You guys have been a huge help. Thanks!
I just talked to my electrician. We are doing (3) outlets each connected to its own 240v/30 amp breaker (I have the space). There is a surge protector being installed on the whole panel (internally). I will go with one of the PDU's shown above that are rated for 30 amp but pushes less. The outlets are right by my panel which works perfect. My plan is to only plug 3 miners in each PDU to start as I work my way up to 9 miners (3 PDU's).
Has anyone seen a difference with using the Bitmain power supply compared to the EVGA power supply? The Bitmain's is much cheaper and didn't know if the EVGA is really even necessary with my electrical setup now. I know most people use the EVGA because they are using 120v. Thoughts?
Once again thanks for all of your help thus far.
They're better, more expensive PSU's. If you want cost effective, go ahead. Personally i like the cleanest powers for my miners. But with how much money you can save, then maybe servers PSU's are the way to go.
However getting PSU packages from the forum is a better price. The Bitmain PSU is not really that much of an interesting buy.
EVGA to get the PCIE cables and power needed your up to the EVGA 1600, it runs around 400 or so. So extremely high. You can get server PSU's much cheaper.
There are some "kits" that can power multiple S7's if you go big enough. And there is of course the bitmain server psu. I have not had any issues with them they seem to work good.
With getting 240 I would compare prices on kit's and bitmains PSU. Either way you go it will beat the EVGA by far on cost.
You can use 1300W fine, and thats 175USD but yeah its still expensive to power a single S7, especially with the nice kits using J4bberw0ck's breakout boards.
The 1300 does not come with 10 PCIe cables. Also look at B8/B9 efficiency. I would not guarantee a 1300 doing it on current batches.
Even if it did run it would be pushing the 1300W pretty much at max unless you under-clock it.
The EVGA, unlike most PSU out there, are underated for efficiency, at least, their peak limit is much higher than their rated #.
They can actually run their "100% load" no problem. Their components does not degrade easily and as such you'll find yourself possibly not needing to ever RMA it. My EVGA 1000 with 3 years used get the same reading as the brand new one. So running them at 98% load is just fine, it can handle spikes easily from there, it even handle 104% no problem. Though i'm not sure whats the true limit is.
They really can do their rated load, DC, continuously with no problem. The only downside is efficiency loss.
Now i don't know if this numbers hold across all that S7 design, but so far
i get 1280W DC with my B8. I run the fans at 3360 RPM.
And yeah, you might need to get an extra cable, or maybe not, the way i set it up is;
3 double, 1 per blade, 1 single 1 per blade. Then a periff for the controller. I did not need to come up with any extra cables myself.
I don't know where i got these PCI-e converter, but i have so many of them. And since these baby are modular, i simply used a 3rd double from another EVGA.
Worse case scenario, if you somehow has absolutely nothing on hand (i have spare of everything, because being ready for anything is my motto). Grab some extra cables and perhaps y splitter while you're at it. Start by checking Finksy and Klondite's stuff.
In this case, you could get 2 4$ y splitter. If you absolutely have nothing on hand for some reason.
