  1. hi, i need to buy a power supply for my new build:

    9800x3d and rtx 5090

    what do you recommend between seasonic noctua edition and asus rog thor 3?

    or alternatively something else that is comparable to them in terms of efficiency and silence?

    thanks

  2. Hey,

    thanks for the great article.

    You have a typo on the 1000W power supplies page “Highest Average Efficiency (1230V)”.

    Regards
    JR

    1. Hi! My main PCs are not for games, since I barely have any time to play games anymore 🙁 So I use a Corsair SFX unit in my main PC. In my previous PC I had a Corsair RM750x. In my test PCs I currently use Seasonic Vertex GX-1200 mostly because I had several of them (and I needed to have exactly the same PSU on all of my test benches). Truth be told, they never gave me any trouble. In general I tend to prefer efficient units in general.

  3. Hello there! I got to say thank you for the list and for helping the PC community. I’m building a PC, and I’m planning to get 5090. I bought Rog Thor II 1200W in the summer with the plan to get 4090, but I decided to wait for the 5090.

    Will this PSU be enough or should I get another? I’m browsing through the comments and I saw that you value AsRock.

    Thank you!

  4. Hey Aris! Watched your latest videos and now I’m wondering which PSU should I go. I recently made a build with 9800x3D and 5090 RTX and considerating the melting cables issues I wanna be safe as much as possible. I was considerating the NZXT C1200 but now I’m unsure. Can you help me decide?

    GPU: 5090 RTX
    CPU: 9800x3D
    RAM: G.Skill Trident Z Neo 6000mhz CL30 – 64gb
    HDD x1
    SSD x1 (Samsung 990 PRO)

  5. Do you plan to retest the FSP Hydro Ti Pro 1000 (ATX3.1)? I really want to buy this PSU, but a little worried because sometimes manufacturers make internals cheaper over new iterations 🫣

    Thanks for your great work!

      1. Yeah, I know about box label discrepancy 🙂 My concern is that in addition to the 12V connector, they may have changed some internals to make them cheaper, and if so, the PSU will no longer work as well as in your review. That’s why I asked about retest.

  6. Hey man, yoyur video brought me here, really appreciate your work!

    I am wondering which 1200W+ PSU to choose.
    Currently running Ryzen 7 7800X3D and RTX 4090 FE. 4K gaming on an OLED TV
    Will probably want to upgrade in 2 years, hence the overhead power.
    Currently deciding between these, but feel free to suggest something else 🙂
    1. SeaSonic Prime PX 1300W
    2. Super Flower Leadex VII XG 80 PLUS Gold 1300W
    3. MSI MEG Ai-P 1300W
    4. be quiet! Dark Power Pro 13 1600W
    5. Seasonic PRIME TX -1600 Noctua Edition

    Can you help me decide?

  7. I’ve paired the Leadex VII XG 1000W with the 5080, a week of heavy use later no issues so far. Loved your review on it as well, why isnt it in the list though?

  8. Hi first of all great work and kudos for your dedication in a niche area which has always been very confusing!

    Recently had a bad luck with the NZXT c1200 blew up within 10 days of use tripping my breaker which is really odd though it’s quite frequently mentioned in your top recommendations.
    I am finding a good deal on the Cooler Master MWE Gold 1050 V2 ATX 3.0 and I see this and the ATX3.1 version appearing in your performance charts but I couldnt find any review of this on your website or YouTube channel?

    Looking at the charts it’s usually in 10-15 on most of the charts. There is also not much information about this particular model.

    Would you recommend this PSU. Thankyou in anticipation. Keep up the good work

      1. Thanks for your response Aris. Once again keep up the good work.

        I can imagine the CM must be inferior to the NZXT ones hence cheaper and all PSU can fail luckily my PC survived!

        Can I use the charts you have kindly have posted to have a rough idea of the cooler master mwe gold ATX 3.0’s performance or there are variance between the 1250W and 1000W models too?. Just very scared to get the CM master as havent every used their PSU!

  9. I am currently a bit thorn of choosing a asrock tc1650 or a asus thor iii 1600 as my next psu. However it seems the Asus isn’t in the charts at all? I cannot seem to find any reviews about that gpu first function that Asus has included aka if it’s working or that it’s just a gimmick/marketing material.

    For the Asrock it has some temp guard thingie on the 12V-2×6 cables seems I cannot find any tests of that as well.

    Thank you for the great tests/reviews you provide!

  10. Any chance you could add your thoughts about the newer 3.1 Thermaltake SFX 1000W Platinum? Cybenetics has a report already, and it’s the sole competitor to the Corsair SF1000 in the true SFX form factor at 1000W. Everything else is either an SFX-L or lower rated power. Would really appreciate it!

    Also, one other question if I may ask. In theory, given that the innovation of the 12V-2X6 connector is the inclusion of the Sense Pins (particularly the 3.1 spec), wouldn’t it be a safer choice to always use a native 12V-2X6 connector on both ends to ensure its benefits at all times, rather than just on the GPU side? For example using a Type4/Type5 connector on the PSU side (like on the SF1000)?

  11. Hey! It’s weird that the DeepCool PX1000P didn’t make the “1000W PSUs” list, though it had a “recommended” badge in your review. Is there a reason not to include it?

  12. Hello, i have the Seasonic Focus GX ATX 3.0 (2023)

    Will it be fine for 9800X3D + Asus Astral 5090 + 2 nvme + 7 P14 Arctic fans?

    Not 100% sure if i should keep it or return the PSU and get a better one?

    Thanks!

  13. Maybe obvious, but then again… I currently have Corsair AX1600i and have new build on the way. My new build will be Ryzen 9950x3d/5090OC/M2.Nvme disks.
    Should I use my two year old AX1600i for the new build? I have Asus ROG Strix 1200W Platinum new in a box as well…

      1. Thank you, I have the whole box and cable-kit. Just didn’t get quite confident regarding 3.x or this new cable that Asus have for their GPU. I’ll switch then 🙂

  14. Hello,
    Currently planning a build with a 5090 and a 9800 x3d (atm rocking a 1080).
    For whatev. reason the FSP Hydro PTM PRO ATX3.1(12V-2×6) 1650W is cheaper here than any 1200w platin 3.1 PSUs.
    Is this a good one or should it be avoided for being bad / very loud or something? thank you very much in advance!

  15. Hi, I’m confused on these super flower PSUs. In another thread I thought I saw you say the PRO is the renamed XP, but in the list I see the XP, XG, and the PRO (with the PRO below the other two overall). On Newegg the PSU says “XP PRO” so is this the 3rd overall on the list or the one lower down? Thanks

  16. whould love to see your opinion on this Abysm Morpheo GX5 1000W it is made by helly and its 80 plus gold and cybenetics platinum, from what i research it apears to be the same platform they used with deepcool PQ

  17. It is surprising to see that neither the Seasonic PX-1000 or GX 1000 made any of your categories for top 3 pick in the 1000 watt power supplies. would you recommend the NZXT C1000 Gold over a Seasonic GX-1000, considering their reputation for making solid power supplies?

  18. Hello, which one should i choose HCG extreme/gold or Rme 2023 850W?
    My current rig is :
    Ryzen 5 7600

  19. Hi..which one is the best between FSP Vita GM 850W and Super Flower Leadex III Gold 850W ATX 3.1?
    My rig is :

  20. Hello! I am building a pc with intel 12700k and AMD 7900 xt (sapphire pulse), 32 GB ddr5 ram, and 3-4 ssd. What is the best power supply out right now for what I need?

      1. I have a deepcool PX1000G (old rev atx 3.0) with a 5800x3D and a 4080. Worried about my gpu melting when I get a 5090. Is that a concern and should I swap it out, or is it fine?

          1. Any chance you could add your thoughts about the newer 3.1 Thermaltake SFX 1000W Platinum? Cybenetics has a report already, and it’s the sole competitor to the Corsair SF1000 in the true SFX form factor at 1000W. Everything else is either an SFX-L or lower rated power.
