My gridseed bitcoin miner has a 12v fan and needs  12v 5a to run and i got a new 12v adapter becuse the old one was getting way to hot to the point it was melting the sticker a bit so I got a new 12v adapter with same same output as the old one and the miner is not having any of it. The fan will run but the miner will not mine and will keep giving me this 2017-04-22 18:45:28] System reseting
 [2017-04-22 18:45:29] HW error, do hardware reset. I am not going to use the old adapter because it is a fire risk and im not buying a new adapter because the one i just got was $71 nzd
can someone tell me what to do to fix this

nzd = New Zealand dollars correct

So you are in New Zealand  correct?


 You purchased  a second adapter without asking us.

So what   are the specs on the  adapter you purchased?   are they 12 volts and  7 amps    if not you purchased one that is too weak.

I had 18 of the blades and 35 of the round discs models back in the day.  I know this gear.

Like it or not you will need a better adapter.  or worse yet the gear is damaged  and uses too much

power.


this one would do it  it is a 10 amp.

but you need an atx psu

its the same as the old one and the old one works with it 12v 5a

5 Amp cubes were marginal on the old Gridseed blades, especially if you were pushing them past about 2.5 MHash/s - ESPECIALLY on the blade with the fan connected to it.

 It sounds like you might have gotten a cube that doesn't quite meet specs though - but I WOULD strongly recommend going with at least a 7 amp cube to leave yourself some leeway.
 There's a REASON your old 5A cube was running VERY hot.

logical solution, buy cheap PC PSU throw cheap ass shitty power brick hard at the nearest wall. go on ebay and buy a couple DIY DC barrel jacks. cut molex off new PC PSU and wire yellow to positive (the inside part of the DC jack and black to negative outside of the DC jack, either get a PSU tripper so it turns without a computer or get one of the switches. done youve now got a PC PSU powering you miners and its go a nice big fan to keep the PSU cool

the DC power bricks are good ideas but there very inefective and very very bad ideas for drawing lots of current all the time, there enclosed and just get hotter and hotter
