Wattage for 2 cpu and 6 gpu?

post #1 of 7
Thread Starter 
Hey guys, so i been trying to figure out a theoretical wattage that i might need for a planned build. tongue.gif The build consists of these parts:

-Two Xeon E5 1650
-Two GTX 690/790
-Two GTX 470

Since the GTX 690's arent out yet i have been assuming they would be using around 375 watts each, but not really sure how accurate that would be; Also didnt really know the power consumptions of the Xeon E5 1650. confused.gif Bassicly looking how many watts the system might take since im currently trying to figure out power supplies. frown.gif

Any help would be greatly appreciated biggrin.gif Thanks!

1200W or more? I'd say 1500W I guess, just a guess so you know.

What are you doing with 2 CPU and 6 GPU? Folding?

Hmm.. i get a bit worried using calculators (maybe im a little paranoid >__< ) but it says i should need 1244 watts @ 90% load (Using gtx 590's and K cpu's) Thanks for the input! +rep

hmmm, honestly im not sure as well (especially since the 690's aren't out tongue.gif ) but maybe i could use a 1200 watt unit dedicated to gpu's and another unit for cpus and system needs? confused.gif
Anyways +rep

mmm CA (For work) and occasional folding on the cpu's 690's mostly for gaming and the 470's are going to be for folding. Kinda was looking for a do all machine for the next 3-5 years so going a bit over the top i guess , But durring chimp challenge i was going to use the all the gpu's and cpu's for folding =\

That's literally the worst excuse I could think of to build such a ridiculous contraption =))

On topic, you make some strange assumptions.. that nVidia will put out dual GPU cards this generation, that they'll be called GTX 690, and have a certain power draw(based on the PCIe limitations I suppose).
Assuming all that is indeed correct and you're a genuine soothsayer... and that the cards will also be available in time for the 2013 Apocalypse.. I'd say you need to pass the joint cause I gotta have what you're smoking, and also call it a ~2KW rig since folding is on the menu.

smile.gif tbh always wanted a dual cpu rig, and the GF offered to pick me up a SR-X for my birthday since she just started her new job tongue.gif But the dual cpu should help her alot for her work so seems like a good investment for her as well.

but yeah basing the power off of two 8pins (150 watts each i think it was) and the pci-e lane power draw (75 watts), since i cant think off the top my head, nvidia putting out a card with more then 2 power connector as reference tongue.gif came up with 375 watts

hmm, so i might be looking at 2k watts? frown.gif well i do have two 1200 watt psus i could use (as well as a 750 watt), originally i thought that the second 1200 was overkill >_< guess not

Thanks for the input! +rep
