Morning

One of my mines seems to reboot when I fire up the fourth GPU. Last night I was tinkering for hours and managed to get it going with 3 cards but woke up this morning to find it had rebooted yet again.

It's not a blue screen, just goes black then reboots into Windows. I've tried swapping the cards around, same results. I am thinking it could be the PSU?

Intel Celeron 2.7Ghz
AsRock H61 Pro BTC Motherboard
8GB TeamGroup Memory
4 x R9 280X
Antec 1300W Platinum PSU

I have 5 other rigs all identical but had no similar problems.

Help is much appreciated as always :)
 
Tried swapping the PSU's round? Looking at your build log that shouldn't be too difficult & impede on your mining operation too much.
 
Haven't tried swapping PSU, no. Though good idea. It shouldn't be too much trouble at all given they're all the same.

Will do that this afternoon.
 
Just tested - the same PSU in another 100% identical machine causes a reboot when the fourth card is turned on.

RMA here I come!
