I am helping a friend assemble his new computer (his first time building).
Components:
Amd ryzen 5 3600
Asus prime x570-p
16gb (8x2) gskill ripjaws ddr4 3200
Corsair tx650m
Msi rtx 2080 super
Samsung 970 evo m.2 ssd (1tb)
On the test bench (esd mat), we had the following problem. We turned on the power supply, motherboard rgb lights up. Bridged the pins for the power button (if looking top down on the pin set, upper left being number 1 and increasing left to right, we bridged pins 3 and 4). fans spin up for cpu cooler, power supply, and graphics card, but no output happens. We clear cmos, no change.
Our next thought was cou power. The psu has 8 pin built in, but the board is 8+4, and the psu doesnt come with a 4 pin connector. We went out and got one, plugged it in, turned on the psu. Motherboard lights come on. Bridge the pins, pau clicks, motherboard lights turn off, no fans spin. We tried the 4+4 pin cable in both of the psu's 8 pin slots, no change. We unplugged the built in 8 pin connector and tried the 4+4 in that slot, psu clicked, no fans.
What do we try next?
