The Salcomp ATX 1600W has the best overall performance; however, since this unit is currently unavailable on the market, I have excluded it from the table above. The same goes for the Zhong Yuan Power GX850, which has the longest hold-up time. Lastly, the Corsair AX1600i is included only as a reference, since this is not an ATX v3.x compliant PSU.
Overall Performance 115/230V
Average Efficiency 115/230V
Average Efficiency 20-80W Range – 115/230V
Average Efficiency Ultra Light Loads (2%) – 115V

Terrific works, Aris. Best overall budget 650w PSU around $60?
prices change contantly and new offers emerge daily, so it is hard for me to suggest something based on price. I cannot follow closely pricing schemes, sorry.
I understand. Is PL650D a good choice in this regard? Or would suggest something else? It’s going to power a 5800x and a 3070. Thanks.
For this system it will be fine!
Hi Aris, between corsair RM850X and nzxt C850 (both atx3.1 and same price) which one you recommend?
I would go for the RM850x most likely
Thank you for the reply Aris!
The purepower 13 review hyperlink has the wrong target.
That is the 1000w.
Hi Aris,
I have a Asus 5090 Tuf and a i7 14700k. What would your top pick be for a 1200 watt psu if you had to choose? I can’t make a decision 😵💫
One of the top three in my charts at 1200W 🙂
Which one of those 3 would be your top pick though? That’s what I can decide.
Are there any PSUs these days that have built-in Surge Supressor, power spike protection, or will that always have to be external such as a good surge protector plug strip?
Almost all PSUs have MOVs, for surge protection.
Hello,
Where is the Corsair HX1500i power supply review (ATX3.1 / 2024 (model CP-9020261) or 2025 (model CP-9020309) version)?
You provide results in tables and rankings for this power supply, but the only review of this power supply on your website is of the first version from 2022, which isn’t even an ATX3.X power supply.
FOR EXAMPLE
The 1200W version (2025 model cp-9020307) is reviewed here: https://hwbusters.com/psus/corsair-hx1200i-atx-v3-1-2025-psu-review/11/
The 1500W v1 ATX2.53 version from 2022 is reviewed here: https://hwbusters.com/psus/corsair-hx1500i-review/
So why do you list the results of the ATX3.1 model (2024 or 2025) in your rankings?
I don’t have to review something before I add it to these graphs as far as there is data for it already available in Cybenetics.
Thanks for the reply.
So, I have another question (I’ve already contacted Cybenetics, but haven’t received a response. Maybe You can help).
The Cybenetics report (https://www.cybenetics.com/evaluations/psus/2099/) of the Corsair HX1500i power supply is dated on December 7, 2022. The report includes a graphic stating that the power supply meets the ATX3.1 requirements. The report doesn’t even specify which model was tested (probably the Gen 3 from 2023 – cp-9020261????).
This is a bit strange, as they updated the 1200W version (HX1200i) in their database, indicating it’s the 2025 version (cp-9020307).
My question is: according to the Cybenetics report (from 2022), the starting INRUSH CURRENT for the HX1500i model (but which generation, model???) is 91.12 Amps, and for the HX1200i model (2025) (https://www.cybenetics.com/evaluations/psus/2733/) 11.12 Amps…..
Isn’t that too much for a 1500W model? Why is there such a big difference between the 1200W and 1500W models? How can I find out what the “inrush current” parameter is for the 2025 model (cp-9020309)?
Cybenetics replied to you already. I know first hand. Please post any follow up questions on our discord.
Lately I have been seeing reccomendations for the Montech Century ii gold psus. Any info on it? 850w/1050w/1200w

Where is the review of Lian Li Edge 850W?
It has interesting design and has excellent scores even topping Transient Response.
I don’t remember the reason I haven’t reviewed it, sorry.
Hi Aris, first of all thank you for your efforts. Which one of these units do you recommend?
The price of these 3 is the same in my region.
Lian Li EG1200G
XPG Core Reactor II 1200W
Gamer Storm PX1200g
XPG most likely.
Why is there 2 Corsair HX1200i(ATX 3.1) in the list. What is the difference of those units?
It’s probably a 2025 rerelease with extra ports for Dual 12V-2×6 cables.
UK part number for 2024(?) version is CP-9020281-UK and for 2025 version it’s CP-9020307-UK
I made this video because of you Aris.
