Is Segotep gp1350, 80+ gold, 1250W, a good PSU for mining? If not, which is better?
The one that works is best,
Figure 80% utilization, keep them cooled, good air-flow
I find it better to BUY Two 750 CM's than to buy one 1500 CM, 2 750's are $100 each, the 1500 is like $400, each 750 can support a 3-1070's no problem, u can buy a cable for $1 that ties the two pwr-supply's together so they sync,
The only place I can see using a 1500 watt ( 1250w ) power supply is to power a BITMAIN antminer machine that requires special cableing
Pain in the ass to find 1500W gold supplys, easy to find 750CM (modular that 2-3 sets of 8pin gpu power)
More important that quality is running the thing below 75% utilization
More important is running your gpu's at 110 Watts, and NOT running them at 150watts, which kills everything,
Biggest problem in mining is most of the jackasses don't have a clue about hardware
Next to power is having plenty of external fans to blow clean cool air in, and over, and sideways
If your running a 1070-6 rig with two 750cm, that 3 gpus per supply at 330w, maybe mobo pulling 80 watts, your probably running at 60% utilization plenty of margin, these days even cheap ass chinese clone power supply have all the protection built-in
I like the 750CM supply's because they contain 4 8pin connectors, so you can run a BTC-12 MOBO and with 3 supply's and run 12 1070 cards off one rig, other wise a 2,000 watt supply would be +$1,000 USD

Another reason to run LINUX, windows only support 6/(
cards, linux u can do as u wish.
