Kingwin PC Computer Power Supply Tester, Digital LCD Screen, ATX/ITX/IDE/HDD/SATA/BYI (KPST-01)

using this eliminates a few steps in identifying why a computer dos not work anymore.

I bought this unit to replace my OLD tester. It works as expected, has all the connections I needed and has a display for the test results.

Buen producto funciona correctamente

I have been building computers for over 20 years and this is the first tester I have had. Wish I would have gotten one a while ago. I was having some intermittent issues with one of my computers and could not figure it out since it would power on, but some drives would not work or take a while to show up in windows. also some weird USB issues even tho the computer would boot up and run, but then sometimes crash. I put in a spare lower watt power supply and the computer seemed stable, but I really needed to confirm where the issue was because it could have been the CPU, motherboard or PSU at this point. The directions were a little awkward and seemed contradictory saying. make sure to only plug one cable in at a time, but then saying its ok to leave in the 24 pin power, cpu power and pcie cables. Everything checked out fine so I started testing my molex and sata power cables. So one sata connector was flaking out and I had to seat it right for testing. At first I thought the tester was flaky. ended up that connector was flaky, Then testing other Sata power, one showed all 3 leds lit, one only ever showed 2 lit. It was all over the place and I need to test on another psu I had to make sure it wasnt the tester and what lights were supposed to be on. Testing a new spare PSU, every single Sata connector showed 3 lights and so I determined the old PSU is what had the issue with some flaky connectors or a bad power rail in the PSU. I am not sure since it has been in service a while and I never had any issue with it. But I was able to successfully determine my issue saving me the time and cost of trying to find or purchase other parts for testing. This item is great and something I will always test from now on because it is so easy to use.

Me ha sido de muchísima utilidad a la hora de diagnosticar fuentes de PC solo se conecta y da los datos bastante precisos de la fuente ya no hay que estar puenteando cables ni usar un multímetro me gustó mucho
