Dual PSU mining Rig

[lielianjie]

Hi Guys,

I'm building a new rig with 3 290x and I have 2*750W PSUs.

In order to share the power consumption, do I need this http://www.add2psu.com/ ?

Thanks

Yes, You do something like this to power both PSU at the same time on MOBO power signal. There are other thingies like this, You can check ebay

Well, I did the bridge method explain here : http://www.youtube.com/watch?v=xZiWciJLK3o but I have a problem...

I did the bridge with a between the green an black wire on the second PSU.

Both of my PSU are runing ok BUT as soon as I start mining, the second PSU shut down right away.
I tried to reverse the PSU's but the second one stop systematically when I start mining.

It looks like the PSU go in some kind of security mode or what ever but can't manage to mine with both of my PSU.

Can someone help me with that ?
