What is the problem with the 3.3v?
Hi Guys,
I bought this power supply but when I checked it using my cheap PSU checker, the 3,3v LED didn't light up. Could you please verify the readings? I'm unsure what the correct values should be and want to know if it's faulty or not.

The display indicates 3.3v. It might be that the tester is faulty.
I noticed it mentioned 3.3v on the tester, but I don't want to risk damaging my components. Maybe I should check another PSU and see if the LED indicators work.
The illumination on the left is used to verify Molex and SATA connectors. It accurately shows that the SATA port lacks a +3.3v supply, which is typical for older power supplies. The display confirms a 3.3v presence on the 24-pin connector.
Well,
those inexpensive testers merely verify voltage without load. It's more about confirming all components are present rather than testing functionality. If the readings are incorrect, a buzzer will alert you. You might want to check the seller's description first if the price seems too low for a manual.
If you connected a Molex and the 3.3v doesn't activate, that's expected since those lack an orange wire.
When your PSU's SATA power connectors include the orange wire, the 3.3v LED should illuminate, but any modern SATA drive with power disable will not work unless you remove that wire. Alternatively, use a Molex-to-SATA adapter.
Plugging the SATA connector in and seeing no activation indicates compatibility with modern SATA drives.
