What Power Supply are you guys using for 4870 in Crossfire?

ATI site says
ATI Radeon™ HD 4830 System Requirements
* 450 Watt or greater power supply with 75 Watt 6-pin PCI Express® power connector recommended
(550 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode)

I just fried a mobo using a 680W PSU with Crossfire last week, so I know that isn't true.
On my new Asus mobo, the manual says to use a 1000W PSU.

I'm considering getting this PSU:
Rosewill RX950-S-B 950W
80Plus Certified,ATX 12V v2.2 & EPS 12V v2.91 SLI 8800Ultra SLI CrossFire Ready Active PFC PFC Power Supply
