Product Description

Dual Fault Protection Cable Kit to Link Power Supplies

One of the unique features of the X11, X7B, or X6B Board is the ability to link power supplies together in such a way that if one power supply fails, then the second will automatically shut off.

We are often tempted to power a single hashing board with two power supply units in ASIC mining. An example of this would be with an Antminer S7 requiring 1400watts because in today's market, the cost of a 1500watt PSU is very high. What if we could power the S7 with two 750watt, which are much cheaper and just as good. We can't as we would need to divide the power of two 750 into a single hashing board. This is playing with fire because if one PSU fails, then the other will power 1/2 of the hashing board; everything will get real hot, real fast.

The X11, X6B, and X7B solves this problem with what we call "Dual Fault Protection". This cable kit combined with two X11, X7B, and/or X6B syncs the power supply units together; if one fails then the other automatically shuts off, consequently protecting your equipment.

** This mode renders the on/off power button inoperative. Turn the linked power supplies on or off by cutting the AC flow IE: unplugging the power cord  **  


  • (2) individual fault protection cables, must be used together.

Can this be used with the x7 and x8, breakout boards

1 year 2 months ago

No – Only the X11 and X6b “will be available this week at $22” can use this feature. The X6b is exactly like the X11 except it as only 8 ports and a smaller footprint

Hi – what should I do if I want to use 3 PSU with failure protection?

1 year 2 months ago

Unfortunately at this time our fault protection feature only works for two power supplies at most.

This feature was design for two only.
