Nope. ATX, CPU, and the 6-pins running off it look to be a custom job maybe 8 inches long. I'd like to use it as a PSU for my file server but I'll have to make the Molex jacks for it.

Molex?

People still use Molex for hard drives?

The PSU is the main selling point in my opinion. Correct me if I'm wrong anybody, but this PSU sells specifically for $180+. Plus I believe that this miner is the most silent they've had. Absolutely perfect for somebody getting into mining, or even big boys who just like a great deal of PSU with their miner.

Based on sidehack's statement, I am pretty sure these power supplies are used. I am definitely not a fan of using a power supply with an unknown history. I seriously doubt this miner is the most silent they have ever had especially when you compare it to the S1 and S3.

Hm...I am seeing that people have called it dusty which is a pretty good sign that it could be used. Which would be illegal for them since they do not say it is used...at least in my country. That obviously brings down the luster of the deal, getting half used hardware and thinking it is new.

Ahh...little dust don't mean it's used. Maybe this is just how things get delivered to bitmain...

This S7-LN version seems so cheap for it to include a power supply. The original S7 was nearly 2000 when it was first realeased right? and now a "lite" version is selling for 291 lol. I guess it just shows how big a mark up these things really have on them.

Does it have PSU all cabling? - CPU 4+4, Molex, SATA etc?

The cables on my PSU look pretty tidy, but yeah there's definitely dust inside.

On another note, my warranty is voided. I'm currently running one blade at 9.13V (610mV per node average) and 450MHz for 1TH at expected ~200W board-level. It's stable, 1 reported error in the last 15 minutes. I don't have an actual power measure, been doing other things.

I ended up yanking the PIC and talking to the DPOT directly, so I ran out a chart of 10mV (node-level) increments from 580 up to 770, the full range of the regulator. If I find time this weekend I might try and write a quick-and-dirty firmware for the PIC that sets the voltage at about 105% for 30 seconds or so and then takes it down to setpoint. I can run out a series of hex files based on the desired setpoint voltage, and then anyone with a screwdriver and PICKIT (I'm using a PICKit3, can be found readily enough for $30-50) can customize each board's voltage by accessing the ISP header after taking off the rear fan. I started discussing this process over in the Cheap S7 Repair thread, but maybe I should make a new one.

Looks like the default setpoint on this guy was 10V even rather than the ~10.3V of a full S7, which makes sense if it's designed to operate at 600MHz.

it is pretty good for the watts this unit will pull.

it was under powered for the s-2.

So there is no "real" problem with the psu but it looks they take them from the old an dusty stock?

Didn't you know we're talking about Bitmain??? It's their standard mode of operation. Or were you being sarcastic?

I really like the design of this unit. If BMT would release an S9 version, I would actually make a purchase.

I can confirm this, I have this particular PSU, Enermax Revolution 87+ 1000W in my Ant S2 (batch 4), which I still own.

It came out of the box fully assembled. Ethernet and C13 and you're off to the races.

So does it arrive like that with the PSU attached and plugged in and everything or do you have to assemble?

5-minute average 2716GH, temps 46 and 49, fans at 2880. I'm not a good reference for "how loud is this" because I have a high tolerance for fan noise; slept near a computer for the last 15 years, heated my living room with A1 Dragons and underclocked S4 the last two winters, and my desk is about 40 feet from 100KW of hosted machines. But I will say, I can't even hear it running sitting next to the S4+ (...whose PWM lines were clipped so the fans are rolling 4KRPM).

Sometime I'll put it in a quiet room next to an S3 and see how it compares. But now that I know it works I think I'm gonna do some hacking.

Awsome pics, mine arrives Friday!
