Ok so i've got these parts at the moment -
Running a XFX AMD 6870 Black Edition
AMD Phenom II x4 965 BE (/w Coolermaster Hyper TX3 Evo)
16GB Corsair Vengeance DDR3 RAM
Coolermaster Scout with 4 x 120mm Fans
1TB Western Digital Caviar Green SATA HDD
ASUS M4A785TD-V EVO
Someone please help, in the past i've always used cheapo PSU's and never really encountered too many power issues? But this has been in less hungry systems, and ATM i'm stuck, all I need is a psu to get things up and running. I don't realistically want to be spending more than £50 on a PSU if possible, any suggestions?
The 6870 needs two PCIe connectors, which the CIT '650W' unit doesn't have.
Shows a system using an i7-920 (roughly as power hungry as a Phenom II X4) and an XFX 6870 BE drawing 322W at the wall under Furmark (unrealistic load).
10-20% can be taken off this number to get an idea of what the system actually needs in terms of power supply unit.
