Build Advice Quad GTX295 needs more then 1200W PSU WTF?

You need a different PSU, not a bigger one. Prefarably one with a bigger single rail

 

Use both colored pci-e connectors (yellow with blue, yellow/orange iirc wiring) on the psu. That should be more than enough

 

Zalgard, listen to everybody here, you dont need a power supply with more wattage you want one with a single high amp rail, such as the HX1000, and if that is enough to run quad crossfire with a 965 clocked at over 4GHz, both of the 2870X2's clocked highly, and running watercooling for it all......
Read through the thread, these guys know what they are talking about.....

OMG you dont need more power jesus!!!
you just need better rails!

 

You guys do realise the HX1000 is also a multi-rail part and almost the same as the Odin?

Both are made by CWT and have two lower power PSUs shoehorned into a single unit.

It's 12+5 on one and 12+3.3 on another, from both. Even Thermaltake 1kw+ use CWT, the component choice just differs slightly.

 

We ran dual GeForce GTX 295s in Quad SLI from a 1,000W Enermax Galaxy DXX without any stability issues whatsoever. There were driver issues, though...

 

You could add a supplementary PSU to one of your drive bays as a cheaper alternative to getting a whole new 1000W power supply. It will take up a slot in back too though and those might be scarce in a PC with so many GPUs.

Welcome Wopsh!

It shouldn't need another PSU though I'd send the Odin back to be honest.

 

Nope this machine will no doubt require and diesel electric generator running at an output of 7.8Kw

should fix your problem!

Quick question, are the guys using a dirty power outlet to plug this into? If they have dodgy wall supply no matter what the PSU is it will still throw a fit!

 

4 x GTX295?

Do you realize that you'll be disappointed with the results vs price right? ... There was a text with multi GTX298 and more than 2 is not worth it ... even 2 GTX295 have optimization problems...


Well but the trick is to use multi PSU
You'll need about 2k

 

HAHAHA Post u understood it wrong
there wont be 4 cards in the system
IT would be 2x295gtx = Quad GPU
Who would even think of 8 GPUs on the same rigg, its like....well... dumb? lets leave it at dumb hahah

 

Ups sorry!

( By the way its not a GTX298 ... but 295... typo ... )

 

Got to hate stupid power supply designs. And they actually make us pay for PSUs that in real life can't provide the specified power to where it counts

 

IMO , and mainly a plan for my future, is design a secondary PSU ONLY for the 12 Rail volt,
It would be a really big 12 Rail volt for the GPUs since it clearly looks like it is the tendency and leave the primari PSU for the rest of the rigg haha
Thats my millon dolar idea! Darn! i said it out Loud :S

 

don't worry, no one will nick it! lol
Dual PSU isn't worth it really. You will be hard pushed to find a rig that can't be run off one PSU, not many need more than 1KW.
