Fairly good price for the 2GB model. 926 left in stock at the time of posting, free deivery.

SPECS:

Raspberry Pi 4 Model B is the latest product in the popular Raspberry Pi range of computers. It offers ground-breaking increases in processor speed, multimedia performance, memory, and connectivity compared to the prior-generation Raspberry Pi 3 Model B+, while retaining backwards compatibility and similar power consumption. For the end user, Raspberry Pi 4 Model B provides desktop performance comparable to entry-level x86 PC systems. This product's key features include a high-performance 64-bit quad-core processor, dual-display support at resolutions up to 4K via a pair of micro-HDMI ports, hardware video decode at up to 4Kp60, 2GB of RAM, dual-band 2.4/5.0GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, and PoE capability (via a separate PoE HAT add-on). The dual-band wireless LAN and Bluetooth have modular compliance certification, allowing the board to be designed into end products with significantly reduced compliance testing, improving both cost and time to market.
  • Broadcom BCM2711, quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz

Bit of a minor conspiracy theory there. The reality is that poor USB supplies aren't as much of a factor for charging a device, when it can just charge slower, as opposed to powering a device like the Pi that absolutely requires sufficient power.

I've used a decent non-official power supply without problems on all my Pi's, but the key word is decent. And unfortunately too many people don't, so the sensible thing is to point them to the official PSU.

Haven't looked for a while but normally sellers on eBay selling the 4gb version for this. But good price glad they dropped the price since the 1gb wasn't in demand.

I've been looking for the 4GB for myself, cannot find it anywhere in ebay for less than £40. It seems sellers increased the prices the last few weeks as it was around £35 in Feb. Either way, I've not seen the 2GB one cheaper than this.

Fair emough would of been around then I was looking I'm sure price will fluctuate down again but this is a good price on the midrange and for what most people will use them for ideal.
I got this early March from CPC. Make sure you buy the official power supply with it guys

Thanks OP, I was considering Banana pi M2 zero to run linux and google colab +VNC, but this will be perfect!
I got my 4GB for £35 from ebay and it seems to pop up every so often as a deal so if you're not desperate I'd wait.

I use this PSU and it's been really good, but I paid $2.99 and it's $5.99 (+ $1.25 postage).

True. I did too. Personally I prefer a psu with a switch on it though. Great for my 3d printer.

Buying cheap PSUs for a Raspberry Pi (especially recent models) is never a good idea. Power issues are one of the main reasons people have problems, the forums have a long thread on this for that exact reason. Get the official PSU, and if you really want a switch, places like The Pi Hut do a short USB C one you can add to it
Can android TV be installed on these? With app store support?

No. To all these questions. One has nothing to do with the other. Can be used as a server alongside the Mac.

It's not to do with that. It's years and years of forum posts from people wondering why things aren't working. A huge % of these issues are down to cheap nasty power supplies. It's just not worth it considering the official recommended PSU is £8. If it was expensive I'd understand why people deviate, but it's not.

Because not everyone always needs a new PSU every time they buy a new Pi. And some people know PSUs well and know what to look for or buy, but this isn't the case for most. Also, some projects (like audio) will use a different PSU altogether. But every store and Raspberry Pi themselves will recommend the official PSU, plus stater kits DO bundle them - so it's really not hard to get the message. And the reason there's an official PSU (there always has been BTW, it's not a new thing), is to avoid 10 million BS forum posts from people saying "my phone charger from 2001 isn't working"

Good point.

What causes non-official power supplier with problems? Are there any brands which are better than others? Just incase ppl have them lying around.

Agreed. I've had many Pi's over the years and had issues with poor PSUs. I wouldn't buy anything other than the official or something from a decent manufacturer with confirmed reviews saying it was OK. Most of those are around the same price as the official one though. So to save a few quid and for a switch it's not worth it.
taras20/04/2020 08:17

Not bad at all on the 4GB version - I wouldn't consider the 2GB for a desktop replacement. Manjaro 64bit flies on the 4GB. If you have a monitor and keyboard lying around then it makes for a cheap desktop replacement for light duties.
Would this be any good purely as a Plex server?

I run one as a Plex server and it works well, can do 4k too. Dietpi + Plex works well IMO

I did have a Pi3 and that could do 1080 but struggled with 4k, upgraded to one of these and it is great

Hmm not sure. I'll assume quality parts with good headroom. I did the cheapo PSU thing for a while, all was well until one started melting the outer plastic. Could have been the end of my home - never again! Avoid anything no name, but even then it's hard to know 'names' if you're not in the power supply industry, hence most stick with official option. Stontronics used to make the original Pi PSUs I think, so they're probably decent.

Thanks, I'm well aware of that having had basically every Pi since release and still having 6, none of which use the official psu and all work fine. This one works great though, is 5v 3a and they've sold well over 1000.
Thanks OP - ordered and +1 heat added

Also - should be able to get 9.6% quidco for farnell off the price too - tracked for me

The issue is you need a 3A PSU for the Pi 4, and there are very few (if any) mobile phones or tablets that actually come with a PSU which can supply a current like that. With previous RPi revisions you'd have probably got away with something like an iPad charger as it's rated at 2.5A (sufficient for RPi 3+ and older) and is of reasonable quality (i'm sure someone will LOL at that, but it's certainly not cheap eBay junk) but a lot of PSUs bundled with phones are for charging and thus a steady voltage/current isn't as much of a concern as it is when you are using it to operate a device. Computers have always depended on good quality PSUs - take a look at some pre-built PC deals on here; the first thing people will be looking at is the PSU and use it as a litmus test for the quality of the overall build.

So if you have a reasonable quality 3A PSU then no, you don't need the official PSU. When I was looking when I bought my Pi 4 it transpired that a good quality 3A PSU was as much, if not more, than the official one anyway.

So the reason for suggesting people to get the official one is for practical and not nefarious reasons, i.e. people can recommend them in full confidence they will work and they are reasonably priced.

As for not bundling it with one: a lot of buyers will not need the PSU. Maybe because they already have one (official or not) or they plan to run it off a battery, or they will power it via other methods (POE, using the GPIO pins, etc.)

I stuck a POE hat on my one which I hope will be a decent option for power.
I've never used an official raspberry pi power adapter. I've been using these since the original and yes, people have power issues but normally that's people using power supply from old phone adapters with completely different wattage and voltage.

If this was a real issue this would be like Apple selling their own products... But it isn't.

They did have issues with this model though. This is now fixed.
One other reason for an official Pi power supply is that the Pi is tested for certification against numerous industry standards, and the power supply will of course be a part of this. It's even being used for ventilators: bbc.co.uk/new…286

Obviously for hobbyist work that's less essential, and you might get away with slightly lower than 3A for a Pi 4 without any demanding USB devices (as long as it's otherwise decent), but it's understandable why the official PSU is presented as the standard.
