Corsair SF750 (2024) ATX v3.1 PSU Review

The Corsair SF750 (2024) is the lowest capacity member of the upgraded SF line, offering ATX v3.1 compatibility and enough power to handle a potent gaming system, since it can cope with up to 1500W power spikes. 

The Corsair SF750 will be included in my best ATX v3.x & PCIe 5.x PSU picks article.

It was high time for Corsair to enrich its SF line with stronger and ATX v3.1 (SFX12V 4.1) compliant members. Before this upgrade, the SF750 was the strongest member of the line, but it is the lower-capacity one in the upgraded SF series. The significant difference between the previous generation and the new SF750 is that the latter supports the ATX v3.1 spec and comes with a 12+2 pin connector capable of delivering up to 600W of power.

To increase efficiency, make the platform more reliable, and save money, Corsair decided to ditch the -12V rail in these PSUs. This was a wise move since no PC part requires this rail anymore, which is a remnant of the past. Every PSU manufacturer should eliminate this useless rail as soon as possible.

I have evaluated so far the following SFX and SFX-L PSUs:

  1. I do apologise, there’s not much information right now but for clarity, the landing page for the updated sfx psus state as such…
    sf750 – 2x pice 8 pin cables
    sf850 – 3x pice 8 pin cables
    sf1000 – 4x pice 8 pin cables
    Can you confirm that the new sf750 actually does include 3x pice 8 pin cables?
    This is a concern for me.

    1. It has two 6+2 pin cables, as I have in the cable description table, and one 12+2 pin.
      I found that there was a typo in the general specs list, fixed it.
