Looking forward to the repair of those power supplys !! But i think that tool is ok. Meassuring the voltages can be tidious, but its not hard. So this tool is more for people like you who do a lot of repair. Thanks for the review !

Hi Daniel - yes I think anyway for the price of €9.33 inc postage it is a useful tool. So it is recommended by me. Actually the PSU that read 11.3V on the 12V, and the 3.3V was varying from 3.1V-3.3V I think is also faulty even though the tester did not du-du (lol) as those voltages seem out of tolerance, and 3.3V should not vary like that. The user manual says it only does the du-dus if a voltage rail is higher than normal, not lower. Still, for the price, it is a handy thing to have for sure, I'm glad I bought it.. I already started the next video on the ATX PSU that is completely dead... it is more interesting inside than I thought, especially once I found what is rattling around in there...

@@LearnElectronicsRepair Looking forward to the video ! Is 3.1V already to little for a 3.3v line ? Does that indicate faulty caps or some that are on their way out?

I have one of these testers as well. And it caused a headache. Older ATX PSU have a -5V (white wire), my version of the tester just shorts this to ground (it is marked "not connected" in newer versions of the spec). So when I connect one of those, PSU shuts down instantly as the test device is causing a short. Interesting that yours did not do that. Your first PSU hat a white wire (though that does not guarantee it is actually -5V) and also your "documentation" of the tester claims it can test -5V. About that bright light bulb: You should maybe wait a bit until the tester comes up. I have some PSU that (at least on a 60V lamp) *will* make the bulb come bright while still working fully fine. Though I see only a couple of volts arriving at the PSU, might be it will go to high current to compensate. It seems that running with the bulb only works good for smaller PSU. So I usually use the bulb only for the initial standby test (assuming it will flash and go dark) and then go to live before powering the PSU up. Risking a new fuse for the insulation transformer.

For what I know, the three leds on the left are for sata or molex, you should test them once at a time, the tester doesn't show the source it's testing. 3.3volt is good till 3.5, following the standard ATX chart.

Hi mate, From my experiments only the SATA illuminates the 3.3V LED. The other two (5V, 12V) light up with only the 24 way ATX connected (but not the 3.3V)

@@LearnElectronicsRepair I think that's because the molex connector doesn't have 3.3 volt. Moreover, the 3.3 at the bottom right corner is coming from the 24 Pin connector.

@@almostdarkslide3851 Sure of course there is 3.3V on the 24 pin ATX and not on the Molex, but for some reason this PSU analyzer only illuminates the 3.3V LED if the SATA connector is attached. I'll see if I can open it up and look at that to see how it is wired up. it would not be difficult to make it illuminate from the ATX 24 pin, but in all honesty I don't see the point of the LED only working from the SATA connector from a fault finding aspect. In fact I don't realy see the point of the LEDs at all seeing as the voltages are all clearly shown on the display screen

@@LearnElectronicsRepair leds are only for testing sata, molex and maybe floppy disk connectors. The screen shows other connectors (20+4, 4+4, 6 pins) voltages, so a led is not needed for those. I wonder if you can test sata and molex without the other connectors.

I really think its wierd when electronic testers equipment is described as hobby grade, because really with testers its just about accuracy and precision its got nothing to do with experience in an area. For example I've got a cheap multimeter and a more expensive one, say the voltage I am reading is 0.42V and I read this on the cheap multimeter, then I get the more expensive one with a higher resolution and it reads 0.42123V but I only need to know what the voltage is to 2 significant figures eg 0.42V then the cheaper multimeter is still giving me the same outcome. Just a mini rant on my part but all these tools come down to how far and accurate it can read voltages, anywy I will get back to watching the video ^^
