Rampage Formula restarting with powerful GPU

I have an ASUS Rampage Formula here which is doing something odd: It behaves fine with a low power graphics card that I have which doesn't require any PCI-Express power connectors, but with my GTX570 or my GTX295 it won't even post - keeps powering off after about a second and restarting a few seconds later.

It's not a PSU problem or a problem with the cards (verified with other equipment).

Any ideas what the problem could be?

Do you know where that option is?

I did - couldn't find it.

Uhm - my BIOS doesn't look like that. It's the old style blue BIOS.

I've got a feeling it's something else anyway - the board is behaving oddly even with the low power card sometimes. But I'd really like to get some idea what could cause that sort of behaviour for curiosity.
