Is this OEM PSU enough?

[noblezero]

I have a Gateway-

Gateway FX6800-01E
Core I7-2.66 GHZ
3GB RAM
ATI 4850 -512 MB

I swapping out the GPU for a EVGA 560ti 1gig and doubling up the RAM to 8gig. Will my power supply be enough? It was supposedly 500w, but I cracked open the computer to check it out and the PSU is a LITEON ps-6451-2. It says peak at 500w and total ouput be no more than 450.

Yep that PSU will be enough, but you may want to switch it out anyways because OEM PSU's are usually crap.

The extra RAM won't use much power. The graphics card... probably uses another 50W at most. I'd say you are okay.

U r OK since your CPU is not overclocked.
