Power requirements - Leadtek 6600 GT TDH

[deadlok]

I bought a brand new Leadtek 6600 GT TDH on AGP. After i installed it. i made some tests and it worked fine. However, after some time playing heavy load games (Splinter Cell 3), some short beeping sounds came from inside the case randomly, but not from the internal speaker, and ceased when the heavy load on video card stopped. They were somehow like the sounds from a hard drive failing to spin. I never had this issue before, with the old card Leadtek 5200 FX, so i suspect the hard drive has power issues due to the new videocard power consumption. The computer does not crash, or give errors, but that beeping seems like ill news for me.

My system specs are :
Celeron 2 GHz
2x256 Kingmax DDR TinyBGA
Gigabyte Titan series MB
1x Maxtor SATA HDD 80GB
1x DVD ROM
1x ASUS DVD RW
370 W Enermax Noisetaker P series power supply (18A on each +12V rail)

also, the HDD temperature now goes between 49-53 C, and the SMART readings show the drive is ok.

Can you please tell me if the power supply is good enough to support this configuration ? And if it's ok, what can the beeping sound signify ? Thank you.

Thanks a lot.

Do you have the power connector on the card plugged in to it's own line?

Are you possibly hearing the card's fan speed up under load?

The beeping could be one of your BIOS alarms such as CPU temp or a low voltage alarm.

Yep, the video card has it's own 12V line, not shared with anything else.
The series of short beeping sounds (it sounds actually like a low,short "bep") appear mostly immediately after i exit any high-demanding game. The number of "beps" is from 1 to 6, and it doesn't seem to come from the PC speaker.

Can you unplug your 2 optical drives to free up some power and see if that makes any difference?
