how large a power supply is needed?

You can use any sized 12v supply but to reach full functionality you should use 320 watt (4 x 80w = 320 watt power supply) or larger. This will give you full 4 port x 80 watt charging.

You need an adapter to plug into the house plug or connect to a car battery

The total power required for all channels operating and max is 320 watts - about 25 amps at 13volts. I'm using a 12-15VDC switcher power supply with 30 capacity and have never run into an issue. Respectfully, David

If you were going to use all four ports at their maximum rated capacity you'd need a 350 watt supply minimum. How you arrive at that is up to you. It can be powered by 11-18v supply, so if you were going to use a 12v supply, you'd need around a 26 amp supply, but if your power supply is 18v, it would only need to be 18 amp. I'm powering mine from a bench supply I use for electronics work that is based off an ATX power supply with a 30A 12v rail.

I ordered the nitrothunder 40 amp. http://www.nitrorcthunder.com/Power%20supply.htm

I would go by the specs of the power supply recommended by Hitec (ePowerBox 30-amp Power Supply). I got their power supply and it seems to work fine).

It can charge up to 4 batteries at a rate of 6 amps each. A 20 amp could do the job if you are not charging 4 packs at full capacity at once. A 30 amp power supply is a safe place if you are going to charge multiple batteries at once. Here's a good 20 AMP supply. Racer's Edge 20 Amp, 13.5V DC Dual Output RC Power Supply with USB

I wouldn't buy it. I did, and after draining the car battery once I just ordered the AC and have been happy ever since.

Depends on what else you're running but, I would recommend at a minimum a 550 watt unit; 650 would probably be better; 850 if you want to future proof your computer. This all assumes you're using a desktop and not a laptop computer.

I would get at least 700 watt supply considering the other components in your rig to be safe.

If you use a branded or certified power supply (i.e. thermaltake, antec, coolermaster, etc), 420W should be enough (at least 700W for a generic power supply). There are several power calculators in the web so you can be more specific (i.e. aditional fans, lights, drives). I made a calculation with a mid range processor (core i5) and 2 x GT630 (crossfire), and still did not need more than 420W. I hope that helps.

If you have on a built in (on the motherboard) video card- 350 watt is fine. If you have a external gamer video card, then a bigger power supply you will need. These Antec power supplies are a VERY good choice.

Paul Buff "Vagabond" regular or mini works well.. U don't need a large power supply.

60Watts is the minimum that you should use if that's what your computer says. Using a 90W power supply is actually preferable as it will last longer and run cooler.

I would get a big higher wattage on your place. There is a good tool from ASUS to calculate the approximate PSU power you will require for your system: http://support.asus.com/powersupply.aspx

It depends what you plan to do. I have a 1500w power supply and fold.You just want to look at all the the hardware you use and see what you actually need when its pushed to the limit, especially if you plan to overclock and/or use 24/7.http://www.youtube.com/watch?v=QQdgubDirTU

Depends upon what is installed in your computer. CPU, hard drive, video card,RAM, motherboard including optical drive all need power. I would say 350 watts and above would be a safe bet.

That is a popular question, you can check on Toms Hardware for other discussions. AMD recommends 400w, I also used an Antec 550w for mine but others have reported that they got by with 300w but it depends on the efficiency of the power supply.

Its a 500 watt power supply you could probably google it. It shouldnt have much effect espically if you are already running a desktop.

From memory a 400 Watt PSU is needed. I went 500 Watts just so I could have a little extra.

I cannot find requirements on the power supply, I personally have a 500W unit. I have no reason to think a 300W would not work. You should be good.

300 watt is the minimum requirement. It will run on this power supply but it would be better to have a bigger power supply

Here is where I start when I want to calculate the amount needed: http://www.extreme.outervision.com/psucalculatorlite.jsp (Although it looks like it doesn't have your CPU yet.)You'll probably be fine with an 800w power supply, although you'll need to make sure the rail(s) can handle the graphics card. Also, will you be (in the future) adding another graphics card? If so, I'd say get the 1300w one and then you won't ever have to worry about it.

400 would be pushing it. I have a 600w and it does fine. I would say the minimum would be 500w but it really depends on your total power consumption system wide.
