Hi guys. Getting a graphics card update from my Radeon HD 6570 1 GB DDR3.

Anyways, my PSU as you can see is really under-par. I was wondering which was the most powerful graphics card I could possibly run without a chance of overload.

I have an eye on a 7750 atm.

Specs:

AMD FX-4100
HD RADEON 6570 1 GB DDR3
7200 RPM SATA II Hardrive
8 GB DDR3 1333 RAM
GA-M68MT-S2 Motherboard (rev 3.1) BIOS Update: 20th Feb 2012

It's definitely not a spectacular PSU...and that's being nice. I would sriously consider putting down $20-25 for a Corsair CX430 (MIR). The CX430 has 28A on the 12V rail and would handle up to an HD6850 without any issues. You Winpower with 20A....is electrically sufficient to handle the HD7750. What is the specific model number?

I would replace the PSU, as Rugger suggested, I would consider that thing a liability more than anything.

If you have the budget, a new PSU will free you up to get a graphics card to fit your needs; a good 500W PSU is enough to run 7870, you don't need anything massive. (Be sure to check and make sure the combo you choose will work before buying).

If your budget is limited, or you want to keep it small but are flexible, consider replacing the PSU with the CX430 as he suggested (or something larger now, and upgrade GPU later). A bad PSU can be dangerous to the rest of your PC, and can cause other parts to fail when it blows, or just slowly damage them over time by providing out-of-spec voltages.

If it really is a liability....

I had my eye on this one.

Worth the price? I want to spend as little as possible.

The Corexstream doesn't have a review track record. In that price range I'd go for the XFX Core 450W: http://www.scan.co.uk/products/450w-xfx-pro-core-editio... It's 80+ Bronze, has two more years of warranty and is made by Seasonic...great value for the money. It only has slightly less power on the 12V rail than the OCZ (408W vs 444W) but it has the same amount of PCIe power connectors and is more than sufficient for your build.
