version, despite not being ATX 3.0 performs well in load ATX 3.0 test scenario for 200%? No need to replace it for ATX 3.0 PSU?

  8. Thanks for the PSU reviews. I am in the market for a 1000w ATX 3.0 PSU. What is the difference between the Seasonic Vertex GX 1000w ATX 3.0 and the new-ish Focus GX 1000w ATX 3.0 PSUs? I’m struggling to find the difference aside from the size (160mm vs 140mm length). Thnaks!

    1. I haven’t tested the new Focus, so I cannot share any insights. I suspect a different platform but I cannot be 100% sure till I review the new Focus GX.

  9. I went ahead with your suggestion of the Hydro Ti Pro 1000, sadly my unit has alot of coilwhine so it’s going back.

  10. Hello, first of all, thank you for the work and so much information. Secondly, a question, I bought a Deepcool PX1200G, and now for an offer I could buy the FSP Hydro PTM X at the same price (€204). Thank you very much again and greetings from Spain, if you plan to come here you will be welcome in Granada 🙂

      1. Sorry, I had problems with the website or my connection and I sent the message without the question! Being at the same price and being able to change the psu, would you change the PG1200X that I already have for the FSP HYDRO PTM X PRO ATX 3.0? If you think the FSP unit is better than the Deepcool one,I will change it.

        Thanks for the reply! Good food and beer are waiting for you in the most beautiful place from Andalusia, just mail me if you think about visit Granada again 🙂

  11. Hi crmaris, u do great job at these psu reviews.

    I currently use corrsair RM750x with i912900K (OC to 5300mHz) and strix4090.I get a lot of coilwhine from PSU and GPU on load.
    sytem work ok, but it may not look to good for my psu and other components in future.

    have u ever test Asus ROG Thor 1200W Platinum II (ROG-THOR-1200P2) ?
    is it good as they say it is?

      1. Thanks for reply.

        Ok, which are the best at this price range (400 – 500 Euro.) I’m looking for the best quality (No Coilwhine)

        best regards from slovenia

  12. @crmaris
    If you had to choose between
    1. Corsair RM1200x shift for 209$ (side connectors are not an issue)
    2. BeQuiet Straight Power 12 (1200w) for 249$

    Which one would you pick ?

  13. @crmaris, if you had to recommend one single ATX 3.0 power supply (1000W – 1200W) today, what would it be? I just bought all of the parts for my new build (13700k/4090FE) except the PSU because I’m torn on which would be best for quality, native 12VHPWR connections, noise, etc. There are many decent 3.0 PSUs now. And, it’s possible the 4090FE I got may have the new shortened sense pins, if I that matters (I read some of the newer batches have them).

    1. I’m torn between:

      NZXT C1200
      ASUS ROG Strix 1000W Gold Aura Edition
      FSP Group HPT2-1200M
      MSI MEG Ai1300P
      Seasonic VERTEX GX-1200

      Each of these have native 12VHPWR.

  14. Hi there. Thanks again for what you do. I bought the SuperFlower leadex vii gold thanks to your reviews and am very happy. I am wondering when the leadex vii plat reviews will be out.

  15. Hello!
    First, I want to extend my gratitude for your great site and work on PSUs and ATX 3.0 information. Few questions:

    1. Your original Corsair HX1500i review does NOT include ATX 3.0 power excursions however you include the HX1500i along with its ATX 3.0 power excursions in the ATX 3.0 recommended list. Was that because the HX1500i you reviewed was the 2022 version? And the excursion of the HX1500i you tested was the 2023 version?

    2. Is the HX1500i 2022 version meet the ATX 3.0 power excursion spec?

    3. Are the 2022 and 2023 versions the same?

    3. If I have the 2022 HX1500i, is it worth it to upgrade to the 2023 model?

    Thank you!

    1. The HX1500i I reviewed back in the day was the old model, ATX v3.0 wasn’t a thing yet.
      But I also have data for the new HX1500i, thanks to Cybenetics. I just need to find the time to review it at some point.
      If you have the non-ATX v3.0 model, no it doesn’t worth upgrading to the ATX v3.0 one. Just get the 12VHPWR cable, which uses 2x 8pins, and you are good to go.

  16. Best regards.
    I would strongly appreciate the advice and time to help with reply. I’m fighting the coil whine battle and main source of the wine seems to be the psu, isolated and tested (it’s very acceptable on the gpu side).
    It triggeres with high gpu usage only and while the gpu power load is over 350W or 400+. I’m always using the selected sampling from gaming to test where I know the exact behavour.
    The cpu is 5800x3d and gpu is zotac 4090 (450W card). I’ve tried very much to trace stuff and I don’t want to bother with too much details.
    The PSU I’m running is rm1000x.
    Tried hx850i, 3 more. All PSUs have a PSU whine with high gpu usage and power load and I’m simply stuck. The hx850i helped a bit, platinum1200 from Seasonic was bit better then rm1000x but not good enough (whine wise) and the fans are much more noisy compared to Corsair.
    The older rm1000x that I’m having in the pc is the worst and to put things simple, while the psu is “cold” the whine is bad and then after some load is put onto the PSU by the gpu (about 10 to 15 minutes) it gets a bit better and less anoying, same sampling area, same conditions all the time.

    My question is about hx1500i.
    Can I expect some better results (coil whine wise) if i decide to take a shot and buy it?
    Is there a sugestion for other PSU unit then this.

    I’m pretty sure I’m not missleading here by thinking in the direction of the PSU and not the gpu. The very simple use case is the psu out of the pc case where its very clear that most of the whine is comming directly from the PSU.
    Thanks a lot.

    1. Are you sure it is the PSU and NOT the GPU? Because when you tried so many PSUs, and had problems. I believe you should also try another GPU. If you still want to try another PSU, try a be quiet! one.

  17. in case you are wondering the fsp hydro Ti pro 1000w is available as of sept 29,2023.. i bought one.
    now if I could solve the computer will not use more than 600w… uses 600w (for wall) when running furmark. but when i start prime95 the computer uses 450(or less) from the wall (measured using a belkin power meter… )

  18. Hello I turned my pc on after a few weeks of not using it and it made a loud bang and switched off. I waited few minutes and the pc came back on and everything seemed fine except the psu was making very very bad noise like a loud crying and screaming noise. The psu I had was an rm850x 2018 I believe and it was amazing I loved how it never made any noise. Anyways I managed to get it RMA’d but not sure what psu I should go for I have picked the rm850x shift but not sure if I should ask them to send me something else? My pc specs :
    Case – Lian Li 011D XL
    Motherboard – Asus Rog Crosshair Viii
    Cpu – Ryzen 9 5900x
    Cooler – Liquid freezer ii 360
    Gpu – Sapphire Nitro RX 6800 xt
    Ram – 32gb Tforce Xtreem
    SSD – WD_BLACK SN850 1TB
    Fans – 6 QL120

  19. Hello I had a rm850x the old 2018 one and it lasted me just short of 3 years.. .. I didn’t use my pc in a few weeks due to moving houses and then once I got everything moved I plugged in the pc and as soon as I pressed the power button I heard a loud bang and the pc switched off. I liked the rm850x it was almost completely silent but I’m not sure what I need now. I have managed to get it replaced and picked the rm850x shift was this a good choice or should I ask them to send something better thanksb

    My pc spec:
    Motherboard -Asus rog Crosshair Hero Viii Wifi
    Gpu – Sapphire Nitro RX 6800 xt
    Cpu – Ryzen 9 5900x
    Ram – 32gb Tforce Xtreem argb
    SSD – WD_BLACK SN850 1TB
    Case – Lian Li 011D XL

  20. Surprised to see a recommendation for an Aresgame unit on a list for “Best ATX v3.0 PSUs”. Their products are listed as “Replace Immediately” regardless of unit on cultists because of questionable practices and unit quality consistency. They are known to send a golden sample for qualification purposes, and reduce quality for general production. Units from Vetroo and SeaSonic were removed due to potential coil whine which is not consistent with every unit. HWBusters is a “go-to” source for PSU reviews, but this raises questions of legitimacy and consistency of reviews.

  21. Be Quiet Pure Power M 12 cable confusion.

    I have an AMD 7900 XTX being shipped. In preparation I went ahead an purchased the Be Quite Pure Power M 12 10000w. This video card, like most of the AMD 7900 XTX cards, states to use 3 separate PCI-e connectors. I noticed the PSU has two 12 pin to 6+2 cables and at the PSU, so thought I was out of luck since that would not be 3 sperate cables. However, I found a forum that mentioned the 12 pin cables allows the use of the pigtail without issue as it wasn’t a standard 8pin – 6+2 pin. But when I received my PSU, I looked at the cable and there are no wires in 4 of the in areas so looks to basically be an 8 – 6+2. Can this PSU not be used with the higher end AMD cards, or is there something I am missing here. Even the ThermalTake I looked at (GF3) only included 2 cables, so wouldn’t work out of the box with the AMD cards. Do I need to just return this PSU. Seems strange a newer PSU to not support one of the newer video cards.

  22. If I have a 13600k + 4070 system, would a NZXT C1200 overkill and power inefficient? For the price factor, it’s on sale (sub $180) from where I live so it’s actually cheaper than other 1000w PSUs. I use computer mostly for normal task and 30% of the time AI/ML
    I want to hear your opinion on this.

  23. Hi,
    I’m building a PC (13700k/4090) and want to select a ATX 3.0 PSU. The case will be NZXT H9 Flow.

    I’m thinking about following PSUs:
    – Corsair RM1000x (Shift) – $209 (Probably skip this one because the side cable interface doesn’t work well with NZXT H9)
    – New Seasonic FOCUS V3 GX-1000 – $209 (this is pretty new, I don’t see much reviews and comments about this one, does this have the coil whine issue as the Vertex one?)
    – NZXT C Series C1200 Gold – $229 (Not sure about the PSU quality from NZXT)
    – DeepCool PX1000G – $199 (need to wait for stock, also heard the cable is very stiff)
    – be quiet! Dark Power 13 – $289 (more expensive)
    – MSI- MEG Ai1000P – $279 (more expensive)

    Which one do you recommend or do you have other suggestions?
    Thanks!

      1. Thanks!

        I also found Montech Titan gold 1000 is $175, do you think the MSI and be quite worth the extra $100?

        Also for my build, do you think I need a 1200W PSU or 1000W should be safe?

  24. Hi
    I’m thinking about upgrading my psu because my current psu is causing crashes and I’m not sure which one I should buy. Which one of those would you recommend? Both the Thermaltake and the FSP are on sale right now.

    be quiet Pure Power 12 M 1000W – 147,14€
    Thermaltake Toughpower GF3 1000W – 154,81€
    FSP Hydro G Pro ATX 3.0 1000W – 167,79€

  25. Which PSU would you recommend?
    Montech titan gold 1000w
    Thermaltake Toughpower GF3 1000W
    Super Flower Leadex VII Gold 1000W

    or give your recommendation

  26. Which PSU would you recommend?

    My spec is
    Ryzen 9 7950x
    Powercolor Radeon RX 7900 XTX Red Devil OC
    ASUS ProArt X670E
    2 X 32GB ram 6000mhz

    Thank you.

  27. Hello,

    I would like to ask why there is no info of the FSP Hydro Ti Pro 850W, considering the 1000W is one of the best in the 1000 watt category. How does it stack up to the others in that category? If you haven’t tested this model or the FSP Hydro G Pro 850W, can we expect a test of them?

    Thank you.

  28. It’s a bit of a misunderstanding for me because there are some ATX 3.0 psu without a 12vhpwr connector, can I also use a 12vhpwr to 3 x 8 pin cable? at the moment I dont have a video card with a new connector, I wanted to upgrade soon.
    Thanks a lot.

  29. Hello,
    I can’t choose between them: XPG Core Reactor 850w and gf1 pe 850w, same price, same platform. Can I connect an NVIDIA GPU with a 12hwpr cable to this psu? The atx3.0 power supply is 30% more expensive. Could you help me please.
    Thanks a lot.

      1. I am planning to get
        Ryzen 7 7800X3D
        MSI MPG B650 EDGE WIFI (2 × 8 pin)
        Sapphire Nitro+ 7900 XTX (3 × 8 pin)

        Other PSU options I have are:
        NZXT C1000
        Corsair RM1000e (2021, non ATX 3.0)
        Corsair RM850x Shift (1000W option is 40% more expensive)
        MSI MPG A1000G (non ATX 3.0)
        Cooler Master MWE Gold 1050 V2 (non ATX 3.0)

        Which PSU would you recommend?

        Thank you.

  30. I’m planning a 7600X/7900XT system with the following:

    – 2x 16GB DDR5-6000 EXPO (1.35V)
    – 3x SSD (1x M.2, 2x SATA)
    – 1x HDD
    – may run PBO on CPU

    Power supplies I’m considering include:

    – EVGA Supernova G6 750W/850W
    – EVGA Supernova G7 750W/850W
    – Seasonic Focus GX-850 ATX3.0 (https://a.co/d/3xtgQ3d)

    Is 750W or 850W a reasonable PSU wattage?

    Are there other short (D = 140mm max) PSUs I should also be considering? Thank you.

    1. I would go for 850W, prefferably ATX v3.0 so the Seasonic.

      Most modern 750/850W PSUs are compact. Beware the smaller the PSU the tougher is to cool it down, and this is why most compact PSUs are also noisy at high loads.

      1. Thank you for the recommendation!

        I see that the Seasonic Focus GX-850 ATX3.0 has not yet received a Cybenetics rating. Has Seasonic submitted a sample for testing?

        Would the XPG Core Reactor 850W ATX3.0 be considered a competitor? This also hasn’t yet received a Cybenetic rating.

  31. Hello,
    Which psu do you think is better for 7800x3D/4090 build? My options are the following and I ranked them from cheapest to most expensive in where i live.

    Fsp hydro g pro 1000w
    Cooler master mwe gold 1050 v2
    Corsair rm1000x shift
    Msi a1000g

  32. Want to pickup ATX 3.0 PSU for a new 7800x3d/4090 build. I have had good success with Corsair however I think the Shift 1000w might be a tight fit in my Fractal North case with side cables.

    Is the HX1000i as good as the shift? Or should I look at Asus aura or something like that?

    1. The HX1000i is a category above the RMx Shift. If the latter’s side modular panel isn’t compatible with your chassis or gives you a tough installation time, you should avoid it.

  33. Hi,
    Which one to pick between Corsair RMe 1000W gold and NZXT C 1200W gold? Both are atx3.0 compatible, similar price.
    Corsair doesn’t include 12VHPWR module (why it that?).

    Also talking about high power port, I was looking for 12V2x6 PSU but can’t seem to find any. Do you think new standard will be backward compatible to these PSUs?

      1. I want to update on this. Got NZXT C1200 gold for $175. Heard nothing but good things about this PSU
        Unfortunately, this PSU has the worst coil whine I’ve heard, like a bird chipping in phase. Once you heard it, it stuck in your ears. As soon as you light load something (game, video), the noise is gone…

        Whilst price/performance is very good I don’t know if I want to keep it or gamble for another one…

  34. Hello,

    Is there a detailed review of the Asus Rog Strix Aura 750G/850G PSU anywhere?

    Its in the measurement tables, and recommended as rather silent. But i actually cant find a specific review article for it anywhere.

    I’m currently favoring this over Corsair RMx (shift), MSI A G and Toughpower GF3 because its at least good average everywhere in your data (its in all the graphs of the CM 750i review) but the quietest with lowest Ripple.

    One specific question though. As far i have read its CWT made while the Rog Strix was Seasonic made. Does it retain the same type of plugs on the PSU side though?
    Cablemods lists it compatible for its Asus/Seasonic/Phanteks cables, but that seems slightly odd if its not Seasonic made anymore.

    Thanks,
    and keep up your very informative reviews ! 😉

    1. I haven’t reviewed them yet, sorry. Will talk to Asus.

      PSUs are not electrically compatible usually, if they are from different OEMs, so be careful! Now if Cablemods says it is compatible, I guess the looked into this.

  35. Looking at the AMD 6600XT + AMD Ryzen 3900X
    Between Corsair HX1000i ATX 3.0 (2023) or Seasonic PRIME 1000 Titanium
    Open to Super Flower but only ever owned Corsair or Seasonic

  36. Im stuck with choices.

    Wich one would you choose from this list

    Seasonic vertex 1200 watt
    Fps hydro ptm pro 1200 watt
    Fsp hydro ti 1000 watt
    Corsair shift 1200 watt

    This psu im planning on using for at least 5 to 10 years.

    Is there any other atx 3.0 i should consider?

    I really want the new superflower but its nowhere to be found in europe. Do you know on how to get this psu?

  37. I have buyed a fsp hydro ti pro 1000w for 300 €. Do you think 1kw is enought for next generation CPU and GPU? Should i stay with it, or Look for something bigger?
    Dark power pro 13 1300w 390€. 1600w 426€ in germany. But there are no serious reviews about this units.

    1. You are right, there are not many reviews about these, and Aris is avoiding talking about them.

      While Bequiet on the phone were a bit “cryptic” regarding the 12VPHWR socket and possible future changes.

      Still at the 390eu 1300W Titanium sounds like a really great deal.

  38. Gonna repost here as it seems my comment went from waiting to be moderated to gone for some reason.

    currently im having restart pc problem that i think i can fix by changing to a more beefy psu.

    right now my pc is composed by: 4090, amd 5800x and a Seasonic Focus GX 850W.

    my pc restarts when im gaming (monitoring the wattage is like 600-700w at max) AND i have the air conditioner on. in the same room i have my gf pc that does not have this problem, i think because she has a higher quality psu ( asus rog 850w white edition) that has much higher wattage than needed for her system, while mine is barely enough with only 850w

    looking at your fantastic article i found these psu available on amazon.it which is where i can buy a psu right now
    Corsair RM1000e
    Corsair RM1200x (Shift)
    Deepcool PX1200G
    Montech Titan Gold 1200W
    NZXT C1200 Gold
    Thermaltake Toughpower GF3 1200W

    any particular psu you recommend for my issue? thank you

    1. From this list, the Deepcool, Montech, NZXT and TT units use exactly the same platform, so you can get the most affordable one! The Corsair RM1200x Shift is also good, but think if you need its side modular panel and if it is compatible with your chassis.

      Your PSU looks to be the problem, indeed!

      1. thank you! i went for the 1200x shift since i believe there is enough space in my case. i chose this one because it has low noise compared to others. I hope it’s enough to fix my problem, will update this comment with the results.

  39. I recently installed an air conditioner in my home and have noticed some voltage fluctuations. A clear indication of this is the momentary dimming of the lights in my room. Although these fluctuations are rare, they have caused my PC to restart if caught while gaming.

    Interestingly, my girlfriend’s PC, which is also in the same room, doesn’t experience these restarts. I suspect it’s due to her PSU’s superior hold-up time and quality. Her PC runs on a ASUS ROG Strix 850W White Edition, although her actual gaming consumption is around 500W.

    Here are my PC’s specs:

    Power Supply (PSU): Seasonic Focus GX 850W

    Case: NZXT H710i

    Motherboard: GIGABYTE X570 AORUS MASTER

    CPU: AMD Ryzen 7 5800x

    GPU: RTX 4090

    RAM: 4x G.SKILL TRIDENTZ NEO RGB 3600 MHz

    While gaming, my system’s power consumption ranges from 600-700 watts. When the AC kicks in or shuts off, I believe it induces a voltage fluctuation which my current PSU struggles to handle.

    With a budget of around 250 euros, I’m considering an upgrade to an ATX 3.0 PSU. Any recommendations?

    I did some research of course using this site, and from the best atx 3.0 list you provided in my area those are the psu ready to buy:

    Corsair RM1200x (Shift) -> 219 euro but im not sure if his lateral ports are ok for my case, in only have 3cm of space between the current psu and the lateral case door
    Deepcool PX1200G -> 224 euro
    Montech Titan Gold 1200W -> 270 euro
    NZXT C1200 Gold -> 209 euro but i read online lots of report for coil whine
    Thermaltake Toughpower GF3 1200W -> 230 euro
    Corsair RM1000e -> 170 euro seems the best deal but i saw a low hold-up time compared to the rest

    1. Replied to the first post 🙂 I noticed now that this is more detailed.

      According to the prices you mention, go for either the Deepcool unit or the Thermaltake GF3. They use exactly the same platform.
      The NZXT also uses the same platform, but they did some modifications for better performance and possibly this is the reason behind coil whine issues. In my samples I didn’t notice any, though.
