Title: ATX PSU for Gridseed Post by: AJinNYC on December 07, 2014, 01:24:41 AM This is a bit of a cross-over post since it's for the Gridseed miner. But, I just bought a Gridseed dual miner and GAW Srypt miner from eBay along with a Corsair RM1000 from amazon. The miners are coming with Molex to 2.1 barrel adapters. I know the Corsair has Molex connectors, but what are those connectors pulling from? +12v, +5v, +3.3v, -12v? Combined the miner should be pulling about 100 watts/hour (running the Gridseed in dual-mode) but if the Molex connectors connect to something other than the +12v, +5v, or the +3.3v then, if I'm not mistaken, I shouldn't be using them.
I'm suspecting I'm okay using them as the +3.3 and +5 max at 150watts combined and the +12v is 1000 watts, but I wanted to double check with somebody that has more knowledge on this than me.

Miner usually use 12 V, so just make sure that the molex to 2.1 barrel adapter connect to 12V side which is Yellow color(+12V) & Black color(ground) Title: Re: ATX PSU for Gridseed Post by: Unacceptable on December 08, 2014, 12:11:20 AM Your talking about the 4 pin molex for HDD's & CD/DVD readers right ???
http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral Don't draw more than 100 watts per CABLE,not per connector. I used this to run 5 little gridseeds,each GS is about 10 watts OC'ed,so each PCIE could run 20 of them: https://i.imgur.com/0l5KmZP.jpg You can get the cable from Cablez (https://bitcointalk.org/index.php?action=profile;u=54059) ;) I made my own 4 pin molex cables to run them too.I bought these: http://www.amazon.com/gp/product/B0058RLD9C/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 & these (take your pick): http://www.frozencpu.com/cat/l3/g51/c387/s999/list/p1/Connectors-4_Pin_Connectors-Molex_-_Male-Page1.html Be sure to add the pins to your order,they DON'T come with them automatically ::) I got my wire from old PSU's & ran 5 per cable,can't find my pics of that cable :( Zich is correct...YELLOW is 12 volt +...RED is 5 volt +...each has it's own black or negative (keep them paired). When making your own cables,you do not have to add the red 5 volt & it's black cable,just the yellow & it's black cable ;) BTW,I have cables left over if you want buy them ;D Title: Re: ATX PSU for Gridseed Post by: AJinNYC on December 12, 2014, 08:44:47 PM Well this is what came with the miners. They're certainly a bit of a patch job (spliced and wrapped with electrical tape) but Yellow and Black; so I'm assuming all good.
