thanks for the quick reply

Since you're fusing something, look at buying a circuit breaker instead. They cost a little more, but they're resettable and some have a lower voltage drop than a fuse.

Hey,

When I finally get around to putting in my carputer, I'm going to fuse every power line I run up to the dash, that way if one of them happens to short to ground somehow, only that device will stop working and it will be simple to troubleshoot because one fuse is blown and I know exactly what to test. I dont know if the Opus has fuses on its individual supply lines, because they assume the wires will be safely running inside a computer case with low chances of shorts, but running wires under the carpet and seats is a totally different story. Also, if you do happen to blow a fuse on the Opus board itself, arent they the solder-in microfuses that are hard to find and a pain to change, especially when you blow a few trying to fix the problem. It all depends on how cautious you want to be and how hard it is to rip apart your dash and run wires. Hope this helps.

Even the cheapest PSUs usually have overdraw protection and will shut down in case of short without damage. Of course it doesn't hurt to fuse its output, but if you're hoping they'll trip instead of the PSU, it's pretty much a quick draw contest at that point - you'll want the fastest response fuses that you can get.

Like hijinks said, I'd just fuse at the battery.
