If you buy HOUSINGS, you need these: 50x ATX crimp terminals MALE Minifit-Jr for ATX, PCI-E and EPS, made for 16 AWG and 15 AWG (1.50mm²).
MALE crimp terminals are always used for HOUSINGS.
The difference to the standard Minifit-Jr AWG (17-18) MALE version can be seen in the second photo. The only difference is the length of the conductor "wings", which wrap around the conductor of the wire when crimped. Both size versions are 100% compatible with all housings and mating terminals.
