Re: 1 or 1.5 amp power supply to a fish tank

First, ensure it really is supplying a/c and not d/c current. if it is d/c ensure polarity (+ and -) is a match. then try it without the filter first. if the light seems bright enough, turn it off then turn on filter...if it seems to be running ok, then try both on for about 5 minutes. now feel if adapter is getting too should be only warm to touch. now try both on for about 30 minutes. now feel if adapter is getting too should be only slightly warmer than before. many manufacturers purposely over-rate the current draw to "be on the safe side" usually by 150 to 200% over so that your light/filter really only needs 1 amp.

Asus netbook ac power cord adapter stopped blue light on...not charging computer...what to do and need new one?

You need a replacement AC adapter, it's very cheap online.
1)Output Voltage is within +/- 5% of your old charger's output.
2) Output Current is the same or higher than that of your old charger.
3) Connector tip must fit securely into your laptop.

I have a alesis dm5 drum module. I have lost the power supply so I bought a universal power supply buti dont want to harm the system. How do i set the power supply up?

NEVER use a universal wall wart supply... it is too easy for the settings to be changed and blow the unit.

It appears that the correct power adapter supplies 9 volts AC at 1 amp (1000 ma)

Most universal adapters supply DC rather than AC.

There are sellers on eBay selling the correct adapters.

Power cord isn't working for Acer 5720

I have had good success with this notebook universal power supply. Just make sure that the clip you need is included with the item. Or you could buy an OEM (original equipment manufacture) model.

Hope this helps.

Want to upgrade power supply on Dell Dimension 4700. Bought Rocket Fish RF-550wps 550 watt powersupply to install . Unable to proceede no schematics ror placing wireing

Hi there.
Rocket Fish RF-550wps PSU is standard ATX power supply.
Dell tend to use their own power supplies which differ slightly from standard power supplies.
I suggest you take or send the Rocket Fish RF-550wps PSU back as it won't fit and order one from Dell themselves, at least then you will have a guaranteed fit.
Once you have your new power supply from Dell (or a Dell ATX power supply) it should be easy to fit in.
Post back if you need any more help.

Good luck and thanks for using FixYa!!

Asus ac adapter will not wrk green light on adapter

First check the wall socket make sure you are getting power, plug a lamp into it for instance. If there is no green light on the adapter then it is bad and you will need to order a new one from your computer manufactor.

Hi brendanram!

I am claudus_07 and i was a Dell - XPS Technical Support Specialist before so i will be glad to assist you with your concern.

As you said into your post, you tried plugging the AC Adapter to the power source without plugging the other end into the XPS laptop and the Green Light on the adapter is lit. But when you plug the jack on the laptop, the Green light is out. As for my experience on your laptop, there could be a problem with the power supply or the motherboard of your XPS laptop. Because everytime you plug the adapter to the laptop, the green light is going out so it means that the laptop or the adapter is grounded.

Here's what you need you to:

Step 1: Call Dell XPS Technical Support 1-800-624-9896
Step 2: Tell them the issue and the things that youve done.
Step 3: At the end of the troubleshooting, i know that the Technician will either replace the Power Supply, Motherboard, or the Adapter. (if you have a friend that has a Adapter same as yours, you may try to use it just to isolate the issue the Technician will choose from the Power Supply or the motherboard)
Step 4: If the Technician replaces the power supply and the issue still persists, call technical support again and ask them to replace the motherboard, no need to repeat the troubleshooting steps anymore just tell them that youre already done with it. (Dont ask for a system exchange, because i know that they will not give what you want.)

I know it will work. Be Positive!
Your good rating will be very much appreciated.

Good luck and thank you!

most notebook adapters i've seen have the light stay on as long as it's supplying power to the notebook. so your p/s maybe defective - my guess is that something's tripping it - are you sure the p/s is suitable for your particular notebook (based on voltage/current/power requirements)?
