Recommend me a PSU please

Hello guys, First of all... Happy New Year!! : ))

I just found this great website while looking for PSU related answers in google.

I really hope you can help me with my issue. As I tried googling but couldnt find an answer that I could undestand. Im sorry if Im asking a noob question, Im not really a computer hardware savy.


My Desktop computer is HP a6512p standard set from HP. Now I bought a graphic card ATi Radeon Saphire HD 5770

and the video card is not compatible to my power supply. I was going to buy a PSU with 450watts but then I've read somewhere that they are not standard size and chances are that it wont fit in my case.

Well the case is just the standard Mid Size ATX case as its shown on HP website here.

So I need a PSU that meet these requirements from Radeon for the Video Card and also fits my case.

I found some PSU-s on ebay, for example this one - in price range of $30 - 50, I was wondering if that could work well with my PC, as the price looks good to me and also its 600Watts so its even better right?

If the graphics card needs 450w I would need to buy something with higher watts so that energy will be enough for all other components too, is it so? Sorry a real noob here : ))

Thank you for your time and help!
Regards,
Archie

More about recommend please
  1. Corsair cx 500w.
  2. You will find that there is no real price drop in sizes below 650 watts .... among quality units anyway, so I don't bother w/ anything smaller these days. Also remeber that a PSU is most efficient at 50% load.

    At $60, this one's $5 more than the 550 watter.

    It's made by Seasonic and gets a 9.5 performance rating from jonnyguru

    The Corsair TX650 is also made by Seasonic as is the Cx400, and the Corsair TX650 V2 also gets a 9.5 but they are significantly higher costly ...the rest of the CX series is made by Channelwell.
  3. Wow, thats a quick response. Thank you guys, appreciate your input.

    I like XFX Core Edition PRO650W, its a little bit more expensive than I was going for, but not higher than $100 so I could go for that. One question though, do you think it will fit in my case or will I have to Buy a new PC Case too ?

    Thank you

    For a system using a single Radeon HD 5770 graphics card AMD specifies a minimum of a 450 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 22 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

    Judging by the image of the HP a6512p it's a standard ATX12V (PS2) form factor power supply unit.



    The following power supplies all have a +12 Volt continuous current rating of 28 Amps or greater and have one or more PCI Express supplementary power connectors:

  5. Video card doesn't need 450 watts , that's the manufacturers reccomendation for the entire system with said card.
    A CX430 would be more than enough for your specs ( HP a6512p ) and a 5770

  6. ^+1 I agree with the guys = CORSAIR Builder Series CX430 V2
