I bought this power supply http://www.amazon.ca/gp/product/B00H33SFJU/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1 (EVGA 500W 80 PLUS Certified)
To power (1) Antminer S3 and possibly overclock it.
I've been hearing that the PCI-E connections are daisy chained and It can't handle the antminer.. could someone please confirm this?
I want to buy another Antminer s3... Should I
A) Buy another 500-600W PSU?
B) Return the EVGA 500W and buy a EVGA 1000W G2?
Please help me as I have no idea wtf is going on.
It seems that the PCIe power connectors of the EVGA 500W 80 Plus (see pictures in your linked site) are indeed daisy-chained or cascaded and presumably in a parallel configuration (2 power connectors on a single harness). It looks like a similar configuration with the Corsair CX500M (modular version) and I can affirm that the cable/wires got hot pretty quickly. However, why don't you test it first and see if the wires get hot. Perhaps, they're wired differently. Who knows?
Why didn't you just get the CX500 (non-modular version) instead. It has been battle-tested by so many users already, OC or not. In fact, the CX500 is 80 Plus "Bronze" rated is more efficient than the EVGA 500W with only a regular "80 Plus" rating.
