LED tester for PCI-Express PCIE ports - with 12V/2A power supply

Allows you to test whether all contactors in a PCI EXPRESS slot are active and in good condition. Instant visual test thanks to a tray of LEDs.
For all equipment with a PCI EXPRESS port. Note that due to its size, it will not always be possible to test PCIE 1x ports, as the tester is primarily intended for testing the graphics card port (16x and above).
Operating mode:
- Position the tester on the PCI EXPRESS port to be tested, and supply it with an external 12V power supply (with a 2.5x5.5mm plug). EXTERNAL POWER SUPPLYED,
- Press the small button on the tester and view the LEDs. They should all have the same brightness: a diode that's too dark may indicate an open circuit, while one that's too bright may indicate a short circuit,
No special skill is required, just the touch of a finger. The motherboard itself does not need to be powered to test the viability of the contacts.
