Pulled PSU cable - PSU won't work

I was just an inch from reaching the CPU power cable, so I pulled on the cable slightly from the PSU.

Now, after all the cable management, I try to turn the rig on.. and nothing.

There is this super-tiny noise that comes out of the PSU whenever I try to turn it on, but that's it.

So, I open it up and I see that the cables inside have tipped over some capacitators.

It's like a big mess of cables and capacitators and I can't see inside it.

I balanced the capacitators, but that doesn't do the trick.

What do I do do now?
 
You mean that the fans don't start and the hard drives/optical drives don't even spin up? In other words, the motherboard isn't even getting any power at all, besides the standby power (e.g., green light on the motherboard, etc)?

Are you sure you plugged in BOTH of the ATX12v connectors ? (the 20 and 4 pin, if applicable?) as well as the two modular connectors going to the PSU?

Yes, that is exactly it.

I un-plugged and re-plugged the 20+4-pin connectors.

Why do the modular connectors matter? Since it doesn't even start up, it has to be a motherboard 24-pin connector problem at the very least.

I am thinking that either the connectors on the PSU end are damaged, or some of the capacitators are broken.

Unfortunately, it's like a forest of cables and capacitators in there. There is no way I can re-solder anything.

There are 2 connections you need to make. The 20/24 pin main connection to the motherboard and the 4/8pin connection near the CPU socket. He is asking if you did both. Varies board to board but VERY likely you will get nothing if both aren't attached.
 
Its always funny to read these threads where the OP asks for help, then tells people he knows what the problem is and doesn't need help trouble shooting.

Just to throw this out, but are you sure the motherboard jumper control blocks, to the case headers are on? The cpu cable you yanked probably goes right over those jumper blocks too, and if it was low enough to bend a cap, it's easily low enough to yank off a jumper or two. It's definitely worth double checking that, as those jumper blocks are a lot easier to remove accidentally than you would think.

It's also possible that the PSU is just completely DOA. As the person above me asked, have you ever used that PSU before?

And the other reason I asked about the ATX connector is, at least on my Seasonic PSU, the modular end has two connections that plug into the PSU, I think its like an 18 pin and a 6 pin connection...(going from complete memory here); I was surprised when I saw it...especially since the part going to the motherboard was a 24 pin (20+4).

What in the name of god are you talking about?

Okay, this is what I did:

I un-plugged the 8-pin CPU cable, so that it wasn't taut on the CPU's end as well.

Then.. it magically started up.

I think it may have been something else, actually.

It's a modular PSU, and I plugged in a 6-pin to 8-pin cable for my GTX 280.

Apparently, that 6-pin was from another PSU, and it wouldn't start with that thing attached.

Ok, you need a 6 pin to 8 pin adapter.
PC Power and cooling sells one that should work with any power supply. You may want to check it out. I used one from them until I switched to the seasonic.
Is THIS what you're looking for?

He would still need to use a correct PCIe power cable for his modular power supply then if necessary convert from that for his GPU. It seems to me that he plugged in a modular cable from some other power supply. Or am I reading that wrong?

If its just a convertor from PCIe 6 to 8 pins that should not matter.
 
Ah you seem right. He used an improper 6 pin to begin with. Didn't catch that when trying to post at 5 am :p
