I've been looking into a Power Adapter to use with the TPi 2 and the Pico PSU addon through the KS. While I know I could easily and directly use a Mean Well GST90A12 and it would directly connect to the Pico PSU, I think my power requirements overall are a little higher. I plan on adding a UHD Blu Ray Drive and probably 2 SATA HDDs to the board, which at max power draw would be significantly ahead of the 80 watts of power provided by that Power Adapter. As such I have been looking into a Mean Well GST220A12 power adapter... but it has a 4 pin DIN that can't directly connect to the Pico PSU without an adapter of it's own. I looked into those, but the max amp draw on those is about 7.5 or 8 amps... negating the benefits of a larger power adapter. That brought me to two final choices. It looks like there is an adapter that I can use from Mini-Box.com (https://www.mini-box.com/4pin-miniDIN-miniFIT-JR-adapter) or I can just get a combined 192w power adapter and the converter as a bundle from Mini-Box.com (https://www.mini-box.com/12v-16A-AC-DC-Power-Adapter). I'd prefer to get the Mean Well supply... but I can't seem to find a way to get a 4 DIN to MiniFit-JR adapter anywhere else so I can use the full potential of the Pico PSU. Does anyone have suggestions on where / what I could get to be able to use the Mean Well without having to pay like $20 with shipping for this DIN -> MiniFit adapter?

Well I found a Pico PSU adapter for UK. Question is do I need to buy it? Or will appropriate Pico PSU adapters per country be provided in the add-ons sale? . https://www.mini-itx.com/~192W-AC-4PIN

An option for a UK power supply is on the TPi site now so I guess we will be able to get it as an add on but I also saw that adapter for Pico PSUs and thought it might not be worth importing an adapter from Turing Pi? https://turingpi.com/product/power-supply/

@booth5381 Thanks a little more digging and the prices of the external brick vary widely depending on how many amps and watts you need. 60Watt is only £22.80 https://www.mini-itx.com/~60w-ac

Looking at the Turing Pi site it looks like they are thinking of shipping the 160W Pico PSU and a 120W (12V * 10A) power brick. The nearest equivalent on that site would be 150W https://www.mini-itx.com/~150w-ac which is £57.60 but must be overkill for just the TPi and CM4s 🤔

Depends on if you're adding HDDs or optical drives to the mix

Are we going to have to hack the brick power supply, I don't see a barrel adapter on the pico PSU ?

It is there:

Is that the official one or just one you had?

This is the one that Turing Pi sells, the official one

I have a Pico PSU on hand. The plug is too small for the TP2 board. 😦

Which plug is too small for which connector?

The male plug on the Pico PSU is too small for the power socket on the TPi2.

Can you take a photo showing the issue? I can't quite imagine what do you mean

TPi2 vs Pico PSU

Oh, TPi2 uses 24-pin ATX connector, whereas your pico PSU is a 20-pin ATX plug

Thank you, I will give that a try.

I gave up on finding a matching power brick for picoPSU. Yesterday I bought a desktop charger but the cylindrical plug is a bit bigger than on picoPSU so I can't connect it. I ended up ordering a Gigabyte ATX PSU.

What's the desktop charger? Any specific model?

AKASA AK-PD120-03MEU 120W

Sadly it's a wrong one for 2 reasons

hahaha, I got that one when my board arrived. I can confirm it connects to the Pico PSU adapter

I used 20 pins pico in the past. Worked well for me.

Meanwell sells an adapter for the r7bf connector to mini barrel

DC PLUG-R7BF-P1M
1866-DCPLUG-R7BF-P1M-ND
BARREL ADAPTER KPJX-CM-4S TO 2.5

I got one from digikey. I'm using the meanwell 138w 12v psu with a pico.

If you received your shipments, check your Picos. Some of us received them with loose capacitors:

I assume the 12V 6A 72W version would work too?

Most likely - yes. You need to check on your own how much power do you need. 4 CM4 modules loaded and the TPi2 board need about 20W. Add SSDs/HDDs and other peripherals and you'll know. I'm currently using 60W with Orin NX, 3 CM4s and 5x 2.5" HDDs 🙂

Is there any harm in going over (in terms of watts)? I'm going to have 4 CM4 modules and an SSD (which shouldn't put me anywhere close to 72W).

There's no harm at all. It's totally fine to use even much bigger power supply. The only downside is worker efficiency at low loads

Thanks for the replies. I appreciate it.

Hi, any chance for a model number or datasheet on the PicoPSU please? I cant seem to find one anywhere

@uncle_phuzzy someone (not Turing Pi team) long time ago posted this, in January... i think this is the same model pico-psu, https://www.amazon.com/Mini-Box-picoPSU-160-XT-Power-Mini-ITX-Supply/dp/B005TWE6B8/ and also the oem page, https://www.mini-box.com/picoPSU-160-XT

Thanks, yea I have seen those. I am looking at the one linked above as the official model, the links point at the Minibox mode which is not the same as what was shipped

You can use any Pico PSU as long as it has enough power. The one that TPi sells is 160W, but 4 CM4 modules and TPi2 board need about 20W. You can calculate additional power is you add NVMe drives, SATA drives or other modules. On top of this, you need 12V a power brick that matches the output power (with 5.2/2.5 barrel plug)

oh, sorry, just noticed the vendor does not have the one I bought anymore. Better to remove the link from here @DhanOS

The Amazon link was very helpful. You're not talking about removing that one, right?

It looks like the 144W option is not there in this link anymore

But the 72W is still ok for most of the people

and you already have a picoPSU in hand right?

I ended up going with https://a.co/d/6vYAnbL The barrel plug fits out of the box. It's not quite the 144 watt adapter som are looking for, but it should work for my loads.
