Stop trolling.
I've done the research. Dell PSUs are actually not crap, and my PSU is more than enough to handle both the OCing of the CPU and the GPU.
Obviously you haven't done your homework. how old is that Dell PSU 2-3 years. If you did your research you would see PSU's as well as everything else degrade over time. I'm sure a new 305 watt PSU would run your piece of shi t if it were new and everything was running stock. Drop the GPU in your other rig, if it works, then get off your high horse and buy a real PSU.
If you had done research you might have come across this:
ATI Radeon™ HD 4600 Series – System Requirements

Oh wow 400watt with stock speeds, what a noob. Talk about trolling. Go buy a PSU and get a life idiot!
