Server Supply Breakout Board

We are in the process of developing a board for breaking out a 12V server power supply. Boards will be available Thursday, March 6th at 9:00 AM (Central Time). Place orders by emailing Any orders placed before 9:00 AM central time will be ignored.

A couple of people have wanted to know how these mount, so below is a picture of the mechanical layout of the board, as you can see there are three screw holes which should be suitable for either M3 or #4 screws.

Q. How can I buy these?

A. By emailing We take payment in either paypal or bitcoin.

Q. What power supplies can you use with this?

A. Server supplies typically have strange connectors, so you can only use boards with the power supply they were designed for. Obviously, we plan to make boards for the supplies which would be most useful to people. We are selling Dell 2950 Powedge Server Supply, and we are designing a board for the HP DPS-800GBA power supply. The DPS-2000 has also been suggested and will probably follow. Both of these supplies are plentiful and cheap. Got a recommendation? Let us know.

Q. What features are be available?

A. We have a 0.1 inch spacing pin header which breaks out commonly used power supply features:
+ 5V and 3.3V outputs for driving auxiliary controllers.
+ The current share pin to tie together if you wish to use more than one power supply at a time.
+ Current sense pin, to measure current consumption.
+ External fan speed controller.
+ External on for turning more than one supply on at the flip of a single switch.
+ Power good signal to indicate whether the supply is functioning properly.

Q. Why would I buy your board instead of just using a large ATX supply?

A. Our board is cheaper and has more features. You can buy server supplies that run at about 90% efficiency for $10 bucks and put our board on. Most large ATX supplies with a high current output on a single 12V rail are very expensive. Server supplies are designed to share load, so you can just add more supplies until you have enough power. Since the cables are whatever the user decides, there's no need to deal with the octopus of cables on an ATX supply. You can run an auxiliary controller, measure the efficiency, and still save money. Plus, if a supply fails, you can replace it at minimal cost and reuse the controller and the cables. For applications that require redundant power, you can even hook up enough power supplies to function redundantly, and no suffer downtime if this occurs.

Q. What is the power out connector on these boards?

A. The power connectors are screw terminals, so you can use whatever cables you want. We are selling 18 inch cables with a spade connector on one end and 6-pin PCIE connector on the other for $3.50.
