The best weg would be to measure all +5v at once with a clamp. The
planar pretty much exclusively uses +5v, so we aren't missing much by
letting -5v go unmeasured.
pig tail between the PSU and the motherboard.
Uh, the 21 pin AMP connector is unobtanium.

I was thinking sacrificial / donor parts from a dead system plainer and
power supply.
I hear that it's possible to do amazing things with 3D printers these days.
Had a few questions on 95 PSU load. At first, I thought just monitoringLouis,
the AC amps in would give us wattage. Not quite so.
There are two "levels" of power, one being the triple device power
sockets. +5v and +12v. SIMMple to deduce, read drive datasheet, done.
Just leave all taps disconnected, SIMMplify reading planar power draw. I ass-u-me the three taps are overload protected separately from the main overload. Dunno. But it makes sense that a device could be pulling more
power than it should, yet not enough to pop the breaker for overall
current.
The second "level" is the 21 pin planar power plug. We got +5v, +12v,
and -5v.
It seems possumble that we measure the wattage into an unconnected PSU,
using either a paperclip on the 8595 PSU, or the test button on the 95A
PSU. We get a "no-load" wattage, just for the PSU.
Now we can plug it into the planar, and test with one set of SIMMs, then
two, then three, then four. -MAYBE- the SIMM power draw is not lost in
the overall efficiency of the PSU.
