Two things one I need a 750Watt power supply, how do I go about finding the right one. And secondly all the connections to my hard drive and DVD burner are little black connectors instead of the white connectors need to know what they are and is there a converter connector to go to the older style?

Almost all of the newer power supplies use the black connectors - and generally come with one or two white connectors for older hardware. The best recommendation I can give you is to open the box and make sure the power supply will fit inside your computer, and the screw holes match the ones on your old power supply. Other than that it's normally a fairly easy process to change power supplies on newer computers.

How do I hardwire this unit for an in home use installation?

You would need to have a stable 12 volt DC power supply that plugs into a 120 VAC outlet. You can google these, and they come in quite a few varieties. The most expensive are the variable voltage "lab grade" ones, then the bench grade fixed voltage variety, and then the cheap consumer grade 12 volt 1 or 2 amp device designed for CB's and small 12 volt devices. But this will not work, because you are transmitting and could be putting out 40 or 50 watts with that thing. So you will need a good 10 amp to 20 amp dedicated transceiver power supply, unless you just plan on receiving in which case you only need a couple of amps and the cheapie will do. It's always better to have more amperage in a power supply. You then need to think about issues like back-up power with a gel cell 12 volt battery, which also would allow you to use the cheapie supply, because you would have plenty of current to XMIT from the battery. Schematic shows a very basic 12v - 30 amp supply. Good luck!

I have a 1990's Ampeg Reverberocket guitar amp and I had it plugged in and it just made a popping sound and i noticed the fuse had blown. So I went and got the right fuse for it and then plugged it and...

Abnormal humming sound is probably unsmoothed ac mains power finding a way to the speaker. That makes the power supply the first suspect.

Carry out a thorough visual inspection of components and circuit boards and if there is nothing obvious check the power supply by isolating it from the amplifier and if it blows the fuse again you have found the culprit and then need to narrow down the search to individual components.

Need to replace my power switching supply from my Bose ipod docker(psm36w-201) I understand they no longer make this. What are my options?

Hello. get you broken power supply re manufactured at . The parts that fail are replaced with industrial grade long-life components and if your power supply is unsafe or too far gone then they supply you a new one. Vergy green and shipping by airmail isn't too expensive.

No power on tv, no lights

there may complaint with ur tvs power supply. first of all check the voltage at the power outlet to which ur tv is connected. if it is ok check the power chord. if all these are proper then problem is inside ur tv. may its power supply fuse may burned. do not attempt to replace the fuse, because there maybe some thing is faulty at the other side, that why the fuse burned. u can find out the complaint if u have a through knowledge in electronics. if not do not attempt to do any thing. consult some qualified person.if u have knoweldge in electonics then remove the power supply board and check mosfets in the power supply board. if find some faulty components then replace it. u can switch on the power supply without connecting to the tv. be very carefull,there are high voltage points. cnonnect a 60w bulb intred in place of fuse . connect the two leads of the bulb to the two end of the fuse connector. and connect the power. if there is any problem the bulb will glose until u switch off, if not the bulb will glows once and go off after a fue second [check the standby poer supply voltage (5v)]. if so remove the bulb and insert a fuse (note the rating of fuse, use same rating). connect power supply board to ur tv. then plug it on.

Computer is dead

Most of the time it's power supply failure.

1.A lot of computer owners fail to clean the inside of their computer, plus the power supply out, on a regular basis. I find this occurrence at my shop quite a lot.
Unplugging the computer from power, observing anti-static guidelines, and using a can of compressed air for computers would have prevented this.

Power supply's have a fan for cooling, as well as heatsink's inside. When these components collect dirt, dust, hair, and other foreign objects, the cooling capacity drops tremendously.
Heat = Wasted Energy
The power supply struggles to keep up with the demand of power needed, and eventually components inside it fail.

2.Most power supply's installed in a pre-built computer, are of a low grade of quality. (MOST. Generally pre-built computers manufactured in the last two years, have upgraded the quality of their power supply's, but not all of them)

Saves the computer manufacturer money. These power supply's have low quality components. Gauge of wire used is smaller than it should be, Electrolytic Capacitors are of an inferior grade, transformers are cheaply made, and the rectifier bridge is cheaply constructed, are a few examples.

3.Computers that are built by the owner, and are not pre-built, may have a cheap, or underrated power supply installed. You really have to check out reviews for power supply's on the internet, to see what quality it has. However there are some websites, that 'pump up' the review to stay in good standing with the power supply manufacturer. Generally, if the power supply price is cheap, so is the quality.

There are two other things to look at.
It may be the Power On switch that is behind the Power On button. These can go out.

It could be the motherboard. Most of the time it is Electrolytic Capacitors that are the 'weakest link'. Specifically the one's that surround the processor. These 'Caps' are Voltage Regulators for the processor. If even One is bad, the processor will not work.
No processor, No computer.

How to know if it's the power supply? Use a known, good, and compatible power supply for a test. [Compatible being that the power supply has the required power cables for the motherboard, and enough Wattage]

How to know if there are bad Electrolytic Capacitors on the motherboard?
This website has information, plus photos of bad capacitors,

Hp pavilion 764c wire diagrams

Take a picture of the inside of your computer and put it up on the website with the wire connectors that need to be connected. The connecting wires should be in four groups. 1. The power supply connectors. These connectors will supply power to to all the power using components not supplied power by the motherboard itself. 2 The connections to the other components in your system like the dvd/cd player and the harddrive and floppy drive.3. The motherboard connections for the case. The power switch connector andreset switchconnector. The power led and theharddrive activity light.The USB connector and the audio connector.The fan connections like the cpu fan and other fan only connectors found on the motherboard.The external fans ( Fans that need to be connected to the power supply).Most of these connections are labeled on the motherboard. The case connectors also should be labeled for the correct connection. The best way to find the answers to this hook-up, may be to call HP pavilion with your computer make and model number,motherboard model number including revisions number. Computer made by big manufacturers tend to have may revisions and the only way to make sure your are getting a correct hook-up to the motherboard is call them for assistance.Especially if the motherboard and case labels are not present or so small that they cannot be read.Hope this helps you with your problem.

Wireless keeps going down

Your problem could very well be your wall plug power supply, they are cheaply made with low grade components which do not last. Over time they start failing and the power supply to the router becomes unstable, the router than starts doing funny stuff such as been intermittent.
Find a replacement power supply, preferably with a littlebit higher current rating and your problem goes away.

Hope it helps you.

Acer RC500 power supply problem

I experienced this very thing today. Disconnect everything and then reconnect. Make sure that every connection is accurate and also make sure that the spacers, or gold screws in between the case's body and the motherboard, are in place. If the fans are starting for a split second and then the computer shuts off then this should fix your problem. Otherwise if you're using all of the same components I can't think of any reason this should happen.
