Inquiry Regarding Compatibility of Line Interactive UPS with Asus Zephyrus G15 GA503RM 200W Laptop

[Maniya2002]

Dear Asus Support Team,

I hope this message finds you well. I recently purchased the Asus Zephyrus G15 GA503RM 200W Laptop and have been exploring options for a suitable UPS (Uninterruptible Power Supply) to ensure stable power supply and protect my laptop from power fluctuations.

I have come across information suggesting that the use of a Line Interactive UPS may provide a simulated sine wave at its battery level. However, I am concerned about the potential impact on the laptop, as it requires a stable power source.

Could you kindly clarify whether using a Line Interactive UPS with a simulated sine wave at its battery level could potentially damage the Asus Zephyrus G15 GA503RM 200W Laptop? Alternatively, would it be advisable to invest in a Pure Sine Wave UPS for optimal compatibility and to ensure the safety of the laptop?

Your guidance on this matter is highly appreciated, and it will assist me in making an informed decision regarding the purchase of a UPS for my laptop.

Thank you for your time and assistance.

If you watch the voltage from the wall power outlet using an oscilloscope you will notice that the real world power grid do not deliver anything resembling a sine wave.  Observe your pc is quite tolerant:

Input: 100~240V AC, 50/60Hz

Conclusion: A simulated sine wave can not do any harm to your PC.

I am a little bit surprised that you do not believe the laptop battery will suffice?

Also remember your PC accepts an USB-C power source. Why not skip the AC step? 20.000mAh power banks are common and cheap, and you can quickly exchange it when it runs empty.

If you want a very long running time, you can step up a level: RAVPower Portable Power Station 252.7Wh

Compare to the 90Wh of your PC.

Now, if you are gaming 48h without sleep in a very remote area with no wall outlets, then consider a USB-C car charger and a 24v 100Ah car battery. Yes, 2400Wh. Not very expensive and this solution will keep you running.

Okay, I understand: You believe, that the 100W available from USB-C PD are far too less!?

You want to use the DC-connector? Fine, scalable solutions are available.

And as a final word: My small and neat notebook PC (not for gaming) with 16" 4K fast OLED display and an estimated power consumption of 30W get better marks with it's AMD graphics built into the CPU than a discrete RTX 2050.

A brand new notebook is not that expensive and might be a better choice than fixing your RTX 3050 laptop.
