Had a storm last night and the damn power went out. Problem is I can't get to the rig and get it going again until 8pm my time (9:35 now).
This happend to me too once. Now I'm running vpn on router and I enabled Wake-On-LAN on rigs, so I'm prepared next time.
That's not a bad idea. I have have two psu's running my rig (on is piggy-backed on for 2 of the gpu's), so it wouldn't work for me.

I just have all my hardware set to automatically start after a power failure. And I have 1 rig that has two PSUs, but both PSUs are tied into the 24 pin motherboard connector (using
a splitter) so that they both turn on and off with the computer.
Personally, I prefer to use a relay on one of the molex connectors to trigger the second power supply. But now that dual power supplies are more common, it is nice to see premade splitters so that people don't need to cut and splice their gear.
