Hi,
I recently purchased a new Dell XPS 8500 ( intell core i3 ) computer. ( still being processed) My question is ~ will my graphic card AMD Radeon HD 7770 be ok with a Dell 460 W power suplly? It did allow me to configure it in, so I am guessing it can handle it???

Thanks! :)

Thanks for the quick reply.
I was searching the web and found that a few people were having problems with it. Apparently, AMD specifies a power supply of at LEAST 500w for the 7770. So I was a bit concerned....

On the Dell? or their custom build PC?
Because Dell would tested it to make sure it configuration would run.

That wattage number is useless. The wattage rating of a PSU is almost irrelevant. What matters is +12V amperage and build/cooling quality. If that's the 460W PSU that I think it is that you have, then you shouldn't have trouble with two 7770s, let alone one of them.

Yeah, AMDs quoted number is padded significantly to account for different potential system configurations and to account for the lowest common denominator among power supplies. While the Dell PSU is probably not a top of the line 460W, it should be plenty for the PC, if you have access to details on the PSU specs, if it's got a 20A supply (240W) for 12V it would have more than enough (you could also post them here, to be sure)

I would assume dell also does testing to ensure they are sufficient, but it doesn't hurt to be sure.
