CaseBuy LCD EZ IIIWhen I first began repairing computers, power supply units caused me the most problems. When a PSU begins to fail, or is faulty out of the box, it is sometimes difficult to determine because the symptoms are similar to other faulty hardware components. One of the best investments I ever made was the PSU tester; until now. CaseBuy now offers a digital LCD display on the EZ Power Supply Tester III. Benchmark Reviews shows you just how important this tool is, and why every technician, overclocker, enthusiast, and even gamers could benefit.
The power supply industry is filled with misdirection and illusion. Do you really need a kilowatt of power, which is enough to power an entire household full of appliances, or do you just need to replace your suspect power supply unit? Sometimes the answers can be confusing, because marketing hype has done a great job of convincing you that bigger is always better. This is why I use tools to assess the condition of all the equipment I test. CaseBuy has been in the business of offering simple Power Supply Testers for quite a long time now. They began with their original EZ Power Supply Tester i (1), which was designed for 20-pin ATX power supplies. Shortly thereafter the 24-pin version was released, and the EZ Power Supply Tester ii (2) was born. These two testers are great, because they are super-simple and give me immediate feedback on the power supply unit. But now CaseBuy has done one better, and released the LCD EZ Power Supply Tester iii (3). The EZ Power Supply Tester line of products offered by CaseBuy is based on the Top & Tech Enterprises line of products. The EZ Power Supply Tester ii (2) is manufacturer part number PS-124 and SKU 14907. The LCD EZ Power Supply Tester iii (3) is manufacturer part number PS-224 and SKU 14909. Top & Tech Enterprises is an production/engineering company and licenses these products to only a few select distributors, such as CaseBuy and CoolMax. About the Company: CaseBuy Tech CorporationCaseBuy has been in the industry for several years now, but you might not have realized it since they are based in Asia. With two locations, CaseBuy offers power supply and computer case products to partners.
