I don't have that information.  And it's more trouble than it's worth to
disassemble the XPS9000 to see if that is someplace on the inside.

What kind of computer are you using?  If it is home-built, what is the PSU
make/model are you using?

Allied AL-A300ATX Rev. B, Re-capped by me (upgraded to larger caps and
replaced some swollen ones).

Oh, OK.  That's not a PFC PSU.

But in any event, hooked the Dell XPS 9000 up to the APC SUA1000 SmartUPS
this evening, and it works properly.  

Here are some interesting waveforms.  

I don't know if the BR1500 that didn't work on my Dell puts out a better
waveform than shown at this link for the BackUPS 750, but clearly the
SmartUPS both works at my site, and also puts out a good sine wave.

I've got to see if I can borrow a 'scope.

Glad you got it to work but man.. if it was me i'd have just swapped that
PSU then you'd know it would work in all situations

I re-capped it for 2 reasons, 1. financial issues (no money). And 2 the PSU
that was in the case when I got it was marked 500W on the label but the PCB
inside had a chart for fuse amperage vs. model and the biggest model was 350
watts IIRC, had NO line filtering whatsoever, had tiny heatsinks, and
weighed about as much as a feather.  The re-capped one has none of these
faults and is heavy. The "500" would probably blow smoke at loads that the
300 laughs at.
