What PSU do you recommend?

[szala11]

Hi!

What PSU do you recommend for two 4870 AND for two 4870X2? I would like to buy a modular PSU, one without so many unneeded cables.(I can attach these cables later in case of installing other stuff)

Thanks

What's with that setup? You've got to be kidding me!

If it has to be modular, there aren't many viable choices.

Frankly, I'm not certain it's enough. Well, there is always this monster:

Giving the crazy prices of ultra-high wattage psus and lack of choices, you might want to consider using a good value high wattage mainstream psu plus expansions instead.

What the heck are you building? Is this something to help you take over the world?

P.S.....why not a third x2 rather than the two 4870s...?

I think he wants a PSU recommendation for two HD 4870 and another one for two HD 4870X2.

For two HD 4870: Corsair 750TX, PC Power & Cooling 750W, Antec 850W
For two HD 4870X2: Corsair HX1000, Enermax Galaxy 1000W

If he meant a PSU for all 4 cards at the same time, that $650 monster that Dagger found sounds good. But considering how GPUs scale, it won't be as great as it looks. He'd get nowhere near 6 times the fps of a single HD 4870.

Edit: I know some of these are not modular, but if you're going to use most cables anyway you don't get much advantage from modular PSUs. They just cost more and have additional points of failure at the connectors.

Yeah, i meant separately the two 4870 X2 and 4870. In case i upgrade later to two X2. I will first use two 4870 with this config:

ASUS rampage formula
Q9550
ASUS Silent Knight II
2x2 GB Corsair Dominator
HD 4870

Here's a list of PSU's certified for HD 4870X2 with 1 card or with 2 cards. The PSUs that appear there with Number of cards=1 will also do nicely for HD 4870 Crossfire, of course. The ones that appear with Number of cards=2 will do for anything.

http://game.amd.com/us-en/crossfirex_components.aspx?p=3#ATI Radeon™ HD 4870 X2

The list is a bit weird, so don't take it too seriously. For example the Antec TPQ-1200 (1200W) is listed as supporting only one HD 4870 X2, while the OCZ EliteXStream 1000W can support two cards according to them.

The Corsair 1000HX is not on the official list but I'm sure it will do.

The Enermax Galaxy 1000W is on the list, and it's about $24 cheaper after shipping:

For prices like that, get a 1000w pc&p unit instead:
