8800GTX BEEP

[Slotback]

Hey

My bro has a ASUS P5K DELUXE and an 8800GTX powered by a Corsair HX620. He tried it with a Thermaltake PSU too. At the moment the computer powers OFF, it lets out a single, loud, high pitched beep, that lasts for about a second. It is definitely the videocard. If we turn the computer on, then restart it (as opposes to shutdown), no beep occurs. It's unrelated to anything to do with normal POST beep. This is from the videocard and happens when the rig is powered down.

We tried taking out the dual PCI-E connectors, the videocard makes the same beep constantly. So I presume it is a power issue. Strange, because it is 100% stable in applications such as FURMARK. I was thinking that it was just a small querk with the P5K where there was enough charge left over to cause it to beep for a second.

Any ideas?

==============================

The Geforce 8800 family uses a internal hardware power sensing technology which will warn the user if the Geforce 8800GTS/GTX graphics card is not receiving sufficient external power from the PC power supply. In some cases, a power supply may cut off power to the graphics card before the PC shuts down resulting in a short beeping sound from the graphics card. The power sensing technology is designed to ensure a graphics card receives sufficient power to prevent possible damage to the graphics card and therefore can not be disabled.

Its probably the PSU .. but does not mean its defective, just a glitch at shutdown
