## Description

desertcart.com: Computer PC Power Supply Tester, ATX/ITX/IDE/HDD/SATA/BYI Connectors Power Supply Tester, 1.8'' LCD Screen (Aluminum Alloy Enclosure) : Industrial & Scientific

Review: Reliable and Convenient PC Power Supply Tester. - I have been using this PC power supply tester for a while now and it has proven to be an invaluable tool for both troubleshooting and assembly. It supports a wide range of connectors including ATX, ITX, IDE, SATA, PCI-e, and EPS, making it compatible with virtually any desktop power supply I have worked with. The 1.8-inch LCD screen is bright, clear, and easy to read, displaying voltages on each rail accurately. It immediately alerts you with both visual warnings and an audible beep if any voltage is outside the standard range, which makes identifying faulty units quick and straightforward. The tester’s aluminum alloy enclosure is sturdy, lightweight, and feels premium compared to most plastic testers on the market. The unit also includes a protective film over the LCD to prevent scratches during transport and storage. Its compact size makes it easy to carry or store in a toolbox. I appreciate the thoughtful design: each connector is clearly labeled, the device powers on instantly when plugged into a PSU, and it does not require any batteries. I have tested multiple new and older power supplies with it, and the readings have always been consistent with my multimeter. For anyone building, repairing, or diagnosing PCs, this tester is a must-have. It saves time, reduces guesswork, and ensures that your power supply is functioning correctly before connecting expensive components. Highly recommended for both hobbyists and professionals.
Review: PSU Tester tool to check dead PSU - A PSU tester is a useful, inexpensive “first-pass” tool. It’s great for basic checks: dead PSUs, obviously faulty units, or ensuring rails nominally output correct voltages before building a PC. Pros: Safe and easy to use Affordable & handy for basic diagnostics Cons: Only tests idle output, not under-load behavior No check for power quality

## Features

- [Beep Alarm] -- When your power supply test value is beyond normal range, the Power Supply Tester would issue a buzzer alarm, Easy to Know
- NOTE: The voltage of 20pin / 24pin connectors is displayed by the LCD Screen, as "+3.3V", "+12V1", "+5V", "-12V", "5VSB", "PG" (except "+12V2" on LCD Screen); The voltage of PCI-e 6P / 4P / EPS P8 connectors is displayed by the LCD Screen as "+12V2"
- NOTE: The voltage of IDE (HDD), Floppy, SATA connector is displayed by the lights on the left of the power tester, IDE (HDD) connector is displayed by "+12V" & "+5V" lights; Floppy connector is displayed by "+12V" & "+5V" lights; SATA connector is displayed by "+12V", "+3.3V" & "+5V" lights
- NOTE: When you test the SATA connector, please confirm how many wires your connector is. When the 5-wire SATA connector is normal, the tester will light up three LED lights "+12v", "5V" and "+3.3v". When the 4-wire SATA connector is normal, the tester will only light up two LED lights "+12v" and "+5v"

## Questions & Answers

**Q: How does the tester turn power on? doesn't an atx power supply require a 'signal' from the mobo to the ps so that it turns on?**
A: The MOBO 20/24 pin and the 4/8 pin need to be plugged in at the same time for power supply to activate.

**Q: Can this be used for proprietary Dell “8pin” motherboard psu’s?**
A: It depends on the wire configuration (yellow and black). I believe this will test an eight plug with four yellow on one side and one yellow and 3 black on the other side. Keep in mind the 20 pin plug has to be installed and the power supply turned on.

**Q: What does it mean when the ps-ms area reads zero and keeps beeping continuously? everything else reads ok tho. am i good to go?**
A: Could be for Continuous Beeps - Memory or Video Failure. If you are just testing Power supply, it maybe defective. If its the PC itself, you should have your hardware tested. There is various hardware testing software tools out there to assist in that. Would need more info to go on to answer your question fully. Well if you are in Florida near us. We could test and diagnose it for you. WWW.Brighter-Tech.com

**Q: Can this power supply tester act as a psu jumper?  thanks!**
A: The jumper is internal to th tester.  the PS turns on when the 20/24 pin connector is inserted.  That's why this connector needs to be on when the 4-6-8 pin connectors are tested.

### ⭐⭐⭐⭐ USeful voltage checker
*by M***E on May 12, 2022*

I opened up the unit for you guys so you can see what's inside. The microcontroller or measurement IC's are underneath the display module so I can't tell what they are. The unit appears to be well-made and the soldering is OK. The unit operates when the main power connector is plugged in and the power supply is turned on. If the 4 pin MB power connector is not plugged in, the unit will show, for the +12V2 voltage, "L.L" and the unit will beep. The beeps are very quiet. You should only connect, at any one time, only one of these three power plugs: SATA Floppy (does anyone have a floppy drive these days?) 4 pin Molex This is because they are all wired to the green LEDs at once and connecting more than one power plug at a time in parallel wouldn't mean much. This isn't explained in the documentation, which needs a second round of editing to make the operation of the device clearer. The three green LEDs indicating 3.3, 5, or 12 V from the floppy, SATA, and 4 pin Molex power connectors are not an indication of a measurement "good" signal from an active device that is "measuring" the voltages. Rather, they are simply wired straight to the incoming voltages from the connected SATA, Floppy, or Molex plugs with a series current limiting resistor. It is not a "measurement" in the sense that the other voltages indicated on the LCD display are being measured. It is just a "dumb" indication that a voltage sort-of close to the required voltage is present, or that the wires are actually connected properly. The 3.3, 5, or 12 V lines could be off by a bit and the LEDs would still light up, but they would be brighter or darker than they would be with the correct voltage applied. You can look at the main LCD if you want to know the exact voltage coming out of those power supplies. Also, this measurement unit does not load the power supply and draw a lot of power like a real operating computer will when plugged into the power supply. So, if the power supply has problems maintaining proper voltages operating under a load, this unit will not tell you that. But you could infer that problem if all the voltages showed OK using this tester, but the PC still won't run properly (could be many other problems also ...).
