Hi there

I have a setup with Raspberry Pi3+, mounted with the ApplePi DAC (no
longer available).

My problem is that I have a yellow lightning-bolt, and during boot
process I get a 'under-voltage' error.

Wifi and Bluetooth + HDMI is disabled to reduce the power requirement,
and I'm using standard settings (not overclocking, almost rather the
opposite).

I know the ApplePi requires quite some juice. Therefore it is default
delivered with a powerful 5.25 Volt and 3 Ampere PSU. Like this one:

I think my problem is the cable. It cannot be replaced on this
particular PSU. Does anyone know of another one which can deliver about
16 Watt?

Ideally one where I can decide what USB cable I use (replaceable), and
I'd like one with 20 AWG wire inside for the power-line. Like this one:

https://www.amazon.de/-/en/Original-G4-G3-G2-High-20-AWG-Charger-Retail/dp/B01KI4LYFM/

... Unfortunately this reseller doesn't ship to Norway or Denmark.

P.S. I did a thermal image on the DAC-board and the temperature is 43
deg Celsius ... the developer and I agree, that's low, and there's
nothing on the board that is near dead and causing unusual power draw.

I really think it's that darn cable, or maybe just the connector - maybe
some contact cleaner could solve the problem. Anyone else have such
problems, and how did you solve it?

Any comment is highly appreciated. Thanks.

Best regards,
Claus
