In Why don't they cloak the jumpers before entering the gate?, one of the commentators says that the puddle jumper does not power the gate.

However, it's established in Stargate SG-1 that the DHD provides power to the gate. There are multiple instances of external power sources (lightning, naquada generators, etc) being used to activate a manually dialed gate (or later via the portable dialing computer).

Each puddle jumper includes a DHD, used to dial the gate without having to leave the confines of the jumper. This is especially important when it comes to space gates.

Is there any in-universe or out-of-universe statement for or against the jumper in SGA being the sole source of power for activating a gate?

Space gates have three power nodes that both power the gate and act as stabilizers. You can see one of them in this image from the Stargate wiki.

You can see the stabilizing in action in several episodes, notably in "38 minutes" (season 1, episode 4).
