Is it okay to buy 700va UPS for my 650w psu?

Unproductive Guy · February 19

Hi everyone, I need help with planning to buy a 700VA UPS. I'm planning to buy a 700VA UPS since I'm on a budget, and I don't think I need a 1200VA UPS if it's only properly and make sense to used for an office PC.

Here are my specs:

MONITOR HP 19 inch 1366x768
CPU　AMD Ryzen 7 5700G
GPU　NVIDIA GeForce RTX 3050 8GB
RAM　16 GB DDR4
PSU 　PSU Thermaltake Tough Power 650W TP-650AH3CCG-B 80+Gold

I know that spec wont reach 650w so im planing to buy 700va UPS,

But I don't know which one to choose. I saw two brands, APC and Prolink. Strangely, I don't understand the way it's described for both, like:

UPS PROLINK Pro700SFC 700VA PRO 360W
UPS APC BVX700LUI-MS - 700VA with AVR 360W

My question is, what is the wattage behind them? Both have 360W in their names. I believe my PC could load about 400W or less can it still handle my pc? or does that 360w happen on battery mode?. Can I use these UPSs?

The max power you can pull through them. I'd estimate the most you'd see from that system ever would be 250W (5700G+3050) if you stressed everything so that's fine.

I'd say you're looking at between 5-10 minutes of runtime, maybe more if idle.
