Antminer S1 power supply

[zildogh]

hi

just got my antminer s1 and corsair 500m up and running.  the 500m comes with the 2 pci e plugs on 1 cable, i saw this mentioned before that its not a good idea to run the 2 off 1 cable so im just running 1 blade untill i find a solution. which im hoping someone can help me with pls?

it has another 2 port that are 6 pin on the psu, are these pci-e ports? what can i do to supply the other blade? what happens if i run 2 blades from the 1 cable? im not to savvy when it comes to psus etc...

thanks for any help guys

Just to update, I tried the 2 pci e connections on the strand, and noticed the wires started to heat up quite quickly. So I didn't leave them in for too long. So what I've done is put 1  6 pin pci e in 1 blade, and for the other I've took the 12v from the 8/4 CPU plug using a 6 pin female pci e connector and then spliced the ends to fit the 2nd blade terminals at ground and +.  I was getting 11.97vdc at both blades. Does this sound ok? I'm using a corsair 500 m

It's up and running ok. Looki gs good getting 180 gh+. Does anyone know what reject rates we should be getting at the pools?

Just a note if anyone tries this. Be careful not to get reverse polarity as the wire colors reverse when u connect them due to the pin outs.

I have 2 RM750's powering 3 overclocked S1's.

Total wattage +-1100W from the wall and 4.8A

Hi,

I'm curious how you did this setup?  I want to do something similar.  I know you have to apply primary power to the control board side of each of the ants.

I plugged each PSU to an ant with double PCIE cables (which you use for your graphics cards).
Then I had an adapter that went from 2x molex to 1x 6pin and use one on each PSU.
In total of 1100W, each PSU is pulling 550-600W.

just blew my corsair 500 =\ I thought I was passed this. But Im also running 1 blade and 2 gridseeds with it... that was probably my downfall. upgrading to a 750

Im running mine with 550W PSU and its running fine.

I used  PSU a server PSU, it works very stable!
In fact, almost any PSU can make the ants work stable.

Here's my take on this.
After burning up one of my "decent" power supplies and stressing my "good" power supply, I looked for alternatives.
A regular PC power supply is also working to generate 5VDC and 3.3VDC.  We don't need these for an S1 with a pair of blades installed.
Since the Antminer S1 is only 12VDC input, I looked for a stable 12VDC power supply.
I picked up two Supernight LED Driver, 12VDC 30A power supplies, dialled them in to as close to 12VDC as possible (they are adjustable, one is at 12.00, the other is 12.02).
These have run cool and stable and I have my S1 OC to 393.75.
This is just on the bench, with a secondary 120mm fan drawing air out, and I'm peaking at 46* for temps.
The plan is to put a proper housing on them for cooling.
I've also put heat sinks on all of the ASIC chips and started putting them on the others but ran out (ordered more 6mm and 14mm heat sinks for the regulators and remaining small chips).
Heat sinks are like $25 per 100 count, so not so bad.  I've used them on my U1s as well.  I'll be resistor modding those soon and mounting them to a dedicated heat sink with cooling fan.
For less than $30 each on eBay, this may be an option for some of us.
The pair cost me a little under $56.

Can the dell 750W psu run two antminer s1s well?

I powered two 400MHz S1 with one for six months without issue (except for one overheat in July when the PSU fan was turned too low).
