Can I use these two displayport cables safe?

[Flying Sausages]

So I did my research and found that 19 or 20 pins are no good because it brings power back to the gpu which can potentially fry your gpu or your computer. I bought these two off Amazon today CyberMonday so I wonder if it is safe to use?

20-pin is the bad one (20th pin is DP_PWR and supplies 3.3V 500mA for stuff like active adapters to use).

 

VESA certified cables should only be 19 pin, the exception being:

DP official specification says on page 147 [2]:

3.2.2 DP_PWR Wire A standard DisplayPort cable must have no wire for the DP_PWR pin. Only captive cables supplied with cable powered Branch Devices or cables permanently attached to Sink Devices are permitted to have the wire for DP_PWR. These captive/attached cables must have a standard DisplayPort plug connector (as specified in Section 4.2.1) on one end only. The other end must either be permanently attached or have a custom connector.

As both of those cables you linked (which are quite overpriced) claim to be VESA certified, so neither should have a 20th pin.

Since you say both don't have 20 pin then it is safe to use right?
