What size power station runs a desktop computer?
A typical desktop + monitor; gaming rigs draw far more — size for yours.

What size you need for 4.0 h
Running watts (everything on at once) = 200 W
Surge watts (worst single startup + the rest running) = 400 W
Average draw (cyclic loads counted by their duty cycle) = 200 W
Watt-hours = 200 W × 4.0 h ÷ 90% usable reserve = 889 Wh

Common questions
What size power station do I need to run a desktop computer?
A desktop computer draws about 200 W running, with a startup surge near 400 W. So you want a unit with at least 200 W continuous output and 400 W+ surge. For 4.0 h of runtime that's roughly 889 Wh of capacity — the Goal Zero Yeti 1000 Core is the smallest unit that clears all of it.
How many watts does a desktop computer use?
About 200 W while running, spiking to roughly 400 W on startup.
