Just recently installed a new 400w power supply unit onto my old Dell 8300 and I am awaiting an AGP XFX Radeon HD 4650 graphics card and I'm concerned that my new PSU won't support the graphics card, anyone have any opinions on the matter?
Should be no problem
I have a 1gb Sapphire 4650 fan cooled low profile in a Dell Optiplex with
a Dell 280 watt psu.
I have even mildly overclocked it and ran PCMark and 3dMark03 with no
The HD 4000 series is famous for low power usage.
I have a Pentium D 3.4ghz and I run BioShock 2 at highest settings at 1920x1080 res with no lag.
As long as your psu is a reasonable name brand you should be fine.
Also as long as your not running 2 hds,2 optical drives and multiple slot cards you should be fine also.
HD 4650 uses almost nothing. I have one running on an old machine with a 300W power supply and have experienced no problems whatsoever. I've heard of people running the 4650 on a 275W or even 250W PSU as well, though the latter case may be pushing it a bit, depending on the rest of the system.
