If i unplug the 6 pin cables to the GPU. every fan will spin but no POST.
1 hour ago, nido2 said:Hello everyone, its my very first time building a computer so please do tell me if im doing anything wrong. ;-;
Spec:
CPU: AMD Ryzen 5 1600
Motherboard : ASUS prime B350M-A
RAM: corsair vengeance lpx ddr4 (8gb X2)
GPU: GTX 1660 Super
CPU cooler: included cooler with the CPU
PSU: First player Full modular 500W 80 plus bronze
SSD: random SSD brand 516gb (new)
*all of the stuff i have here is used.
Troubleshooting steps that i have tried:
(1) Unplugging the GPU and turning on the system
-after powering on the system, every fan will spin but no POST(as expected cuz i dont have an igpu)-motherboard shows a static orange light
(2)Swapping ram with a new ram
-swapped with a brand new ram, still will not power on with the gpu plugged in.
-without the gpu plugged in, the fans will spin and shows a static orange light.(3)Install the GPU into the motherboard but without the six pin connector
-all the fans spins (even the GPU's fan), but no POST on the monitor
bought a new plastic back bracket for the cooler as it is missing from the time i bought the motherboard.(when installing the cpu cooler, the board flexes a little bit, idk if this is normal or not)
**The monitor is working as i use the monitor with a laptop and it works
What might be the problem? i am supposed to have enough Power from the PSU but is the GPU faulty?
Confirm that you are not connecting the monitor to the motherboard instead of the GPU.
I am assuming that when you say won't power on, there is no sign of life on the PC. No lights, or fan spin.
I am also assuming that you've done the basics of troubleshooting as other posters has said:
- Clear CMOS
- Reseat GPU / Test GPU in another system
- Verify RAM is on QVL
I would suggest that you test the parts outside of the case. Do as you did before with testing the parts. CPU + motherboard + Cooler + 1 stick of Ram + GPU. The motherboard should preferable be on the motherboard box when testing and not on anything that conducts electricity. Connect the PSU to it using the appropriate cables making sure they are correct. Connect your display to the GPU. Then turn on the system using a screwdriver to bridge 2 pins. You can locate the pins using the motherboard manual on page 12 (1-4), Number 8 - Atx Power Button pins.

I'm not sure whether its the camera but there does appear to be some slight curvature at the top, I am going to assume that's from the 3rd party CPU mounting bracket. Try loosening the screws on the cooler a bit to reduce the board flex. Can you take a picture of your standoffs in the case when the motherboard is not present as well. I want to rule out the possibility of a short from a standoff in the wrong location.
Given that your system doesn't turn on at all with the GPU installed + the PCI-E 8 pin power plugged in. I would suspect a short. The orange light is an indicator of power if I'm not mistaken. If that is not on or goes out when you plug in the GPU power cable then I would replace that cable as it is either not meant for that PSU or is not the right type. OR it means you have a faulty GPU. It is unlikely the GPU will be faulty given that you have fan spin.
EDIT: The orange lighting is referring to the RGB/Board lighting. Not status LEDS. Still a good enough indicator of power and worth checking the above.
To summarise, I would do the following:
- Rebuild the system outside the case.
- Check that the Power cable going to the GPU is correctly labelled as PCIE or if there is a spare one, to swap it to that and test.
- Test with another PSU if that fails to work.
- Maybe loosen the Cooler a bit so the board isn't flexing/bending as much if it is.
- If the above doesn't help then I would try with a different GPU.
At the very least I would except the system to display a message stating that the GPU power has not been plugged in if the power cable is disconnected.
