My system has a new OCZ 700w power supply.
The system is drawing about 200W with a PF~1.0
It is connected to an APC 750VA/400W UPS.
That is plugged into the same outlet as a laser printer.

When I run XP and print a file - the printer starts up and creates a brownout.
The UPS reacts, switches over, then switches back and reports it.
The computer goes on its merry way.

When I run W7 and print a file - the printer starts up and creates a brownout.
The UPS does not make any noise (as if reacting), but the computer goes to sleep, then wakes up in about 20 seconds.
And of course the printer never gets the document to print.

Where is the problem?????????

thx
