More Power!

Postby J4K » 18 Apr 2018, 22:59

Hello peeps,

I'm looking to upgrade the wall wart for my rpi3b, currently has IQAudio dac+, and official rpi touch screen.

I'm going to lose the screen and run headless, as it it rarely used.

I've found this: http://www.swagmanlab.com/Product_All?product_id=631&brd=1

The Specs are similar with 3A Instead of the required 2.5A.

Will half an amp be a problem?

And is anyone using/used one?

RPI feeding Roksan Kandy K2 Integrated/ TR5 S2 / With Mark Grant cables in case anyone is interested.

Thanx for reading

HI J4K,

This power supply is suitable for the Pi's used with RuneAudio. A 3Amp supply is recommended for the Pi 3B and Pi 3B+ models.
It is a linear power supply, this is a higher quality product than a switching power supply and should provide cleaner power. A switching supply would save you around $100, compared with this one. Not everyone is convinced that a linear power supply provides enough benefits to warrant the significant extra costs. See here for some tests using a simpler switching supply: http://archimago.blogspot.nl/2016/10/me ... berry.html
