Hey guys,
So I need your help. I have a new rig with an EVGA 850w PSU. After leaving the system idling over X-mas I walked into my studio (where it sits) only to see it's sitting at the Asus bios (I have an X99 Deluxe II board).
So, I reboot it only to get to the POST and load up the BIOS. It shows that only the CD-ROM is visible along with another SSD (I have 5 SSDs in this rig).
So suspecting a PSU issue, I open the case, and first make sure there's no loose connections or cables that may have slightly loosened... All good!
I then unplug all the PSU Sata leads (there's 3 of them) and systematically test my CD-ROM lead with each port, then each othe cable (which power the SSDs).
What I found was, if I have both PSU Sata's plugged in to my PSU, system boots up just fine, loads Windows 10 and business as usual.
However, if I have all 3 PSU Sata leads plugged in, it doesn't boot, goes to the BIOS and shows that only the CD-ROM is getting power, since I can't even detect any other SATA devices.
I highly doubt it's faulty cables or SATA controllers since this is a fairly high-end system and I chose quality parts since it's my work-station. Based on my somewhat limited computer-building knowledge it seems as though the PSU isn't supplying power equally to all the SATA leads when they're all plugged in, and if I only plug 2 in (out of the 3 total) it seems to function better.
My other theory is somehow it's not supplying enough power? Again, it's 850w so I thought it would be more than enough...
Don't hesitate to ask for more details, I am desperately trying to figure this out.
I've now successfully booted it (since I need to do work today) and I have my SATA PSU leads routed out of ports SATA 2 and SATA 3 on the PSU but am currently without a CD-ROM or front case fan (it's powered off the same PSU lead).
Theories?
