What motherboard, GPU waterblock, water pump and PSU (try be more specific)
■ Slot, try borrow PCIE card and instate it on the slot to see if it work, during leakage test, did you notice any leak sip onto PCIE slot?
■ PSU and water pump, some pump use up to 25 watt (typical D5 setting 5 or 100% PWM) try different molex or 4 pin connector and connect directly to PSU (if you now connect pump to motherboard's pump header).
■ Try not to use stock cooler or waterblock, quickly enter BIOS to see if your strix detected, if it does then just shut down, if it not then you should contact ASUS and ask why your GTX 1080 Strix is not switch on when not plugged to its own fan header!
FYI had the exact problem with directCU cooler and ASUS CS replied was not pertinent to my question.
For the waterblocks im using EK for both my GPU and CPU and my motherboard is the EVGA Z170 Classified K, PSU is EVGA SuperNOVA 1000 PS
- as for the leak there were none
- ill try using a different molex and 4 pin but my pump works good
-the thing is i took off my waterblock to see if my motherboard would see it and while the stock was on i had plug all the cords in and the fans were not working on for a few secs but ill try to see if it see it without a block on it
