Acbel API4FS06 +12v rails

[Maxxarcade]

I've been using lots of those 550w Acbel units lately, but I haven't gotten around to really looking inside of them yet.

What I'm curious about is the 3x +12v rails. One is only rated at 8 amps. Any idea which one it might be? I noticed that some connectors have a blue stripe on the 12v wire.

I Just don't want to connect a big video card or something to the wrong rail, and I'm too lazy to take it apart :-)

Maybe checking for continuity between various connectors would give an idea, but I'm not sure how the output circuits are constructed.

Hmm....I've changed my mind. I'll try to answer your question better. Thinking...

Well, I found out last week that connecting more than 6 hard drives to one of these causes it to shut down. It's possible that this one is messed up, but I haven't had a defective one yet.

Just cracked mine open. 12v3 (rated at 8A) is connected to all the molex and sata connectors (blue striped 12v wires)

12v2 connects to the 8pin EPS connector, and of coarse 12v1 is connected to the main 24pin connector.

Exactly what I needed to know, thanks!

I guess a mod is in order. I need more power for hard drives. I assume 8A would be enough to run a single core S478 P4. Maybe I could swap the connections internally.

Oddly enough, I have a Geforce GTX 460 connected to one of these, along with a hard drive and DVD burner, and it works fine. That 8A rail must be working pretty hard though.

Just thought I'd say that the 12v rail swap was a success. No problem running 9 hard drives now, and the swap was real easy. Each harness went to a single solder lug.
