Re: Is 2.5A enough for the Pi 4?

That said, it should still be more than sufficient. Testing shows that 12.5W was not enough to power the HDMI signal on certain monitors. During testing I found that swapping a working system to the lower power psu results in HDMI signal loss, whereas the official 15.3 W power supply works without ...

Re: Is 2.5A enough for the Pi 4?

Who was this vendor ? Other purchasers would be advised to steer clear of those who engage in such practices. I purchased this from buypi.ca Though I must say that I am quite disappointed by the quality of care as they vendor chose to ignore my requests for a refund on the power supply to make thin...

Re: Is 2.5A enough for the Pi 4?

I wanted to update my results for anyone facing a similar problem in the future. The first thing to notes is that I was contending with two separate issues; The first issue was due to a power supply insufficiency, which was causing HDMI signal failure. The second issue was due to a faulty or micro-S...

I just wanted to update this thread with my results for anyone facing a similar problem in the future. The first thing to notes is that I was contending with two issues; The first being that my power supply was insufficient and that it was causing my HDMI signal to drop.

Are you sure the sd card is genuine? Have you got another sd card you can try?
That's an excellent suggestion, I have other cards - will test asap

Re: Is 2.5A enough for the Pi 4?

I just wanted to add that I received an official response from raspberrypi.org on matters; Hi Ignore the previous email, the new Raspberry Pi 4 needs more juice than previous models - You'll need an official 5.1V 3A power supply (or equivalent). Kind Regards ​Emma With that said, I have forwarded th...

Re: Is 2.5A enough for the Pi 4?

(But the actual wording of your order, and thus the agreement between you, would be of interest here... ) Also, I notice you say " the vendor shipped a 2.5A micro-usb power supply ". Just "a power supply"? Not necessarily an official Raspberry Pi spec Power Supply? The latter, with an adapter, is a...

Re: New Raspberry Pi 4B - nothing but problems

It is the 4GB model With that said, I can't say I've ever seen the low voltage symbol on the desktop As for the power supply, I contacted the vendor who sold the kit, and was told that 2.5A was sufficient. Though I would add that I did not get what I payed for, as the listing showed a 3A type-c powe...

Is 2.5A enough for the Pi 4?

I purchased a Pi 4B board along with the 3A type-C rated power supply - or so I thought. Only to find that the vendor shipped a 2.5A micro-usb power supply with an adapter instead. The board on the other hand is completely unstable - locking up, none booting between restarts etc. I contacted the ven...

New Raspberry Pi 4B - nothing but problems

Hi, I just received a new Raspberry Pi 4B and flashed the latest Debian Buster to a micro sd card and things went downhill from there. The first thing to note is that the unit is sloooooooow - I mean, I can't emphasize this enough - slow as molasses in January type slow... The second thing to note i...
