It looks like the s2 psu to me.
I can confirm this, I have this particular PSU, Enermax Revolution 87+ 1000W in my Ant S2 (batch 4), which I still own.

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

it was under powered for the s-2.

I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

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

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

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

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.

Cool, quiet and up to 1TH pod miner, on sale now!

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.

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.

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

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.

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...

 Molex?

 People still use Molex for hard drives?

LOL yeah that must be the reason. Just a little dust from delivery. Totally haven't been mining with their psu's for years Wink but seriously, I think that if they had them sitting around in a closet they would have done something else with them...maybe they just had a huge overstock too though.

The inside of mine was fairly clean by my standards - nothing caked up, but some dust collected in the ridges on wire bundles and stuff. The fan blades had a thin film of grime on 'em. It had definitely been used, but either in a fairly clean environment or they did a good job blowing it out before shipment.

I'm going to wait for Dogies review of the miner before I even consider looking at getting an S7 Lite. I like the form factor of it, and I would like to replace my S5's with these if they are actually decent miners.

Back in my day Bitcoin used to cost $69

Well, industrial compressed air systems are excellent for taking care of dust bunnies.
