Problems with Zippy 3x redundant PSU

[Maxxarcade]

I have a big 4U file server that I bought used. It has a triple redundant Zippy PSU, with 3 of the MIN-6250P modules in it.

The first time I turned it on, one of them blew. I was able to run it with two of them during testing, and didn't have any more trouble for a few days.

Today I powered it up and another one blew. I only had one hard drive installed, so I know it was not overloaded.

Do these have a history of blowing when they get old? The fans are all good, as well as the caps.

Luckily the motherboard seems to be fine after all this.

Just removed it and found that it is a model MR3-6460P, 2+1 redundant 460W. This PSU costs about $400 new... Maybe it would be worth trying to fix the bad modules.

I would just put my 700W Zippy single PSU in it's place, but there are not enough connectors, and the brackets are different. I need about 20 hard drive power connectors since this is a 16 bay hot swap case.

Yep, I've got that bookmarked in case I can't get this one going next week.

Despite the problems, I can't complain. A 16 bay hot swap IDE case, with a dual Xeon 2.4Ghz server motherboard for $99 is a bargain I'd say, bad PSU or not. But I was pretty bummed, because I just got the rails installed in my rack and was ready to put the rest of the hard drives in. The test run with 8 drives went well, before the PSU blew out.

Better that it went now than at a critical time.

Ironically, my current server has gone down twice because of a bad connection somewhere, that caused an instant reboot whenever the rack was bumped. Luckily no data seems to have been lost.

Just like my ATX case that been in the same spot for around a year, but I somehow still seem to trip over it causing a reboot. Only one WD360 drive and no data loss here either. Maybe it's the NTFS?
