The idea is to keep the system on during small outages like brownouts, ot to give you & the system time to save files & safely shut down. With a usb cable it can communicate with the system and shut it down / hibernate automatically.

The issue is actually a bit more nuanced than this. Many newer power supplies use active power factor correction (pfc) and ALSO have undersized capacitors to save some $ and meet 80 plus ratings. This means they lose power faster. The simulated sine wave ups units, which are the standard, have a very small window where it switches over from the outlet to battery power. Pure sine wave units, as a side effect of maintaining a better sine wave, have a smaller switchover time.

As an example, I have a new system built with a Seasonic PX850 platinum rated power supply. As far as I know, this unit does not have PFC, but problems can still manifest with ups units. On both my old Cyberpower 850va unit and APC 1500va unit, with a power loss the computer will reboot. On my newer simulated sine wave Cyberpower 1500va units, the system does not reboot and stays up without a hitch. So the age of the ups circuitry (both in technology and degradation) plays a factor here. Finally the secondary pc which uses a Corsair RM850 power supply will stay up fine on the old APC 1500va, showing that my Seasonic is more sensitive, but not enough to require a pure sine wave ups.

This is a great price for this unit, a price point I have paid several times over the last two years. Give it a shot and if your computer reboots when you yank the plug, you have a few options. You could consider replacing your power supply with a better one, this problem is far more common in low quality supplies that use undersized caps. The second would be to use it for your modem/router/network gear. During an outage my router & pihole stay up for 10 hours.

nothing really, some systems with active PFC power supplies won't detect the transition properly and reboot instead of staying up - that's rare nowadays, and usually occurs on older designs.

Isn't this only an issue when it's on battery power? I feel like most people will turn their systems off during outage and not have it run for extended period of time (it can't anyway, maybe for 10~20mins).

Simulated sine wave is bad for sensitive electronics which need a stable source like computers and healthcare machines. Some components may convey their incompatibility in the form of something like coil whine or monitor flickering.

I bought one of these last time this deal came up, didn't care it's stimulated wave, it's only for a home built nas. Just for reference, it idles at 120w and usually pulls 160w at load. The UPS says it has 40+ minutes of runtime at that level , just to give an idea of how much runtime at that wattage, you can extrapolate rough estimates depending on your use cases.

Was going to buy this but getting two replacement batteries for a CST135XLU at $118.

Let's see how it goes.

For all of you who want to use this with a gaming PC, careful! It's a simulated wave; it's very likely that the PC will reboot once power goes out.

Because they can. People who want a premium product or need pure sin will spend $100 more. It is just like why phones don't all come with 256GB as the lowest, even though that would only cost $20 or whatever. you should be paying a $100 premium for a 1TB phone, not a 256GB phone.

Can I use this coupon for office chair purchases?

It does. I tested it out on the Hyken chair and it work. The toatal was $140. But if was it was 10 dollar cheaper, I would buy it since it's almost a little closer to the lowest price of $125 of past SD.

It is supposed to be 2nd Thursday. Not sure if it's actually the 3rd Thursday when the 2nd Tuesday is the 8th day as a general rule or just so happened this month.

I would check if your rewards are there later Wednesday, since that's when this coupon expires.
