Hello ...
After 5 years the time has come for a mini-upgrade.

The setup i intend:
C2D E8400
P5Q
4x2GB DDR2 PC8500
ATI 4870
2x80GB SATA Raid0

Because finances are very tight, how many watts and above to begin to wanting? Also from experience what you recommend?

Corsair 550w ... may be made and Pc Power & Cooling 500w.

I feel that of fewer watts. I think that 700W or above is what would be required.

If you have aspirations of doing Crossfire in the future, even the 450W of Corsair is enough. A litheia will put 8 gig memory or typographical error.

I would evade in Raid larger discs, however, and would be happy with 4GB memory ram or less. A quality 450ri - 500ri is enough for the system. (such as Corsair mentioned)

If you say your finances are tight, how is this possible!!!

When you want to do overclock I am not quite sure if the 450 is enough room flat. In default, speeds certainly suffice. Also certainly the >700 is an exaggeration. I would advice the Corsair 550.

I already have a RAID0 hard disk. The 8GB will be combined with Vista and a music production programs.

When I say tight finances means costing around with a heavy heart for psu. No direct interest to crossfire. Unless the 4870 proved potatoes for games! The overclock will be basically in CPU / RAM.

The two below will fill in perfectly, you do not need greater power. Also see their reports here,

Well those are Corsair 550W CMPSU-550VXEU and ENERMAX EPR525AWT PRO82 + 525W. Seem to be perfect. Will have a look at the reports. Thank you for that recommendation.
