Hi.

I wil go with the 800VA model since you maybe connect another things like router, modem, etc.

Thank you for the suggestion. I’ll only connect the system unit and the monitor.

Usually you pick an UPS based on your PSU, the "general" rule says that you need to have in mind number of connections (cables), how much devices do you want to keep online in case of energy fail and how much time.

The easy way is: PSU Wattagex1.6= UPS VA

In this case: 500W*1.6=800VA

That gives you the enough power to keep the rig alive for good minutes while the energy restore or you turn off the rig.

In my case I have a 12OOW PSU but my rig does not use all that, my real use is around 600-700W and I have a 1500VA UPS. With that, I usually have around 10-15 minutes tosave my work and turn off the rig is energy is not restored
