i don't think 450w is NOT enough to run a ps4

Why do you argue when you always have the evidence in front of you for every question you pose on this forum? Your ups doesn't keep the ps4 on when you unplug it. Your bigger one does. Obviously the 450w doesn't have enough power to sustain your ps4 in the case of a power outage. You told us this yourself. How is this hard to comprehend when you told us this yourself?

max power of 250w is the specifics. you have other things plugged in with it then it'll probably turn off.

google is powerful.

also. if it doesn't work then it doesn't work. it doesn't matter if numbers say it should. the fact is it doesn't run, why bother asking?

a pc with equal specs prob takes about 700w power supply so the 450 not being enough could be the issue
specially if your trying to get ps4+ tv n shit

You sure its not plugged into the "surge protection side"? If it is a consumer grade UPS chances are half of the ports are surge protection and the other half have the battery back up
