The Corsair AX1600i has the best overall performance, but it is not ATX v3.x compliant. Since the Salcomp ATX 1600W unit is not available for purchase, I only included it in the charts for reference.

  1. 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?

  2. 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?

      1. 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)?

  3. Where is the review of Lian Li Edge 850W?

    It has interesting design and has excellent scores even topping Transient Response.

  4. 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

    1. 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
