The title basically says it all, it worked just fine yesterday until i moved my pc to the other side of my room because i had a room makeover or however you call it. Anyhow i noticed when plugging in the 20 + 4 pin connector halfway in ( not really plugging it in just putting it in there) my pc starts for like half a second since i can see my front panel fan lighting up and spins like 180 degrees until turning off, same with my water cooler fan. I don't know how to fix this since it worked just fine yesterday. My PSU is an AXP with 630 watt model number AXP-630P12P and sorry but i can't really tell what mobo i have since i can't turn on my pc but it is a Gigabyte mobo and it say's ht30 am3 to the right of the cpu.

Did you plug in the 4 pin(depending on your motherboard it may have up to 8 pins) power supply on the motherboard.

If you're talking about the 20 + 4 pin then yes i plugged in them both but it won't work then as it used to, i only get power for like half a second if i "plug" it in like 1/3 of fully plugging it in. (I'm browsing the forums with my phone as i have no other computer)

Sorry to bother you with this question, but what is "shortening" cables and how do i do that? This is the first time ever i own a desktop so i hope you understand my inexperience.

Just found out what you were talking about, it looks way too complicated. And i don't think i'll manage without breaking anything.

Dont worry bro everyone was a beginner once.

ITS NOT COMPLICATED AT ALL.ILL TELL YOU WHAT TO DO
1.unplug the 20+4 pin from your motherboard
2.You will see a green wire after taking a closer look
3.Now take a small wire and plug it into the green wire's socket
4.now connect the other end to any black wire on the 20+4 pin
5.Your psu should now turn on,you will notice the fan spinning.
6.If it does so your PSU is fine and something might be wrong with the motherboard

go here if you still dont understand

Yeah it seems easy enough, but do i need to have the 8-pin connected to the motherboard for this to work or should i have none of the power connectors connected to the motherboard?

Just got myself a new motherboard and i get exactly the same problem as before. I found out that there's a problem with the 20+4 power pin, i got my pc to start for a few minutes when i only plugged the 20 pin in halfway extremelly carefully or else it would turn off. Anyways when i had the pc turned on i didn't get any picture and i was unable to turn my pc off via the power button. So i'm gonna return the motherboard tomorrow and buy myself a new PSU so my problem finally will be solved.
