What GPU do you reckon I can get away with an a SFF 250w PSU with 16A on the 12v rail

Going in a Biostar IDEQ 330N so must be single slot. Also as title it has a SFF 250w PSU with 16A on the 12v rail. What do you reckon is the beefiest card I can sensibly get away with? Would a 7900GT be my limit?

Rest of the specs are:

Opty 165
1x HD
1x DVD-RW.

That is what I am using in my iDEQ, along with a X2 3800+ and 2Gb of ram. Works a treat!

Is that a 250w PSU as well then fella? Just out of interest does a Zalman 900cu fit in the space, and if so would a 512MB X1800XT be too much for the poor wee PSU?

Guys will an X1950 PRO definately run on this 16A PSU? I'm a it nervous about stressing it and am wondering whether I should just sell the thing for what I bought it and buy something a bit beefier.

SSF PSUs are in general built like rocks, and are absolutly fantastic.

Yeah but 16A on the 12v rail... that's surely pushing it for cards like the X1950 Pro and 7900GT etc.

I don't think it will work. Sapphire states 30A on the 12v rails. I've seen people running a 1950pro's with 12v rails down in the low 20's, but 16A? Doubt it mate.

Yeah to be honest think im goiong to sell the IDEQ and just build a midi-tower with a proper PSU instead. Then I don't have to arse around with a single-slot GPU either and can use the 512MB X1800XT I got for £60.

Can't the PSU be upgraded?

PSU and Motherboard are the 2 most important components in a system, I wouldn't skimp on either.

Not worth the hassle of upgrading it... it's a proprietry micro-ATX PSU. May as well just sell the thing for what it cost me.
