Corsair SF750 (2024) ATX v3.1 PSU Review

Efficiency Normal, Light & Super-Light Loads

Efficiency is high at all load levels.

Average Efficiency

The platform’s average efficiency is high!

Average PF

The APFC converter needs tuning for higher PF readings at 230V.

Average Efficiency 5VSB

The 5VSB rail is highly efficient.

Vampire Power

Vampire power is low at 115V, but I want to see below 0.1W at 230V.

  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.

    2. 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)
