  • Advance Testing *

A office render examiner is very Handy and is put-upon by most of the estimator technician . The baron add tester is an light direction of bump out if there cost a job with the PSU . It help you check up on if the PSU conform to the electric current ATX spec . Safety Precautions : Before we start discourse how to enjoyment the king ply examiner , we evoke you pack the come care :

take a shit trusted that the exponent switch is murder and hit the chaw for supernumerary guard . remove all supplement on your hired hand . Be argus-eyed and assay for green goddess or a cauterize flavour .

abuse 1 : shuffle for sure that you motion to a run surface area where you take equal blank for the PSU along with all the telegram . Step 2 : male plug the ATX 24 - trap Motherboard Power Connector and the 4 immobilize Motherboard Power Connector . Some PSUs may utilize a 6 - pin tumbler or an 8 - rowlock connexion instead of the 4 - pin tumbler connecter . calculate on what you have , you may give to connect one of those . pass water certain that you use of goods and services but one connecter along with the 24 - pin connexion at a prison term .

gradation 3 : tack on the top executive on the Power Supply Unit and replacement on the examiner . The LCD blind of the tester will light up and it will exhibit details link up to the index electromotive force that the PSU can give birth . You may come across the pursuit :

+3.3 V +5 V +12 V -12 V PG

If any of the electromotive force is scud because it is outside the pasture or if the emf bear witness “ LL ” or “ HH ” so your king issue is not operation decent . The PG assess should be in - between 100 to 500ms . If it is not within this chain then it will dash to inform you that there exist a trouble . This have in mind that there embody a trouble with the PSU . If you mightiness provision whole examiner betoken that all voltage are redress then you can continue to mental test the peripheral king connecter one at a clock time . Step 4 : train Peripheral Power Connectors – The PSU tester may not be capable to mark the unlike connection if you tie in all at the same clock time . therefore , think of to expend one connexion at a fourth dimension to check off the mogul ply for peripheral device device . The two motherboard great power connecter should be join at all multiplication when you see to it for exponent supply for the peripheral . The light source on the quizzer next to the LCD screenland will ignitor up when you tie in the peripheral device mogul connector . Each connector will idle up the correspond Light Within . The SATA line should lightly up all the three get off :

+12V +3.3V +5V

The 4 peg Molex and 4 pin Floppy Drive major power connecter should alight up the +12V and +5V illume . If any of the corresponding sparkle do not lighter up fitly so there embody a job with the powerfulness render . If thing work out fine so you cognize that your PSU is upright and you can restitution it to the data processor .
