New Motherboard & Power Supply Keep Rebooting Every Few Seconds

If you don’t see something that looks like that, you may want to get one. Nah, I don’t have one.. I’ll probably have to go downtown and pick one up today. I am reading this, and I hear you say that you do not want to try to start the board by shorting across the 2 power pins. However, you state that you are certain the power supply is not bad, because you have tested each of the power supply leads with a tester. Your statements lead me to believe that your assessment of your PSU may not be conclusive. A motherboard speaker, so you can listen to beep codes, is a must for troubleshooting these things. I followed this tutorial http: Checked the motherboard and CPU pins.

You can use an old personal computer power supply to run your direct current RC battery charger. This is useful when you want to charge or cycle a battery pack at home on the bench. You can usually obtain an “ATX” type supply and power cord from the computer support person where you work.

Apr 05,  · If the PC won’t come on, then the monitor won’t come on. The monitor power up is signaled from the PC video drivers. I don’t want to be tacky, but how about telling us something about the PC.

People want power in a compact form factor. They want more usable desktop and floor space. With the right components, you no longer need a big PC to handle some hardcore modern gaming. They’re fun, compact, and usually look great when completed. If you want a build that’s easy to move and can still kick ass, a mini-ITX rig might be for you. That said, mini-ITX cases are often much tighter in terms of clearances and room for error. You’ll have to spend more time planning your build, and making sure you buy components that will actually fit inside the case.

Mini-ITX cases don’t offer a lot of place to stash your wiring mess, so make sure to cut down on cabling as much as you can.

Power Supply 12 VDC 30 Watt 2.5 Amp 100 to 240 VAC

It converts a couple of 4 pin peripheral power cables into an 8 pin 12 volt cable. If you use one of these adapters then be sure to plug the 4 pin peripheral connectors into separate cables coming from the power supply. If you plug them both into the same power supply cable then you are drawing all the power of the 8 pin 12 volt connector through a single 18 gauge wire.

You can often get away with that but there’s no reason to do it. If you leave the two pieces separate then you can plug one of the 4 pin pieces into a 4 pin 12 volt connector and leave the other 4 pin piece unplugged.

Connect the power cord to the power supply, plug in your monitor and keyboard, and fire up the machine. Unless you’ve failed to connect the main leads to the motherboard, it should come right to.

Though this unit is not cool or flashy, and was not even that expensive it serves a very important purpose and is invaluable to me, just as it is to many other computer users. The UPS is able to store power and in the case of an outage it can power my computer and monitors for a number of minutes. Power sag undervoltage for up to a few seconds. Power surge overvoltage for up to a few seconds.

Brownout long term undervoltage for minutes or days. Long term overvoltage for minutes or days. Line noise superimposed on the power waveform. Frequency variation of the power waveform. Switching transient undervoltage or overvoltage for up to a few nanoseconds. Harmonic multiples of power frequency superimposed on the power waveform. Be careful not to confuse a UPS with a switch-moded power supply, which is a power supply unit PSU with an integrated battery backup.

Also, be sure to note that a UPS is in no way a generator- it only stores information, it does not produce it.

It’s also a good way to replace the distributor cap on an old car if you don’t know the firing order. The only thing you have to watch out for is that the old power supply doesn’t fall into the case while you’re working and damage the motherboard or CPU. Note that this Antec replacement power supply has an intake fan on the bottom, which puts it right next to the CPU heat sink in the standard ATX design.

As soon as the Antec power supply is in place, install the four screws to secure it.

By Vin Marshall posted Feb 2nd, at 3: There are easier ways to get a simple power supply like this one re-using a wall-wart, for instance. But if you make a power supply like this at least once in your life, you will have a much better understanding of how alternating current becomes regulated DC power. There will be many other power supplies like it, but this one will be yours.

For an LPX-style power supply (AT computers), there are two connectors: P8 and P9. Each has six pins, and you plug them into the motherboard so the black wires are together.

Mar 27, , I ran through the checklist and couldnt find anything that I did incorrectly. I ordered it from Amazon, but who knows how long they have had it. Is there any way to update it without buying a new CPU? Not sure if that gives any more information. TheDraac Mar 28, , 1: You need to connect one to the speaker header connector. Add a speaker and let us know if it’s making any sounds. One single beep indicates that it is posting properly. As for your video, you say you had one attached but don’t mention whether you get any display at all.

Ahhh the hassle of old hard drives. If you ever need to get the data off an old drive—or just want to check the drive and maybe erase it before disposal—you could always crack open your PC and mount the drive inside. There are much better solutions around these days. The trouble with an enclosure is that it takes almost as much time to mount the drive in an enclosure as it does to mount the drive in your PC.

May 28,  · Re: Using PC Power supply for power LEDs if you were to make it into a benchtop with variable voltage you could use it at low voltage to test out connections or individual leds, up to 3 .

Years ago, before I had any idea of how a computer works, my brother started to play World of Warcraft. I would always enjoy watching my brother play Jonathan Kwan February 11, Images re-encoded on April 23, You may or may not have heard of this before, you might have not even thought of this before, or if you are just wondering how it’s done, we’ll present you with the so-called “Paperclip Trick” today — a commonly known trick between computer enthusiasts and modders.

After reading the previous paragraph, you are probably still wondering, “Yeah yeah, whatever. Just tell me what the heck are you talking about!? This is too inconvenient for people who wants to use their power supply to test out certain things, and to get around this, we’ll have to fool the power supply into thinking that there is a motherboard there and the switch on your case is pressed.

If you have an extra power supply dedicated for testing components, this tutorial will also be very useful. So from now on, after this simple trick, you can now turn on your power supply with the switch at the back of it. And all you need is a paperclip and around two minutes or less of your precious time.

Shop the best selection of farm & garden supplies, tractor parts, mower blades, and more.

This one handles everything, and has capacity to spare: But what I like about it the most is how quiet it is, very unlike the surplus “server” supplies I was using, which tended to wear me down with all that acoustic racket. I selected these in particular because they were very quiet, with their cooling fans running at speeds matching how hot they get. Most of the time, the fans don’t run at all, but when they do, the slower speeds engage first, and make very little noise.

The first step to replacing a power supply or any other component in a PC is to unplug the power cable from the back of the power supply. The socket for the power cord is .

Ask Question Step 3: I decided to not cut up my PSU cables as i may need the computer it came from at some point, you will need to find the pins shown in the pic, they are on the connector that was originally on your motherboard, the cables should be green and black, any black ground connector will do the trick.

As the picture shows you need to connect your ground on your amp to the black ground cable from the connector. Once you have your two cables connected you’re ready for your next step.

Add Tip Ask Question Step 5: Power Up the Amp Here’s where whether you’re using a headunit or not comes into play, I advise everyone to do this step as a test or as a completing step. Get a small loop of wire and strip the ends, put one end in your remote on the amp and the other in the batt on your amp. This will mean that when you turn your PSU on the amp’s indicating light should turn.

If this doesn’t happen then something’s gone wrong.
