You need a jump starter bridge something like this

Yeah, that's exactly what I meant by "terminator cap". LOL. I couldn't think of the correct term. It came in the box with my PSU. You need to cap off (or terminate) the end of the long cable that would normally go to you PC.

Sorry for any confusion.

You need to jump across a couple pins to turn on the psu - normally the power button on your computer does this but we're not using the psu in a computer, right? Look for the PS ON pin and connect it to any COM pin. PSU turns on, and so does anything attached to it!

Yeah, it feels like OP isn't doing anything with the motherboard connection.
The PSU doesn't magically turn on if there is no connection on the MOBO connector.

May you please specify on the terminator cap? I never heard of that term or seen something like that.

Hey guys, I am new here and to bitcoin mining in general. I live in North America and have two Antminer S7s connected to two EVGA 1600W PSU individually. I used the EVGA PSU tester to make sure the PSU is not defective and the PSU kicked on. I then hooked the two Antminers to the PSUs and nothing kicked on. There were no lights on the antminer S7s and the EVGA PSU did not kick on. Is there a voltage issue here? And if there is a issue here, how can I fix it?

Did you power all 3 hash boards with 9 PCI plugs. AND the controller board with 1 more PCI plug?
Are your fans plugged in correctly?

I have run an S7 and now an S9 with an EVGA1600. No power issues for me. Just got to use the right cables that should have come with the PSU's.

PS. On the EVGA 1600, you have to remember to put the terminator cap on the end of the long cable bundle.
