Problem with Antminer S1

[lasmart613]

I bought two of them.  One of them causes the PSU to shut down if I power up both blades. 

I am using a 1000W PSU.  It runs the other S1 just fine.  If I power up either blade along with the good S1, it shuts down. 

I am able to run it in single blade mode, but with no other blades from either miner hooked up or it shuts down. 

I don't have a power meter or a DC ammeter that can check it. 

Any thoughts?

First thought is what brand power supply are you using? If your using a cheapo non name brand and even some name brands that could explain your problem. On the back is the psu rated power amps per circuit. I suggest you check that against the power draw of 2 s1's.

Yep, cheap & non-branded PSU is not recommended for S1. I wasted 2 -non branded- 500W PSUs months ago, then I bought Corsair CX500. Now they run great.
