I have an old case with a 220w power supply with the following items being
driven from it - 486dx2 mboard with 8Mb of ram, Barracuda 2Gb drive, Wangtek
QIC 150Mb tape (QIC-02 controller, it was a cheapie), 2 fans (excluding the
power supply fan) & a 3.5 floppy drive. I have learnt something valuable. Do
not use those little power cable splitters on media devices (hard disks,
tapes), especially when you share them with fans. Gives you all sorts of weird
errors. I was bit by this once for the 2Gb drive, and again just now for the
tape drive, which could not even tolerate sharing its cable with a mostly
inactive floppy drive. I was about to send in a rather crisp bug report for
the wangtek QIC-02 driver. Fortunately shuffling around the power cables
appears to have solved the problem.
