PSU/GPU Upgrade

I've recently gotten a new pc, and while it runs most of my games fairly well, it falls short in some places. I'm looking to upgrade the PSU/GPU since it's running off the nvidia 9100 chipset, which isn't built for gaming.

Here is my pc

Can someone recommend me a decent 600W+ PSU(maybe i dont need one this big, not to sure) that I can pick up for about 60-70$(before shipping).

I would also like some suggestions for a GPU to match, 100-150$ range.

Main uses will be gaming(WoW) on mid-high end settings, fraps, live streaming, rendering.
Not sure what resolution range I could get for that price, but my monitors max is 1920x1080.

Advice is needed! :)

Forgot to mention, I dont plan on Crossfiring or upgrading any other parts in the near future, nor do I play extremely graphic intense games(like crisis), so any mid ranged card should be good enough.

  1. This article from Tom's seems to be the place to look:,review-31866-3.html

    The Radeon HD 5770 seems about to be about your price range.

    The official recommended power requirements for that card are as follows:

    450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode)

    This applies to the whole system not just the card.

    So realistically, if you don't plan to Crossfire in the future you could get away with a good 500-550W PSU. Corsair, Seasonic and the newer Antec models are the recommended brands.

    Off the top of my head, the Corsair 550VX would suit your needs fine, with some headroom to spare.

    Hope this helps!

    The 5770 + Corsair 550W does seem the best bet. However, do check whether the psu is compatible with you case.
  3. I'm not sure if the 550w is compatible with my case or not, how can I find out?


    would this be the right card?
  4. Check dimensions of current power supply in your case, then compare to dimensions of psu listed on web site.
  5. Cant seem to find the dimensions, really wish I knew more about hardware. The PSU I have now is a Bestec ATX-250-12z Rev D7R, If someone could kindly find out for me I'd appreciate it.
  6. Coolmaster realpower SLI550w comes with a power meter as well! Its not bad either... Mine works perfectly fine with a 5850, its rated 80plus bronze and its around $60-80. Perfect fit.
  7. You have a micro atx psu, therefore only a micro atx form factor psu will be able to fit into your case. Here's a replacement (upgrade) of not so great quality, but you have to take what you can find. Athena Power AP-MP4ATX47FE 470W MicroATX / SFX12V / EPS12V / ATX V2.2 SLI Ready CrossFire Ready eMachines, HP Upgrades/Replacement Power Supply found on for about $60 shipped.
  8. a friend recommended me this

    Antec BP550 Plus 550W Continuous Power the dimensions are 3.4" x 5.9" x 6.1"

    what do you guys think, will this work? or do I need the one below.

    This is the only micro atx on newegg i can find that is 550w

    Athena Power AP-MP4ATX55FEP8 550W MicroATX dimensions 5" x 2.5" x 5.12"

    from what I've read, most standard atx psu's will fit into the hp cases, so I shouldn't need the micro atx versions correct?

    would this be the right card?

    Get this one instead

    For the psu, do you have the manual for your current psu? It should have the psu's dimensions. If not, you'l need to remove the psu from the chassis & then check its dimensions.
  10. Technical Specs: for my current psu

    * ATX Form factor
    * 6.00" Wide X 3.25" Tall X 5.5 " Deep
  11. Does the psu fit snugly into the case? Or does it have spare room within its compartment? It would be best if you knew the dimensions of your case's psu compartment (assuming there is one). Obviously, then it would be easy to find a psu that would match those dimensions.
  12. The antec BP 550 fit in just right, thanks for the help :D
