Hi all,

Looking of purchasing an APC UPS for my desk+networking setup.
Currently intending to purchase an APC UPS with at least 1100W to run a PSU of 850W (Corsair RMX 850).
This UPS ships with IEC 60320 C13 and C14 connections, which means that in order to plug into all my appliances (PC, monitor, audio, networking etc...) would need an adaptor plug from C13/C14 to Australian 3 pin.
I live in Australia, and where I am the mains is rated at 240V 50Hz and a current of 10A.

From what I see, the C13 and C14 connections would be compatible with the Australian 3 pin and mains supply.
Though not ideal, would it be safe to run an adaptor cord from the mains socket to the UPS, and run an adaptor cord from the output of the UPS to the cord of the appliance and then plug that cord into the appliance?
[Mains>>>Adaptor>>>UPS>>>Adaptor>>>Appliance Cord>>>Appliance]

I'm intending to purchase these cords; but not overly impressed by the need to run adaptors

Since you didn't link the specific UPS you are interested in, I can't verify the voltage and frequency support for it. That is what I would be more concerned about. The other thing that C13/C14 do is become disconnected more easily than other connectors. You need to be careful about that.

The one I was looking at is https://www.apc.com/shop/au/en/products/APC-Back-UPS-2200VA-230V-AVR-Universal-Sockets/P-BX2200MI-MS
This version is the universal socket which I later found, but would need an adaptor to plug into the mains as the input is C14.

The IEC version has connection to the mains of C19, which I believe is 16A. Since the mains has a current of 10A I assume this would be ok?

Unfortunately, these UPS systems have a bit of a high transition time, hence why they are just back-up systems. Seems slightly too high which may cause my PC to shut off. Would appreciate recommendations on a high quality unit that has minimal to zero transition time and has around 1200W of power capacity.

To size a UPS, I highly recommend performing actual wattage measurements while active. An 850W PDU is meaningless for USP sizing. You could be using 100W.

To get a zero transition time, you have to have a "double conversion" UPS. That is one that always creates the output AC from DC voltage.
They are used commercially. I recommend trying to find a used one on E-Bay. Purchase it without the batteries then buy new batteries. That is how I purchased all mine.

While this post isn't orientated towards what UPS I will need, I'm wondering if I can get away with a 960W unit. https://www.apc.com/shop/au/en/products/Back-UPS-Pro-BR-1600VA-8-Outlets-AVR-LCD-Interface/P-BR1600MI
I gather from the components I have RTX 2080, I7 9700K, 16GB RAM etc I would probably draw around 600-700W, that is, assuming at least 80% efficiency of my 850W Corsair RMX PSU I would be drawing around that 800-850W margin from the mains. Would this still be sufficient with consideration of a 90W peak power monitor plus peripherals or should I still consider a higher power draw capacity of UPS units?

You get 4 min with that UPS at 800W. It does have a USB interface to signal the PC to shutdown.
But you are still GUESSING on the actual usage of your PC. MEASURE it. Then make an informed decision -- https://www.amazon.com.au/Energenie-429-856UK-Power-Meter/dp/B003ELLGDC
