USB card V2 - PPA Studio Paul Pang - Power supply

Normally PCIe cards are powered via the PCIe lane of the mothermoard.

This is never the best solution for high-end audio reproduction.

The power of the motherboard is contaminated and will result in a higher noise floor.

Therefore the PPA Studio Paul Pang USB card V2 is powered via a 4-pin Molex (5V / 2A min.).

This results in clean power. Music will have more tranquility, clarity and a blacker background.


External Power Supply

Audiophile USB card V2 - PPA Studio Paul Pang - bracket for eternal power supply

For best result you should power the card externally. Optionally you can order an extra bracket & high-end power cable so you could use an external power supply.

This bracket is placed on the back of your case.

You have the choice between a 2.1 mm DC input jack or 2.5 mm DC input jack. This connects an external (lineair) power supply.

At the other side there is a 4-pin Molex. This connects the USB card.

With this option you can use an external lineair power supply like the HDPLEX 200W LPSU. This will give you a much better result than the internal power supply of a PicoPSU.

Please pay attention: a higher voltage than 5V could damage the card and will not be covered by warranty.



Loiw jitter TCXO

TCXO stands for “Temperature Controlled Crystal Oscillator”.

The TCXO clock on the Paul Pang USB card V2 will generate a much better timing and a much lower jitter value than the standard clock of your computer.

It will output a much better signal to your external DAC when compared to the regular USB outputs on your PC.

A better signal will be sent to your DAC.
More tranquility
More “analog”
Sound is more “smooth”
