This is great for the price.

I was quickly able to diagnose whether my powersupply had died on me or if it was yet another system board issue.

I first tried it on a known good power supply just so I could see the results of what happens with a good power supply.

Then hooked it up to the one I felt was dead and yup only got one light to sorta flash a little bit and was able to replace just the part that had gone out and get my system back up and running.

I would Highly recommend this tool to any to help diagnose dead power supplies, at the price its at.

Now if your system turns on and has power supply issues then I would just use a multimeter however when you feel your system board has fried and you need a load to turn the power supply on, this is a great tool for doing just that.

My PS failed to power up the PC. It turned out that the 12+V line is 10.99V which is below the min spec of 11.4V. A new PS did the trick. However, when I tested the damaged PS with this device, all LEDs show green. This device will be good if the PS is dead; it can tell you that. Otherwise, it will give you a wrong assumption (some previous users made comments on this but I failed to pay attention to. This review is to re-emphasize this fact). A good old multimeter is the way to go.

This will NOT tell you if your power supply is good or bad. I test power supplies often and this will test a power supply showing good BUT when you put that power supply to a motherboard and try to power it on NOTHING. Hook another power supply to the machine and the computer works. You could have just made the wrong diagnosis if relying upon this item.

This is a pretty toy but not a tool. You may wrongly diagnose a motherboard as being bad because of this. Maybe it has something to do with a motherboard putting more of a load on a power supply than the LED's in this tester.

Mark my words- don't rely on this for real testing. You will keep bad power supplies (unless all you were going to power were LED's) and throw away good motherboards. Can we put a load on this? I really do need a good tester. Anybody??

it will not detect the minor power fluctuations that might cause your motherboard to not send the power_good signal.

That is as far as this product goes. It is fairly well constructed, has LEDs and sounds to tell if it delivers power at all but ultimatly it will only test if the powersupply is completely dead, not just dead enough not to be useful.

Bottom line: It can be useful in a quick diagnosis for the price but simply because it delivers all green doesn't mean the power supply won't have problems completely hooked up to your system.

Id probibly reccomend using a digital multimeter and a paperclip to test if you have the expertice, if not this may be a low cost option to see if you have to shell out another $80 for a new PS.

Great tester! YOu just plug everything in, and look for the lights. Takes about a minute to test if a PSU is functional (yay!) or dead (boo!). If you're a builder, or have multiple older computers around, or just like the feeling of knowing if you're components are getting power or not...well, this is $8 well spent.

I got this tester to replace my previous one, which didn't get returned when I loaned it out, because they liked my tester so much (one way to compliment it). This tester is well made, fairly rugged, and consistent when testing PC power supplies. Good quality connectors and clear LED indicators.

As other reviewers have mentioned, this unit seems to lack the sophistication to provide meaningful qualitative analysis of critical power supply parameters, such as out-of-tolerance voltages and current available under load. It's roughly analogous to sticking your fork in the toaster to see if it's plugged in: if you see sparks and your hand tingles, you've got some juice there, but that's about all that you can conclusively say about it.

In other words, if you suspect that the power supply is bad, and this device suggests that the power supply is bad, you can be reasonably certain that the power supply is bad. The converse is not necessarily true. It can and will sometimes wrongly identify a supply that will not power up a motherboard, as being 'good'. At this very moment, mine is connected to a supply that will not turn on when connected to the mobo, yet all the green lights happily wink at me as if to say 'Sucker!' In this particular case, I first tested the supply with a DVM, because I couldn't find the tester or my known-good spare PSU, and it looked good! But it shut down when connected to the mobo, so I told the computer's owner that her mobo was almost certainly a deader. Still, something nagged at me to try another power supply, which I pulled out of a 'retired' machine, and the dead computer booted right up! So I've replaced the dead PSU a that was declared 'OK' by both a DVM and this tester, and returned the functioning computer to it owner.

The Ultra tester is not completely without merit, however, and I think it's worth the modest cost. Just bear in mind that it's far more accurate and reliable reporting supplies that have failed rather than properly-functioning ones. If you need quick verification that a PSU is truly dead, this will probably do it, but positive results should be more carefully considered.
