Voodoo Lab

Sorry to ask what is probably a simple question, but I'm running into some troubles and need a hand.

I'm building a board with:
HX Stomp XL (1000ma)
HXFX (1000ma)
Source Audio C4 (300ma)
Neuro Hub for C4 (40ma)

I purchased a Voodoo Lab Pedal Power x8, and it isn't doing the job. The red light next to the power input on the PSU flashes every couple of minutes, and all of the pedals reboot. I have the correct HX cables for the Stomp and HXFX.

If anyone can provide some insight as to what the problem might be, I'd be grateful! TIA
