Asus WRX90 just shut down and now no power.
As the WRX80 manual never got corrected with normal pin out on its suggested motherboard PCIe connections, and this one has the second CPU 12V connection inb black for no explained reason in the maual I am checking here in case I should not have assumed that the CPU 12v and PCIe motherboard cables are standard and go in the usal places.
Can anyone point me to threads / parts of threads about troubleshooting ASUS WRX90 build? (oh now this smart pop up is helpful…>>>)
Asus WRX90Sage
7965wx (latest BIOS)
asetek 836S-M1A cooler -3 x enermax fans from the ill fated tr4 LiqFech
Super Flower 1600W platinum
Normal PSU cabling :
2 x regular CPU 12v to CPU12v(1)_1 and CPU12v(2)_1,
2 x regular PCIe cable to PCIE_8P(1)_PWR and PCIE_8P(2)_PWR
4x48GB Crucial compatible ECC DDR5 4800 RDIMM in correct slots, seated fully and recognised (finally)
PCIe5 M2 x2 (OS T705, Cache T700)
PCIE3 M2 x2 (Corsair mp500)
3090 founders - in second slot (because nvidia insist on putting ports right at the top where they get blocked by the case) slot supposed to be pcie5 x16x16
Decklink 8k pro slot 6 (x8)
RME AES card and Daughter Card. Slot 7,
Windows 11 pro volume licensed that was actually installed in previous TRX50 motherboard
on first boot I had to clear cmos and install the nvidia drivers again and it was determined to connect to one display only (had to unplug others to get it to display.
Will be annoyed if it has killed my PSU which was fine with the trx 50 and the wrx80
I will double check the jumper switches before I completely rebuild.
It is in a fractal Meshify XL with 3 noctua chromax A14 (in) front, 1 at the rear (out) and two fractal 140mm (in) the base.
I have seen the RAM overheats on these, but I had chrome on for an hour when it died.
Your power connections are correct. ATX_PWR, both CPU_12V, and optionally both PCIE_8P. Ignore the gray/black coloring - that’s to help you with a dual-PSU configuration.
no idea of the age of PSU but it should be fine. I have others I can switch out.
(Power supplies in computers are like inner tubes on bikes; severely needed updating design a hundred years ago. can’t believe I have to completely disconnect the motherboard and remove the psu to get to the connections)
I think the PMBus switch was set wrong, though there is no spatial reference in the manual. this one diagram is actually diagonal. in other switches in the manual left is down, so I think up is normal and down is PMBus
still doesn’t power up, just spins the fans for a millisecond
Superflower make some of the best PSUs recommended by system builders and overclockers so very weird that you have not heard of them. They also make PSU for other manufacturers, the EVGA Supernovas used to be made by them. I try to base my builds on Puget as I can’t get them in the UK (or afford them)
I don’t see how making one of the 12v CPU connectors black in the single psu diagram helps anyone; suspect it was just copied and pasted in from the 2 x psu diagram.
I didn’t know it was bad to use the clear CMOS when the machine was on. That was what solved this issue last time.
But clearing it when it was unplugged didn’t help. I could remove the battery and try again.
I have tried reseating all the connectors so the next step is to disassemble, remove PSU test it outside the box, test it with a different PSU.
Looks like a few people have had issues though with this board killing PSUs so I would rather not kill any others if possible.
I have also tried disabling BMC.
Seems odd that it did work.
I can see it could be something overheating so I will buy new paste and re seat the CPU. I do not know how old the HY510 paste I used was but perhaps it was long out of date. noctua tube ran out.
The AIO was installed correctly and it was not new. I just switched from TRX50 to get more RAM and m2 and pcie5 slots. wishing I hadn’t.
also wonder if I overtightened the AIO screws.
The colors in the diagram match the actual colors of the connectors on the board. (But I agree, the diagram ends up looking confusing.)
Edit: Some other thoughts I had. Since it’s only spinning the fans for a brief moment before shutting off again, it should be safe to rule out overheating. It’s just not running long enough for that to happen. Maybe the power supply’s overcurrent protection is tripping? If so, it’s possible there’s a short circuit somewhere. Make sure the motherboard standoffs are in the correct locations, all connectors are aligned correctly, and there aren’t any stray bits of conductive material in contact with the board.
It was the PSU.
Not sure if it’s fully dead or just stuck in some sort of protection mode.
I’m worried the board killed it.
1600w platinum should be ok with 7965wx and one 3090.
Rebuilt system, slowly, so wait and see.
