Zich & 2GOOD:
I am using a 500W Lepa N500 ATX
http://www.lepatek.com/eng/product_content/1/1/1/#produkteUsing 1 DICE, I have the "regular" 6-pin PCI-E connected right now. It seems to be ok
But when I try to connect the 2nd DICE using 6+2 connector, they both seems to drop out/ not work.
I have an extra 650W Thermaltake that I could hook up to the 2nd DICE, but this seems excessive as the units only use less than 150W each!!
Maybe I am missing something to do with the Voltage or the Amp draw, but again, I would think that a 500W ATX could handle this.
Also, could it be my USB hub??? It is a powered hub, but works without the extra power?!?
Thanks again!!
Hey,
1. What is written on 500W ATX envelope 12v how many amps?
2. Is this psu single or multi rail. You are overloading it for sure
Probably PSU over-current protection kiks in or there is too big voltage drop in 12V output which dice is not able to handle
My advise for you is:
do not try anymore with this psu to power two Dice miners. You got lucky so far and there is no magic smoke yet
But if you continue to try the PSU will BLOW.
Send us picture of your psu stamp it says 12V Amps single or multy rail and so on
But once again do not push it anymore leave just one miner to mine
You can try to decrease chip voltage at the end. Not a good idea try with 680,670 and so on with just one miner at the beginning. Watch HW errors in cgminer. When they start to increase or if board does not want to start mining go one step backward. Doing this you will downclock the miner and decrease consumption - but HW errors will increase also. But as i said not good idea. If the PSU is 400W at 12V in reality you should not experience such problems
