Powerline cable support 3a output?

Just wondering if the Powerline USB cable line can handle 3a output? Trying to power my Raspberry Pi and I’ve gotten 3a and a 3.5a PSU but I noticed the cables are thin and don’t seem to power my power hungry Pi.
Any help is appreciated,Thanx

What is the maximum draw of your Raspberry Pi?

The min PSU you can use is 2.5 but since I have LED,fan and a HDD I need more power.
