  1. I am building a brand new computer yet again.

    Cpu - AMD Athlon 64 X2 5000+ Brisbane 2.6GHz Socket AM2 65W Dual-Core Black

    Mobo - BIOSTAR TF560 A2+ AM2+/AM2 NVIDIA nForce 560 MCP

    Memory - G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)

    Video Card - HIS Hightech Radeon HD 2600XT 512MB 128-bit

    Case - 12 bay ATX

    Power Supply -

    I am very confused on which power supply to buy. I understand the stuff i will be running needs a good one. I heard FSP was good so im thinking of trying this.

    the question is, will it be able to run the things i will be using ?
    If not, what would be the cheap and good power supply to run the things i will buy.
    any suggestion is appreciated.

    Also, is there anything wrong w/ my selection ? such as mobo or etc.
    any suggestion is appreciated.

    thank you~

    Meh, $36.99 isn't bad for what it is. I believe FSP makes a solid PSU in that I don't feel you are putting your PC at risk by using something they've manufactured. However, that PSU has no PFC and has a measly 12ms hold up time. With 36A on the 12v rail you should be fine to power those components.

    That said, I would take a look at something such as the following if your budget will allow it:

    I am just looking for a cheap PSU. I dont plan to Over-clock or anything like that.
    I just want to make sure it will run those amd's/ati radeon 2600xt without a problem.
    maybe the max i could go is $50.
    Zeno, thanks you your suggestion =]

    Okay, well, here: OCZ500SXS. It's got active PFC, 80% efficient, 36A on the 12v rail, 500w output, all the connectors you'll need, and it's not a crappy manufacturer if that counts for anything. Only $39.99 after rebate, hard to beat that, believe me.

    I purchased this a few weeks ago, and it works great. It's actually quieter than the rest of the fans in my computer, so you can leave it on the high setting.

    But since you have a ceiling of $50, just get that cheap one you posted, it should be fine. Just don't be surprised if you end up having to RMA it.

    I'm not much of a fan of MIR's either, but hey, it still fits the bill.

    Don't buy that Thermaltake PSU. For starters, it's only got a single 12v rail with 18A (ha), it has no PFC and is only 65% efficient. Even if you didn't care about the quality of the PSU, that one probably wouldn't even have enough juice to power your components. Spare yourself the restocking fees ;).

    oh >__<
    -goes back to looking-
    im trying to find one without the mail and rebate and still under $50 but if i cant see any good one then, alright. i'll go with yours.
    Also i dont "NEED" to have a psu with Pci-E 16 connector if i use (HIS Hightech Radeon HD 2600XT 512MB 128-bit right ?

    Despite the fact that it lacks PFC, it's not bad for the price. If you really can't deal with a MIR, that would be a more preferable alternative to some of the others you have chosen.

    First, I'd suggest this as a better video card choice.
    Also, this PSU is an excellent choice, since the SilverStone one you linked to will come up to about the same price along with the shipping charges. It provides more power on the +12V rails (about 34A vs the 29A on the SilverStone) and has excellent efficiency.
