Did I fry something?

Okay, so this is quite embarrassing, but..

I was sleeving my 24-pin MB cable and I guess I must have placed the cables back in wrong, because the computer booted up for a second then shut off.

There was an extremely faint burnt smell.. and it was different than the usual one where something gets fried.

I tried to jump the PSU with the green and black cables, and it seems to work.

Does that mean my motherboard is fried?

I won't know until I get the connector right, but what are my chances?
 
Hard to say, you either have fried the board or the power supply,, you can test the power supply using a power supply tester, and if it does show to be ok, then most definitely you have toasted your motherboard. you probably shorted something out. if you can i'd rma it back to where ever you bought it from if this is the case.

Youve probably blown a cap. Check the motherboard for parts or any visible anything. Some parts can be hand replaced if you can solder. But you can't RMA it.

The cables should be like this:

Check this three times and label everything carefully! If the PSU starts up then it should be fine. You can test the pins with a meter.

You cannot RMA stuff you broke. RMA is for when the thing breaks due to fault of the manafactuer. Claiming it was is probably fruad, but it's definately not a good thing to be telling people, and puts up the cost of components. :p
 
Different manufacturers have different policies regarding rma's. Sometimes they will let you rma on this sort of thing, sometimes not.
The power supply was just hooked up incorrectly to the motherboard itself. I have knocked a cap off a videocard while installing it one time, the place i bought it from had no issue exchanging it for me once i told them what happened. He will need to contact the place he bought it from, or contact the manufacturer of the motherboard.
Then explain what has happened and they will be able to tell him what his options are.

JC man, you are not meant to be around electronic devices.

I don't think any manufacturers willingly RMA a power supply that was directly destroyed through customer modification (if that turns out to be the case here).
 
Okay, well I will test the motherboard and see if it still works and write back.

I'd much rather replace the PSU than the motherboard.

I was referring to the motherboard not the power supply.;)
 
Okay, so all you naysayers will be happy to know that I am now writing this from the computer that I allegedly fried.

Both Prime95 and FurMark run 100% fine, I've ran.. pretty much every diagnostic I know about..

And everything is just fine.

So there!
 
Are you using the same power supply? if so, i'd still keep an eye on it since you getting a burnt smell does show that some component on either the board or power supply could still have been damaged.
But good to see you got it working! :D
I worked on a friends computer, and upgraded his cpu with a faster one, and it always gave random bluescreens with the faster cpu.
But oddly enough worked fine with the slower one. Come to find out he had a few leaking caps in the power supply. I didn't find out till i had to open it up to replace a dead fan in it for him. and he used it for almost a year with the caps crapped out like that with the slower cpu, and it seemed to run fine.
(you should still hook the power supply to a power supply tester to be sure it wasn't damaged) you can get them for around 20 bucks or so.
Good luck with it.

Yes, sir, the same power supply.

No, the smoke was coming from the 24-pin on the motherboard.

A PSU tester might be a good idea. Any brand loyalty? I'll check eBay.

I do not think that a PSU tester would have solved this problem. They will not check all 24 pins to verify that the pins are wired correctly. Although a multimeter and a PSU tester could have worked. Since you can use the PSU tester to turn on the power supply and then verify the voltage on every pin yourself. Although while typing this I am thinking you would not cared much if you toasted a $14 PSU tester..

What's a multimeter?

Seriously? You don't what a multimeter is? Sorry, but I couldn't resist. A multimeter is an electronic device that gives you the ability to measure voltage, current, and resistance plus some other less common quantities.
 
I was held up at answering that question because I was kind of conflicted. As an EE I would look for a quality meter ($50 to $300) however in his case basically any working meter will do (even the $5 ones) because accuracy will not make much difference..
