Just a heads up. I've had two builds now where I get everything boxed up and the the 9V power barrel doesn't fit into the jack! I just went through my stash and found 5 jacks out of ~15 that are too small to accept my DC adaptors and 1 that was way too big. I'm checking them before instal from now on.
The jacks I'm talking about are the innie 2.1mm power jacks (SKU A-2237). I checked all my outies and they are fine.
Wow, thanks for the heads up. Would suck to get it all boxed up and then have to dig it back out.
Just found out that there are 2.5mm jacks (I never noticed that). I must have ordered the wrong ones :P
Same thing happened to me. Didn't even know they carried 2.5mm barrel jacks and ended up with a whole bag of 'em.
I've done the same. I think they're typically used for AC plugs.
