I looking to buy an APC Easy UPS BV 1000VA in order to have my PS5 attached to because lately we are getting a-lot of power surges so I wanted something to give me time to close the console before anything happens. But the power outlet is not near my tv so I have been using a power strip to connect my PS5, tv and the controller charger stand. My question is does the ups still work if my PS5 is attached to it using a power strip,
Yes, anything plugged in “downstream” from your UPS, will be protected.
However, (to cover my ass) you will need to check with your electrical AHJ (Authority Having Jurisdiction) to see if it is permissible to plug in that power strip into your UPS.
Good Luck!
