Featuring a sharp 1.8'' LCD screen and audible buzzer alerts, it delivers precise voltage readings up to 500W output, enabling quick identification of power supply faults to keep your PC running flawlessly. ## Description Computer Power Supply Tester with 1.8'' LCD Screen Operation method: A. Insert the power 20pin or 24pin and P4, P6 or P8 plug into the corresponding position of the power tester. (if the 20pin or 24pin interface tester alarms and displays “LL”, it needs to plug in 4P! Please make sure 4P is inserted in 4P position! ) B. Turn on the power supply, at the same time, "didi" sounds twice. If the values of each group do not flash, it indicates that the power input of this power supply is normal. C. The voltage of IDE / SATA / P6 / P8 interface is displayed by the three lights on the left of the power tester. If their voltage is normal, the three groups of lights (+ 12V, + 3.3, + 5V) will be on. If the light is not on, it indicates that the interface line group is faulty. D. If the voltage signal of a circuit is not detected (such as 20pin or 24pin connector) or the detected voltage exceeds the normal range, the buzzer will send out a warning sound of "di di" for a long time, and the corresponding voltage or PG value display status is flashing state, it means that the power supply is a fault source! Special reminder: do not use hot plug! This is basic knowledge!! Note: 1.The power tester has no battery and is completely powered by 20 pin or 24 pin interface, if there is no 20 pin or 24 pin interface powered, tester screen will not light up and the value cannot be read. 2.The Product Screen Has Scratches？Because the LCD screen is easy to scratch, we put aprotective film on It, if you think It's not beautiful and useless, you can tear it off by yourself. 3.The protective film of the screen fits very well and is not easy to tear off. Please operate carefully to avoid scratching the LCD screen. 4.Please do not plug the interface in the wrong position or reverse, which may cause the power tester to smoke or damage your power supply. ## Features - Item Category: System Power Device - Item Trademark: Fuhengli - manufacturer: Fuhengli ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076CLNPPK | | Brand | Fuhengli | | Compatible Devices | Personal Computer | | Compatible devices | Personal Computer | | Connector Type Used on Cable | SATA | | Connector type | SATA | | Cooling Method | Air | | Form Factor | ATX | | Form factor | ATX | | Item Dimensions | 12.4 x 6.6 x 1.6 centimeters | | Item Weight | 3.1 Ounces | | Item height | 0.63 inches | | Manufacturer | Fuhengli | | Model Name | Fuhengli PC Power Supply Tester | | Model name | Fuhengli PC Power Supply Tester | | Output Wattage | 500 Watts | | Output wattage | 500 Watts | | UPC | 761330542553 | | Unit Count | 4.2 Ounce | | Wattage | 500 watts | ## Product Details - **Model name:** Fuhengli PC Power Supply Tester - **Brand:** Fuhengli - **Compatible devices:** Personal Computer - **Connector type:** SATA - **Output wattage:** 5E+2 Watts ## Images ![Computer PC Power Supply Tester, ATX/ITX/IDE/HDD/SATA/BYI Connectors Power Supply Tester, 1.8'' LCD Screen (Aluminum Alloy Enclosure) - Image 1](https://m.media-amazon.com/images/I/7177m9v4lkL.jpg) ## 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. ## Frequently Bought Together - Computer PC Power Supply Tester, ATX/ITX/IDE/HDD/SATA/BYI Connectors Power Supply Tester, 1.8'' LCD Screen (Aluminum Alloy Enclosure) - ARCTIC MX-4 (4 g) - Premium Performance Thermal Paste for All Processors (CPU, GPU - PC), Very high Thermal Conductivity, Long Durability, Safe Application, Non-Conductive - ARCTIC EAGLE Anti Static Wrist Strap, 11" Anti Static Wristband Grounding Bracelet with Alligator Clip and Extendable Long Cable, Fits Wrist Circumference 6" to 8.5".
