nice watch :D

I NEED SOME HELP!!

the only way to get my computer to boot is using this way

ie what is wrong with my motherboard

so what can i do no matter what i do the power button i have switched the mother bord signel has stoped working what can i do

Wait, did you record yourself with a webcam them record that video with another camera?

U not testing PSU just making sure it comes on , some times it does but u not checking +5 +3.3 +12 and other voltages .... think

THIS IS FUCKING DANGERSOUS YOU FUCKING TOOL! Dont try this at all, just buy a PSU tester, £5.

@shewasahooa No actually its not, He just did the same thing as you pushing your button on your computer. All he did was jump the green wire to any black wire. Its one of the best ways to test the power supply out of the tower. What kills a power supply is all the dust that you allow to collect in it, they do need to be cleaned out once a month.

@ shewasahooa Its not dangerous at all, if you know anything about electronics, which i can see you don't, this is the best way to test a PSU. you connect the black and green lead to turn on the PSU and you can read current and voltage on each lead. a PSU tester does not apply a load to the PSU and will give you a reading that it is good all the time, even if it is not bad. a good PSU should be able to pump out 30 amps with a load.

@shewasahooa Someone obviously doesn't know a whole lot about electricity and computers...sigh

guys, never go with a crappy power supply. Always make sure you get a good one, cause a low-end or built-in PSU can and will fry your GPU and/or mobo/cpu/etc.

I'd rather pay more at first out of my pocket than lose 600$ in hardware.

On some ps there must be load on the 5 V line, because this is sensed ba the regulator. Without load it stops working, growing the voltage to 6 V. It is important to know.

You also should test, the filters are working properly. Without the ps works, but makes noises on the wall outlet.

The noise filter in my parent's vacuum cleaner became loss and the noise let work the motor-power-"dimmer" bad.

thats just testing the fan

[fernando73820208]

thats how i test the power box

[water4fuelh20]

@firestream101 No it turns on all the voltage power at each colored wire pin, 12v, 3.3v 5v ect.

[frankdrix]

should i plugged on the power supply to the wall??

It's a little hard to see in this video, but what he is doing is taking the molex connector (the big 20 pin connector that connects to your mother board) and shorting the green wire to a black wire.

This turns your power supply on and off.

yeah... thats right!
