      Hello Panther911, It is best practice to look up the power requirements of the equipment before making a purchase. The SE450G1 is a 260 watt unit. A PS4 and a TV is likely exceeding the capabilities of the unit. If you need assistance with product selection, please reach out to our sales team at 877-297-6937 option 2, and we'd be happy to help.

    I love this thing. Instead of plugging a single device into one socket you can plug 8 devices into 8 sockets! Also does great in power outages and fluctuations. It's done a great job for me.

    Excellent battery backup!

    I live in a place where power issues are common, and this product has exceeded my expectations. I am using it to keep a 24 inch curved monitor, and a brand new gaming PC, as well as a brand new WiFi expansion system alive whenever there is a power problem, and it's kept everything working right and without problems every time there is a blackout, and whenever there is some power surge, my devices barely ever feel the impact; if they feel it at all. The design is quite common, but its compact looks would sit well anywhere it is set, and it's long cable is just perfect for it to reach easily where you need it. I would recommend this to anyone!

    This unit seems to be performing adequately. It is specifically designed to keep your tower running during an outage in order to shut down the computer properly. Luckily, I've not had to use it under those conditions.

    last night.i was doing some office work on my pc. when I had to many things on at the same time. every thing went off. and I heard a beeping sound out of my cyber power. I got the lights back on 5 mins later. when they came on. everything I had pluged in to my cyber power. worked out so well. so I went back to best buy to get more of them. would not change a thing. some times if you want the best. you have to pay. and I payed 1500 $ for my pc. it is worth it. I recommend it to anyone. and it has a 3 years warranty. and for the battery.
