Sometimes, you don't need a thoroughbred, you just need a sturdy workhorse. With a rating of 100K hours Meant Time Between Failures (MTBF), this plucky little supply from Silverstone is just such a workhorse.

Possessing an output of 400 Watts at >70% efficiency, this supply is also inexpensive enough that you could buy a couple of extras as emergency spares. Not that you're likely to need them for years. Dual +12Vdc rails for clean and even distribution of power, this ATX-compatible supply has a 120 mm silent fan to keep it cool without roaring like a jet engine. Four SATA connectors and one PCI-E connect support modern equipment as well as older models.

So, if you need a tough little supply at a good price, this could be the one for you. Check it out and decide for yourself; we'll be right here when you need us.
