Most likely, but that amount of load the time you'll get will be VERY short, this smaller UPS is really designed to keep up networking devices like your cable modem and wireless router, not really PC's and monitors. If the devices are energy efficient enough (I don't know if this would last more than a minute with an old CRT monitor) you should probably get some time from it, but it could be anywhere from a few seconds to a few minutes. Can't really answer without actual power consumption numbers.
