Hi

I currently have A Dell Dimension E520 which has a PSU of just 305W and an PSU that provide 28 amperes on the line of +12v and i would to know if that HD4850 works in this system.

Thanks

No it will not. You need more wattage.

That doesn't sound like enough.

no way. ur psu is too low W. u need to upgrade it, make sure the motherboard is pci x16 too

Oh ok! tks guys and sorry for the double post!

A 4850 is said to use approximately 225-250w fully loaded.

Not likely. It only has one 6 pin power connector. The PCI-E slot is rated to provide 75W, and the 6 pin is also rated for 75W. Therefore, the most it could draw is 150W.

You only have 22amps, not 28.



Here's a 500w @ 35amp that's the same as a Dell recommended replacement, but cheaper, or get any ATX one you see fit:

hmm, 28amps and 12 volts makes 336 watts, thats quite well for a 305W PSU..... or do you have 2 separate units?

Anyhow I think it might work, for a while anyways P

edit:kpo6969 beat me to it.....
