AntMiner APW3-12-1600 PSU Series by BITMAIN

AntMiner APW3-12-1600 PSU Series Bitmain is excited to share that the AntMiner APW3-12-1600 PSU Series is officially available! This AC-DC PSU is made with miners in mind, offering high efficiency and solid performance packed into a compact design. It also comes with protections against short circuits, overloads, overheating, low voltage, and more. 1. The PSU has a bunch of features that make it great for crypto mining, like: 1) The airflow goes from the AC input to the DC output, which matches the setup of most miners. This is super helpful for those running big mining setups where managing heat is key. 2) The PCB is coated to avoid damage from high voltage sparks around the MOS pins or from solder joints if dust gets in the PSU. 3) The APW3-12-1600 can run smoothly in environments up to 50°C. If it gets hotter than that, you should underclock it (check the Max Load vs. Ambient Temperature Graph in the user manual for more info). Given that mining can get pretty toasty, all internal parts are rated for 105°C, so this PSU is built to last way longer than regular ones under similar heat conditions. 4) The APW3-12-1600-B2 features a PCI-E connector, making it compatible with most ATX PSUs and many bitcoin mining rigs. One APW3-12-1600 can easily power two AntMiner S5s at the same time.

Very nice and official PSU Link = https://bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694

I don't understand why other PSU manifacturer never offered a mining PSU.

Good job, Bitmain! Is it an allusion to your new not yet announced 1U miner?

No, its the same PSU in the S4+, which is 3U.

PCI-E cables 16AWG or 18AWG? Noise? and at what fan speed? Fan speed variable or fixed? Who is the original manufacturer?

Good question, I'll try and find out. The spade connector version used 10AWG. I couldn't notice the fan noise even during a 45C ambient test, unsure on the RPM but its not quick. This unit can 100% load @ 50C and 80% load at 60C so I would have thought it was variable to hit those higher numbers. I doubt they'll say who the OEM is. It was always the plan to sell the PSUs.

sorry bitmain but at that price used server class delta psus is better option

and please show me a delta server with a breakout board for 12 pcie connectors they said 12 pairs in the copy but I think they mean 12 connectors .that does 1600 watts at 92% efficency with a 1 year warranty  . cost 155 usd. My issues are not with price . Quality control based on the post above yours . and does it do 92% at 1500-1600 watts? does it do 93.8% at 1200 watts? last question is are the wires 16 gauge?  I could see someone running 2 s-5's and this psu have issues if the wires are 18 gauge.

Its 18AWG.

not good but thanks for an honest answer. if I buy this with 2 s-5's  I will be pushing the wires at freq 375 and higher. btw 1 of these psu's and 2 s-5s is 911 usd with shipping 1 s4+ is 1071 usd with shipping

In that case it would seem appropriate to provide a maximum amperage per connection in the specs and make it clear, it could be dangerous for your customers if not..

18AWG? Gross. Though 1600W at 12 cables is only about 4A per wire... That'd be good enough for most things. I'd like to see one of these hooked up to some Neptune cubes and watch the entire setup burst into flames though. Also, Phil, how does my DPS-2000BB breakout board and PSU stack up to your criteria? The efficiency might not be quite as good, but the board holds 12 cables natively (I've run 16 without issue, pushing two Prismas per PSU) and a kit costs less than $155. We don't 1-year the PSU (90 days typical for used equipment) but lifetime on the board and cables. By the numbers this is a nice-lookin' PSU. I hope Dogie's right about the fan not sounding terrible, because every 1U fan I've listened to (for example DPS800, DPS1200 and all SP rackables) are super annoying. It'd be nice to have user-defined cabling too.

actually you don't need breakout boards for them i solder wires directly to psu pins it only requres time and 100W soldering iron

Holy shit.. Be careful with these things guys.. Look at those pictures above.. Looks like bitmain is selling house burners if you ask me. I'd advise everyone to be careful as hell if you are buying these and make sure you inspect them inside and out. I'm disgusted that shit like that even made it through their QA testing... Step up your game bitmain before you kill someone.

So, does this mean that you will only provide support for people using Bitmain(Tm) power supplies for future miners? Or is this just me being paranoid?

Why would it be? S6 @ 375 is no more than 600W pre PSU = 150W per cable strand = perfectly fine on 18AWG. On tubes we were doing 250-300W per cable strand on 18AWG which was the sensible limit. Fixed That's what I expected to, thought I'd have to stress test it during the first day then turn it off but nope, I actually can't hear the fan in my setup. While I can't tachometer it (blades are too small for a marker dot), it does look pretty low RPM. Maybe we can have different cabled versions in the future.

Extremely paranoid As long as you're not using a 300x 12V rail PSU made by SUPERHIBIGPOWERWOWLED corporation, I'll help out where I can. It has short circuit protection, as it worked in this case. I'm not sure what the point of that drilled hole was, but it will get fixed.

No, I stand by what I said. It'd be fun to see someone hook one of these up to a Neptune thinking "oh, 1600W is plenty" and see the jackets on the 18AWG wires wilt off within a few seconds before the whole thing starts burning. The PSU itself might survive but not the cabling. It's a terrible idea (I can't in good conscience ever recommend anyone run Neptunes) but if someone does it I'd like to see video. Be much less fun if it had 16AWG wires. 150W on 18AWG is probaby okay. 8-pin PCIe for GPUs are probably mostly 18AWG and those are rated for 150W by the standard, which means they're probably capable of more, and 8-pin PCIe only has three power leads.
