While the 5850 and 6870 recommended a 500 watt power supply, I recently upgraded from a 4850 to a Sapphire HD 6870. I can confirm that my Corsair VX 450 watt runs it fine, even under the stress of games.
The corsair range are top quality PSU so don't just think a random cheap 450 watt will run these products, I would ALWAYS recommend paying a good amount for a good PSU, they are critical to the safety of your system. While you may spend a little more up front, you can guarantee they will last you years, not months. Infact the Corsair VX450W comes with a 5 year guarantee, so yes this will last and perform well.
From my own experience, I have had one cheap PSU die on me, while it did not take out any of my other components i feel that is only because i caught it in time. I was shocked to discover a very strong chemical smell coming from my PSU and immediately turned off the power. Considering how strong the chemical smell was, I am still left shocked. No more cheap PSU for me, please don't make the same mistake.
I can highly recommend the Corsair VX450W for the 5850, 6850 and 6870. It will run them with ease.

Thanks for confirming that , I have a Corsair VX450W and I was planning on upgrading my Geforce 9600GT to a HD6870; I had doubts on whether the VX450W would be able to make the cut , but you've made it clear.
Here's my config , I'd like your opinion on if the VX450W will be enough :
Intel Core2Quad Q6600
ABIT IP-35E Motherboard
1x250 GB , 1x200 GB SATA HDD
Sony DVD-RW drive
6GB DDR2 800 RAM
Easily. Stats show the following average power consumption.
Geforce 9600GT
197 wats loaded
120 wats idle
6870
161 wats loaded
28 wats idle

Thanks , I had no idea the 9600GT was a wicked power hog. But it was a great card; sad to see it go since I've now decided to try full hd gaming.
Hello, can you list your system specs?

After discovering your post, I decided not to push my luck with a 6870 on a Corsair VX450.
Ordered a Visiontek 6850 from Amazon for $199 on Monday, arrived Wednesday. Retired my trusty ole' Visiontek 4850 512MB. Good times.
6850 installed without a hitch using Catalyst 10.10e hotfix.
BFBC2, Dirt 2, LFD runs great and looks purty! Maxed settings. Low idle & load temps. Fan has yet to rev up.
