The SF750 Platinum version includes the braided cables, which aren’t included with the Gold rated SF750.Īs we have mentioned before, 750W will be overkill for most builds – and hence if you don’t need this extra wattage, we recommend going for the 600W version of this SFX power supply in the SF range – the Corsair SF600 Platinum that we have covered earlier.Look on this list - tier A or better are the good psus for gamingīrand doesn't mean anything as pc psus often are made by third-party electronics manufacturers.Ī quick estimate with 16gb ram and 5 drives recommends a 511W psu. If the SF750 Platinum is too expensive for you, the SF750 Gold rated version offers very similar levels of efficiency under any load, but we personally recommend that the $30 difference between the SF750 Gold and Platinum it is a no-brainer to opt for the Platinum rated version. The SF750 Platinum is ultra silent with 0dB operation up to 300W. The Corsair SF750 Platinum has best in class power delivery, efficiency and reliability when it comes to SFX power supplies – Corsair really does dominate the SFX power supply market with its SF series. This power supply will be overkill for 99% of SFF builds, but if you’re looking for the absolute best SFX power supply for SFF builds that may contain power-hungry components such as the RTX 2080 Ti, Threadripper or Core i9-9900K build – then we recommend no other SFX PSU than the Corsair SF750 Platinum. We actually recommend the gold version since it is slightly cheaper and the non-sleeved cables actually are a bit easier to work with and more flexible – very useful when building in a SFF enclosure. The difference between the Gold and Platinum rated versions of the SF450 are minimal – with very similar levels of efficiency and the Platinum version includes sleeved cables that the gold version does not. The Corsair SF450 will be a suitable enough wattage for any single GPU setup – you should only look at going for a 600W PSU or greater if you look at running a dual GPU setup or want complete peace of mind regarding TDP’s. This SFX PSU offers best in class performance with impressive power delivery and efficiency levels, whilst super silent under any load. What is regarded as the best SFX/SFF PSU on the market for most mini ITX builders is the Corsair SF450 Gold. Power supplies with 450W wattage are used by most SFF builders for these mid range builds – and still provide a great reserve of power for when the SFFPC is under load.

Low to mid-range (and even some high end) SFF builds will not require wattage north of 400 watts, and hence if you are on a budget then there is no point going for a 600W or greater SFX power supply since it won’t be necessary.
