Simple question.
I overclocked my i5 2500k to 4.5ghz the other day at 1.248 core voltage.
Everything seems to be running smooth.
This is my PSU http://www.newegg.com/Product/Prod [...] 6817371016
Is it's wattage kinda low for this overclock? I'm not sure how to tell as it's been running fine.

Should be fine.
More dependent on GPU, but should be fine for a single graphics card. For daul cards in SLI/XFire configuration you would be pushing the limit.

My I5-2500k @ 4.2 with a ATI 6870 is around 350 Watts, bumping up to 4.5 and a Vcore of only 1.25 is not going to add much.
