If I hold a four foot florescent light out pointing it at the antenna and key the mike it will light up the bulb. Thanks for providing such an easy-to-follow Instructable -- this is something I've wanted to make for a while and was finally able to take the plunge. Firstly and more importantly before you start to convert ATX PSU, make sure that the PSU is unplugged from the mains supply and discharged by letting it sit unconnected for several Then you can run the power from your power supply into the buck converter and it will output 5V.

However the easiest way is just to buy a 5V, 1A power weblink

Begin with the 3.3V wire (orange) on the far left, then the 5V wire (red), the +12V wire (yellow), and the -12V wire (blue).Step #10: If Necessary, Add a 10W Resistor Number 2, for the PSU to correctly regulate the +5V output voltage it needs to have some sort of load attached, at least 5W to trick the PSU into thinking its Yonian If you're ever going to use molded dual banana plugs you should space your jack pairs 3/4 inch (19mm) apart.

Atx Power Supply Pinout

Without this load, the output voltages may vary significantly from the specified voltages or the power supply might shut itself off. Connect the Green Wire to the Power Switch7. Once it gets this confusing, the next step is to unplug the supply from the wall, and let it sit overnight.. I also used the same colored wires to help keep track of them.

Not bad for something that would otherwise get thrown away. For the same example, only 37% of the units (fewer than a half) are expected to last 100,000hours without failing.[a] The formula for calculating predicted reliability, R(t), is R(t) = e There are other converters like switch mode converters (a buck converter) but these are usually more complex. Power Supply Function Retrieved 2014-06-29. ^ "Redundancy: N+1, N+2 vs. 2N vs. 2N+1".

Using higher quality electrical components at less than their maximum ratings or providing better cooling can contribute to a higher MTBF rating because lower stress and lower operating temperatures decrease component Psu Computer The −12V rail was used primarily to provide the negative supply voltage to the RS-232 serial ports. The connector has 20 or 24 pins. In this case, 90W/24V = 3.75A, so you should be good to go with the output set at 19V with this amount of current.

You will also be receiving the weekly Make: Newsletter to keep you inspired with new projects and more product reviews. Power Supply Price The only colors we care about are Black, Red, Orange, Yellow ... 4 Step 4: Grouping WiresGroup the 4 wire colors together and cut them to length to where you marked Worth a try if you're struggling to get your supply up and running.

Correct, a switch-mode power supply will need a load to operate properly.

I use a 10ohm, 25watt power resistor from Before we begin, here is some background information on computer power supplies.

Psu Computer

Retrieved 2009-09-24. I can ask for anything as long as it isn't more than the 10 liter per minute. Atx Power Supply Pinout Auxiliary power connectors: There are several types of auxiliary connectors designed to provide additional power if it is needed. Computer Power Supply Voltages They are perfect for general electronics.This is my first Instructable for what I think is a brilliant idea, I'm only 14 and i can build itWARNING: This will void warranty's and

Sponsored by SCAN Related Reading 1 be quiet! http://olivettipc.com/power-supply/reusing-old-power-supply.html If you want to maximize the amount of current you get from each supply output (3.3V, 5V, 12V) then you can wire as many of the corresponding wires together as each Less waste equals less heat produced, and of course lower electricity bills. Why use a computer (ATX) power supply? Types Of Power Supply

And look retro-cool. :) Raptor217 An LED cannot be used as a minimum load requirement. I did one mistake I didn't used PCB because I considered it to be fairly simple project, but now fixing will be real pain. The lemon-market in PC power supplies has now officially become bad enough that no-name generic "500W" PSUs may actually barely even be able to deliver 250watts. check over here This connector is used to supply power directly to a PC's processor.

This is controlled by the green "power on" wire. Power Supply Connectors I'm definitely going to do this. Am I missing something else?

Some power supply form factor specifications provide guidelines showing typical power distributions for various output rating totals.

In that sense, unlike with voltage, the current rating of a power supply must be at least what the device wants but there is no harm in it being higher. If you check the output specifications for the power supply, you will normally see listed all the different voltages that the power supply provides, and the amount of current it can Climate Savers Computing Initiative promotes energy saving and reduction of greenhouse gas emissions by encouraging development and use of more efficient power supplies. 80 PLUS certifies power supplies that meet certain Power Supply Circuit Diagram Thanks.

The device will only draw the needed 3.3A which is well-within the capabilities of the PSU.

It's not straightforward to directly use an [email protected] power supply with a device that requires [email protected] You will also be receiving the weekly Make: Newsletter to keep you inspired with new projects and more product reviews. AnandTech. this content Sometimes, if you're lucky, they have the wires labeled on the PBC of the supply..
