Silverstone Strider 1500w PSU & Triple SLI 780Ti (2x 8pin PCIe)

post #1 of 2
Thread Starter 
My current build contains 3x GTX 780Ti video cards which require a total of 6x 8-pin PCI-e power connectors.


To power this build I picked up a Silverstone Strider 1500W PSU


The top row of the PSU has 4x 8pin PCI-e and 2x 8pin CPU power. Therefore I need to figure out how to supply power to the 2x 8pin PCIe on the third video card.

One thought I had was to use those 2x molex to 8pin PCI-e converters, however I doubt this is an efficient way to go about it.
CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 99

Another thought I had was to use the both 2x 6pin PCIe to 8pin PCIe cables that came with the PSU to connect to the third video card, by using the 4 extra 6pin PCIe power cable that splices of each of the 8pin PCIe power cables. However I also am not sure if this will work.


The last thought is to simply add a second small power supply to the rig that will power up the 2 additional 8pin PCIe on the video card.

So I'm just curious as to what kind of suggestions anyone might have to supply sufficient power to the third video card's 2x 8pin PCIe power. I'm open to the idea of just getting a whole new 1500W PSU that has 6x 8pin PCIe power, however I'd like to do this only if all else fails.

Just an update, in the end I settled for buying a new PSU which I received today and I couldn't be more happier with this decision.

The PSU I picked up was the ENERMAX Maxrevo EMR1500EWT



This fully modular PSU's cables are extremely easy to work with in terms of cable management and the physical size of PSU is far less than the Silverstone Strider so I might squeeze one of my extra 140mm or 120mm radiators into the case along side the PSU smile.gif

If anyone is interested in a good 1500W PSU for powering multiple GTX 780Ti Video Cards then I highly recommend this PSU.
