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.

Hello,
For battery backup do you think it matter if is a Simulated Sine Wave or it need to be True Sine Wave power supply.
Trying to decide which version to get as I don’t understand at what testing data to look to decide.
Thanks
most PSUs I tried don’t have a problem with simulated sine wave as long as you only need the UPS to hold for a small period to shut down your PC.
That good to know.
Is for a 810W I saw that is supposed to run for 10minutes half load and I guess the PC would be using 400-450watts.
So 2-5 minutes to shut it off should be safe then.
Thanks
What do you mean by “Micro Fit” connectors? As I am only seeing mini fit Jr connectors on this psu?
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.
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.
Can confirm my retail unit comes with only 2 x 8(6+2)pin cables, and that cables are singular they don’t have pigtails like the old unit. If you need more than two 8pin for your GPU like for higher end factory overclocked RX 7000 units you need to get SF850.
Personal opinion: even in the old unit those pigtails power generally doesn’t provide good enough power for long term use and also it is generally accepted convention to not using pigtails for powering many pinned GPU. I guess corsair can get a pass not providing pigtails this generation as it will reduce user error and we are moving forward to using new 12V-2×6 standards anyway (side note: these new SF cables are very good and flexible even better than the old generation, this is especially valuable for SFF build with tight cable management restriction)
