Is PSU too weak for my build? 5960X w/ 4x8GB 3200 and 1000W

[CaneHorn]

Build was completed in Dec 15 and worked flawlessly. System designed for overclocking obviously but has only been rarely pushed using the external OC controller but generally running on default optimized bios settings.

About a week ago, it started shutting down randomly and rebooting itself sometimes, other times would stay off and require a manual power on and yet other times, not accept the manual power on until master power off and set alone for an hour or more.

Just before problem started, I added Corsair platinum fans to my RAM. I bought a 4x8 set that only had one fan so finally bought and installed both when I bought the additional fan unit.

I've checked the cables and reseated things. Reset CMOS and bios. Got problem to go away for a few days, then it came back today. Same inconsistent behavior. Restarted itself the first shut down, I manually restarted it the next shutdown a couple hours later, now it has been off for about 4 hours and is unresponsive.

Here are my system specs:

Motherboard:
Rampage V Extreme/3.1
Processor:
i7 5960X
Memory (part number):
Corsair Dominator Platinum DDR4-3200 CMD32GX4M4B3200C16
Graphics Card #1:

Sound Card:
Creative xifi titanium platinum
Monitor:
Dell 30" IPS
Storage #1:
OCZ Vertex 4 SSD 256GB
Storage #2:
5TB of hardrives
CPU Cooler:
XSPC D5/RX360
Case:
Lian Li V2120B Tower
Power Supply:
Seasonic Platinum 1000w
Keyboard:
Razer Tarantula
Mouse:
Logitech G502
Headset:
Logitech G330
Headset/Speakers:
Logitech 5.1 THX
Windows 10 Pro x64

Is it possible the 2 RAM fans pushed me over the PSU's power capability? 1000w should be enough without SLI shouldn't it? Start replacing cables or other thoughts?

Since I'm not superclocking this...yet...I will in future but don't need it yet since such a jump from old PC....I haven't bothered loading up all the ASUS software. Is there one or more I should install to diagnose my issue or repair? Seems like ya'll mostly using 3rd party memtest and such.

Thanks in advance. CPU temp on OC display until never shows overheat so don't think that is the issue. Usually low 30c range when pushed hard (photo editing, gaming, optimization solves.)

There is an Intel processor diagnostic tool....google stress app test for memory....RealBench for system stability....

Have you had a look in windows event viewer to see if anything shows in there? it sounds more like a kernel power 41 error. my pc about a week ago started to do the same thing it was an kernel power 41 (63) doing it. to fix it i had to uninstall all the audio driver and redo them all. seems to have fix it for me. hope it will work for you and that its not hardware.

Thanks for the diagnostics recommendations. I want to stay away from ones the beat up my SSD so those device specific ones sound perfect.

Interesting on the kernel finding. Yes, I show that same error but the message seems to indicate that is from the shutdown, not necessarily causing it? What led you to the audio drivers? May I ask what audio card/drivers you are talking about? I have the onboard audio disabled in device manager and use creative drivers for my xifi card. Machine has been stable for a couple days now but if it acts up again, I'll reinstall creative drivers. I don't load all their apps, just the drivers. Even though disabled, should I also install audio updates from ASUS? Thanks!

No only install drivers for hardware that is active

Well, after 6 days of stable bliss, the problem returned yesterday and continues sporadically. It passes memtest but intel cpu test doesn't run (.net framework error and I have latest install) and realbench crashes on the 3rd set of tests. I was watching cpu temps and it did spike at 80 during the 2nd tests but quickly came back down and was in the 40's when system shut down. I'll try to run it again when system revives.
I did also reinstall latest creative drivers but the last crash happened after that so no joy there. Beyond frustrating! Also fixed an error i found on windows log for bad ethernet issue but problem recurred after that fix as well.
