I got a no brand 450watt psu
And thing is i bought the r7 260x in December just having second thoughts
wut??
you already bought it in several months ago and want to compare two of them now? are you planning a crossfire with that crappy psu?
first thing you have to do
1) thank god. because he helped you to run your gpu on a crappy psu.
2)change the psu to a better one asap
3)be happy with what you have got. sit,play and rest.
