The Corsair SF1000 is not only the best SFX power supply I have ever tested, it is also one of the finest power supplies on the market today. Corsair's partnership with Great Wall is reaping dividends – Corsair can confidently claim that for the small form factor market, this is the ultimate PSU you can currently buy.
The Corsair SF1000 excels in a wide array of tests, with only ripple suppression falling inside parameters we would label as good, rather than exceptional. It is not a concern however, as the results are still well within industry rated parameters.
Load regulation scores well and the unit achieved 80 Plus Platinum levels, and considering the small form factor and overall performance, it is difficult to not be impressed by these results today. It is also important to note that this unit also achieves Platinum approval from Cybenetics and really everyone should value them more now than the dated, somewhat dubious 80 Plus ratings.
SF1000 noise emissions are relatively decent until the upper end of power delivery. This is not the quietest power supply you can buy, however this is always going to be a trade off with a small physical unit incorporating a 92mm fan, rather than 120mm or 135mm equivalent. A smaller fan at any given speed – if quality is consistent between the models – will always generate slightly more noise than a larger fan. It is unavoidable.
Right now you can pick up this power supply from SCAN in the UK for £199.99 HERE. I consider it a good value purchase as it targets a market which sometimes gets overlooked by other brands.
