Here are the official power requirements for the brand new ATI Radeon HD 5850 and HD5870 video cards.

ATI Radeon™ HD5850 System Requirements

PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
• 500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in • dual mode)

ATI Radeon™ HD5870 System Requirements

• PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
• 500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in • dual mode)

NOTE - These are the power supply recommendations for an entire pc system. I can't wait to see techncial reviews with power consumption results. I knew the cards were supposed to be more energy efficient than current generation cards.

I was hoping HD5870 will be $299 not the HD5850.

I'm stoked. I had just assumed with the new cards, my 650W OCZ wasn't gonna cut it, but sounds like it will.

I'm hoping our local importers got some in ready for sale, otherwise we probably wont see any for 4-6 weeks. I neeeeeeeeed new video card goodness. 299 for the 5850 is probably fair, assuming it outranks other 299 range cards.

Wondering how it goes - 5850 vs 4890?

The vendor's site was showing $299.00 for the 5850 and $399.00 for the 5870. Those are prices that were also mentioned in other web articles.

Awesome! Minimum power required to unleash a graphics madhouse! Can't wait for 5850 crossfire :love:
Its disgustingly unnecessary but I...must...have.

I just read half a dozen technical reviews. Power consumption looks good. The Tom's Hardware review showed the highest system power consumption with two 5870's in dual Crossfire mode but the test system was equipped with an Intel Core i7 975 Extreme Edition Bloomfield overclocked to 4.0 Ghz. In other reviews system power consumption was lower with an Intel Core i7 920.

The 5850 will be introduced next week.

Anandtech has a total system use at load for 2 - 5870s in crossfire and a moderately overclocked i7 920 to 3.3 GHz to be 664 watts.

dirtmountain - I saw that. That was using OCCT which is a stress testing tool that creates a load much larger than any game. 4870 X2 and 4890 both crashed as soon as OCCT started. Their chart for World of Warcraft was much more realistic for gamers. An Intel Core i7-920 @ 3.33GHz system with two 5870's in Crossfire mode used 430 watts.

Thanks for the information, the last time I read about ATI updates was when I upgraded to HD 4830 and now there's a HD 58XX series available! Looks like I'm years behind. LOL!

Yes, I agree. ATI always has a way of getting their price low but at least offer almost the same performance with its NVIDIA counterpart.
On a 2nd thought I guess this works at all business levels, however, with AMD's performance on its CPU, Intel is killing it and beating AMD's a** well.

Maybe they should spend their profit to better R&D for their CPUs.

I pretty much agree, however there are always some graphically intense areas in almost all games that will pretty much load the GPU and CPU. These are usually the "end encounters" or the critical parts of a game. So while a 650w quality PSU might be enough in day to day running of crossfired 5870s, i'd still recommend a 750w or greater for any overclocked system.

I agree with your suggestion, its good to make allowances as O.C. would sometimes "tweak" your system uncontrollably. Just review which PSU brand you are buying some offers 750watts PSU though their volt/ampere rating isn't correct. I read on other articles that there are times when the PSU rating is correct but still can't run crossfired 48XX GPU.
Just my 2 cents.
