Help me to choose a PSU (6*7950)

[mediafire77]

Hello everyone,

I pretty much have everything together for my setup, except the PSU!

6 * 7950
on
MSI Z77A-GD-65

Delivery of the LEPA G1600 got cancelled today with no chance of getting this PSU anytime soon, so now I don't really know which PSU I should get. The only condition is to cost about 300€ max.


I was thinking about this one:

Platimax 1500W EPM1500EGT ~ 295€

What do you think about this? Any tips from someone with more experience?

Best regards :-)

My advice, is to get two 750+ and daisy chain them together.  Less ideal yes, but might make your shipment and price requirements.

Excellent choice.  Got two of those. Go for it.

Do you think 1500W are enough for this setup?

I don't, my 7950's run at 275ish... I have 1500W on 5 cards and the mobo.

I got 5 7970s on it. Whole setup pulls 1450W at the wall. So I think 6 7950 should be possible.
But you will max out the PSU. And shouldn't try overvolting or heavy overclocking without monitoring with a power meter, otherwise you might burn the PSU out.

I would undervolt and probably overclock...

Don't really know if the 1500W one may be little too weak, but I also can't find anything like add2psu here in Europe.. Don't know what to do now

1500W will be ok with undervolting and moderate overclocking. Thats what you should do anyway, to make it more cost effective.
