Your average psu uses around 5000 - 15000 uF caps on the mains side.
That lasts about 3 mains cycles. I suppose you *could* rig up a 25F
array but the caps will cost more than an average desktop machine (!)
Batteries = much cheaper.
The main reasons no vendor builds a UPS into the power supply:
1. Weight
2. Extra cost
3. Lead/acid battery = presence of sulphuric acid = bad news for
motherboards
