5,1 Shutting down instead of sleeping

[bjar]

Hello all, my Mac Pro 5,1 is shutting down instead of sleeping. Not sure what the problem in. I have copied some of my system log from around the time it tried to sleep and then right after I booted it back up. info: 2 x x5677, 36 gb ram (from macsales), gtx 970, esata card, upgraded bluetooth and wifi. It is on a cyberpower PFC UPS if that makes a difference, although it worked perfectly a few weeks ago. I have done SMC and pram reset. Replaced the battery on the mobo. Unplugged all external devices. Anything else I should try? Note it does not randomly shut down, only when going to sleep, even when I choose sleep from the menu. Everything else is normal. Thanks.

Right before shutting down from system log:

I had the similar problem: it started with the same symptoms as yours but eventually got worse over the course of a couple weeks.

The final culprit was a failing power supply.

Bummer. I am thinking I will probably need to replace the psu as well.

PSU swap seems to have worked. Had it in for a week or so, no problems with sleeping now.

Good to hear! And hoping it lasts!
