I'm trying to get 4 quad video cards running in one machine (16 displays total). I can get 8 displays to run, but whenever I put in the 3rd quad card I get a wonderful BSoD. I thought that since the mobo has a molex for supplementary power I'd be ok, but that seems to not be enough. Any advice/suggestions would be greatly appreciated.

Mobo: EVGA P67 FTW 160-SB-E679-K2
GFX cards: 4x JATON VIDEO-PX309-QUAD Radeon HD 3450
PSU is rated for 1000W

Thanks for the response.

I did try to find one that had an external power connection. It was $100 more per card and double thickness so I couldn't fit them all in the same PC anyway.

I found these but I wasn't sure if they'd even help. Anyone used one before?
