Hi all -

I have 2 S2's -- purchased just 2 weeks apart - back in early June .
The first ordered S2 antminer (order # 00120140617210324211R5oX3cPM0667)  has suddenly stopped working -- it will turn on, but then turn off after about 5 minutes.

I have opened it up, disconnected the PSU - let cool off for 3 days then tried again. - turns on for 5 minutes then completed turns off, no power at all.  The 10 blades don't even turn on (no blue light on chip boards) during the initial 5 minutes. -- So, I think I might need a new PSU but then again it could be the mother board. - or is it just a simple PSU issue?

BITMAIN has been contacted THREE TIMES and has NOT gotten back to me -- I'm out almost $1800.00 here ---

Has anyone has any luck with other PSU's? -- if so which ones? - and I noticed there are 2 PCI-E connectors and 2 twelve pin connectors (NOT The standard 10). These last two connectors are the hard ones to fit. 

Any advice would be appreciated -- thank you --
