I have a Hp p6213w which i bought in 09, with a 21.5" display. It has a IPIBL-LB (Benicia) motherboard and an Intel Pentium Dual Core E5300 processor. I was wondering if it is compatible with Corsair CX600v2 psu that i bought for the Sapphire Radeon Hd 6870 1g gddr5. Can you simply put any power supply on any mother and processor?
