I've always been a fan of a UPS on a PC. Firstly Belkin, and latterly APC.
I use £20 Surge Protectors into £200 UPS to protect them also.
Having seen an electrician fry a £250k dongle on Ops, I've always been wary!
Both Belkin and APC host supplies to PC/Monitor/peripherals etc via "kettle cables"
I currently use an APC Smart-UPS 1500w - just changed the battery after 4 years after it started screaming at me!
Software lets me know via email & text that I've had a power-outage.
