Ultra 20/24 Pin Power Supply Tester

Comment:
Worked as I had planned. Condemned suspect power supply. New supply worked.

Terrific for a quick test to determine if problem is in the PSU or on the MB. You won't need to drag out the DMV test leads and best of all you won't need another hand.

This device does work, but I need to know if power is low (I could use a multimeter) Spend another $10.00 and get a Manhattan digital tester. Oh yea, and if you have never used one of these before, plug the 20 pin connector in first, and leave it plugged in for the rest of the tests. Also, some 20 pin plugs have the white (ground) wire but it is not used Via circuit board (Read the output sticker on PS)and will test as a no light on neg 5.

For the money this is the best quick check tool.

Since I received the item I was able to successfully test my existing power supply and another that I bought to upgrade it with. The upgrade was doa and this tester proved it. Very happy that I was able to test and send it back for a replacement that worked.

for the price it does a great job. led shows you when you have power

Comment:
I have a tester that I bought years back for about the same price; but it does not check all the connections on the psu! This is great! Good price and just what the doc ordered! Thanks!!!

Comment:
It does what it was designed for.....Test a power supply to see if it functions. It isn't a test bed! It does a good job.

You won't find an easier way to determine if you're non-booting computer is a dead power supply or dead motherboard. That alone is worth the price, but it's also great for checking currently unused power connections before buying an add-on part, etc. If you need precise voltages though, get a multi-meter.

Works great!!!

Comment:
Its not 100%, I mean you cant load test a supply or check for excessive ripple but in a pinch it will show you if your getting voltages. Its a down and dirty fast first step. I only needed it for that andy thing more and your going to need a test bench. Good for field tech's. Im lazy to take out a meter and short the enable pin. ;)

Works great. Showed problems with two of my power supplys that I thought were good.

Comment:
I thought I was having problems with my power supply but this little gem showed that everything was working. It's a very handy item and will be a handy addition to my toolbox.

Comment:
Invaluable tool for builders. Lets you eliminate the PS when problems crop up.

Comment:
I bought this tester when i purchased a barebones. I used it right away. Works great.

Comment:
Unit works as advertised. Has solved two problems already with PSU's. My friends were grateful to have their computers repaired.

Comment:
If you are like me and have people constantly needing help with computer system, this one device saves so much time in checking out a power supply. Plug it in and boom You either work or you don't.

Comment:
I bought this tester to check out an extra power supply I had before I used it in a new system. All seemed to go well, so far...

Comment:
About as basic as they get for today's PSU's. The downside is that it is misleading. I've gone through countless PSU's at work, this thing passes every one of the failed ones. I ended up getting a 2 for 1 deal, both perform the same. Upgraded to a different brand.

Comment:
I bought my first one in a kit never gave it much thought after i started using it i went to buy another one for a travel kit oth work great

Comment:
It's quicker then using a volt meter on a Power supply but not much more.

Comment:
Really good tester

Comment:
I used it on a power suppy that did not work in computer and it tested ok. I checked a good power supply and it smoked it. The instructions are not good.
