Graphics card upgrade for a small factor PC?

I was just wondering if there was any GPU upgrades, any brand would do, btw, for my Acer Aspire AX3900 PC.

I currently have an ATI Radeon HD 5570, and my mother board is apparently a FIH57 model with a PCI Express slot. And my PSU is 400 watts I believe.

Thanks in advance.

You do have the proper expansion slot, however you have a very weak power supply, I'm actually surprised it even supports the 5570 according to the specs I found you only have a 220 watt psu. You're really going to need quite a bit more to be stable with a more powerful graphics card.

Ah well. Could you recommended a less power hungry card in the event I do upgrade my PSU, say, to 500 watts?

i gotta say i was really struggling to find a more powerfull psu that would fit in there.

i did find Scan.co.uk: FSP GROUP VR400A 400W Power Supply (PSU)

400 watt psu but i think your asking for alot from such a small machine.

i'd be mildly troubled by a larger psu in such a small space and would pretty much flag it as a fire hazard, my opinion ofc but i don't think the case has adequate cooling for anything larger.

if you search on "External Graphics cards", or similar, you will find plenty of info.

Thank you for that!! So the ATI Mobility series is an example of external GPU's right?

I haven't found the documentation for your system, but I expect that the AX3900 requires a low-profile graphics card. (That's normal for small form factor PCs.)

If so, the 5570 is about as good as it gets. High-powered low-profile cards aren't made.

ATI mobility chips are usually used in notebooks, although some may find their way into all-in-one desktops.
