Cables and Connectors

As already mentioned, the flat peripheral cables are a distinctive feature to Seasonic made PSUs. For the CPU and GPU connectors Corsair uses the usual cables and sleeving, and every surface and single connector are classical black.

Cables and Connectors
Modular Main 20/24-pin 60cm
ATX12V/EPS12V 4+4-pin 60cm / 4+4-pin 60cm
PCIe 2x 6/8-pin 60cm / 2x 6/8-pin 60cm
Peripheral 2x Molex: 45cm / 58cm / 71cm / 85cm
2x Molex to Floppy 10cm Adapter
2x SATA: 45cm / 58cm / 71cm / 85cm
2x SATA: 45cm / 60cm

Cable lengths are reasonably long and the AX750 should work well in most cases, including full towers with bottom-mounted PSUs. The main 24-pin, 4+4 ATX12V/EPS12V, and PCIe harnesses all measure 60cm. There are two Molex/PATA and SATA harnesses with four plugs each, and two additional SATA harnesses with two connectors each. The longer harnesses are 85cm total while the two shorter SATA harnesses measure 60cm. With modern systems, Molex connectors are primarily used for fans and other peripherals, while SATA powers the HDDs/SSDs and optical drives.

The only potential issue is if you want to load up all the SATA connectors with a bottom-mounted PSU; the distance from the PSU to the first connector is only 45cm (give or take), with a fairly large 12-13cm gap between the connectors, so you'd want the HDD bays to be relatively close to the PSU rather than in the top portion of the case.

    And this thing is amazing. The silence is simply incredible! Best PSU there is IMO.

    I have horrible squealing when I have high FPS in games (game menus especially) or other type of GPU load. I believe it is a combination of my PSU and graphics card. I've tried two cards and two psus. GeForce gtx 285 and gtx 470 both squeal much more with a Mist 650W rev 4.0 than the Mist 650W rev 3.5. The only difference is that the rev 4.0 have one 50A 12V rail while the quieter rev 3.5 have four 20A 12V rails.

    The mists are known to be squealy I heard, but how about the Corsair AX750 80 Plus Gold? Can you try it with a few recent 3d cards? I'm looking for a quiet psu/gpu combo.

    Thanks for the review, great as always. I will be getting this PSU in my new build for sure.
