    Mid-2010 Mac Pro power issues
    Hi,

    I have a mid-2010 Mac Pro 8-core that I got from a friend today. I picked it up at 3:00PM-ish, powered it on at 3:30-4PM, and then turned it off and went to work for 5:30PM. I just got home about two hours ago and went to go turn it on. The power button does nothing; no lights, no sounds, nothing. When I press the DIAG button, the yellow/amber LED comes on and shows the PSU trickle power is fine (5V STBY). My Mac Pro doesn't have an SMC_RST button near the DIAG LED button like some manuals say... is this normal? I've tried every possible trick/advice I could find online that didn't require me to press key combinations at startup (because it won't turn on). Any suggestions would be greatly appreciated.

    It sounds like it needs a new PRAM battery?

    That little coin battery could cause this many problems? I ordered a power supply on Ebay today (same part number, from another Mac Pro) and I'm gonna try that out and if that doesn't solve the problem I'll return it because I made sure it had a 30-day return. My gut feeling is telling me that it's the power supply. I'll snag a new coin battery from the store tomorrow when I'm out running errands and put the PSU back in.

    If the PSU isn't the issue, I might still keep it so I have a spare just in case that IS an issue in the future.

    I probably shouldn't have jumped the gun and spent over $100 on a PSU, but we live and learn.

    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    Just got back about an hour ago, and I tried putting the PSU back in and replaced the PRAM battery - no avail. Ebay says the new PSU will be here by Friday. Fingers crossed!

    On another note, I'm going to be upgrading the RAM, HDD setup, Graphics card, and the CPU tray. The changes I'm making are getting the 8-core Xeon setup, 32GB of RAM, an AMD Sapphire RX580 8GB, a 256GB SSD for the boot drive and a secondary 1TB Seagate Barracuda for storage. I just need to get over this power supply hurdle!!

    I'm not a betting guy.... but it's a good bet the new PS gets you back up running again. Mac Pros love to go through Power Supplies, we get threads all the time with that same problem. Keep in mind your Pro is going on 8 years old.

    I hope so! I love this computer very much, and I will take good care of it. I don't mind spending the money on an 8 y/o computer because if something goes wrong, I know how to work on it and plus, this thing is pretty much futureproof with the 12-core capabilities and up to 128GB of ram.

    Thank you for your insight!! It makes me feel more at ease.
