kilo17,
Looks really cool. I wish I waited a few days before ordering a whole bunch of 2000W PSUs and fans.
Your investment is safe. Per S7 wise, the 2000W PSU bundle is still the best bang for the buck with no mods required. Quiet as a whistle with the Ultra KAZE fans. The fact that you can add voltage changing abilities is just extra bonus on top. I may get 1 x 2980 to play with it in the future but most of my purchases are still leaning toward the 4K bundle with the 2x 2KW IBM PSU until the 2980 becomes more affordable.
if you do 6 or 12 or more s7's
the 2980 with kilo17's mod is most likely the way to go.
And only if the 2980 gets much better efficiency.
my testing shows the dual 2000 = 4000 is better power use then the 2880watt.
this has been with 2 avalon sixes
one reason for this is the dual 2000 uses 2 .6amp fans total of 24-26 watts
the 2880 uses 3 1.68 amps fans total of 59-61 watts .
one runs at 9.2 amps = 0.3247 watts a gh---dual 2000
the other at 9.3 amps = 0.3282 watts a gh---- 2880
While doing 6800gh all estimates from memory.
kilo17's mod is huge for every 6 s-7's using 3 2880watt psu's
you save 150-160 watts 24/7/365 about 150usd a year
I ORDERED 2 FANS FOR MORE TESTING.
I ALSO think his fan mod will work for the dual 2000. which is why I ordered 2
