Sans Digital Power Supply Issues

Recommended Posts

revengineer

Having replaced two of these power supplies, I can tell you that they are a tight fit and the swap is not quite straightforward. I would hate to find out that a similar power supply is a fraction of an inch to large in one of the dimensions and turn the swap into an aggravating ordeal. I bit the bullet and ordered original replacements. The long term solution is to replace these enclosures with a Norco case to hold the drives.

now i have a tr4m+ i was using it as a NAS and torrent seedbox (by using a banana pi m1 as a controller, it has a SATA PM Mod)

and my PSU just failed. now im not going to spend $80 on hardware known to fail.

the specs of the tr4m+ say it has a 150 watt psu http://www.sansdigital.com/towerraid-/tr4mplus.html

 

could the following setup work instead

since i was mining for bitcoins i know of ATX switches like the following 2 products

1) ant switch (https://shop.bitmain.com/productDetail.htm?pid=00020140731043909819C9CL7qf4064A) obviously i wouldnt order from bitman as i dont need 500 of them)

2) or this one is a case mount jump start which is better for this project ​(http://r.ebay.com/iTzZ6d)

 

now here's where things get iffy for me

i gutted it already and it has 2 molex for input my issue here is how do i get enough power from the picopsu to go through those 2 molex, in order to power the entire system.

ideas i had to get this done

1) simply split the molen thats included out using a molex splitter

2) modify the jumpstart to have 2 molex connectors with enough power to supply the system (and one more for the fan) 

 
here's where im at
i dont know how much power went through the original molex connectors. i imagine a higher than normal current because of them supplying 4 HHDs and raid contorller
i also dont know if crimping multiple wires together to supply enough watts would be safe
 
now i haven't ordered the pico psu or adapter cables because i want to have an idea if this is could work or not.

i cant order my other post so im sorry for this double post

okay i ordered the switch off ebay (and because the seller can customise things i asked him to not assemble the switch)

i also ordered the pico psu 150 kit as well as another molex/sata connecter

and i also installed a new fan (ENERMAX UC-8EB)

 

its alive

 

this PSU is so small i am going to move my banana pi into the inside of the case once i get my case mount wires

i ordered them off aliexpress

2 regular USB 2.0 (for the USB ports, i dont really need but just in case.

1 usb-b to micro usb (for power)

1 cat 6 ethernet

1 SATA 3 cable (right angle (the directions of the connectors are: connector a: to the right; connector b: down)

all of them (except the sata cable) have case mount end on one end

 

and do my cable organisation and for my cable organisation i will be using heat shrink tubing and my soldering iron. (crimping well is not in my current skill set, and i dont have the needed crimp ends or needed pin pullers)

Pictures :)

here

for this its kinda hard taking pictures because the pico psu is so tiny (pico is a perfect name)

as you look do note i did a lot of modding to all the parts with my soldering iron.

i made a all the wires to length. so the entire setup was drop in

 

massive pictures in the spoiler

 

 

heres a pic i got off of geek.com that shows the picopsu next to a quarter

this is not the one i oun but it is the same size (a little thinner because mine is a 1 board setup

first a top view

255sxz4.jpg

#5 is my replaced fan this fan is silent.

#6 is the PSU. i wrapped it in electrical tape so it dosent short out.

#7 points to the atx jumpstart i bought off ebay

#8 was so i could show that i soldered the old molex connecters onto the pico psu's peripheral extension cable (i put one on each of the cables, and the psu came with 1 to start with)

#9 part of the ATX jumpstart, once i recieve new crimp ends i will size this down (the ones im using are too big fot the terminals on the switch)

#10 is a perfect spot for my banana pi

 

see heres the banaNAS controller with one drive installed

dr8nt0.jpg

 

heres the inside left view

atukns.jpg

#3 this was taken diring the install and this has been tightened down since

#4 heres the pico psu again

 

the inside right view

52f3lx.jpg

#2 is the original switch connected to the jumpstart

the rest of my notes arnt numbered

- next to the switch (i put it in upside down) is the old AC plug i needed this to hold the switch so i removed the contacts (i super heated them with a dremel (friction all the way) and pulled them with needle nose pliers)

- on the side of the old AC plug is the new plug with a ground lead soldered on

 

heres the back view

2l8krar.jpg

#11 is the old switch, because of the atx jumpstart it works as a power switch

#12 is the old AC plug with the contacts removed

i was originallly planning on using thus as the mounting spot for the new power jack but the jacs was too big

#13 is the new power jack

#14 is the old voltage selector, if i want to i could use a switch here as a power switch instead of the old rocker swicth that i have it set up to use now.

 

all picture were taken with a LG G4 (h811) running cyanogen mod

 

 

 

things i just noticed about the build

i should have connected the different parts (i.e. fan and psu cable) via crimping so it is more serviceable.) it is still fairly serviceable with the plugs it came with. but if i need to replace the fan then i will need to cut it up.

 

my future plans

move the banana pi inside, and have access to the ports with the following cables.

before i do this i am waiting the following parts i ordered off aliexpress

1) a micro usb to case mount usb b (for power)

2) 2x panel mount USB-a cables. (for those "oh s**t i need a keyboard" times)

3) panel mount ethernet (cat6) extension (for connectivity)

4) a specialised SATA-3 cable https://www.aliexpress.com/item/High-Quality-50cm-1-5-Serial-SATA-ATA-DATA-right-90-degree-to-down-angled-Lead/32233601538.html?spm=2114.13010608.0.0.QHs4l0

okay i received the bare minimum cables needed to move the pi inside. (ethernet, micro USB to USB-b, and SATA cable)
plus the SATA cable i ordered is no longer available on aliexpress (unless you want 100 of them)
a low-profile SATA cable would work as well

the sata cable i'm using looks like this
Syo3GTYHe.jpg

but heres the back of it now
B1NSMGTtHl.jpg
the USB-B supplies power to the pi

heres the inside with out a drive
https://jii.moe/BJXBGMaKSe.jpg
the cables were short but still were way too long, so i had to run them around the perimeter before i connect them

heres a top view with 1 drive halfway inserted
BJSGzaFHl.jpg

 
and heres a front view with all 3 of my drives inserted and the door open to see the pi and its lights (they dont show)
HkWSMMTFBe.jpg
in this photo you can see the drill holes on the top
 
my next mod will be adding 1 or 2 USB ports to the back (for the pi)
and sealing those holes and repainting the thing
epoxy putty will work well for the seal and im not sure about the paint, any suggestions (i will be using a spray paint)

The stock PSU sucks. I replaced all of them. Anyway, you have to drill a new hole to install the new one

Stock PSU

5V output cap = two 10V2200uF

12V output cap =  16V470uF +16V2200uF

 

You better add additional capacitors in it if If you are not willing to replace the PSU.
