PSUs (Power Supply Units)
Date Issued: 4th Jul 2011

Let's face it, power-supply units (PSUs) are boring. Presented in what's usually a mundane box spitting cables from one end, this is a product that's neither aesthetically pleasing nor technically interesting to the majority of self-builders.

300W Seasonic SS-300SFD SFX, 80PLUS White, Fully Wired, Dual (2) Rail, 22.5A +12V, 1x 80mm Fan is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Great replacement PSU for my Netgear Readynas Does what it's supposed to do, and is a drop in replacement for the faulty one in my NAS. All good. Just works

Rated 5 out of 5 by from Exceeding expectations.... When my Silverstone PSU died suddenly, leaving me without my primary system, I had to choose a replacement quickly (school work to do and all). I struggle to spend money in any great quantity and so after weighing up the pros and cons and looking at a review from 2005! I went for this one, the cheapest ITX PSU I could find. Fantastic. It fits my Silverstone SG05 perfectly, provides all the power needed (A10-7800, Crucial SSD and ODD) and does so quietly. Not silent but in a house with 3 children under 16 I am unlikely to be disturbed by the quiet hum of the fan. I suspect that if I had a dGPU I would have had to look to a more powerful PSU but as it stands this was an absolute steal!
