Corsair SF750 Platinum power supply

We put the new Corsair SF750 Platinum power supply on our test bench today. It’s the most powerful model in the Corsair SF series. There are also variants with less power – a 600 and 450 W ones, both also with 80 Plus Platinum Certification. This is important because the energy consumed does not go to waste (at least not in a significant amount), and this affects your energy bill. The Corsair SF750 Platinum is a small form factor (SFX) power supply, but it’s still possible to install it in ATX systems. It comes with 80 Plus Platinum certification, which means that it’s 92% efficient at 50% load @ 115 V, and even 94% efficient @ 230 V. It seems to be an interesting product for people with HTPC chassis who need an efficient, powerful, and reliable solution.

It’s a fully modular PSU, so even the motherboard connectors are not attached permanently (but you still have to use them, correct?). This feature is not really necessary, as an increasing number of cases are now fitted with a power supply shroud (at least ATX-sized ones), but it’s still easier to manage cables this way. The fan works in hybrid mode (semi-passive), so you should be able to achieve a very nice acoustic experience. The fan size is 92 mm, whereas the entire power supply measures just 128 mm. The fan uses FBD bearings, and it’s controlled by a temperature sensor. The SF 750 Platinum is built with 100% Japanese 105℃ capacitors, so you can really count on the reliability of this unit.

Corsair’s SF750 Platinum is backed by a 7-year warranty. This is a good offer, but Seasonic provides even twelve years of warranty for their Prime series and 10 years for their Focus SGX model (the same PSU format as the one reviewed here). MSRP is about 149.90 EUR. Ok, let’s check out this SFX PSU from Corsair, shall we?
