Systems check after PSU failure

[Semper]

System can be found in signature

So, the tl;dr is that the last week straight, life has shat upon me progressively more each day. I'm exhausted, frustrated, and grumpy. As such I know there's the potential for me to have overlooked things.
The week started with a succession of windows re-installation failures (windows itself had issues long before that I finally decided to resolve with a fresh install for my new chassis), largely because Windows update is wholly incompetent at it's single function. Some things happened throughout the week, and I'm currently looking at a $4k bill for vehicle repair as someone damaged my car in a parking lot and ran off, insurance left me out to dry. The week has now been rounded out yesterday with a PSU failure. I've got an RMA unit en-route from EVGA. My system is currently running off of an old unit I had tucked away. The failure was due to (at least as far as I was able to confirm with inspection) a resistor. She blew out the side and left a nice sliver-colored splatter across the PCB and wall of the shroud. All of this happening in a rebuild with a new chassis not even two weeks later.

I'm currently going through my system checking components. Would greatly appreciate someone double checking me.

Things I know are dead:
1x. HDD (In true Murphy's Law, the one that was the most full) [fails to spin up at all]
1x External HDD with on-site backup [produces a ticking sound and fails to spin up - was in the process of a backup during PSU failure]

1x Storage SSD [not recognized in BIOS, File Explorer or Disk Management - double checked sata/power connection, SATA port verified working with known good drive]

Things I suspect have issues:
Damaged boot SSD, or corrupt installation of windows. VERY sluggish. Takes several minutes to boot, Tasks within windows are unresponsive. chkdsk and SFC were both run; chkdsk returns no errors (assumed, as it completes and reboots into Windows), SFC fails and crashes powershell and command prompt.
Case-mounted fan controller (phanteks) does not appear to respond to PWM control (previously known to be working, fans appear to be running at 100%)

Things I believe to be functioning properly:
CPU (overclock appears to still be stable as well, no excessive overheating or instability though still needs to be tested on a new installation of Windows)
Memory (XMP profile still operating as intended)
All SATA ports appear to be functioning
All PCIe ports appear to be functioning (in addition to the GPU that was installed)
All front panel IO appears to be functioning
All rear IO appears to be functioning (including the USB port the external backup drive was using)
Visual inspection of the motherboard appears to show no superficially identifiable damage.
Peripherals appear to be functioning as intended.

Things I don't understand:
Why only one HDD and one SSD failed. All the HDD's in my system were on one power cable, all the SSD's (including boot drive) were on a separate one. Fan controller was plugged into the same cable as the SSD's

 

Anyone have any recommendations that I may have not thought of and/or glossed over. The help would be greatly appreciated!

Sorry to hear about your bad week, hope things look up for you soon. As to why only the one hdd and ssd failed I am not to sure but my best guess is that those two drives were pulling more power than the other drives on their power cable during the psu failure, causing them to receive the biggest spike of current hence killing those two drives in particular. As to the slow boot ssd try formatting and testing it for speed, if it is still slow than it probably has a few damaged components and i would not recommend storing any important data on it as it is most likely on its way out.

Lord I do as well. I'm ready for this week to be over, Thanks!

I had considered that, however both the drives that failed *should* have been idle, or as close to it as you can get. Nothing on either of the drives that failed are included in the backup (none of it is critical and outside of a screenshot or two I had saved, can't be recovered with a simple download), and at the time of failure, few processes would have been running off of either drive. Realtemp and Precision X1 off of the HDD, Steam (as in steam itself) off the SSD are the only ones that would have been running processes.

Yet another install of windows will be coming, but it's going to have to wait until I've got more time to dedicate to it. My "weekend" is on Monday/Tuesday and my time off work thus far has been spent just making sure hardware is functioning.
