💻 Optimal Shop 20+4 Pin LCD Computer Power Supply Tester - Reliable SATA IDE HDD ATX ITX BYI-Black Review

Bought to test my PSU on an old server I'm using that just died on mine. Thought at $16 it would be worth getting this rather than trying to replace parts with trial and error. I've never used any of these before, so I wasn't sure what the results should be. The package says it includes; Power supply tester, user manual. If you name the 3 lines on the back of the packaging with the title "Operating Methods" as operating instructions, you lose a star. But a quick search online turned up a video…

Lost the other one so I bought it again. great block. Note: Connect the 24-pin cable first. Leave it connected while you test other 4/6/8 pin connectors, SATA and Molex. You will get a blinking LL on +12V2 if no 4/6/8 pin SATA or Molex connector is connected. The voltage shown at +12V2 corresponds to the 12V line of that connector. don't know how to properly use this well-designed tool.

One of the machines that stopped working. And a replacement for this car. But the machine would not turn on with the new power supply. I understand the board is dead. Currently. I built a nice retro computer. Some parts are expensive. At a total cost of around $2,000, I didn't want to risk adding a bad PSU and frying it. This tester performed just as well with the new power supply. The OLD power supply showed all voltages but had an "error" and the voltages fluctuated a bit. The new power…

This is actually a very good PSU tester. The key to getting the most out of it comes down to user understanding, which I'll explain in this review. Plug and leave it there while cycling power. I mention this because holding or moving around the power supply tester will give incorrect readings. Next thing I saw in the reviews is something else that you unplug your PSU and then plug in the next connector, be it SATA, Molex, 4-6-8 pin connector etc. "hot-swap" so always switch power supply tester…

It's a nice little device and it works as advertised. Used to check Corsair CX430M, 24 pin connector and 4 pin CPU connector. The case looks like aluminum, the plastic connectors are solid, the LED numbers and indicators are clear, no problem. It runs on external power from your AC adapter, no batteries are required. For the money this is a bargain and perfect for quick measurements. It beeps when expected performance is missing or out of specification. There are no on or off switches, if you…

I had a problem with my computer and figured it was the power supply. I bought a power supply from HP and this meter for easy testing of the power supply. I measured the old PSU (weeks before I got the new HP PSU) and it confirmed that the 12V on the main ATX connector was bad. When I received a new share. Surprise! This counter showed that the new shipment had the same problem. I took my trusty old HP DVM and measured the consumables. another surprise! Both were good. 12V was good. This…

Provides digital reading of voltage from power supply, has connectors on all 4 sides for different cables. Great for identifying disconnected or faulty power supplies. Normally, computer power supplies either run at the correct voltage or they don't. It is fairly rare for a power supply to drop under load or fail after it has been working well.

I'm a firm believer in build quality and for under $20 I don't feel cheated at all. It's made from a solid aluminum body and doesn't have that cheap Chinese feel you get with a bunch of cheap electronics like this. I've been in IT for 19 years now and truly something I would still buy if I saw it in person. In action it works as expected. I plugged and unplugged various ports while it was powered on and it had no problem locating/matching the status of the inputs (connected/disconnected)…
