PC DOESNT POWER UP!!

[Jiomaro]

I transfered my old motherboard from my acer aspire ax3200, into a brand new case, with a new psu. I tried everything but the pc doesnt power up? I can hear my psu making a beep but my case- and cpu fans arent running. Please help, i’m hopeless

Check your 24 pin connector. If it's not seated properly, you can brick your board. If that's the case, it won't power up. Second, try another PSU. If it works, it's the PSU that's bad.

EDIT: also verify that your power switch and reset switch are connected to the right header. Some boards (particularly the proprietary ones from dell) place them in weird configs.

Proprietary connectors?
