Xps8500 only have 460w power and radeon hd 7870 requires at least 500w power.
So I'm planning to buy a new 500w power supply to meet the power requirement for my new graphic card.
I opened the xps8500 case and found out space for power supply is quite small.
The power supply that I'm going to buy is Corsair CX500 watt ATX/EPS 80 PLUS.
The dimension of this power supply is 5.5 X 5.9 X 3.4 inch.
Will CX500 fit in the xps8500 case if I take out the 460w power supply and replace it?
