Are the batteries drained when using the power supply? When using the PS should I remove the batteries?

I would ASSUME the batteries are not drained while plugged in to the power supply (which does not answer your question - I realize that). However, you should ALWAYS take the batteries out of a unit when the unit is plugged for any period of time (or not in use for any period of time) because batteries will leak and ruin the device. I have had several sets of different brands of batteries leak in the last few years.

I have not needed batteries but power the WH FM Transmitter 3.0 off a USB port (adapter came with the transmitter) on my Imac. Succinctly put, you do not need batteries if you use an alternative power supply.

Require a power supply: No; Batteries: My book says "to provide back up power". Others have mentioned that the batteries don't last to long

I don't know either. I don't use it on battery. And I keep it plugged into my PC's UPS.

I am actually using a 300w PSU and everything works just fine for the past week (i7-4770, 8G ram, two HDs). But don't try to take my word and keep a 300w psu for long bc it's supposed to be dangerous to your equipment. I've ordered a 500W PSU and will replace as soon as it arrives.

i have had about 8 1kw or larger ups and the only time they "buzz" is when they are charging a depleted battery. i would unplug it and leave the load connected and see how long the battery last. if it dies in short period of time then probably there is a problem and the unit is charging all the time. it should go into charging mode very seldom because the load is normally not off the batteries and on the power line. the battery should stay charged and not need charging.

not need to be plugged in straight to the power supply. I have a 300W PSU and work fine

yes it is,but unless you are going to have an external power supply do yourself a favor and do not buy it. Batteries do not last .

I found the link to the manual: http://www.powerstationusa.com/manuals/PSX3.pdf Right on top of the cover pager (1st) it says that "... THIS UNIT CAN BE LEFT PLUGGED IN AT ALL TIMES TO ENSURE A FULL CHARGE WHEN NEEDED."

My power supply flaked out within 3 months of purchase. I was prepared though. I had purchased an extra one from ebay for a little less than $20.

I had mine for over a year now and we use it all the time....no problems. I would troubleshoot the power connections before removing it.

Yes it has been fixed at least in the one I bought. No whine or any noise for that matter, sometimes I wonder if the fan even works. This is truly the best power supply I have ever owned and it is extremely efficient. I noticed a 32Watt drop in power usage after in installing it. Migrated from a PC-Power & Cooling PS measured by Kill-A-Watt.

I used this in a UPS (uninterruptible power supply) for a computer. They battery is rarely activated, and the last one I got lasted over 5 years. I would check the VA and make sure its compatible with the equipment you are planning to use it with.

no power supply. BUT the batteries you put in there last for such a long time, I am, actually, very shocked and pleased!

The power supply went bad on mine within minutes of opening the box. I replaced it and it has been working fine since

I purchased one and had to return it. The power supply was defective out of the box and it wouldn't always turn on using batteries.When it did turn on it would not zero. My advice is to send it back.

I have never owned this power supply. So, I can not really tell you if it is or not. I have owned several computers over the years. I have heard any of my power supplies while they were running. SO! What do you think the answer should be here?? You have never had a power supply? So, you did not know they ran quiet. Come on buddy. Are you older then six?

My power supply is similar and I have been using it for about a year now with no issues. I also use dual monitors. I'd at least try it out.
