Will My Power Supply Be Enough For Dual 6990s

[Darkstar757]

I have a Corsair CMPSU-1000HX currently. I have two ssd and three SATA Hard Drives?

Will this PSU be enough to handle it?


Thanks,
Darkstar

HardOCP pulled 886w from the wall but they used a sandybridge. Your OC i7 920 will use more than that, but your 1000w PSU should be able to handle it.

I like to keep spare capacity on PSU, so I have 1000W Coolmaster +450 auxilary PSU. See my sig for rig and power draw...

sell me your 5970s i want to make another bitcoin machine

I'd look for something more powerful if you're going to drop the coin on some monster cards. Do you plan on overclocking? Running the Stalker: COP benchmark, I pulled ~750W from the wallplate with an i7 920@4.2GHz and 6950's@900/1400. You could probably get away with your current Corsair if you don't overclock your system but I wouldn't want to run that close to the limits of the PSU.

I'd recommend doing what pcm did and get a second power supply dedicated to one of the 6990s.

I would avoid buying two 6990's to get that extra 20% faster graphics

Wait for the HD7990 Videocards on 28nm to come out ( less then 6 months )
with "over" 6000SP!!!! it will be almost 300% faster then two 6990's

People who jumped onto GTX590's and HD6990's will be crying bigtime when the TRUE new gen graphics cards come out and not just some 10-15% jump refresh nothings.. that are restricted to the old 40 nm tech that's been around since the HD4770 (40nm)

Best of all two HD7990 dual core cards should run on a 800w power supply with ease.. again all thanks to the full node shrink to 28nm .... its going to be the single largest advancement in videocards over the past 3 years.

and even a midrange to lower highrang single 28nm GPU card will be marginally faster then a single HD6990

Everything in your post is pure speculation. We have no information on the type of performance that a single HD7970 will offer. There is no way a mid-range $200 HD7970 will be faster than a single HD6990. That I can pretty much guarantee. Not even a single HD5870 was faster than HD4870 X2. Also, gamers who buy $700 graphics cards will probably upgrade to HD7990 the week it comes out anyway.

Too late now the cards have been bought. Damn I wish I had knew this earlier

Darkstar757, at the end of the day if you use them in those months until the new vid cards are out its kinda worth it... if your just benchmarking with them then probably not so much!
