You would need to use 7 of the pcie ports just on the GPU's, so how are you powering the risers???
Splitters are fine to split ONE pcie port to two for connecting two risers to each, but anything more than that is begging for trouble.
Ideally you need to have enough pcie ports on the psu to power all GPUs and risers. In a pinch you can use molex powered risers, but do not use any molex-pcie adapters that come with risers, those are a fire hazard.
As a general rule of thumb, do not exceed 80% of the rated load on the PSU for long term operation, 75% if you dont have adequate cooling.
thank you
so its ok to use the Molex 4-pin cables to power the risers instead of 6-pin cables and reserve those for the cards only ?
can i use the same cable strand for multiple risers or one riser per cable ?
finally i did the math for your last mentioned point: 5 cards x 135~w per card (of course they are power limited) = 675 W total | and 75w per riser x 5 risers = 375 W
total power needed 1050 W
are you saying i can Not use a 1000w PSU or even a 1050w PSU for 24x7 mining ??
i must admit the two models i have my eyes on are:

kindly advise need to decide soon, thanks...
thanks,
