12vhpwr to 2x8p VS 12vhpwr to 3x8p/4x8p

it is often asked and thought that is 12vhpwr to 3x8p safer than 12vhpwr to 2x8p? or more 8p means more safety?

the answer is no, what decides the cables' safety is not how many 8ps it has, but the wire quality and the pins' quality. let us try to explain in an easy way.

-take a 600W gpu as example, if we are use a 12vhpwr to 2x8p cable, it means each 8p will have to load max 300w 25A, each 8p has 3x12v wires, and each 12v wire has to load about 100w, 8a. so if a cable can meet above standard, then it is ready for 600w, and that is why we see more 12vhpwr to 2x8p modular cables now as there are more better quality material than before.

-the power through the cable is decided by your psu and GPU, the wires are just a "bridged" so they can't decide or increase the power for your gpu when it needs. "they can load more power when your gpu needs and psu can". As long as this "bridge" is enough to load max 600w power, then 2x8p will work. and on the contrary, if this "bridge" is not enough to load that many power, then even 6x8p will not work. if one day, the cable quality and pins' quality improve, we are not superised to see 12vhpwr to 1x8p which is rated for 600w.

-so when the material meets all the standards, usually we make 12vhpwr to 2x8p. first it is rated for 600w. second, 2x8p can help save some room compare to 3x8p. moreover, some psus like corsair type 5 psus, they have smaller plugs and we have to make 12vhpwr to 2x8p.

Hope this can be helpful for you.
