Whats the rest of the rig?
For instance AMD chips often have a 125W total draw while recent Intel's only have 77W draw.
But it should be fine (cutting it close though).
thank you for your quick reply my rig:
4 gb ram ddr3
i5 2500k cpu
19" lg monitor
mobo (not decided yet)
as far as i know is that gtx 460 required 2 pin connectors does any psu have them?
Any PSU above 400W should have PCI-E connectors. Though for an Intel single GPU system, I would say get a 600W supply. Especially as the GTX460 isnt as efficient as modern cards.
