Question regarding 500W UPS on a PC with 620W SMPS

[WILDLEGHORN]

So right now I have a 500W UPS or Uninterrupted Power Supply from 'American Power Conservation' to provide backup power for a few mins on my old PC which has a 500W SMPS as well.

Shortly I'll be moving onto a new gaming PC with 620W SMPS in a few days & I just wanna know if having that same 500W UPS on a PC with 620W SMPS will cause me any problems or not while heavy gaming? Will it get overloaded or something while running my system on full load for few hours?? And will it give me enough time (say 1-2 mins) to shut down my PC when power goes out?

I just need my UPS to shut down my system properly in case of load-shedding & power outages, which are rather quite frequent during summer times. I need only maybe a minute or two to shut down the game I'm playing & turn my system off from windows! That's all I need a UPS for & right now I'm very short on money right now to buy a brand new UPS unless it's absolutely needed & the current 500W one won't suffice!!!

Unless your power consumption goes above 500W(which I highly doubt),you should be fine.

You need a new UPS, because while heavy gaming the consumtion of power increases and if it crosses 500W and at the same time if light goes off, then your PSU wont be enough to handle that much power and then there might be problems with your PSU and the pc will improperly ie. directly turn off.

You have to get a new one.

Yea i see what you're saying & you're probably right
This means spending more money

At max CPU tdp with OC & 100% peak load with 15% capacitor aging:
Minimum PSU Wattage: 500 W
Recommended : 550 W

One very important thing:
I had to choose GTX 680 as my GPU since GTX 670 was not available there idk why

They are not quite useful!!
