How many watts does a 7990 take up

[xtremegamer2da-max]

i know its not out yet i know it might be a failure but since so many things leak i thought id ask how many watts i will need just for a radeon hd 7990

A single one? If so, an 850 watt power supply would be the best choice. (i.e. Corsair AX850) but you might be able to squeeze by with a 750 watt.

i want the watts for JUST 1 7990 not including a cpu, mobo, ect. JUST 1 7990

All of them. Eh you're just going to have to wait till it's launched to find out. Don't be surprised if it uses 350W or more. After all, an overclocked 6990 can use more than that if it's power tune limit is raised. We'll just have to wait and see.

We don't know yet since the GPU isn,t even released yet but we know that:

a single stock 7970 use up to 214W to 280W loeaded.

a 6970 use 198W to 254W loaded

And a 6990 use 328W to 352W loaded.

So lets guess the 7990 will be around 350w to 400w is something realy possible and that is all on stock clock.

I'd say none I realize I'm not answering ya question and I don't mean to be a weisenheimer ...... but consider this.

....if it performs as well as the 6990 did compared to the 6970 and 6950 (same for the 590 and the 580, 570, 560) I couldn't ever make a case to install one ..... two of the single GPU cards which would be cheaper and produce comparable or higher frame rates.

Guru3D uses the following games in their test suite, COD-MW, Bad Company 2, Dirt 2, Far Cry 2, Metro 2033, Dawn of Discovery, Crysis Warhead. Total fps (summing fps in each game @ 1920 x 1200) for the various options in parenthesis (single card / SL or CF) are tabulated below along with their cost in dollars per frame single card - CF or SLI:

$ 240.00 6950 Frozr OC (484/759) $ 0.50 - $ 0.63
$ 320.00 6970 (526/825) $ 0.61 - $ 0.78
$ 725.00 6990 (762/903) $ 0.95 - $ 1.61

So one 6990 for 762 fps at a cost of $725 or 95 cents per frame ..... two 6950's for 759 fps at a cost of $480 or 63 cents per frame or two 6970's for 825 fps at a cost of $640 or 78 cents per frame ????

$ 205.00 560 Ti - 900 Mhz (495/862) $ 0.41 - $ 0.48
$ 340.00 570 (524/873) $ 0.65 - $ 0.78
$ 500.00 580 (616/953) $ 0.81 - $ 1.05
$ 750.00 590 (881/982) $ 0.85 - $ 1.53

One 590 for 881 fps at a cost of $750 or 85 cents per frame ..... two 560's for 862 fps at a cost of $410 or 49 cents per frame ????
