PCI-E powered risers by SATA?

[Silvano]

Hi all

i'm building a new rig and i've to decide which psu to buy
now i have some doubts

i have 5 sapphire HD7950, they are undervolted at 0.968V for a expected consumption about 140w each, and the expected total consumption is about 750w including MOBO and CPU.

i'm looking for PSU "be quiet! Powerzone 1000w modular 80+ bronze", that is a very good deal, unfortunately, PSU has 10 connectors including PCI-E and Molex, it remain uncovered the 5 connections to the risers.
(HD 7950 has 2x6pin connectors)

1st query: need to connect risers to power?
2nd query: if yes, is it possible to connect risers to the sata plugs by an adapter?

what advise me to do?


PS: i will order next monday.

Some risers can be powered by SATA. Look here:  https://bitcointalk.org/index.php?topic=429780.0

That is only one seller, who is out of stock now. I have no experience with that seller or any other, i'm just providing a link.
