Benchmark / test to ensure video card stability with small power supply?

[Kremlar]

I'm putting together a system, and I'd like to use a smaller Micro ATX case with a 270W power supply.

The system is a 3.2 Ghz Pentium D, 2GB RAM, DVD-RW drive, an 80GB hard disk, and an nVidia Geforce 7600GS PCIe video card with 256MB.

The system seems to be running well, but I'd like to really burn it in to be sure the 270W power supply will be enough for that video card.

Can anyone offer any kind of freely downloadable recommendations?

Thanks!!

Rthdribl_1_2 is a great program, fairly easy to download and really push your card to the limits.

I'm giving that a try.

Thanks!
