I have the costco Cyber brand which looks about the same and it's a pain in the rear, anytime I play games it now goes off warning me I am using to much power, even though my PC is the only item plugged into the unit. Make sure you buy one that will support your system.

What app tells you are using too much power?

If you have a GPU that's a power piggy in my case the 3090 card, anytime the graphics in the game start to get instance the power draw is to much for the UPC and it sounds a warning sound and worse if you have the cyber software installed it shuts your system down.

Is it better to use a Li-ion battery Portable Power Station as a UPS? Seems like it's a better choice than acid batteries.

Sounds like the machine is overtaxing the UPS. That's an excellent point, though - to know the power draw from your system and get the appropriate sized UPS. This reminds me when I plug in my laser printer to the battery powered UPS, it will beep when printing b/c the power draw is way over the battery capacity.

I found it appalling that this company doesn't even list any info about if this is pure sine wave or simulated, on their own website, for a UPS.

Probably means this is simulated.

12% cashback on a popular cashback site.

Also, some Chase cards may have a 10% cashback offer. I did on one of my Chase cards.

Compared to the APC 650VA one also on sale for $49.99. For $10 more, this has some advantages:
- Battery isn't locked and can be replaced. I think for the APC one it cannot be replaced.
- This one has a screen.
- The APC one cannot be silenced based on it's reviews. This one can be.

Seems like a good deal, so got two for myself.

Depends how many disks you have in your NAS but I'd say 10 watts max per 3.5" drive. A 2 bay NAS and router should be fine. If its a home built NAS built from a desktop computer with lots of drives I'd get something bigger.

I assume you mean 12% cb if bought from Office Depot/Office Max, correct?
