PSU Recommendation (UK)?

Mon Aug 20, 2012 9:41 pm

Hi, I've been playing with my Pi and finding that I can crash it fairly easily, so I did a bit of research and noted that I had a very poor PSU (400mA) and swapped it for the largest alternative I have in the house (a Kindle PSU @ 850mA). I can still crash it fairly easily merely running: rtorrent, rsync & compiling for good measure ;)

Now, according to Farnel the max it should be pulling is 1.2A, so obviously I should go for 1.2A+, but having read a few reviews on Amazon it's not clear what I should go for exactly, as I find reviews like http://www.amazon.co.uk/review/R10KUWVY ... lectronics for a 2A where two people specifically call it out as being unable to power the Pi (er, what: it's Samsung, so presumably reputable and accurately specified, and 2A should be way more than required?!)

So I'm asking for specific recommendations. I don't have a USB hub, I do have an external (powered) drive array, and I will likely plug in a USB sound card at some point. I'm probably what most people would term a "power user" as I will be compiling on there (probably Gentoo at some point when I can be bothered) and I will be pushing it, and probably playing with overclocking it too.

What specific PSU do you power users/overclockers recommend? First and foremost I want the thing stable!

Maplin mini USB power supply (product code N31FU), with mini USB 2.0 to micro USB adapter (product code N35JQ). Mains AC to 5V DC with up to 2.5A of current. Rock solid with Raspberry Pi.

No connection with Maplin -- just a satisfied customer.

Interesting, I'll ensure turbo mode is off. Thanks!

I've been very happy with this surge protected PSU made by Masterplug supplying 2x1A.
http://www.screwfix.com/p/masterplug-su ... lack/28341
Actually bought mine in Sainsbury's post-Christmas sale @ £4.99, so shop around.
Masterplug also do one with a single 1A USB output too, also available at Screwfix @ £6.99
