Aurora R8, not powering up, no signs of life
Hello folks,
Hoping to get some troubleshooting help.
Just got back from a 2 day work trip, shut down my 2018 Aurora R8 before leaving, now it won't power back up. Ironically I do work in IT but the symptoms would tell me a dead PSU. Doing some research on here, it be a corrupted bios update.
Everything worked fine 2-3 days ago before I shut it down, now I can't even get the led light on the back of the PSU to light up. I have reseated the power cable at both ends, reseated my power strip( monitors on it do work still) and even reseated the power strip going into the UPS.
I have tried pushing in the reset switch on the back of the PSU, I have unplugged the power cable for 20-30 seconds while holding in the power button, then even plugged the cable back in, no luck. I have tried rapidly pushing in the power button 3-5 times. I have reset the CMOS battery.
I can tell there is a small surge of power going through the system by having a USB stick that lights up when powered... every 5-7 seconds it will blip for 1/4 of second the light on it. I've used to help me tell the power has been discharged when unplugged. Even through this, the led on the back of the PSU has never gone on. Anyone have any thoughts or something else to try?
Yes I have also tried turning it on with all USBs removed, I only left in the DP cables to my monitors since they are all through the GPU.
Thanks and looking forward to hear some more ideas from the community!

You can try a new CMOS battery, often makes things come back to life.
If not, either the PSU has failed or the BIOS has been corrupted. PSU would be the next most likely issue.
For PSU check you can try a BIST: BIST

@Vanadiel I've got some extra CR2032's lying to replace the CMOS.
Will check into the BIST while I update servers for a client in 20 minutes.

Well, don't have an extra Cr2032 that I can find but my battery tester does say poor life. More batteries on the way for tomorrow.
Regardless, BIST test shows no power to the LED.
Anyone know the PSU make/models? Else I'll pull it out to try and find a replacement.

@Joeblah Aurora R8 PSU is Standard ATX format, so many 3rd party options available. Consider a fully modular PSU that is no longer than 150mm. You current PSU is 140mm long. If you go longer than 150mm you will be encroaching on you cable management space.
This is an 850 watt fully modular Seasonic Focus that is 140mm long. Bring zip ties.
EDIT: OOPS . . . still no platform photo functionality; how special!![]()

Thanks, I actually found I misspoke and it's an R7.
Found the OEM part from Dell, granted they list 2 different parts specifically for my machine.
D460AM-03

Since the machine is well outside of warranty, going to give a $30 cheaper replacement a shot... that will get here tomorrow instead of 2 weeks from now from Dell.
Figured it would of been higher than a 460w for an i7 and 1080.

Late to respond but the PSU did somehow die since I shut it down. Replaced it, got the green LED on BIST test and booted back up.
