ASUS KGPE-D16 Power Supply: Silverstone SST-ST85F-P

Silverstone-SST-ST85F-P

One of my ESXi nodes is a build out with an ASUS KGPE-D16 motherboard that sports 16 cores and 64GB of RAM. One of the challenges with this server build is that the ASUS KGPE-D16 motherboard requires two 12V EPS connectors from the power supply, and not many power supplies actually have these connectors. In fact, one of my favorite places to go shop for power supplies, NewEgg, doesn’t have a way to search for power supplies with dual EPS 12V connectors.

ASUS KGPE-D16 Power Supply: Dual 8-Pin EPS 12V

After a good bit of searching over the web, I found that Silverstone actually has three power supplies that have dual EPS 12V connectors, and Silverstone is a solid, respected brand. Note that these are not the only power supplies with dual 8-Pin EPS 12V connectors, but these were the most readily available ones that I found from a respected brand. The 850W version is the the Strider Gold ST85F-G, while the 1000W version is the Silverstone ST1000 and the 1200W version is the Silverstone ST1200. For me, the 850W version was plenty of power, and that’s what I got.

Note that since I posted this, between the emails I have gotten from followers and comments below, I am tracking less than a 50% success rate for people getting this board working with two CPUs. This is regardless of what power supply is used. Be aware of this, buy from a source that will allow you to return all your parts, and be prepared for either lots of fiddling or possible outright failure. I had good luck, but I feel compelled to offer this warning.

  • My build is working fine with dual processors and this particular power supply. This sounds more like a hardware issue with either the 2nd socket or the CPU itself.

      Yea driving me crazy. I just purchased two 6128 and same issue. Going to try to RMA the board again lets see what happens.

  • Giovanni Gaccione

    I ran into this myself. I’ve RMAed the motherboard and even sent back the CPU’s. I tried putting both CPUs in the first socket and they both work but when I put one in each I get no post. I’m using the 6164 HE. I’m thinking of trying different processors at this point.

      I’m setting up a similar config at the moment and am having the same issues (both CPU’s work fine in socket #1, as soon as I plug both CPUs in each socket no POST). Did you resolve this issue?

      • Unfortunately, from the emails and comments I have gotten, this board has a less than 50% chance of working with both CPUs. Am not sure if it’s a problem with hardware, or if this platform is just that bad, but I’m going to be adding a warning to this article.

          Hi Don – Thanks for replying!
          Frustrating to say the least. I purchased the board over a year ago and am only getting around to the build now. I’m hoping that ASUS will still RMA the board if I can do further testing with another PSU. I’m using a Corsair HX750i with 2x 8-pin cables (plenty of power). I’m just second guessing myself. I’ve read on other forums that some have used splitters to run the second socket off another one of the PSU’s rails…

          • Good luck, and I’d love to hear from you if you get it working. I’ve added an alert box to this post; this page is pretty high up the rankings for this subject, and even though this is an older board/CPU, it’s an attractive proposition for home labs looking for tons of cores cheap, and people are still looking for them.
