Will a 230V, 330W, 600VA UPS work well for a 300W System?

My system rocks an A19 7890k (Stock Wraith cooler), A88XM-A/USB3.1 Mobo, MSI GAMINGX 4G GTX 1050Ti, a 128 gig Sata6 SSD, a 7.2k rpm SATA6 WD 1tb internal hdd, a portable 2 tb drive, and stock fan with Deepcool dukase v2 white case, and a 580W Deepcool DE580 PSU (Typical output wattage 430W).
I am going for a very reputed UPS viz. APC (Model BX600C-IN by Schneider Electric) best suited for power requirements in India.

Though its rivals are Luminous and Intex which come at a slightly lower prices than APC.
So I have a few enquiries about a UPS and its compatability with my rig's power reqmnts:
I acknowledge that a UPS compensates for under/over voltage/amperage but I wanna know how long will my system last when it is under Full and Half Loads on mains supply (Govt. household supply)  and on this UPS batteries itself (during power cuts)(Though the company's runtime chart  shows only 2 min (360 Watts) and 10 min (180 Watts) on Full and Half Loads in Watts respectively)?
extended power backup on full
The features that this particular 600VA UPS holds are pretty awesome and seem like an all-in-one complete power solution. Are they significant in practical ?

The APC page you linked has a runtime chart. It says that you will get about 4 min at 300W. That UPS has no capability to signal the PC to shutdown. That isn't optimal IMO. Ideally you want a UPS with a USB port so that the UPS can signal the PC to shutdown cleanly BEFORE the battery is exhausted.

No I have a very low budget so I have to buy the Amazon.in's Best Seller product which is literally the best I can get at that very budget showing off the cool piece of technology in this UPS.
Coming to your Auto-Shutdown Signalling S/W via USB, I don't think I''l be using it in first place and as my first prior purpose rather my only purpose is to keep my 300W-hungry rig fill the power voids so as to be running in a sound state all the time irrespective of the under/over voltaged Household Electricity or House Inverter Supply (our inverter system is a very old one "Microtek 850EB" but the battery is only 2 years old and in warranty and it compensates for the 4-5 hour power cuts sufficienetly and effectively @220-2320V, 60 Hz AC).
The inverter trips occured right after the power cut instantaneously restarts my system most of the times (90% cases) as a result of failure in power supply negotiations with the 580w PSU consequently may lead to a critical mobo and/or Components damage in future if I don't get a decent 600VA or more UPS.
So, I think that pretty much wraps it up with the APC BX600C-IN.
