New Computer Build - Not Working
New Computer Build - Not Working
Hello everyone celebrating the new year!
For Christmas, I put together a fresh setup for myself.
ASUS Prime X670E-Pro WiFi motherboard
AMD Ryzen 9 79003D 12 Core 24 Thread CPU
ASUS TUF Gaming GeForce RTX4070Ti OC 12GB GDDR6x GPU
WD Black SN770 2TB PCIe Gen4 NVMe M.2 SSD
Corsair Vengence 64GB DDR5 5600MHz RAM
DeepCool LS720 High Performance 360mm CPU Liquid Cooler
Phanteks Eclipse G360 Air Mid Tower Case
ThermalTake Toughpower GF3 1000W 80+ Gold Full Modular ATX Power Supply
I’m facing a few issues, some more pressing than others.
Powering on or off the system isn’t working through the case switch. The only way to start it is via the motherboard control, and shutting it down means turning off the power supply.
I’m struggling to locate where the power switch cable connects to the board. The label says Power SW, but one wire has a white strip. No other details on the connector. I’ve tested all possible setups, yet nothing works. I’m uncertain if the cable is meant for two pins side by side or two pins stacked vertically. The manual doesn’t clarify much. I’ll send a picture if it helps.
One combination seems impossible because the board lacks a pin. I’m not sure if that’s intentional. My guess is the pins labeled PWRBTN# and GRD (the white striped wire). But that doesn’t seem right.
Unless I’m missing the correct chassis button, there are two buttons I don’t recognize: one with a circle and another with a thick broken circle.
The front fans aren’t spinning. Is that intentional? Perhaps they activate only when needed. There were three cables to connect—each to a separate CHA FAN connector (1, 2, and 4).
Most importantly, I’m not seeing any display on my monitor when the system powers up. It’s lit up like a Christmas tree—lights are on, the GPU is active, and there’s a steady red light next to the power connector, suggesting it’s receiving power. I tried connecting via the built-in graphics port, but nothing happened.
When the power is off, I’ve reattached everything, but the SSD, RAM, and display still don’t work. I can’t seem to free the graphics card without forcing it out. Does it have a release clip like the RAM? I just manage to pull one end free.
I own a wired USB mouse but only a wireless keyboard. Do I need a wired keyboard?
Edit: I wasn’t able to capture a clear photo of the motherboard. I couldn’t get close enough, so I attached the manual image instead.
Begin by unwinding and working only when fully alert, allowing each step to be considered without haste. Review all manuals to ensure nothing is overlooked. The GPU features a clip securing it to the board at the end of the computer, located on top inside the case. Gently shift it sideways and slowly lift it out. I use the same card, which is large and heavy, so proceed carefully to avoid it dangling in multiple places.
Consider building everything on your desktop using a big piece of cardboard as a base, without the case at first. If all components function correctly, it might indicate a short in the assembled case or damaged wiring between the front panel and connector—often due to a faulty wire. AIO coolers complicate the process slightly (keep the radiator above the CPU).
Avoid adding unnecessary items initially, such as the GPU or a single stick of memory. Also, a quick note: what is your complete memory model number?
Hi RealBeast.
I kind have made some progress with problem 1. There is a button on the front of the case (I thought it was just part of the design). I can turn it on but not off. Even if I hold the button down, it doesn't turn off.
Is this the memory model #? CMK64GX5M2B5600C40
Will start over tomorrow fresh, getting late now. I'll have to see if I can figure out how to remove the grpahics card.
One thing I will say, I was not impressed with the limited cable running between the MB and th epower supply. The power cable for the MB is a bit too short to run the only way to run it so things are really pulled tight. My only negative so far (and the fans not working - when you power the system up they get a boost of power and "jolt" themselves ... not spin though.)
Beginning anew this morning by taking everything out and putting them back individually. Using the motherboard graphics, what minimum would be required to make the computer display and post? Would a single stick of RAM suffice, or would I also need the SSD? Also, do I need a wired keyboard to start, or will a wireless one be detected before the OS is installed?
Attached is an image illustrating the connection of the Power SW cable. The white line connects to GND.
None of the front chassis fans are running at the moment. It seems they might not be properly connected to the motherboard, so the CHA FAN connector should work. I don’t have a manual for the case.
Yes, it required some clever adjustments to get it working. The radiator is positioned on the outside of the cabinet at the top. Everything looks fine now, lights are on and fans are running.
I'm feeling a bit anxious. I've taken out all parts except the CPU and cooler. I've replaced one memory module at a time according to the manual's suggested port, testing each without any issues. The SSD was removed. No success. All without the GPU installed.
Front fans aren't working, and the power switch isn't turning off. It's like searching for something in a huge haystack.
I have this unidentified connector left over. I'm not sure if it matters since I can't find any instructions on the manual to connect it.
Remove all the wires from the front panel of the board. Using a screwdriver, gently touch the two pins labeled power switch in the manual with the end of the screwdriver. If everything functions correctly, it should activate. This method effectively bypasses the switch on the case.
If you continue to experience issues, take the board out and place it inside the motherboard box. Connect only the CPU power, motherboard power, cooler, and RAM, then try using the screwdriver approach again.
If this works, proceed by adding one component at a time carefully, even the GPU, and ensure each part is in good condition.
If successful, verify all your internal connections inside the case to prevent any accidental shorts.
For my experience, when wiring the case to the front panel, you’ll usually see a small black arrow on the connector side with no label. It’s very faint and is often used as the positive connection.
Display an image of your setup to verify the connections. Where is the source of this information?
Hi Ohio_Buckeye. Thank you for your response. To be clear, I can power on the computer using the switch, but not turn it off. Does your advice assist in identifying why it can't be switched off?
I'm primarily worried about the monitor not connecting to my display through the onboard graphics. My monitor uses digital video and has an adapter between it and the HDMI port. Could this be the problem?
I spent some time organizing the cables from the chassis, which were a bit disorganized. I separated them into several groups: one for the USB3.2Gen1 header, another for the HD Audio, a Power SW cable, SATA power, and a few smaller wires with 4-pin connectors that likely correspond to the front fans. These wires are connected in a chain, with two ends left open. One end resembles another fan connector, which is hard to locate now, while the third is male and possibly for future lighting expansion. I'm unsure if I need to work on anything else with these wires.
I'm quite cautious about taking everything apart. The cooler was tricky to install, and I worry that any rough handling could cause damage. All nine motherboard standoffs are present and correctly positioned.
Skynet, this note might help clarify the issue with the unconnected connector. It seems part of the daisy-chained setup. I'll try to capture a photo.
Can you disable it by pressing the button? Another method involved connecting the reset button to the power pins so it functions as a power switch. It might be worth trying.
