I'm concern about the AMP. I think the GPU needs 12v and 24 amp:

DYNEX From what i've gathered..

Dynex 520w ATX specs [import voltage 110V; output voltage +12V1DC; max load 18.0A; min load 1.0A; power peak 520w; regulation +-5%; ripple 120mV; noise200mV; power good signal 100-500mS; power fail signal 1mS Min; hold-up time 16mS Min

    Hi - The 7850 should work with that PSU, but it's not a gimme. That PSU
    is a 420w unit the 520 is peak (if you look at the sticker on the PSU it will
    state 420w max), it has two +12v rails, one at 18a and one at 16a. You should
    be able to run the 7850 if the PSU has the PCI-E connector, it wasn't listed
    in the not very informative specs.

    I've visited a couple other forums with comments on that PSU, seems to
    have a lot "computer randomly shuts down" complaints.

    I suggest, if you can afford to do so, purch another PSU. A quality 450w unit will
    run a system with a 7850. If you live in the US, there's all kinds of good
    deals occurring now. Stay with quality brands: Seasonic, XFX, PC P & C, Antec,
    Rosewill Capstone/Fortress series, most Corsair, most Silverstone, & a few others.

    I think it does..

    There are 4 SATA connections (3 on one line +1 on a line with a Molex connection)
    There are 3 Molex Connections (2 on one line +1 on a line with a SATA)
    There are 2 PCI express connections (on the same line, also one of the PCI also has an 8 pin adapter which makes 8 pin cards compatible)
    There are 1 Motherboard 20/24Pin and 2 Four pin (or one 8) pin CPU connection
    There are 1 Floppy Drive connection (on the Molex line)
    I forgetting some I believe!

    Base on the REVIEWS on AMAZON...
    http://www.amazon.com/Dynex-520-Watt-Power-Supply/dp/B0067SJC80/ref=sr_1_1?s=pc&ie=UTF8&qid=1372804659&sr=1-1&keywords=dynex+520w

    So should i buy it? and will it fit on my ACER DEsktop?

    Antec is a much better unit.

    If you are not locked in to Amazon, there are better deals to be had on quality PSU's.

    It is a legitimate 500w unit, and has 34a on the +12v rails.

    If you are considering that Antec @ $52, please look at this:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817207013 XFX pro 550 nets to $40
    after promo(prom expires 7/4) & mir.

    Oh wow i didn't see that... thanks so much.. your good i'm such a noob ;)

    Last concern what does this guy means
    " Note though that this only has a 20 pin power connector so it cannot be used on DDR2 or DDR3 systems which require a 24 pin power connector. "

    my setup is ddr3 8gb ram i believe... the gpu is ddr5

    Not to be concerned - the gpu ram doesn't interfere with the system ram.
    The motherboard power pin (20/24) is actually a 20 +4, you use the 20 if
    your mothboard has 20 and use the other4 (24 tot) if your mobo has a
    24pin socket.

    The Antec and the XFX both have 20/24 power pin connectors.
  8. thanks :)
