Solved Front panel power button won't turn on gaming desktop build.

Zalman Z9 u3 atx mid tower case

Specs: Windows 7 Professional, Intel Core i5-3570 3.4GHz / 8 gigs
Hi. I'm finishing up a gaming PC build currently. I have everything in the case, wires connected. It won't boot, but if I disconnect the front panel wires and short the power pins with a screw driver, the machine turns on, fans spinning, LED on, and the BIOS appears on the monitor, with all the parts I used labelled. I'm realizing that the front panel connectors are my main issue, and I tried wiring them the correct way according to the motherboard's manual. Any idea how this problem can be solved? The case I'm using is a Zalman Z9 U3 ATX Mid Tower.

Just in case, here's my other PC specs:
Intel Core i5-3570 CPU w/ Intel CPU cooler (I'm returning my Cooler Master Hyper 212 EVO because the nuts from the platform that goes under the motherboard touches the case)
ASUS P8-Z77-V LE Plus motherboard
Corsair 8GB RAM
EVGA GTX 660 TI GPU
Western Digital Black 1TB HDD
Crucial 128GB SSD
NZXT 650W PSU

"I tried wiring them the correct way according to the motherboard's manual"

The power button is nothing more than a momentary switch, similar to a doorbell button. There is no polarity so it doesn't matter how its wires are connected, but they MUST be connected to the correct 2 pins. You must be doing something wrong.

I did connect them to the correct 2 pins, but the power button still doesn't work. Same happens with the power button LED. The reset button and HDD LED work though.

I heard of a pin header ASUS makes, where the front panel wires connect to the male end, and the female end goes right onto the header on the motherboard. I might look into using that, but could there be any other possible reason as to why the power button isn't working?

✔ Best Answer
If you're sure they're connected right then maybe it's the switch or wires. Attach the leads coming from the front panel to an ohmmeter or continuity tester. Then push and hold down the on/off button. The meter should show a short if they're good.

I've done a continuity test on the power button wires. There's no connection, which proves that the wires or the connection between the wires and button are broken. Perhaps part of the button itself is broken. A source said that most PC case buttons are made of plastic, which means they're most-likely gonna break. I was careful with the wires when I did the wiring. My best option to solve this problem will be to solder a switch and wire it to the power switch pins on the motherboard so I can easily turn on the system just by having the wires coming out of the system. It's pretty meaningless to just replace the case all over the power button because the button itself is plastic and could get damaged in any way. If this option I came up with works, then this problem will be marked as solved. Thanks for the advice.

" turn on the system just by having the wires coming out of the system."
this just doesnt sound like a good idea. I'm wondering if static electricity could be a problem over time.

I dont think this is a common problem, you just got unlucky.

The wires can be covered up in the same plastic material USB cables use. It's pretty simple to protect the wires from static electricity. Also using electric tape too.

And I agree that I got unlucky. I still find it simple to put in a new switch, unless I can actually get into the front panel and fix it. But the case's manual doesn't describe how to take the front cover off. I would have to search up on how to open the front panel.

Hey, I finally figured out that my power button wasn't connected to the wires that go to the power switch and power LED pins. It works now. Problem solved!

It's odd the case would have come that way. Well, we're glad you got it fixed.
