## Questions & Answers

**Q: Does this tester provide any load?!? Testing voltage in an open (or near-open) circuit isn't all that useful.**
A: No.  This tests the Power Supply Unit itself; it does not test any other computer component.  To use this tester the power supply is disconnected from the computer components (Mother board, Hard drive, video card, floppy drive, DVD burner, etc.) and the PSU cables connected to the tester instead.  When the PSU is switched on, the tester will read the current being supplied by the PSU to the various power cables (24 pin, P4, P6, P8).  As you may know, improper current can wreak havoc with electronic systems. For example: This tester told me that the current being supplied by a PSU to one of its power cables was borderline minimum and fluctuating. A close examination of the PSU revealed that a couple of capacitors were swelling and barely beginning to split and leak.  Hope this helps.

**Q: The piece of cardboard says there is a user manual.  However there is only the piece of green cardboard.  Is that all there is?  Any online sources?**
A: I bought this for my hubby and he tells me the green cardboard is all you get...I didn't see any other info online either, sorry. My hubby tested a power supply that he knew as good to see how it reacts/reports. Hope that helps,  Jeanne

**Q: Is the sata connector polarized?**
A: I have no idea. But I do know that I used this 3 times, twice with a more expensive tester and this was wrong twice. After a few times this thing shorted and died DX

**Q: on mine pg is blinking what does that mean? thanks tom**
A: I believe that means that is bad (or you don't have it puged in correctly).  Everything should give you a solid number with little values changing.  As long as you don't get a "DuDu Ring" or "DuDu Long Buzzer" everything is good.  If you do a internet search, there are a couple of videos out there using this model tester.

This is actually a very good power supply tester unit. The key to getting the most out of it depends on a users understanding of it, which I will be explaining in this review.Find a place where you can set it up to hook up your connectors both the 20/24 pin and the 8 pin connector and leave it there still, while you turn your PSU's on and off switch. I mention this because holding it or moving around the power supply tester will give you incorrect readings.Next, something else that I haven't seen mentioned in the reviews is you turn off your PSU and then hook up your next connector, whether it be the SATA, Molex, 4-6-8 pin connectors, etc. The connectors weren't meant to be "hot-swapped" so always turn your power supply tester off before going to your next plug.The PG rating means "power good" and it needs to be between 100 ms to 500 ms. If you are getting a 0 ms, that particular plug is dead and you can't use it anymore.The LL value means the voltage is too low and HH means the value is too high. You'll also get a buzzing sound with either a PG - 0 ms, LL, HH rating, so pay attention. This indicates the voltage is out of tolerance for a peripheral and you aren't getting any power at all, aren't getting enough voltage or are getting too much and could be frying your equipment, respectively.The tolerance range is ideally +/-5% (+/-10% for the -12v rail) of what the voltage is supposed to be giving, but here are the max ranges I've found, so if your number isn't in this range you now know what to do with your PSU.+12v - 12.5v+5v - 5.3v+3.3v - 3.5v-12v - 13.2vYou can indeed test this unit under a load, but you have to take a paper clip and you'll need to connect it to your main 20/24 pin connector. Connect as many peripherals as you can and look for the PWR_ON green wire on the 20/24 pin connector and connect one end of a paper clip here and the other to a black ground wire. This starts the PSU with everything running.That's it, folks, a review that clearly explains how to use this tester.Have a good day.
