Re: Octominer B8PLUS 8 PCIe Slot Mining Board (Motherboard, integrated CPU)

I've installed the RAM, plugged in 2 PCI-E cables as per the quick start guide but then turning the PSU on does not power on the board.

OK. Please contact us through our website Live Support chat and we will help you get your board up and running.

I have tried 2 other boards with 2 different PSUs and none of them is able to power on.

Turns out I needed to plug a dummy plug/jumper into the 24 pin which wasn't mentioned anywhere.

Glad to hear you got the problem sorted out.
We actually included "ATX JUMPER PIN" adapters with all the ATX PSUs so our clients do not have to make their own jumpers. Unfortunately for the first few orders our shipping agent forgot to include those. Sorry for the inconvenience.

Good to know!
