possible power issues?

[Fullmetal Chocobo]

I had to deal with this a lot, but I haven't had problems in a long time. Just a few minutes ago, I was defragging my documents partition, which resides on my RAID 5 array, and moving files from \downloads to where they actually begin on my storage partition (which is also resides on the RAID 5 array).

I then get an error saying disk 3 has gone offline, and the array has gone critical. Still functioning, but if one more drive failed, everything would be gone.

I went and immediately turned the computer off, checked the normal stuff, cables and everythign else. Turned it back on, drive was there and fine, and proceeded to get the array to start rebuilding (yay 12 hour wait).

Here is my list of equipment and what PSU they are powered off of...
PSU 1 (Enermax 660w)
-SuperMicro X5DAE mobo
-dual Xeon 2.66 GHz
-4x512mb PC2100 DIMMs
-2xPanaflo M1A fans (on the procs)
-2xCoolerMaster Cool Drive 3
-2xWestern Digital 120gb PATA hd
-Audigy 2 Gamer
-BroadCom 4852 RAID controller
-BFG 6800 GT OC (through AGP only)

PSU2 (Enermax 460w)
-BFG 6800 GT OC (aux power only)
-5xHitachi 250gb SATA hd
-Plextor 48X/24X/48X CD-RW
-8xcase fans (80mm, 2600 rpm, 33db, 48.5 cfm)
-2xcase fans (120mm AC Ryan, 2.8W, 2k rpm, 28.95 db, 77.70 cfm)
-had a dual 12" cold cathode which was just removed

I know this is a shot in the dark, but any ideas?

CLIFFS:
1. Look at above list.
2. HD dropped out during heavy-ish hd usage
3. Possibly overtaxing 460w PSU?

Why don't you switch your power supplies lol...

460w with 5 hard drives, 8 fans. 2 120mm fans, with everything... omfg.
yeah, try switching to the 660w lol... Get an adapter and try.

I vote heat issue.

Temps: CPU1: 114F; CPU2: 118F; system: 114F. The sides of the case are currently off, as I'm working on modding the side panels and all. All of the hard drives are on these Zalman ZM-2HC2 hd coolers, and the fans are sucking air which has to go over the hds. But that is something that I will keep in mind and investigate.

As far as switching them, that isn't possible, because I have the 24p connector cut off of the 460w power supply. It is modded so that it is turned on by a switch in the front. If it seems that I have to replace that PSU, then I will just buy another one with the largest +12 capacity I can find, because I'm looking at adding 3xdual 12" cold cathodes, 2xsingle 12" cold cathodes, and 1 15" cold cathodes, plus 2x120mm fans and another 80 mm fan, all on that PSU. So I"ll have to see how that works out. Guess I'll start researching that now.

I dont think its PSU.....its more like the heat....a 460W PSU just cant drop the HDD...almost impossible unless the rails are very very unstable

That is BS. Size does not matter, because even the biggest of PSU's can have problems. I have this problem on my PC but it is not due to faulty PSU electronics but becuase one of the wires inside of the molex is loose and will cause the Drive to stop if the case is bumped.

Well, I've had this problem before, back when I only had the 660w PSU. It drove me nuts, because the hard drives would drop out all the time. I got the second PSU, and haven't had problems for a long time. And the fact that it was under heavy hard drive usage has me wondering if it's time to sell the secondary and get a new one.

Anyone of the morning crew have any ideas?

Nothing besides a recomendation against dual 12v rails in your new psu

 

[Fullmetal Chocobo]

Why no dual +12V rails?
