Got a Opteron 170, X1900XTX, X1900XTcrossfire, DFI RDX200, 2gig RAM, Xfi, 2 Raptors and 2 other Hard drives, 1 optical drive system. Powered at the moment by a 520W OCZ PSU. I can Fold all day long, but system crashes when I try to run 3dmark01. Need a new PSU?
 
probably, folding to my knowledge doesn't use large graphics power, while 3d mark is a graphics stress-test and as such large amounts of power would have been drawn from the psu

Got one here in another crossfire system - what about the FSP Epsilon 700 FX700-GLN - opinions?

The problem with that is the 12v is split into 4 rails...also, the 3.3 and 5v are a tad low.
 
I suppose I could test the Liberty I have here over Easter and see if it works. Afterall probably too late to get anything before Easter now anyway.

Would love a PC Power and Cooling Turbo Cool 1kW, but thats crazy money!

Aside from being overkill.
 
Maybe, maybe not - would future proof you for a bit - add a few more drives, one of these physx cards and some uber cooling. And you wouldnt have to worry about lack of power, but 350 quid (ex delivery) is a bit steep!

Thats more than some entire systems. Also you had an Enermax Liberty lying around...

5v/30A or 3.3v/36A is not low. Especially as nothing with a serious load uses either rails. And there is nothing wrong with 4 rails. It's better than two, besides they all feed from the same source. 4 rails have a lot less chance of reaching 240VA on any one rail and tripping the OCL.

I see your point, but the individual 12v are only ~14A each.
 
Yeah the FSP is a great PSU by all accounts, especially for high end SLI. I'm using one after having problems with my OCZ 600W Powerstream and SLI and since switching it's performed flawlessly.
