I'm searching for a UPS that supports my monitor, PC, and accessories, but I'm unsure about its power consumption.
I'm searching for an UPS possibly developed by APC or CYBERPOWER. Considering the power requirements for your Corsair RMx1000w + UR59C setup, a speaker of 900-1500W might work, but I need to know if the "VA" rating is important. From what I understand, using sine-wave might be the best choice to protect sensitive electronics.
Many UPS makers offer calculators to assist in determining the right size for a UPS. Yet these tools usually favor pricier options. Often overlooked is the actual goal of a UPS. It’s designed to supply power just long enough for users to perform a smooth shutdown when the main power fails, preventing damage or corrupted files from an abrupt system or window shutdown. It’s not meant for activities like gaming, watching movies, or playing music. If you’re okay with brief shutdowns—about five minutes—then a UPS is sufficient. In cases needing longer downtime, the UPS must be appropriately sized. Perhaps it’s time to consider backup options. Regarding VA and sine wave details, I’ll leave those to others for now.
For the most part, understanding the overall needs is essential.
Mostly speakers, monitors, PCs, and any devices connected to the PC are involved. The primary purpose seems to be safeguarding against data loss or electronic damage, such as having 15-5 minutes of battery life left in case of a failure. It might also provide some protection during power surges or indirect lightning strikes, according to what I've heard.
Power surge:
Protection is provided via Joules.
Joules are cumulative: One or two big hits or perhaps a number of smaller hits.
Once the cumulative total is reached there is no more protection.

However, that said, when it comes to lightning strikes of any sort then all bets are off.
The current will go any way it can find to go: AC, audio, video, network, alarm system, camera system, coax - wires of any type.
Good chance that the spark will also simply jump through the air enroute to ground (earth). That is what lightning does anyway.
When lightning or unstable power occurs it would be difficult to confirm if 1000J is sufficient. The answer varies by location. My approach is to disconnect most devices during storms, particularly if I’m away. If I’m at home, I might leave some on but not everything. I hope severe conditions give me time to disconnect everything else. Luckily we don’t face regular power issues like surges. Lightning can deliver millions of Joules, and a direct hit usually renders all protections ineffective.

I own two small UPS units that can run for about five minutes before shutting down during outages. Both have a "Surge energy rating" of 350 J. If your situation, surroundings, and budget permit, 1000J could be adequate. Consider a UPS with an indicator to signal when surge protection fails.
I see. Yes, nothing can defeat the lightning strike, and as for the UPS, do you have any good ups in mind friend ?
There are essentially just two figures that matter to you.
The highest watts it can handle is the key metric.
VA is another related figure often highlighted in marketing, even though it’s usually a larger value.
You’re interested in the actual wattage.
This represents the maximum power the device can consistently provide.
It reflects the combined output of all connected equipment.
The next figure is somewhat more challenging to determine—it’s the battery capacity in amp hours.
This indicates how long the batteries would last under ideal conditions, assuming no energy loss during conversion from DC to AC.
Understanding this helps you gauge real-world performance.
Here, a basic grasp of simple calculations and the formula watts equals voltage times amps is useful.
For example, if your UPS uses a 9 amp hour battery at 12 volts, you’d calculate 108 watt hours.
That means it can supply 108 watts for one hour.
Batteries lose efficiency when drawn quickly, producing more heat.
While precise numbers are hard to pin down, rough estimates can be made.
Suppose your system draws 1080 watts instead of the actual 108—this would allow the batteries to last about six minutes.
Keep in mind, you’ll need to exercise caution here.
For instance, two UPS units rated at 1000 watts could be set up differently: one with a single 9Ah battery and another with two 9Ah batteries.
You can usually find more specifics by checking the replacement packs.
Generally, most UPS batteries lose capacity after three years, even without using battery power mode.
I understand, yes I've noticed those power calculators, they accurately show the remaining battery time during full power mode. People also use sine-wave or inverter types with UPS systems, but do they have any specific function?
In certain situations it would be beneficial if computers operated on 12 volts dc, allowing batteries to be placed in between the AC converter and the computer. Sine wave UPS and more important generators are now widely used. Contemporary electronics power supplies have improved significantly in converting city AC power to DC. These devices employ advanced chips that utilize sine wave signals for optimal conversion. Relying on simulated sine wave or inferior square wave UPS and generators may harm this equipment. While it is generally better to use a sine wave UPS when possible, this only becomes relevant during battery operation. Under regular conditions, the UPS merely transfers power from the city grid. You are not continuously running sensitive devices on battery power. This approach is not ideal but is often sufficient since power outages in major cities typically last only a few seconds, and you switch off the machine for longer interruptions. A generator presents a different scenario, as it is intended for extended operation. Following advice from RV communities suggests it does not immediately damage equipment, though the time required can vary depending on the device.
