Always recommend these to friends and family. Have gone through several of these after a bad power supply fried them, but it's cheaper to replace a tester than a motherboard. Highly recommend wearing burn/electical resistant gloves when testing, as I had one incident where the tester experienced arc flash in my hands.

I have owned and used other brands of PC power supply testers for many years and this tester outperforms my two older testers. Quality construction and nicely packed from the factory too. Easy to read screen and compared the tester voltage readings against a $800 Fluke DVM and dead on the money voltage readings that really surprised me. I like the features of this tester and well worth the money spent. I would recommend this tester to anyone who builds custom computers or repairs computers. A+

Waited forever for them to release this new version that is ready for 2025 PSU specs and was a great asset in diagnosing problems .

Thermaltake apparently tuned the PG test on this thing to be way too sensitive. This thing claims to be ATX 4.0 compliant, but it claimed that the Power Good signal on my ASUS ROG THOR PSU was bad -- only ever on the first bootup. After much handwringing, I decided to get a second opinion by buying a cheaper power supply tester (you know the one, it's those $12-$25 cheap units all over Amazon) and found the Power Good signal's response time to be *well* within ATX 4.0 spec.Also, when it fails, it just writes "F" to the screen but *does not tell you what value it was which failed*. This is bad design in my opinion - at least tell me, Dr. Power III, what number you think is bad!That said? Still giving it 4/5 stars for being fantastic in all other areas, and it has ports/features the other testers lack.

I am very satisfied with my purchase. It came in the condition as advertised by the seller. A++++ seller!!

Very handy tool to own for anyone that has a pc. It's build quality is outstanding and is very easy and quick to use. I used mine to check a new high end psu I just ordered for an upcoming build. Normally I wouldn't bother but I'm waiting for parts to come in stock before I can build it, and could be months before they do. So wanted to make sure the new unit was good and this worked great.

Works great covers all the current connections, does self diagnose, the sata connector is thin make sure you have your orientation correct before trying to seat. It’s specs out same as my flukes.87v,179,and the rest
