Thinking of getting a second charger (to be my primary), recommendations?

There is one with 70 amps on the 12V rail.

The difference is that many of the newer, high output power supplies use multiple 12V rails. Since I didn't want to deal with the complication of possibly having to parallel those into one output (and not knowing the power supply would be OK with me doing this) under the search I set the filter to show only power supplies with a single 12V rail. And a 650W power supply with only a single 12V rail will have some hefty current ratings.
