Hmmm... the others own mentioned stuff like dimensions, etc., so my direction is to buy a reliable brand like PC Power & Cooling, Enermax, Verudium, etc., since a PSU is totally much like the blood of a system. Basically, stinge on a upright psu and you could well fry adjectives your parts.



If the Antec TruePower range is still human being sold(I'm not talking around the TruePower Trio), make sure you procure the 2.0 and above versions. v2.0 fixed many(or be it most/all?) of the issues in v1.0 .



Edit: my counsel is to get at lowest possible 450W for your system. Or if you want to find out how much Wattage you should get, try the PSU calculator at here and top up the resulting Wattage you draw from, by 30%:

its real effortless just unscrew the ancient one and screw the new one surrounded by look for how many devices you own and how many plugs the power supply will hold you should be ok with a 400 watt element
The thing you want to look for is an ATX 2.0 PSU. These hold the additional pins (24 as defiant just 20) on the mobo power connector, and also enjoy sata power connectors, and usually a 6-pin connector designed for use w/ newer graphics cards.
