Topic: Issues shorting EVGA Supernova NEX750B (Read 3515 times)

found this late.  the issue with that psu is multi 12 volt rails .  it runs 1 s-3 only due to the multi- rails and you need to plug in the right amount of pcie cables.

see here at newegg it has 4 rails

I may have found a solution, for my situation at least.
If I plug all 4 12V+ rails of the supernova into the Antminer, the psu tester WORKS.  *been on for 2 hours now *crosses fingers**
Since I was never planning on using the supernova on more than one antminer, my issue is resolved (as long as it stays on).

However, if someone else wanted to use the supernova to power more than one antminer, I'm not sure how they would do it with this PSU.
Or if they wanted to power an S1, it would not work for that either.

Yea, that was my original thought until I tried one of my Corsair psu's with it, and it worked perfectly. The Corsair PSU in my original post is running with another identical PSU tester.

Tester's are a standard for shorting PSU's to use with miner's. You can see them in a lot of the pictures of big farms. Mainly cause you can get them for 2-3 bucks. If a psu tester turned off after a short amount of time it would defeat the purpose of the psu tester. It would also require more logic, and therefore more cost, and therefore a smaller fiscal bottom line.

Have you used tester on another PSU to see what it does?  I have not used a tester to short it would make sense if after a certain amount of time it does power off.

Are you sure you are making contact to both pins when shorting?  First check spot as it could be bad if not in correct holes.  But if you make contact it should be the same as if a switch is used.   

Attempting to run my Antminer S3 with an EVGA Supernova NEX750B. Its modular. PSU won't stay on.

When Supernova is not connected to Antminer  (2 of the 4)
- psu tester WORKs when MB cable is plugged into tester. *was on for an hour before I turned it off*

When Supernova is connected to the Antminer (2 of the 4) AND Corsair is connected to same Antminer (2 of the 4)
- psu tester WORKS when MB cable is plugged into tester.

When Supernova is connected to Antminer  (2 of the 4)
- Green pin to ground doesnt work. **Miner powers on, hits 440 hasrate, PSU cuts out, rough time on ~30secs - 1 min**
- psu tester doesn't work when MB cable is plugged into tester. **Miner powers on, hits 440 hasrate, PSU cuts out, rough time on ~30secs - 1 min**
- psu tester doesn't work when MB cable, & cpu cable is plugged into tester. **Miner powers on, hits 440 hasrate, PSU cuts out, rough time on ~30secs - 1 min**
- psu tester doesn't work when MB cable, cpu cable, & sata cable is plugged into tester. **Miner powers on, hits 440 hasrate, PSU cuts out, rough time on ~30secs - 1 min**
- psu tester doesn't work when MB cable, cpu cable, 5V fan/hdd power cable, & sata cable is plugged into tester. **PSU starts, then immediately cuts out, on for maybe 2 secs**
- Just bought Bitmain Antminer Jumper Switch and will test with that

Outside of using the Antminer Jumper switch as I'm already *going* to do that, any suggestions?

** EDIT **
plugging all 4 12V rails into the Antminer, WORKS with the psu tester. (been on for 2 hours so far *crosses fingers*)
