You've either got to buy a better PSU or a cheap graphics card that doesn't use a PCIe power connector. A 4890 is way overkill for a non gaming rig.
I would only be getting the 4890 because i know where i can get a 4890 and 4gb of xms2 with custom heatsinks for £60.
really cheap, and actually very very good psu

You've had some good advice here. Mostly that you should use onboard graphics. Using two **** psu's at once will be interesting, because they'll disagree on what 12V is and probably on what 0V is. That'll damage things at an unknown rate.
If you value any of the hardware, don't plug it together. I'd chose whichever FSP looks least knackered and use onboard graphics (on the basis that the graphics card is the most valuable thing there).
If you just don't want to listen to reason, then plug it all together and trust to luck. You'll get something which is both slow and unreliable, but it probably wont catch fire.
Don't worry guys, using the 350w Psu on a core 2 duo 2.66 with 4gb ddr3 and probably a radeon hd 5450... That would be alright right?
im using a q6600, 4gb ddr2 and a gtx460 (overclocked no less) on a 2007 dell 350w psu
i really ought to replace it after 5 years of abuse.
