Pete, The rating is for both in and out. BUT... and I repeat a big BUT... Just like all manufacturers the powe rsupply and ups people "stretch" their specs using measurement quirks.
First, a 200 watt power supply is a switching type so it draws considerably more peak current than 200 watts. Next the UPS is rated at 300 VA not watts. So for anything except a pure resistance (which a switching supply is not) the rating is more like 180-240 watts. Then, don't forget that the monitor draws about 60-80 watts and if you want to shutdown the machine during the outage, you will need it. I have a 300 VA UPS on one computer here and it will just barely carry it through the sags -- without the monitor. So, the AG5RS "rule of thumb" is multiply all power consumers by 1.25 and divide all power suppliers by 1.5. Doing that would say that for your 2 pc setup with 1 monitor you would consume 200+200+80 = 480 * 1.25 = about 600 watts peak. And to get that out of a UPS you would need a 900 VA UPS. The absolute minimum, IMHO, would be keeping one PC on the 300 and getting a 400-500 VA for the second PC and the Monitor. Also, you may want to know that most UPSs I have studied are rated at 10-15 minutes backup at HALF power output. With a three year old battery you might get only 1-3 minutes out of a fully loaded one. Personal experience here: Last outage my five year old 900 VA UPS carried the PC (300w), the monitor (80w), weather monitor (2w), and the network router and hubs (15w) for about 2 minutes before it shut down. Time for a new battery ($100 - sigh). Hope this helps, Ron
