Cyberpower UPS problems: Causes PC to restart on power loss when on high load

[antony209494]

So the Cyberpower representative recommend you buy more cyberpower equipment. Are we surprised by this response?

Again we have a response from a man that designs modern power supplies for a living. I'd take his response that the power supplies can handle modified sine wave more than the response of a company rep saying "buy more of our product". Just saying.

Neither is wrong! I don't think its a matter of him pushing me to buy more of their stuff (I could buy pure sine from another brand for all he knows). In fact he showed that he cared and I can understand it even better because he happened to be from my country and I can see it from the way he talks You just approach it from a different angle.
Getting a higher quality PSU will probably work. Getting the UPS they suggest will also work! Its essentially a matter of "distortion amount" the PSU can take before the protection kicks in and that amount is less with lower or mid-range quality PSU like mine. The reason it works below 350 watts is because thats the amount of distortion it can take because of the Active PFC. Above that it trips.
Your EVGA super nova probably won't feel a thing with that UPS. But mine would need a pure sine wave one to not freak out when the power goes out.
You are approaching it from a tech enthusiast mentality which always mandates to have high quality power supplies (which ofc is correct) so you will point the finger at the PSU first which is understandable.
So stop arguing. Both sides are correct in a way. I will just choose to get the new UPS instead of replacing the PSU.

I have the greatest respect for Jon Gerow (aka JonnyGuru), but he does not design power supplies.

I'm not saying he is wrong or that he is not very knowledgeable, and I sorely miss his eponymous site no longer being up.

I'd rather replace the PSU with something of higher quality but you do you.
