My question is that recently my 6870 has been lacking.... So i thought i would revitalise my build with a stronger graphics card and have been looking at the ASUS HD 7970 Direct CU II, however will my PSU be able to handle this? with my current set up of course.
More about650watts enough
That should handle a single 7970 just fine, but of you ever add a second you'll need a bigger PSU.
