My new Opus 250W just got fried

**T_Blaze** · 12-31-2006, 10:04 PM

Today i installed my opus in my car after setting my computer inside. On first power up, the unit was fine. On the second power up, the center yellow piece by the j1 connected started to smoke. After that, the power supply power up my motherboard but will not go into post. My 12v regulated line now only puts out .02v. this sucks. Any suggestions?

btw, filled out rma number from opus already. also, with ac-dc power supply, everything boots up and works fine

Sounds like you did your power supply some damage. Did you have fuses on the power lines? Did you accidently short out the output or input wires of the PSU?
Hard to say what the yellow piece by the connector is from the pics on their site, but it looks like a capacitor. Shouldn't be too hard for them to fix it.

the power supply is fused from the battery at 100a to the distruibution amp. from the distribution block with a 50a fuse to the power supply and finally, a 15 amp in-line fuse to the motherboard.

wow thats crazy, maybe you overloaded to PSU...maybe too much voltage went through the power line. Is your ground wire grounded well?

yeah...it's grounded with a gold plated ring straight to the body. the reason why there is a big fuse is because i have a 800w amp for my subs and a 600w amp for my highs.

oops..the 15a in-line fuse is to the powersupply, not motherboard. sorry.

U sure you connected the OPUS wires correctly? The yellow is the 12V line lol i just had to ask...

Interesting, I am about ti go out and tes mine, but that sounds quite similar to what happened to mine yesterday.

yes...yellow is 12v... the one i'm using is regulated 12v line.

Right, disregard. After over 10 years of working on computers and modifiying them, I made one of the biggest NOOB mistakes.

Would you believe that the ATX plug to the mobo wasn't on all the way?! I blame the alcohol consumption of the past few weeks.

talk to chris today at opus. He said to send it in. The part that got burnt was for the regulated 12v line capacitor. I still couldn't figure why the motherboard would not go into post with the power supply but okay with the ac-dc home power supply. Any ideas?
