Power supply issue? New Radeon5850's fan runs at full speed and PC doesn't boot

I recently bought a new ASUS EAH5850 graphics board. I installed it a custom PC which had an ASUS p5n-e SLI mobo along with a 500w Thermaltake W0093RU power supply.

"I had this exact same problem this weekend. For me it was the power from my 1000w Powersupply.
The 5850 has qty2 6pin connectors, in the instructions it said I could use either 1 or 2 connectors. I only used 1 and figured I'd save a cable, well bad mistake because the card wouldn't post and I spent an hour trying to figure out why. I added the second power connector and it fired up right away. Hope this helps someone"

"With many cards, the fan will run at full speed until the driver loads. If some problem prevents the driver from loading, e.g. the system does not boot successfully, the fan will continue to run at full speed. I suspect the fan running at full speed is a symptom of another boot problem.

Since it only happens with cold boots, could be related to hard drives and/or optical drives spinning up during power-on. You might look into staggering the drive startup (google it) or test with fewer drives to see if that's the problem."
