Question about Ugreen USB C – USB C

If I have read this correctly, the PSVR2 cable is already 4.5 metres long. I would be careful with extensions, because depending on the quality and data rate, the transmission can no longer be guaranteed.

I don't know the specification of the PSVR2 either, but for high data rates I would use an "active extension" with a repeater.
If no one has tested it before you, I would just give it a try.
