Package Includes: 1 x Kingwin DIGITAL LCD POWER SUPPLY TESTER Review: Will not fit Lenovo Power Supply - Purchased this tester for a Lenovo TS-140 Think Server. 14 pin power connector on Mother Board. No instructions on how to hook this tester up. Turns out there is a adaptor cable required for Lenovo mother boards. Why not just bundle the tester and adaptor and save the grief? Ordered the adaptor. If it works, still one star for inconvenience and poor marketing. Review: cheap enough to buy and keep waitingfor future uses. proved my big cpu local store lied. - Multiple ports for different testing. Bought mine to test a known dead power supply. Funny was the big local pc store just said they did a complete test blah blah on yet again a failed component. Long story short on big local - 5 items purchase and 5 items returned as failed - brand new. hd lasted 15 minutes and data recovery store confirmed doa. Got this to test and funny the customer was right and again a return and buy elsewhere. One them tools I have in arsenal that is there for when you need it even if used only once. ## Features - ✔️Comprehensive Power Supply Testing: Efficiently test a wide range of power supply units (PSUs) including ATX, ITX, IDE, HDD, SATA, and BTX, ensuring your components are functioning correctly. - ✔️Digital LCD Display: The clear LCD screen provides real-time readouts of voltage levels, allowing you to easily monitor and diagnose potential issues with your power supply. - ✔️User-Friendly Interface: Designed for both beginners and professionals, this power supply tester is easy to use, with simple plug-and-play functionality that requires no advanced technical knowledge. - ✔️Accurate Voltage Readouts: Get precise measurements of various voltage rails including +12V, +5V, +3.3V, and more, ensuring your power supply is delivering the correct voltage to your PC components. - ✔️Portable and Compact Design: Lightweight and compact, this tester is easy to carry and store, making it an essential tool for system builders, repair technicians, and PC enthusiasts. - ✔️Multi-Connector Compatibility: Equipped with multiple connectors, this tester supports a wide range of power supply types, ensuring versatility and convenience for various testing needs. - ✔️Quick Diagnostic Results: Save time with fast, reliable testing results that help you quickly identify faulty power supplies, preventing potential damage to your computer components. - ✔️Safety Features: Built-in safeguards protect against short circuits, overvoltage, and other potential hazards, ensuring a safe testing environment for both the user and the equipment. - ✔️Durable Construction: Made with high-quality aluminum materials, this power supply tester is designed for long-term use, offering reliable performance even with frequent testing. - ✔️Ideal for System Builders: Perfect for DIY PC builders, IT professionals, and anyone needing a dependable tool for diagnosing power supply issues in desktops, servers, and more. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07VXSFXP1 | | Brand | Kingwin | | Brand Name | Kingwin | | Color | black | | Colour | black | | Compatible Devices | Personal Computer | | Customer Reviews | 4.6 out of 5 stars 610 Reviews | | Global Trade Identification Number | 00812348013662 | | Included Components | Item | | Item Dimensions | 7.6 x 5.1 x 2.5 centimeters | | Item dimensions L x W x H | 7.6 x 5.1 x 2.5 centimeters | | Manufacturer | Kingwin | | Measurement Type | Voltmeter | | Min.

Seems good but there's no instructions or manual. Can you provide something?** A: Just plug the large plug to large jack on the tester. use the key to connect your PS will have either 20 or 24 pin. once thats in the lights will light if the voltages are there. Most PS units no longer use -5v so that prob won't be lit. with the large connecter still attached plug the additional connectors one at a time in to check the voltages on them. **Q: What is the indication if the ps is dead?** A: Simply either it doesnt work, or a reading is way below of the parameter **Q: Does this have a sata polarity check? Sata moulding is designeded to fit only one direction. Some testers unfortunately allow flipping both directions** A: This tester has SATA polarity check. Though the SATA cable can be conected both ways on the tester, there is onle one position in which it will work for testing. Even if you connect the SATA cable wrong at first, it won't damage the unit because there are testing contact only on a side of the SATA tester, and also the PCB is correctly isolated in case it is connected wrong. It really helps and the unit is high quality, by the way. **Q: Dell power supply has remote turn on. How do you activate power supply for testing? There is no switch on power supply, pc turns on by button on front** A: i believe this turns on power supply once it's plug in all my power supplies have a switch. so if yours don't have one it should turn on automatically once plugged in ## Customer Reviews ### ⭐ Will not fit Lenovo Power Supply *by F***S on 7 October 2021* Purchased this tester for a Lenovo TS-140 Think Server. 14 pin power connector on Mother Board.
