Question Brand new build - No Power

[asif2005]

I built my PC and was getting ready to turn it on for the first time with Win11 USB ready and plugged in. I turn it on and NO POWER. no LED, No light, no flashing indicator, no beep whatsoever.

I disconnected everything (including RAM, SSDs, etc.) except for CPU Power and ATX 24-PIN. Still No Power whatsoever. The Mobo has two CPU power connections, I have mine connected to the first one. The ATX Power is secure the latch.


Motherboard: MSI MPG Z7900 Edge Wifi (Brand New)
CPU: Intel i7 12700K (Brand New)
PSU: Thermaltake GF1 850 (Brand New)

What should be my next steps?

I am really bummed out right now. I have already had to RMA my original Gigabyte mobo because it had damaged CPU socket.

Please advise.

You could buy a power supply tester, or digital multimeter. Probable available at many local stores. The multimeter would have other uses than just this test, so it wouldn't be wasted money. Use this site to know where to measure voltages: https://www.smpspowersupply.com/connectors-pinouts.html

I did a JFP1 short and the computer came on. I plugged the power switch connector back on and computer turned on. The power switch cable properly plugged in so I don't know what manual short did. But things are looking good and I just finished installing Win11.

its possible you had the positive and negative backwards on those pins ive done it myself and not had the pc turn on.

there isnt a standard for that jfp1 connector so the power and reset can be on different pins which is why the manual is needed lol.
