What is the power limit for one 8 pin EPS connector?

[RenaKry]

With X299 and X399, many motherboards are sporting dual EPS connectors. For the sake of futureproofing, I want a power supply that has enough juice to run either a Core i9 or Threadripper overclocked under water cooling. I know that PCIe cards draw 75w from the motherboard and an additional 75w per 6 pin connector and 150w per 8 pin connector, so ideally a GTX 1080 will never draw more than 225w by spec at when overclocked since it has one 8 pin connector. My 5820K has been able to draw about 230w under full load overclocked to 4.4 GHz at 1.35v when running Folding@home and the motherboard has one 8 pin EPS connector. 

 

The question is what is the max amount of power the CPU is allowed to draw by specification if the motherboard has one 8 pin EPS connector? What about one 4 pin and two 8 pin EPS connectors?

it would be the same as an 8pin pci-e connector seeing as they both use the same wire gauge/pins/studs. the only difference is their keying and ground/12v placement

PCIe and EPS use the same connector, unfortunately.

Main Boards with an 8 pin EPS12V CPU power receptacle can supply 235 continuous watts

The 4 pin supplies 155 watts, and the 8 pin supplies 235 continuous watts. For most of the newer processors, even during extreme overclocking, ether connector would work fine. If you want to, you can even connect both the 8 pin and 4 pin CPU connections, all it will do is farther increase the wattage that is available to the CPU (315 watts).

I think 120

 

doing a google search confirms this

 

 

oh wait i'm thinking of PCIE, brb

 

288W

Like whoever made the old California Raisins commercials.
