work great, nothing bad to say

Comment:
This is the second one I have purchased. Both work flawlessly.

Comment:
Plugged my power supply in and it showed me all I needed to know. Nice and easy to see if it was my power supply that was bad, or something else. I will use this baby a lot.

Comment:
Form, fit, function is great.

I had a computer that was not working, but didn't know if it was the motherboard or the power supply. I didn't want to spend money on another motherboard without knowing if the power supply was defective, so this device was perfect. I checked all of the power supply's connections, it was very simple with this tester, and they were all good. I still had to buy a new motherboard, but I knew for sure that this was the problem and not the power supply. This is a very useful tool for troubleshooting and highly recommended.

I haven't used the unit yet, but it appears to be a simple tester for voltages provided by the power supply. Nicely packaged.

Comment:
This tester paid for itself the first time I used it. It's multi-purpose functionality and compaq size makes it a tool to have for anyone that works on computers.

Comment:
Very quick tester for testing power rails. Good addition to the tool box.

Comment:
Exactly as intended. This product will indeed tell you of any failed voltage rails on a powersupply.... much faster than any voltmeter. If you work on computers this is a must have no-brainer.

helped with power supply issues

Comment:
this is a great device to use when you are repairing computers to see it their power supplies are good or not

Comment:
Wish I had this a year ago would have saved me $70

Comment:
Unit worked well, but feels kind of cheap. No complaints about the unit, it works well.

Comment:
A very handy tool to quickly check for power supply problems before taking the machine to the bench. Nice addition to my bag of toys

Comment:
Does just what it is made for.

Comment:
Simple to use. Tests voltage only, so don't think this will explain all the problems you might have, but, it works great if you need to know if there is power to a system.

You get what you pay for and for $14 I can understand why this item was on sale. The quality of the received unit was pathetic. When I squeezed the unit just enough so that I could plug in a PSU cord the entire thing lit up. I repeated the process and noticed that any pressure at all in certain places would cause all of the LEDs to light up. Over that it kept saying that I had no -5v on known good power supply units. Unless you're a modder and you want this just to see how they are made, then STAY AWAY. Spend 10 extra dollars and get something more reliable. PLEASE.

Simple to use and excellent value for the cost.

Ultra lives up to their name one more time. This test set is simple and easy to use. So far it is detecting problems without fail.

I was ready to dump my wife's computer after it quit. A routine check of power supply and bad connections, hard drive swap etc had no results. So it sat there until I saw an add for this gadget and I thought this would be handy and quick. It showed that my power supply was missing the PG signal, which occurs after all the voltages check out. My voltages checked out OK but the PG (power good) chip was bad. Saved me Hundreds!

Easy to buy, quick to ship, excellent price. Really nothing else needs to be said. Thanks.

Comment:
Good cheap price, I have seen it for twice as much other places. Works great and is a nice addition to my tech toolbag.

it's got lights and connectors for lots of different connectors from various power supplies and seems to work well. i've only used it on a couple of supplies and it's reported correctly. the thing i'm not too sure about and the chin-glish manual is not very clear on is whether this thing is actually putting a load on the supply or just testing the voltage levels. it says it's rated at max 1000w supply so i'm assuming that it's loading the supply and it can only load up to 1000w but still not sure cause you would generate some heat pretty quickly getting up to 300w and above if it were loading supplies to their limits. i've seen supplies that show correct voltages but once loaded down they drop out. other than this loading thing it's a simple way to tell you if the supply has all of it's voltages on various connectors.

Does everything you need it to do.

Does not work at all,but it's not worth the return shipping.Unhappy customer for sure.
