hey everyone, I was hoping for some suggestions on power supply size for a new system a friend has built Leadtek WinFast K7NCR18D-Pro mobo AMD Athlon XP 2400+ ATI Radeon 9500 Pro (128meg) 512meg DDR 333mhz Originally he had only 250w supply (from his old case) and the boot process wouldnt go beyond memory check. He then went to Circuit City and they convinced him 300w was enough. The system now boots, but the graphics are completely garbled. Is 300w enough for this system (my guess is no). And would that be the cause of the garbled screen? Its all distorted, with random color blocks, shifting parts, random characters, missing blocks, etc. It still runs ok, as in it can boot, and I can go into bios (havent loaded an OS yet) and move things around (cant actually see anything though) Thanks!
