Title: Power Cords Post by: chume on January 10, 2012, 01:38:33 AM I have just replaced the power cord on my mining system. It has 2 5770's, a 5850, and a 5670. I am using a 760 watt psu. This is the old power cord.

What did i do wrong? Title: Re: Power Cords Post by: KingLinkTiger on January 10, 2012, 01:50:23 AM Without knowing the complete circumstances of how it broke I would speculate that it could be a faulty cord. I can only think of plastic/rubber getting brittle when exposed to cold, is your miner located in some place that is extremely cool? (ie outside or basement)
Title: Re: Power Cords Post by: chromeguy on January 10, 2012, 01:57:44 AM watts divided by volts gives amps
thus your cord load would be (maximum) 760 / 120 if american = 6.333amps 760 / 240 if other = 3.166amps cord not overload or heat up, cord (should) handle 10amps easily another thought is - that plastic goes brittle if exposed to UV (sunlight, hydroponic rig, etc) or other BPA leeching substances like harsh chems (bleach etc) also, use imgur - better, faster, no limits, no crappy wrapper pages. also has fb signup for ease of use Title: Re: Power Cords Post by: Kluge on January 10, 2012, 02:15:18 AM another thought is - that plastic goes brittle if exposed to UV (sunlight, hydroponic rig, etc) or other BPA leeching substances like harsh chems (bleach etc) only thing I can think of. The cord appears to be in fairly standard household conditions. I'd assume it's been in direct sunlight for a long time.Title: Re: Power Cords Post by: the joint on January 10, 2012, 02:36:26 AM Power chord = Root + 5th
