New Power Supply for the MiSTer Digital Edition

[outatime]

Hello,

i received my Mister today and it includes a Standard 5V 2A Power Supply by L.T.E. with a US plug.

Now I want to replace this supply for a one piece EU plug Version without using a travel adapter.

My mister has the additional USB board and I want to connect a WiFi usb dongle and 2 8bitdo dongles for my wireless controllers. Also the Noctua fan is build in. Now I’m insecure how much more Ampere I can choose.

The official GitHub statement says:

„The DE10 boards needs a 5V power supply with at least 2A. One such PSU is included with the DE10-Nano board.“

There is no limit listed but as most Rasperries have 3 or 4 Ampere.

Is there any problem with 4A / 20 Watts in the long term?

More ampere is no issue, it just referes to how much the power supply can provide, while your device only takes what it needs. I use a Mean Well GST60A05-P1J power supply which has 5V/6A without issue. The correct voltage of 5V is the critical value and that you use a PSU with at least 2A. Less does not provide enough power.

Ok, thank you. So I need at least 2 A and go up high is I want as long as the device has the 5V? Think I will take this Meanwell, too.

But your device needs and additional cable for the right domestic plug, right? This is only the power supply.

[Threepwood]

That is all correct, yes, including that you need to buy the cable separate.

Thank you, what I ordered now is a MeanWell 5V 6A Slim Wall Adaptor in one piece, fantastic build.

I got the GST60A05 and it works fine. According to the specification the GST60A05 is a bit more efficient than GST25B05, but ripple is up to 120mVpp vs 80mVpp - I suppose that's at full load, so I'm not sure if for our usage the GST60A05 effectively has more ripple. Anyway, it works perfect for me, and I prefer this desktop format.
