So during my GPU mining days I bought huge Thermaltake 1475W Gold power supply, and it's been sitting in the corner waiting for a miner to play with. I have a Jupiter and a Saturn on order, which means my total power needs should be around 1000 watts. The PSU has 4 sets of pci-e power connectors, so it could technically run two Jupiters and still have over 200 watts in reserve.

The questions is; should I actually run two miners from the same PSU? My intellectual side says it's fine, because it'll be more efficient at the wall having just the single PSU plugged in. My paranoid side thinks that something might get fried in the PSU and I lose two miners 'stead of one.

Here's the PSU I have:

I also need to purchase a UPS to protect my miners. I was thinking of something like this:

Would this suffice for two miners? Should I go bigger? I know power here in New Mexico can be very flaky sometimes, but it's relatively cheap at 12c kwh after fees. Still need to protect my investments though.
