On low none of the wire/connections/solder joints are warm.
The PS is slightly warm (has a fan).

Ken, wow!
Great cable harness, great find on the low cost PCI-E connectors. What gage wire did you use going to the power supply?

Just wired one up, see pics.

Running on low now, ~32GHs

I'm going to let it run on low for awhile then kick it to high.
I'll post back after that.

I also installed a better fan (It moves a lot more air):

Thanks   ...   Ken

Edit:
The fan is noisy.
Couldn't hear the stock fan.
This one is very noticeable.

I see the list of PSUs by dogie now. no TT in there.

I think we already had this conversation with you, stex2009.  

Not all power supplies are equal.  Most power supplies are not made by the company branding and selling various model supplies.  They are built by other companies and as you might guess (or not), the quality of the components and the design can vary quite a bit.

Even the mighty Corsair falls into that group.

One of the few companies that actually designs and builds their own power supplies is Sea Sonic.  There are other companies that do as well but I'd say Sea Sonic is one of the more respected and recognized brand names at the consumer market level that does it.  There are a few companies that rebrand SeaSonic power supplies as a different brand.  XFX is one of those brands.  Some Corsair models are also rebranded Sea Sonic design platforms.  There are others.

I'm not familair with the specific Thermaltake model you linked to.  I know Thermaltake has used Channel Well as their OEM in the past but I can't say who made this supply and what quality components may be contained therein.

As DanZaph eludes to this might be an okay choice for an actual computer, but the power requirements that are being demanded from it by the Cube might be a bit too much for it to consistently handle.

The thing about the "ATX" PSUs is that they are purpose build to power a computer, a Cube is not a computer and has different power requirements; surprise, there are problems. They are being used because they are inexpensive, they are mass produced and they are cheap.

In the "day" when I was designing electronics I was used to purchasing single voltage units with current foldback for over current and crowbars to prevent over voltage. They can still be purchased, Lambda is still in business. But the price is much higher.

But today one can buy a 12v 30a supply from Amazon for $25 to $40 +shipping, just search for "12v 30A power supply". They do not come with PCI-E cables & connectors.
Example: http://www.amazon.com/dp/B00D7CWSCG/


Some one should try one.

When I use this PSU, my cube disconnects every few hours. Cube works fine on corsair 750W modular. Strange! why would that be? How come some PSU s work fine on cube and some others don't, even when they are very similar?

I agree with DanZaph, Apteryx, and dogie.

It could very well be a power issue.

Unfortunately the 'better' PSUs have overload protection that will be triggered by a cube. It sucks I know, my 1500W is crying in the corner because its relegated to powering gen 1 Avalons.

I would try adding a pair of large caps (10,000 uf) to the PCIe connectors as per the earlier parts of this thread,if it is voltage drop condition and it is only while the cube is starting then that may fix the problem, if, however the PSU cannot supply the continuous voltage necessary then that will make no difference.

Note that ATX PSUs are supposed to have separate "rails", each with over current protection. Thus a larger PSU has more "rails" (PCI-E) connectors but each has separate over current protection.

Adding another scenario:
a) The relay closes
b) The PSU over current protection drops the voltage.
c) he Cube sees the voltage drop and opens the relay.
d) The PSU no longer has an over current condition, restores the voltage.
e) The Cube sees sufficient voltage, closes the relay
This repeats and the relay buzzes.

Thanks! No, it's definitely not a power issue, I had it hooked up to a AX1200 and a AX1200i. I'll test that out this weekend.

The last sentence is interesting and perhaps key.

Why is the relay "buzzing"? A couple o possibilities:
1. The relay is defective. This would be very rare and there are many reported instances.
2. The control circuit is repeatedly activation and deactivating the relay.
I like number 2

Here is my scenario 1:
1a. The control circuit (probably involving a processor) senses the 12v supply is sufficient and energizes the relay.
1b. The extra load causes the supply voltage to drop and the control circuit  senses 12v supply is insufficient and de-energizes the relay.
1c. 1a and 1b repeat.

Here is my scenario 2:
2a) The relay closes
2b) The PSU over current protection drops the voltage.
2c) he Cube sees the voltage drop and opens the relay.
2d) The PSU no longer has an over current condition, restores the voltage.
2e) The Cube sees sufficient voltage, closes the relay
This repeats and the relay buzzes.

The supply voltage drop may be only momentary due to the current surge of powering up the device hashing. This could be caused by a PSU without enough capacity to handle the in-rush current. Or the PCI-E wires having to high a resistance (to long, wire gage to small). The "trick" of adding a substantially sized capacitor at the Cube's connector tends to support this theory.

What we need is someone with a storage-scope (or the modern equivalent) to examine two things: 1) The instantaneous voltage drop at the Cube on relay closing. 2) The instantaneous voltage drop in the PCI-E wire, this along with the resistance of the wire will provide the in-rush current. (I no longer have a storage scope.) Then we would have sone solid evidence to go on.


More info on PSU over current protection:
IEC 60950-1 that states that no single conductor can carry more than 240 W,
The ATX12V specification includes a requirement for an over current protection circuit in order to shut down any rail that pulls more than 240 W.

See: http://www.hardwaresecrets.com/article/Everything-You-Need-to-Know-About-Power-Supply-Protections/905/4 for more information.

Take soldering iron and put it to both pins same time till it melt. Same time you add some soldering wire and you will get little soldering bubble which will connect both pins. No need to add any other things (copper wire, tape....). It worked for me and now Cube works without interruptions.
But think about other possibility: maybe you have PS which can not provide enough current to your cube. Because of that voltage drops and relay K1 begin to 'buzz'.

hey thanks was hoping to help someone this units under warranty so im not messing with it but it is the 2nd one in a row that has buzzed out of the relay then popped fuses batting 1 outta 3 so far

Clock button toggles Low/High Clock.  Click Update/Restart after changing those values to commit.

Pools button toggles Pool A and Pool B.  Click Update/Restart after changing those values to commit as well  

I believe the server address can be either an IP address or a name address.


You may need to be running that address (stratum.d7.it) through an instance of the mining_proxy.exe.   Then point the Cube to computer running that proxy as you're doing with the first Cube (202).  I have no idea.  I'm not familiar with that pool.

You can run multiple instances of mining_proxy.exe on the same computer.

Looks correct.


This looks fine.  It's mining. A little on the slow side.  Clock is set to Low FYI.


Set Gateway to 192.168.1.1.  Shouldn't make much difference, but better to have it correct.

Pool is currently set to B, not A.  

I'm unfamiliar with that specific pool.  Do you have details or a link you can post to verify what you've entered is correct?


Have you tried just setting the second Cube (204) to similar settings to first Cube (202)?

Such as:

IP: 192.168.1.204
Mask: 255.255.255.0
Gateway: 192.168.1.1
WEB Port: 8000
Primary DNS: 192.168.1.1
Secondary DNS: 8.8.8.8
Pool Ports: 8332,8332
Pool Addresses: 192.168.1.111,192.168.1.111
Miners user:pass: Copy your user:pass field from Cube 1

I was playing with the settings, so that's how one clocked high and one low. I've tried everything. I've changed to the numeric ip you gave me for the stratum pool. I'll see how that works. I think they have their own stratum proxie there, so I'll give it a little while and see if it begins to hash. I never thought to test if the get work DNS was still active, that was a mistake. Hopefully I'll get it to do something with these new settings.

Thanks to BillTech for the great photos and relay research!

I notice a couple of interesting things from the closeup. Here is a portion of the image with annotating rectangles I have added:


The orange annotation shows a trace across the fuse, possible for testing and insufficient to handle the full load. I suspect that trying to run the cube without the fuse would vaporize this trace--with no harm.

The two blue annotations are probably used to indicate is one of the PCI_E connectors is not in place. We have noticed that there is different results with only one connected.

From the relay spec sheet note that the max in-rush current is 40A. That the knock-off-nib is in place is probably an error and probably should be removed.

does it require numeric ip as server pool host bottom image is named for server
also notice one clocks high and ones low

also that address doesn't resolve for me
•›› DNS: getwork.d7.it ...
•›› DNS-Error: getwork.d7.it

there stratum server resolves
•›› DNS: stratum.d7.lt ...
•›› DNS-Resolve: stratum.d7.lt is 84.240.24.209
