What PSU do I need for a Nvidia geforce GTX 560?

Title says it all, What PSU do I need for a Nvidia geforce GTX 560? I already figured I need atleast 450W for a minimum, So I'm getting a 500-550W PSU just to be safe. But I wonder if theres anything I'm missing here that's important before buying a new PSU. Do I need an ATX or an ATXV12? Do I need 80+ bronze certification or none? Do I need dual or quad v12 rails? Etcetera.

Oh and I'm not planning on overclocking.

    Get this one:

    The rails, the exact ATX spec, Bronze cert, etc. are all down in the noise on a system like this.
  2. Choose a PSU that has atleast 500W power supply and make sure that it has two-6 pin connectors.
    Corsair CX500 is perfect for GTX 560.

    ok, you seem to know that you need a 450+ watt and that's reasonable as long as you don't have a power hungry OC'd sandy bridge-E or FX83xx rig with water cooling 100 case fans and whatnot. oh and likely no disco ball.

    a lower watt PSU like that will usually be single 12 volt. there are some that have multi rails but for a few reasons i wouldn't touch them with a barge pole. so get a single 12 volt rail. the biggest question about a 12volt rail is; does the amperage supply atleast 80% of the PSU's rated output? (ie 550 watt PSU ought to have atleast [550*.8= 440/12] 36+ amps)

    the ATX and ATXv2 is for the 12 volts for the cpu connection. don't worry about that - standard is v2 for the extra power most all cpus need anymore.

    when it comes to bronze, silver. gold or platinum - the higher the efficiency the better, more so with higher wattage units. but that does not necessarily mean its a quality unit. i have read reviews of "gold rated units" that were tested for certification at lower temperatures that made the unit look great (~30c) but once they were put in a "hot box" (~50c) not only did it fail in efficiency but the unit shut down before being able to supply its "rated" load. ie 750 watts.

    there are a few reputable brands like antec, seasonic, and XFX. there are some brands that have good series (or models) like the rosewell fortress or capstones, coolermaster V or silient pro series.

    the question is what is your budget?

    this is an outstanding PSU:
    Rosewill FORTRESS-550 550W 80 PLUS PLATINUM $69.99
    Save: $70.00 (50%)
    $49.99 after $20.00 rebate card

    the price of that is just too hard to pass up

    Thanks, but I think the Corsair CX500 will be perfect for me, I haven't got a beast pc with a water cooler and everything. Also the CX500 fits better into my budget. Thanks for all the help though!
