GeForce GTX 460

So I just installed my GIGABYTE GV-N460OC-1GI GeForce GTX 460 on Monday and everything is working fine except now when I Shutdown or go into Standby I can't turn my computer back on. When I push the power button I get no fans or anything. The light on the motherboard stays on though so I know it's getting power.

The only way I can get it to turn back on is to pull the power plug from the power supply and wait 1 minute, then plug it back in and it boots right up. If I don't wait 1 minute it won't turn back on.

I'm using a power supply/mobo that I got back in 7/27/2006.
Mobo: ASUS P5W DH DELUXE
Power Supply: OCZ GameXStream OCZ700GXSSLI 700W

Any ideas what is going on?

  1. Your PSU, how old?
    I know it's a good brand, but looking at your case, i think this is PSU problem...

    make sure all the cables are properly connected, especially the Power button on your case...
  2. I got the power supply back in 7/2006 but I think I might have found the problem. The GTX 460 requires (Minimum recommended power supply with +12 Volt current rating of 24 Amps.)
    My power supply is only 12 volt 18 Amps.

    Anyone heard of having too low of amps making so once you shutoff your computer you have to unplug the power for 1 minute before the power button will work again?
    What's weird is once it's on I can play starcraft 2 all day with no problems. It's just when I shutdown or go into standby it won't start back up.

    that's your PSU, right?

    If yes, take a look at this:
    http://www.ocztechnology.com/resources/drivers/GameXstream_700W_chart.jpg

    Your PSU has 4x 12V rails, each rails has 18A. That's 72A total. More than enough to run GTX460...
  4. Windows 7? Or Windows Vista? Try enabling wake on USB/Keyboard in BIOS.
  5. Yeah that is my PSU. Oh so they add together and that is my total amperes? Well last night I ordered this new PSU http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005
    So we will see if that does the trick.

    Alikum thanks for the reply. I'm running Vista 64 but I will check the BIOS to make sure wake on USB/Keyboard is enabled but I can't even turn it on using the power button after I shut it down so I don't think it is that.
  6. @digvijaysingh, ask your questions in your own thread.
  7. Just an update FYI I got my new power supply and the problem is fixed. So it seems it was the power supply.
