I got mine as a DIY kit, and decided to buy RAM, SSD and power adapter separately, which means I don’t have a FW power adapter. I’m now questioning my life choices, and probably just going to buy a FW one

I bought it with Amazon prime, so I’ve already returned it due to the easy returns process

Yep, indeed I have

I’m in UK. I agree with Teknet being a bit unheard of, but reviews were very good. I was more surprised about the Anker failing yesterday as I’ve heard good things about them

How do I know if there are ‘incompatibilities’? If the charge light is on is it safe to assume it’s working?
