thanks for the reply yeah, i always plug everything in tightly thanks for the reply well, yeah, of course i am. i may be stupid, but even i am not that stupid.

My EVGA 500 BR PSU's 4x2 CPU cable seems to shut down my motherboard. When it isn't plugged in, pc powers on and stays on. When it is plugged in, pc powers on and then off.

I already posted a month or so back about my problems and during the time between this and that, I have made absolutely 0 progress. My build real quick: MOBO: Gigabyte H310M-A CPU: Intel i3-8100 GPU or Video Card: ASRock RX 570 4GB RAM: DDR4 8GB Storage: 480 GB SSD + 1TB HDD PSU: EVGA 500W 80+Bronze My atx_12v pin was my previous thread's topic. I had a hunch, a suspicion that the suspect was that particular pin. The computer turned on with or without the atx plugged in. The only difference being that with it plugged in it would turn off in 10 seconds or so, while without it plugged in, everything turned on and stayed turned on. I scoured around the first page of google for a while and came across this thread: https://www.computing.net/answers/hardware/my-computer-wont-boot-up/94159.html... It's my first build. Is there any... suspect? What could be making it not work?

There is one standoff missing, but I don't really think that's the problem... hmmm....

That part I know is connected successfully, since I always hear a click when I put it in perfectly. When the latch is facing a different way, it either doesn't click or get put in at all. It says the 12v mainly supplies power to the CPU. If the 12V power connector is not connected,the computer will not start. Seens the opposite to me, though. The 24pin is necessary, since I think it sends power to all the other parts. The 12v pin is... confusing. It doesn't look like I need it, to be honest, but I've read all across the internet that the CPU doesn't work without that plugged in. That was the reason for this thread being created in the first place.

When the ATX_12v pin isn't connected, everything works perfectly. No shut down or anything. Yeah, it's plenty wack. I talked to my cousin who built his own pc, told me to get a new psu or a mobo so I can connect all 8 pins. All screws and standoff are fit in snugly. I, like, took everything out and put it back in at least 4 times already.

I have a 100v and a 240v option. 100v is like the off switch of the psu. 240v is the only option that works. thanks for the reply. yee

No, my psu's non-modular. It's new as well, so I don't believe that's the problem...

The system fan and cpu fan starts up normally for around 10 seconds with the psu's cpu cable plugged in into the mobo's 4pin atx 12v pin but it shuts down immediately with a weird noise. My GPU is also weird. It has a PCI-Express pin but doesn't need it to start. It feels like I did everything wrong. specs: i3-8100 8GB DDR4 RAM ASRock 4GB DDR5 RX 570 GIGABYTE H310M-A 480GB SSD + 1TB HDD EVGA 500W BR 80+Bronze

My specs aren't all that impressive, but it is what it is. FYI: USD. CPU: Intel i3-8100 ($115) MOBO: H310M A ($59.99) RAM: Patriot 4GBx2 ($37.99) PSU: EVGA 80+B 500W ($37.19) GPU: ASRock PG RX 570 4GB ($129.99) CASE: CoolerMaster Q300L mATX ($49.98) STORAGE: Kingstone 480GB SSD ($54.99) + BarraCuda 1TB 54k RPM ($33.68) -- $519 Honestly, it's pretty whack. You could get a smaller SSD and maybe 16GB ram.
