IMO if overclocking is involved or undervolting it is possibly best to fix a CPU at one speed with power saving modes disabled. It is impossible to test all the different modes. We only need the fastest anyway.

BTW have you tried underclocking and further undervolting to see how that affects efficiency?

Latest update: CPUs 4 & 5 added. Right now all the h110 mobos are running with the CPU undervolted by 40mV except one at 30mV. All RAM overclocked and running at 1.20V except one required 1.25V.

Draw is 295 watts at the wall without any case fans running or the network switch running of the PSU. This has turned out so well, I need to re-evaluate the cost effectiveness of keep the OC'd Sandy Bridge/Haswell/570/580s running.

Stability testing and DC testing continues.... I also need to figure out how to wedge the network switch and stack of 5 mobos into the case.

BTW, the $25 ebay cables (four PCI-E to triple 12V barrel plugs) arrived and tested OK. I was quite satisfied with the build quality. At $2/barrel plug it is a pretty cheap solution. I may buy another set of 4 to repeat this project in future years.

Tough crowd.

Next up is to replace that long USB stick with something smaller and then squeeze that stack into the case, drill four holes into the case bottom and screw it down. Then somehow clean up the maze of wires. I haven't quite figured out where or how to mount the network switch in the case.

The case has room for a 5-high stack on the left and another 2-or-3-high stack on the right. I may not put in the second stack because there may not be room to attach monitor and keyboard cables when necessary.


Edit: Sorry, for some reason the forum software or my Mac rotated the pictures...

Can't help with the power supply wires, but if you're looking for short ethernet cables, Monoprice is the place to go.

That's a combination of the camera and the forum software. A while ago phones and cameras started putting in an orientation flag in the exif data of pictures. Instead of rotating the picture data, they save the picture straight from the camera sensor and save a 0/90/180/270° orientation.

The forum software hasn't been updated to copy the orientation data when resizing pictures (or to do the rotation as part of the resize).

You could remove the case to save some space, it appears.

An interesting idea -- a lot of air in there.

Do you think there will be a problem snipping the power cord and splicing it into 5V from the PSU?
