I'm running two batch 5's off of one thermaltake smart 800W, 4 PCI-E connectors.
How significant of a risk do I run by overclocking my batch 5's to 250MHz? Temperature of the S3's are fine (44/43) but I'm not sure how real the risk of burning out the PCI-E cords is.
since your using 4 connectors, none..
it is more if you only use 2 connectors, then its something to do with the quality of the cables..
with 4 connectors your inside of specs for the cables in regard to pcie specs
in your case, you have to look at your psu.. it might be pushing it to overclock your antminers...
