Yes, there were a lot of bad PFC designs on the market for many years.
Remember (with the exclusion of PFC behavior on the front end) the front end of a power supply is (effectively) a big filter for both incoming and outgoing noise. Once the waveform hits the main filter capacitors and starts getting switched into the transformer there is no functional or practical difference to the power supply electronics whether it is a sine wave or simulated one.
I only bought highly rated PSUs, but I don't remember which one had an issue, was probably ~5 years ago. You guys think most desktops today wouldn't have a problem with a simulated sine wave UPS? Again, I don't think there's a difference in terms of longevity, just don't want a UPS that can't run my computer.
Don't spread FUD. I've been using simulated stuff for over a decade without issues and use several of them to run equipment worth over half million dollars at work.
Now, I wonder if other business Costco has them on clearance as well.
Thanks, your response is emblematic of all the hate and vitriol I've come to expect from this website. Why do you need to flame a brother for asking a question? All you needed to say was: maybe 5 years ago that was true for some power supplies, but newer power supplies have better input filters, so it no longer matters.
Oh, BTW the humble brag about the half million dollar equipment doesn't mean you're right or even smart. People do all sorts of stupid things with $1/2 million pieces of equipment. Don't believe me just Google Ferrari crashes and look at the images.

Hey, nothing to humble brag about the equipment I didn't pay for, haha. Just mentioning that there's no problem using a simulated wave UPS for expensive ass equipment. Man, you need a thicker skin if you're going to survive the internet
Most devices with motors so not do well with simulated sign wave, and microwaves. I heard a few dell power supplies might not work, but haven't encountered any pc that has problems. All home backup units like tesla powerwall are simulated sign wave.

Point taken, and i don't mean to be so touchy. I've on this site for almost 20 years, and sometimes the rancor gets to me. I see first time posters that are terrified to post because of the heat they are going to take. I honestly believe we are like brothers and sisters on this site. I'm sure if we met in a bar with anyone on this site, and certainly anyone that posted on this tread, we would have a drink together and commiserate about gpu prices, and reminisce about epic gaming builds. Maybe we should be nicer to one another.
Secondly, with regard to this UPS, I was in this exact position 6 years ago. I bought an APC simulated sine wave unit and hooked it up to my Thermaltake toughpower PSU and every time the UPS tripped my computer went off. At that time there were several posts in forums on this very website that stated modern PSU's needed pure sine wave UPS's. I'm not saying that it was necessarily right, but when I bought a cyberpower pure sine wave UPS I never had another shut down issue.
Now maybe a toughpower PSU is a cheap PSU, but not everyone is going to drop two or three c-notes on a seasonic prime titanium. I'm not sure if it's better to save $100 on your PSU and pay $30 more for you UPS. I guess everyone will need to make that decision on their own.

Yes, in my experience just about any old power supply will run on simulated sine wave, but the problem is in the change over between house power and UPS. For some reason, and maybe it is the quality of the input filtering caps as someone suggested, every time the UPS tripped my computer would go off. I could then restart and run the computer on the UPS just fine after that, but if the purpose of a UPS is to be "uninterruptable" as the name suggests, then in my experience the simulated sine wave units failed to do that with my PSU in the past. This was an issue and may still be an issue that several of the people reading this thread will experience.

Good for you. That doesn't make it a good idea. I've yet to see anything list UPS compatibility in the specs so using anything but true or pure sine wave UPS is a risk. I got lucky and learned this lesson inexpensively when a cheap automotive inverter bricked an authentic Dell laptop charger. Since then I only use non true sine wave UPS with equipment I can afford to replace.

There is no way to know how any given equipment, regardless of cost, will react to a cheap inverter. It is risky.

If you are using these cheap ups for your half million dollars equipments, you need to be fired.
