Question Should I change/upgrade my current UPS?

[AristosT]

Hello everyone,

currently I have the CP1500EPFCLCD CyberPower UPS, that has 900W capacity. I have it since October of 2020 and it has been amazing, never had a problem with it in any shape or form, I have been very pleased with it. My question now is, almost 5 years later, should I change/upgrade it? My current PC setup is:

GPU: MSI GeForce RTX 5090 Gaming Trio OC
CPU: AMD 9950X3D
CPU Cooler: Arctic Liquid Freezer III 420 A-RGB White
Motherboard: MSI MAG X870 TOMAHAWK WIFI ATX
RAM: G.Skill Ripjaws M5 Neo RGB 64GB DDR5 (F5-6000J2836G32GX2-RM5NRK)
PSU: PSU BE QUIET DARK POWER PRO 13 1600W
Storage(all are m.2): Corsair MP700 PRO SE SSD 4TB M.2
ADATA SX8200 2TB
Kingston KC3000 4TB
Seagate FireCuda 530R SSD 4TB
PC Case: Antec Flux Pro Gaming Full Tower (4x140mm fans and 2x120mm fans)
Headphones: SteelSeries Arctis Nova Pro
Keyboard: Apex Pro TKL Gen 3
Mouse: Logitech G502 X Plus RGB Wireless
Monitor: Gigabyte Aorus FO27Q3 OLED HDR 360Hz 27" QHD

I have plugged in my PC, my router and my Monitor on my UPS, nothing more. When I measure my overall power draw with HWinfo64, I draw around 800-980W on heavy games like Cyberpunk 2077 (all settings maxed out). In order for me to not draw over 900W on games like that I have slightly undervolted my GPU and mostly apply FPS limits of 90-120 on these heavy games. My UPS has never stopped working or displayed a warning or error even after I saw more than 900W on HWinfo64. My questions are:
1) Should I upgrade to another UPS that has more capacity? Or is it okay since I undervolted and apply fps limits for power draw, and just check to not go over 900W?
2) Even if my current UPS watt capacity etc is okay, should I upgrade just because of battery degradation? In October of 2025, my current UPS will be exactly 5 years old, and I have heard most UPS batteries need to be changed or replaced even if they are not faulty, every 3-5 years, is that correct?
3) If I need to buy a new UPS, I would like some recommendations since I am not very knowledgable in the UPS space. The ones that have stood out to me are CP1600EPFCLCD and VP1600ELCD, which from what I can tell are pretty much the same as my current one just newer and can support up to 1000W and 960W respectively which is not much higher than 900W to be honest. Also, I have found many UPS that are over 1000W but they either have a fan constantly running (which is a huge no for me, I need it to be quiet since I have my ups in a small room and not a server room) or they either only have IEC ports and not Schuko (I only need Schuko, minimum of 3 and max of 6).

Thank you in advance for taking time to read and reply to my questions!
If you need more information about my setup or anything please let me know.

1| If your UPS is meant for battery backup in the event your power grid goes down and you need to save and shutdown without a hitch, and it's been doing so till today without an issue, then no - no need to change.

2| Does the UPS fail at it's task? If yes, then you replace the batteries. If no, keep an eye on it.

3| IMHO, you don't exactly need a 1.6KW PSU for your build, you could've gone away with a 1.2KW unit.

My 2 cents.

Thank you for your reply!

1)Yes its meant to keep power in order for me to save and close everything normally and it has been doing its job at that, my only problem is if im using over 900W of power (for example playing a heavy game like cyberpunk2077) and the power goes down at the moment my setup is drawing >900 watts, would that mean the UPS wont work at all and shut off instantly? it hasnt happened yet and the odds of that are super low (for me to lose power exactly when im drawing >900 watts)

2)No it hasnt failed yet, although it hasnt gone through alot of power outages, id say around 15-20 in 4-5 years. But still, i havent observed any problem with it yet.

3) I know its overkill, but everything else was overkill so i might as well get one of the best PSU's, thats how i thought about it. And I might do some upgrades in the feature so it might come in handy (more RAM, more fans, RGB strips etc)
