Power supply size

[Craighep]

Hello,
I recently bought an all in one z3731 pc from acer. it has on board graphics (not good enough...) so i wanted to stick a grpahics card in the pci e slot i have. however, i learnt that i need a better power supply seeing its only 200w :/
except i have a problem that my psu size is rather odd, 20.5cm depth, 9.5cm wide, and 6cm high. cant find one that fits anywhere.

Your power supply is actually 220w...the best GPU you can get for that power supply is the Radeon 5570. It only consumes 50w at load. I had a similar power supply and I ran that video card without issues.
