Uninterruptible Power Supply Circuit Board

I purchased this about 2 weeks ago as a replacement for my uninterruptible power supply on my computer equipment. Less than a week ago we had another power failure that lasted about 3 hours. The EcoFlow River 2 Pro performed better than I had hoped. It transferred power seamlessly and none of my equipment even sensed it had happened. The app made it easy to manage my power usage to insure that the most critical electronics remained available.

I did not start out to want an uninterruptible power supply, but only a very capable surge protector. Once I read about the benefits of an uninterruptible power supply I was convinced I had to have one for my equipment. Initially this unit was on back order and I was sure getting one would be taking a very long time. Thankfully the day came when B&H gave me the email saying my Cyberpower EC850LCD was on it's way. I've had it protecting my computer, Time Machine and external hard drive. So far just this week the unit gave me the time to shut down safely after a short electrical blackout. I know this was a wise purchase and I am grateful to B&H for their commitment to honor my order.

I bought this for providing audio during film shoots. The design seems really tough, all metal construction. Looks like something that could be dropped on the floor a few times and still keep working. Good clean amps, but not a huge amount of gain. A few very minor critiques: uses AAA batteries ( I would have preferred AA as everything else on set uses AA), case is easy to open with ballpoint pin but can be put on backwards and then does not quite lock when closed (either make it impossible to put on backwards or it should lock when on backwards), two internal circuit board switches (mono/stereo and low/high power mode) the low/high power switch is hidden and not easily visible. It is a little awkward to have to access circuit board switches to adjust these settings. Overall very happy with the product.

Better than most RTX 4090 due to overclocking- if that's what your looking for. Power is needed from your M.Board not your power supply- And of course you need the right size case for this monster

I needed a LARGE Uninterruptible Power Source for an industrial grade Flat Bed Printer. It needed to be single phase 208V, 3,000VA output capacity. This unit by APC weighs in at 105 pounds so it's no light weight! Unpackaged and set up in a matter on minutes as the factory default settings is adequate for the intended use. The machine can be configured for use in a data rack where you can set it to for a controlled shutdown of servers and after power is restored a controlled restart, selecting 3 different power zones to restart in sequence to get your network back up and running without any user input needed. It is about the size on a large desktop computer and comes with Data Rack mounting hardware or can be used with included floor stabilizing feet.

My special 12v Power supply had a single EPS 8 pin, the Dual Xeon board required 2 x 8 pin - I tried dual Molex to 8 pin it smoked and damaged the Power Supply, LP4 to 8 pin didnt work, the only adapter that works is this EPS48ADAP brought them in from the UK thankfully they are now here in Australia

It's a power supply.

Night and day difference between this and an all circuit board pre... nice and mellow even before it hits the DAW.

Great power supply.

is there a power supply included?
