Don't Know The Problem

[[TC]»Elmo«]

Cheap brand PSUs are pretty much always over-optimistic about how much power they can produce. The wattage stated on cheap ones is usually peak, rather than continuous - Quality PSUs quote continuous power.

I have a cheap EZ-Cool "650W" PSU that can provide less 12v power total than a single rail on my OCZ 550W PSU. The OCZ has three 12v rails capable of providing up to 480W total @ 12V.


Your system would actually be just about OK with a 400W high quality brand PSU. For some safety headroom, aim for a 500-650W Antec, Corsair, Enermax or OCZ.

Something like this: http://www.ebuyer.com/363095-ocz-500w-co...cxs500w-uk
or this: http://www.ebuyer.com/264509-ocz-zs-seri...-zs550w-uk
should be plenty.

(I haven't shopped around to see if there's anything cheaper, but those are the type of specifications you're after)
