Power supply is the main essential source that we should added in our computer who has the computer that doesn’t labeled build up in that price list, I mean it’s just for the people who has the computer that assembled by the user or by the merchant or by someone else.
This main Idea make an outbreak idea that said “How to test the power supply for the real condition , at least to don’t deceive by the seller who service us!.
OK, so this is our mainstream of our half duplex dialog :

1. First take a piece of cable, husk the plastic surface of that cable
2. release the power supply cable that paired on the mainboard






3. Put on the tip of that cable into the green part of that power supply cable and put the another tip into the black part of that cable, and then set the power cable into the power supply and see the blower on the power supply, if it’s moving on the power supply are in good condition and if it doesn’t it was broken.
4. The another direction how to detect the condition of our power supply is put in the 3^rd with the tip of the cable, of course husk on the cable first, not the power supply cable but the another cable that we wanna use for test the power supply. and put the another tip into the 7^th, then you see the blower, if it’s moving on that blower are in right condition.
