Hey guys and gals,
Just upgrading my GPU from an nVidia GT220m to a XFX HD 6950 1GB and because of which I need a new PSU. At the moment I am using a 500W one but some calculators are recommending at least 550W. I want to spend as little as possible obviously so below £40 or perhaps £50 would be ideal. Also I need
2 SATA connections - one for the hard drive, one for the CD drive
2 6pin PCIe connections for the HD 6950
24pin connection for the mobo
and a couple of 4pin peripheral connections for extra fans etc.
yeah it always comes down to cash--they both look alright--dont see how long a guarantee or warranty you get--the corsair has a 3 year warranty which is pretty good considering its their lower range psu
The 750 watt unit with it's dual rails at 16 and 18 amps is no more powerful than a Corsair 500 watt and only has a single six pin connector, the 650 is probably worse , didn't bother to look.
mcnumpty's reccomendation would be your best bet.
PS: you won't find the Powercool name on the 80+ list
