The only SFX unit that matches—actually surpasses—the SF750's overall performance is the SF600 Platinum. Although with 150 W less power output, it achieving better performance in some areas isn't surprising, like load regulation on the minor rails and ripple suppression. However, while it trumps its smaller sibling in power density, the SF750 also has the better cable configuration since it is equipped with twice the EPS, PCIe, and SATA connectors.

Clearly, the Corsair SF750 can power a strong gaming system, and as I have already stated earlier, it should be sold in two versions: with the normal, short cables or longer ones. With the bundled SFX-to-ATX adapter, users can use this PSU with a normal ATX chassis, but the short cables set the limits here. However, why use an SFX PSU in a regular chassis? Well, for starters, simply to be able to! Each and everyone of us has different needs, so there are those who for their own reasons would prefer to use an SFX PSU with a normal chassis, and given Corsair already provides the required adapter bracket, it would be nice to have the option of going with longer cables as well.

There is no doubt that the SF750 is among the best SFX units available on the market today, as its overall performance is only slightly worse than its lower capacity sibling, the SF600 Platinum. Since nothing is perfect, though, I would like to see a couple of improvements implemented. The most critical of these is to increase the hold-up time to at least the 17 ms the ATX specification requires. I know that it is hard to put properly sized bulk caps into such a compact unit, and it will probably take a completely redesign of the PCB layout because space is a real commodity, so I won't hold my breath for it. The second notable downsize is that you can't deactivate semi-passive mode. In several cases, you have to install the PSU sideways or with the fan grille facing downward, which requires the fan to constantly operate to avoid hot air from being trapped internally. In the SF750, the fan will start to spin at some point, but internal heat build-up is quite significant until it does, which puts a lot of strain on such sensitive parts as the electrolytic caps of the secondary side.
