Recently I have replaced my graphics card from HD 4200 to HD 7750.

Here's the specifications of my computer,
CPU: AMD Athlon II 645 Quad-Core ~3.1 Ghz
RAM: 6GB DDR3
Hard Drive: 1 TB
Power Supply: 230/320 Watt (Either one I can't recall exactly)

Anyway, the power supply is way below the wattage recommended by the manufacturer of the graphics card, which is 500 W. I've heard about the potential harms to the motherboard and want to replace the power supply as soon as possible.

I need help because there is a whole bunch of products on the Internet and I'm not sure which brand or what should I purchase that completely fit my computer. So, any advice?

Thank You in Advance.

P.S. Ever since I've upgraded my graphics card to HD 7750, my computer has windows update every time I turn my computer off. It is odd because I've never experienced this before. It occurred once in a while in the past, but now, it's like every day.

Again, Thank You.

Cheers, Kramiul

I've been digging through amazon and walmart for PSU. There is a variety of products and the price range for 500W is between $50-$60. So I guess the budget is about $50? I couldn't afford an expensive PSU and I'm looking for the one that is the best in terms of cost.
