Hi!
Which PSU should I buy, if I will have HD4870X2, E8400/8500, 2GB DDR2 and 640GB HDD?

Is this enough?

–650 Watt or greater power supply with one 2x3-pin PCIeR power connector and one 2x4-pin PCIeR power connector is required (1K Watt with two 2x3-pin and two 2x4-pin connectors for ATI CrossFireX™ technology in dual mode)1

–Certified power supplies are recommended. Refer to http://ati.amd.com/certifiedPSUfor a list of Certified products

ya that is more then enough. a good quality psu with 600-650w would still do.

thats insane. i remind you folks to not look at your electricity bills. you'd get hearts attack. ATI should solve this power hungry problem.

Keep in mind that the latest Nvidia cards drink a lot of power as well. I wonder if this is just the price that will have to be paid if enthusiasts keep demanding ever more from the cards. It can't be expected that we get continuing increases in performance without having to pay for it someplace.

As to the power requirements, I think there should be more emphasis placed on the phrase "minimum requirements". Yes, the given power level is a minimum requirement, but if an enthusiast has multiple hard drives, overclocks everything in sight, etc, the size of the needed PSU will be very high. The need to have a dedicated electrical circuit in the house to power the computer becomes closer to a reality all the time.

As for myself, I'm passing on this card.

That PSU doesn't have any 8 pin PEG connectors, so it won't power a 4870X2 without some sort of adapter.

I strongly recommend the Corsair TX650. It has the requisite 8 pin connector (actually it has two) and it's just an all around great PSU for a great price.

4870x2 board alone is rated at 270Watts... The 280 is ~ 236Watts

OK, for those still wanting to get a first day release, newegg is out of the saphhire, but check out mwave.com and provantage.com. Provantage has it for the cheapest, but I dont trust them as much. Mwave is approved by ATi and has it in stock and cheaper than newegg (as of 2:46 EST 8-12-08).

Ok, I have an update on the PSU.

Although a 750w should work, the issue you will most likely have is at least 1 8pin power connecter. It needs to be a 3v rail as well. I had an issue last night installing mine with a thermaltake PSU so I wentr out and bought a 1200w thermaltake to ensure that I have more then enough for my 4870x2, 8gigs of ram (witch will be OC), 4 hd, 1 q6600 (witch will be OC), and everything else.

Yes a ~750w PSU will work (make sure its a very high efficency) but you will have to have a bare system to do so, no OCed parts, and at least 1 3v 8pin rail and a 3v 6pin rail.

lol who said that 2x4870 in CF require 1000W.

A good 750W PSU will easily be enough for the 4870x2

I have 2x4870 in CF with the corsair tx750W and the 4870x2 uses less power. I also have a q6600 @ 3.3, 4 gigs ram, 2hdd and a lot of fans.

Reply to lameness

it not that it cant, its the connectors. Plus, you have more than enough power to upgrade from there if you feel the need.
