Features

Features
This product is a simple tester for switching power supply. It makes it easy to test the power supply output.
1. Turn-on your power supply.
2. Plug-in your 24 pin power supply connector to mini tester
3. Check LED light it ON or OFF
(+5V. +12V. +3.3V. -5V. -12V. +5VBS. PG)
- If the power output is working, the LED will light and you will hear a sound
- If the power output fails, you won't see the LED light & no sound
4. Plug the HDD con, check +12V, +5V
5. Remove HDD, Plug p4(p6/p8)con, check +12V
6. Remove p4(p6/p8)con, plug FLOPPY con, check +12V, +5V
7. Remove Floppy con, plug SATA con, check +12V, +5V, +3.3V

4 out of 5 eggsWorks as advertised

Pros: This device works as advertised.

Cons: The SATA port seems a little flimsy and it's a little unnerving to plug 12V/5V directly onto copper pads, but it seems to work fine for now. I suppose time will tell if the pads pull off.

I also wish the SATA port was keyed. I guess it is in the sense that you can't plug a SATA connector on backwards because the sides (at least on my device) are spaced as to restrict such backwards plugging. But you can still get the SATA plug in there just a bit cross-ways (hey, it was dark, I couldn't see well), which, given the different voltages being output could potentially short across the copper pads. Or at least I feel like it could.

Other Thoughts: When reviewing this device before purchasing it, I kept seeing reviews about it not providing a load test. However, I don't see anywhere in the spec that it purports to perform a load test, and for $14 I wouldn't expect it to. It provides the most basic voltmeter function and lights up when, presumably, the output voltage is within spec of the rated outputs. Now, I'm not sure how it determines the threshold voltages of good/bad, but I bet there are some industry specs for this. Maybe it goes by them, maybe it doesn't, but if I wanted to know the actual output voltages, I could break out some alligator clips and use an actual volt-ohm meter. If I wanted to test load then I would invest in something that claims to test such a function.

5 out of 5 eggsWorks as Advertised

Pros: PSU tester is a handy tool for PC DIY builder. Used it in conjunction with a PC that was having possible bad ram, psu, or mobo type symptons. Tested ram: Ok, Tested psu using tester: Ok. Bad mobo. Close inspection revealed leaking caps.

Cons: None really

Other Thoughts: Very simple tester for the $. Easy to use. Instructions are posted on top of the tester so even a caveman could use it. Tester came packaged in padded yellow envelope and arrived not damaged.

4 out of 5 eggsGreat, cheap little device.

Pros: Worked like a champ the very first time. Helped me diagnose a spontaneous grounding issue in my PC. Thought my PSU had died, but nope, this little gem saved me at least $100. Has all of the features I needed at a reasonable price. It's not high end, but that's ok for the price.

Cons: Build quality is just slightly too cheap for the price, but it holds up well to occasional, light usage. Probably won't be a problem for the majority of casual users, but if you're looking for something that is industrial grade, keep looking.

The instructions are pretty much a waste of paper, unfortunately.

Other Thoughts: Nice little device. Really like how relatively compact and simple to use it is. Helped me out in a pinch!

5 out of 5 eggsgreat power supply tester

Pros: worked great out of the box. it was easy to understand and it let me test all of my PSU's plugs.

Cons: if you leave it connected to the PSU to long it start to make a really loud ringing, it says on the power supply tester that if your PSU is working it will emit a sound, but it's to loud and hurt your ears, they could have made it more subtle

Other Thoughts: great for the price. i needed to test a new power supply that i bought from newegg not because i though it was DOA but to get all my other parts ready for a build im just waiting on newegg to start selling the ivy bridge processors

5 out of 5 eggsAlmost worked Too Well !

Pros: Well made. Powered by the 20 or 24 pin ATX connector and gives you a green LED when proper voltages are present. Has separate connectors to test SATA, floppy, 6pin PCI-E, and 4/8 pin connectors. These are clearly labeled. Instructions list which voltages should be present for each of the other connectors. You cannot insert the connectors improperly. Perfect for the average user and routine use may prevent you from damaging a motherboard or other device.

Cons: No case. (Save the box to protect from dust) If you want the actual voltages spend another $10 for the Rexus PST-3 version.

Other Thoughts: When I received this the first ATX power supply I tested was in the same order. It showed the -5v was not working. I tested an older ATX power supply and -5v was working. I thought that the new one was defective and started filling out a NewEgg RMA. I was charged $15.85 to print a UPS return label. (To save time I was going to reorder the power supply) Fortunately I did a little research and learned that the -5v was dropped when ATX 1.3 was adopted April,2003. It was only needed for ISA slots which are obsolete. Having one of these available can save you both TIME and MONEY.

5 out of 5 eggsWorks

Pros: Provides led indicators when testing power supply. Works great!!

Cons: None

Other Thoughts: I use this at work frequently and have found faulty power supplies with it. This sure beats having to test a PC with a spare power supply and helps rule out one that isn't operating properly.
