Most video cards should work on your epox board. Check your power supply specs against the video card spec for the 12v rails. Most mid range cards will work with 18-22 amps. Corsair is the best ps with a high single 12v rating. Also be sure your ps has the pci-e 6 pin connector. An adapter is available if needed for older ps. The 5770 is a good video chipset if your ps can handle it.
