No power

[ZenMonkey]

I was running an ITX build, but front panel on my old case stopped working. I didn't like the heat of a SFF gaming rig, so I bought a new case and motherboard (Phanteks Eclipse P400S and ASRock Fatal1ty Gaming Z97X). Everything else was working, so I transferred everything into the new case and motherboard last night. When I push the power switch, nothing happens. There's no power at all. I disconnected the 24 pin and 8 pin ATX power cables to the motherboard and reseated them, but that didn't fix it.

 

I don't have a voltmeter, but the power supply was working fine three days ago. What are some steps I can try before I resort to completely disassembling and reassembling the computer?

 

Also, the P400S front panel connectors had a SATA power connector, but the panel just two USB 3.0 and a the audio in/out 3.5mm slots, the power/reset button, and a fan controller button. It looks like it's connected to a daisy chain of fan connectors to power the front fans and fan controller button, but I'm not 100% certain. I plugged it into one of my SATA power cables, which only has one 3.5" drive attached to it. Can SATA power case fans? I checked the user manual but couldn't find an answer. Anyone familiar with this case that can elucidate for me?

Sata connector is for the fans

Try to short the two power switch pins on the mono with a screwdriver they are with the front panel connectors

the SATA power connection from the PSU is for the RGB lighting

Check that the front panel connections are correct, and try shorting the power button pins together to turn the pc on. Make sure psu main power switch is on. Make sure there is no crap in the 24pin connector.

 

Sata is commonly used to power fan controllers.

I was able to get it working. Thanks for the help.
