Power Supply to LED strip, faulty?

So I'm using a supposedly 5V 6A power supply, but when connected to the Arduino and LED strip GND + the 5V to the LED Strip, the blue light on the brick does not light up, so I'm guessing it's not working as intended. What I did was remove the DC plug and wire these directly to the strip (and GND to Arduino), does that make the PSU not work?

Thanks

Thanks for the reply, I opened the power supply and it was all burnt up, I'm going to try and get another one with similar specs.

Thank you both for your help! Will mark as solved since it was indeed faulty.
