Ok, a clarification on the thermaltake psu. It's got EIGHT 8-pin pci-e power connectors on four cables, which is what I meant by four connectors. Each cable splits into a pair of 6+2 pci-e power connectors. It will definitely power two miners.

Which leads back to my original question: Should I run two miners on one psu? Is it safer to run a separate psu for each unit? I do have a spare 650W corsair psu, which I could use for my Saturn and save the Thermaltake for the Jupiter. This may not be as efficient at the wall, but it could prevent both miners from crashing if a single psu fails. How often does that really happen with a 1475W thermaltake gold psu, though? The geek in me says I should use the single PSU for both units. Not just for efficiency of electricity, it means having less power cords to deal with and less space taken up by external psu's.

80+ power supplies are most efficient at 50% load, if that helps with your decision.

I hate fan noise so the plan is to have the PS fans at low dB.
I have spent too many years on a raised floor surrounded by 9million fans,
and on weekends I hang around on turbo prop aircraft.
What am I doing mining if I hate fan noise??? Who knows?
Some of us are here because we're not all there!

I went with platinum and targeting/guessing at 50% based on KnC recommendations.
I expect the PS's will far outlive the miners so it is not a waste.
I also went with twice as many Saturns instead of Hoopiters.
It is more expensive but more flexible IMneverHO.
I'll have room and power for gen2 modules if they materialize.
Plus they will run cooler. I might adjust the 4 module ductage if it is installed in 2 module units.

As mentioned above, ppl with UPS's surf through 'the beginning' of outages.
Luckily I have spare 1500VA's with new battery, prolly good for 5-10 minutes. lol

Don't forget about air filters!
I use furnace filter material for my PC's.
Huge filter so it can get a bit dirty and still have good airflow.
Clean is cooler

I'm thinking of making a duct for 20" box fans instead of the case fans.
A 20x20 furnace filter fits nicely on the input side.
My goal is huge air and lower noise with easy to replace inexpensive filters.
This will also remove a few watts from the rigs.
I point one at my PC's when I don't want to run the AC.
I also have my equipment on 2'x4' shelving with acoustic ceiling tiles under and around the equipment.
(tape or paint the edges else they are a major source of lint/dustage)
This helps lower vibration and noise.

My decorating motif is 'industrial', lol

Some people pimp their rigs with lighted fans, etc., not me!
Everything has too many useless LED's nowadays, fuck that noise.

Soon!
