    Thumbs up Which PSU would best fit my HP system

    I have an HP m7580n

    Basically that's

    CPU AMD Athlon 64 X@ 4600+
    Motherboard ASUS A8M2N-LA (HP name: Nodus-GL8E)
    Ram 2 gb Hynix PC2-4200 (2x1 gb)
    Storage SeaGate 320 gb 7200rpm Serial ATA

    with PSU Bestec 300 Watt single fan

    I found a shop that's selling a Palit 8800GT 512mb PCI-E for $239.99 canadian, I just missed out on the $199 sale.

    Now with my current PSU I can't maintain that graphics card. I was told I need at least a 500w one. So I went online, ghosted many forums and checked prices. Ideally I want something between $70-$90. Which lead me to these 4 PSU's at these retailers.

    1) OCZ 500W StealthXStream SLI (OCZ500SXS) #4727 $62.00 (Can) shipping unkown
    A-Power.com - Buy OCZ 500W StealthXStream SLI (OCZ500SXS.. - Canada

    This seemed to be a good choice for it's price and I can get the 600W for $89, but I'd rather not spend that much on the PSU. I think has 4 12V rails at unknown amps, but i`m not too sure. Has 2 PCI-E cables.

    2) Rosewill RP600V2-S-SL 600W SLI Ready-ATX12V V2.01 Power Supply 115/230 V CSA,UL,TUV,FCC $64.99 (US) 8.99 shipping
    Newegg.com - Rosewill RP600V2-S-SL 600W SLI Ready-ATX12V V2.01 Power Supply 115/230 V CSA,UL,TUV,FCC - Retail

    I was hesitant about this brand because I never heard of it, but with some research I've heard rumors where they're rebranded products, some claim to have OCZ's that look just like it, and others claim that its a brand that newegg owns. Has 2 12V rails at 19 amps. Has 0 PCI-E cables.


    3) Rosewill RP550 ATX V1.3/ EPS12V 550W Power Supply 115/230 V CSA, CB, TUV, FCC, UL $54.99 (US) 8.99 shipping
    Newegg.com - Rosewill RP550 ATX V1.3/ EPS12V 550W Power Supply 115/230 V CSA, CB, TUV, FCC, UL - Retail

    Now this is obviously a little lower in Watts but it comes with different amount of wires with a cheaper price. Has 1 12V rail at 35 amps. Has 0 PCI-E cables.


    4) Antec NeoPower 550 ATX12V 550W Power Supply 100 - 240 V UL, CUL, TUV, CE, FCC, CCC, CB, C-tick $99.00 ( 69.99 after mail in rebate) (US)
    Newegg.com - Antec NeoPower 550 ATX12V 550W Power Supply 100 - 240 V UL, CUL, TUV, CE, FCC, CCC, CB, C-tick - Retail

    This is obviously the most expensive, probably due to the brand name. It does have a mail in rebate. It has 3 12V rails at 18 amps. Has 2 PCI-E cables.

    ----------------------------------------------------------------------------

    Conclusion:
    In addition to that information it`s important to me that the first provider is in Canada, so no international shipping. Now while the shipping and handling is cheap, I`ve ordered a Zune from the US only to have been billed $50 3 months later for some tariffs or cross border tax or something.

    I don`t know much at all about PSU`s, this is only about one nights research. I`m curious about what would be the best match with HP m7580n, reliability, future use, and easy to install (never put in an PSU).

    I open to all comments, Ideas, Opinions and suggestions. I hope you guys can help and thank you in advance.

    One of the favourite power supplies on this forum is Corsair, while you might get a better bang for buck on other brands....you can't go wrong buying one (Corsair).
    2nd computer gigabyte P965ds3p, 7770 E2140@2.9ghz, corsair HX520 6 years stable, replaced now with E8400@3.9ghz and will overclock more when I'm bored.

    K thanks, I decided on

    Corsair VX550W 550W ATX 12V 41A 24PIN ATX Power Supply Active PFC 120MM Fan

    I found a better deal for the 8800GT but it's made by galaxy. How good is a galaxy 8800GT 512mb to a Palit 8800Gt 512mb?

    Re: Which PSU would best fit my HP system

    galaxy are fine, palit are really a budget brand anyway.

    You would get away with the VX 450w if you wanted to save a little money.

    If you have a little more to spend the 520w HX modular is a very nice psu.
