Need power supply suggestion for new GPU

Hey,

I recently bought an ATI HD 4350 for this Compaq PC:

After installing I noticed that the PC is not performing as it once did. It got really slow. I was told to get a new PSU. I've been looking at these ones:

and

Would these be compatible with my computer? Would I need adapters for my current hardware? I'm clueless when it comes to power supplies.

I appreciate all help given :D Thank you.

  1. the PSU you linked are better served as paper weights or fireworks for the 4th of July...you celebrate that in the UK right?

    the ATI 4350 uses as much power as a case fan and while upgrading to a quality PSU is always a good idea, I doubt its your issue.

    this would be a very good upgrade for you

  2. Hi ct1615,

    Thanks for the reply. I should have mentioned that I don't want to spend over £25 for a new PSU. I know its cheap but its being used for a media PC.

    I think the 4th of July is just an American celebration (When you guys got independence from the British).

    Any other suggestions?
  3. i was joking on the 4th july

    i would not go below this antec unit in price, anything else and you can endanger your hardware (its in your budget on scan)
