Hey I'm looking at getting an ATI 4890 and im not completly sure if my psu is up to it.
My system: CPU- AMD PHENOM II TRI CORE 720 Mobo- ASUS M3A79-T DELUXE GFX- 9800gt hdd- 500gb sata2 disc drive- dvdrw sata Ram- 2gig Wireless card
With a 500watt psu running it all would i be able to replace the 9800gt with the 4890 without problems?
More aboutgood enough
Depends what 500 watt PSU, please link to it. There are many good ones that would be able to handle a 4890, however most of them are cheap and beaten by good 400 watt PSUs or they are rated at peak and are only really 350watt PSUs.
