After about 10 mins the whole unit powered off and has been unresponsive ever since.
I've unplugged all outputs from the PSU and it's still not coming back up, so it looks to be the PSU.
Any ideas on what to try to resurrect? I have multiple CX750M PSU's but nothing big enough to replace the 1000W Enermax.
Cheers
I followed some advice earlier in the thread and removed one blade, it's now been mining for a couple of hours so far.
These batch 2 units are a lot quieter than batch 1, with larger effective fan diameters and case holes, they also seem subjectively cooler.
