Date Issued: 18th Nov 2010

Conceived back in 2004 and brought to market just a year later, the 80 PLUS initiative is one of many standards introduced in an effort to increase energy efficiency in modern technology. Targeting computer power supplies, it awards PSUs that are able to achieve an energy efficiency of over 80 per cent at varying workloads and a power factor of 0.9 or more at 100 per cent load.

450W Corsair SF450 High Performance, 80PLUS Gold, Full Modular, SLI/CrossFire, Single Rail, 37A +12V, EPS 12V, 92mm Fan is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Great product and price Got this to put in an Ncase for a mini-itx build as a low power NAS/Server. Its a perfect fit for the Ncase without obstructing a graphics card. When powered up it is truly silent, no fan noise, no coil whine. There is a single 'tick' when first powered up - something to do with the internal switching components maybe ? Nothing to worry about though, it only happens once at startup. Build quality is really good, the cables are perfect to fit in a mini-itx case but you may struggle if fitting to a larger case. My only minor issue is that on the SATA power cable, which has four connectors, the first connector is only around 3-4 inches from the PSU connection. I had to get creative to use that first connector and mount my drives as close to it as possible. Overall, a great product and thoroughly recommended. The price is also very good given the quality of the unit. I replaced an SX500-LG and couldn't be happier :)

Rated 5 out of 5 by from Completely silent. This power supply is great for low-power machines, because the fan doesn't actually spin until a certain wattage is reached. So, with the appropriate hardware, you'll never hear this thing, literally. There is some false information on this page, however - it's NOT an ATX power supply. It's an SFX power supply. This means if you want to use it in a case with a space for standard ATX PSUs, you need a special bracket.
