So it looks like i need something bigger than 1000w afterall

post #1 of 52
Thread Starter 
Hey all, so currently I am rocking a kingwin lazer platinum 1000w which is a great power supply if anyone is looking for one around 1000w. But I am thinking about adding a 4th 7950 for some benching and it wont be enough.

What would be a good power supply that could handle 4x 7950s (or 7970s or 8970s or 780s etc) and a 3930k when overclocked?

Has to be at least semi modular (full modular would be nice but not required)

A 'LEPA G1600'

It outputs 1600w, it has more than enough headroom for Quadfire 7950's and a very power hungry CPU that yours is

Like said above Lepa G or Lepa P the G is a rebrand of the Enermax Rovolution 87+ and the P is rebrand of the Enermax Platimax

The Platimax is more or less just a pimped up Rovolution 87+ with a 80 plus platinum bage

some guy here was getting over 1450 watt from the wall with clocked quad 7970's before his seasonic 1250 shut down so you gonna need 1500+ if you want to get serious

the Lepa 1600 seems like it will work as long as I have nothing else on that circuit.

That seems to be my best bet for that much power?


edit: also it will be nice to have a power supply that should be good for just about any crazy ideas I come up with lol

Lepa 1600 is good to about 1300 core clocks on quad 7970s. Now u kinda have to have four cards capable of that to have that sort of problem in the case you needed more go juice. It's a nice problem to have.

Good to know, thanks. You have been happy with yours I take it?

I am waiting to see if amd is going to announce some new cards here soon and then I might get 4x 8970s if they do

My ST1500 got me to just under 1300 core clocks, so I switched to the Lepa. The Lepa got me to just over 1300... hmm its been a while but I would say around 1320/1330mhz before shutdown. If I only bought one psu I would like the Lepa more. I do find it's rail setup annoying cuz half the gpu rails share load with the accessories. Thus with a big loop, ie. multiple pumps u will want to load balance your loop amongst the rails or you will starve a gpu. That design of the psu I dislike. It's a good psu, but it's not enough power for me. I have to bench with two psu.
