Thread: Opus on the way

my system has a loose harddrive, it rests in a hole stuffed with foam. works well, is probably a fire hazard though. i never had a problem with that though, my freezups came from my pci cards, since there is no case they just flop freely and the first bump will cause the system to freeze.

for now, i just wadded up cardboard and wedged it between the two cards... the outward force is enough to keep the cards stable. i probably should think of a better solution though, im totally relying on the pci sockets for support.

I have a mo-co-so case and I'm less than impressed with the quality of the power connector. The pins and sockets seem to be so loose in the connector shells that it takes quite a bit of wiggling the connectors to get them to mate well enough to go together. I also had one pin (or is it socket? don't remember) in the case connector that was damaged when I got it and it wants to back out and make intermittent or no contact when I connect things unless I'm real careful. I was in a hurry to get something working for a trip so I just made do and its kind of stayed that way. I've been saying I'm going to toss the connector and just use a pigtail with crimp lugs to match my distribution block. I'll figure out some way to put a strain relief in place of the connector. Mine is one of the earlier units with the too-big hole for the connector so that creates issues as well.

This is exactly what my problem was, and it seems the harddrive is the first problem with loose power connectors. I would suggest to anyone out there with a mo-co case or thinking about a mo-co, replace the crappy power connectors with something more solid.

Well; the power connector I got from them (MOCOSO) never even worked in the first place. I drilled holes in the case (that I have replaced) and ran the wire directly to the Power supply. The new opus has a connector so I will be using that.

Was thinking of hot melting alot of the wires together as well to ensure they stay snug.

Installed and operating; haven't really taken it on a drive yet; I'll give some results this week.

Also mounted the HD vertically while I was in there.

Question on the jumpers; I went with the factory default of jumper 5 on JU1 which was 12.5 on and 10.5 off. I got the 10 second flash; so I removed the jumper to be on at 10.5 and off a 7.5.

I measure my voltage on at 12.2 on the ignition wire. Is there any reason I can't leave this where it is? Should I try the inbetween voltage on 11 on and 9.5 off?

Don't really feel like opening the box again.

Ok; my Opus has been in for 5 days and I haven't had any crashes. I think I am now in the Opus camp and I am a BELIEVER.

Let me just throw out a few other changes I made.

Underneath my motherboard; I put down some isolation paper between it and the mounting plate. There was a lot of space-- but some through hole parts came down and were close to the plate. I doubt they ever touched (I couldn't flex the board enough to do it)-- but better safe than sorry.

My hard disk was mounted underneath my M2ATX horizontally. Very close actually (perhaps the M2ATX generates magnetic noise???) It is now mount vertically and is spaced away from the power supply (albeit a different one).

My OPUS 120 is now in; and distanced a bit from the other boards. I also noticed that the power connector had two sets of wires for the power and ground; where the default for the M2ATX from mocoso had one. I didn't compare gauges; but it is possible that this one could carry more power. I didn't do any calculations.
