The Antec TruePower Quattro TP4-850 EC power supply in HAL died, replaced by a Corsair HX850W power supply

Posted by jpluimers on 2011/10/28

After 3.5 years of operation, my Antec TruePower Quattro TP4-850 EC power supply died in machine HAL.

HAL is my storage server, it consists of this hardware:

It is organized as 2 RAID 5 arrays of 7 drives (each netting almost 11TB) each that are mirrored by a nightly job. 2 drives are hot spares. I could have done RAID 50 (now it is twice RAID 5), but this gives me the advantage of having a “yesterdays” view of the storage. Sometimes that is convenient :)

A separate (currently PATA!) disk contains the OS (currently Windows Server 2003), which will be upgraded to a SATA SSD running Windows Server 2008 later this year.

850 watts is perfectly OK, since the RAID drives don’t spin up all at once, and according to Extreme PSU Calculator Lite a 600 watt power supply should suffice.

Is it bad having the power supply to die? I think it is, especially in the way this one dies: it works for 10 minutes, then stops. The fan is still OK, so I don’t know why it dies.

Besides, my 2 Linux boxes both still run on an IBM PC 300PL Pentium 3 machines (that is, after replacing the capacitors a couple of years ago) and – though from 1999 –  they run fine (and are about to be virtualized) without any power supply problems whatsoever.

Anyway: I have replaced it with a Corsair HX850W power supply, which is modulair too, and the Molex 8981 connectors are far easier to insert and retract than the Antec ones.

Being in picky mode today, I still have two tiny things on this new power supply:

  1. Though modular, I couldn’t use the Antec power cables to the hard drives: as the connectors at the PSU side are the same, but the pin layout differs.
  2. The Corsair HDD power cables for SATA and Molex 8981 aren’t colour coded (only black stripes)


PS: Having used HDDs since the mid-80s of last century, it is very nice to see how sizes have been coming down, and capacities going up.
