Hyperion 0610i Charger power supply

[tc3_racer_001]

ok, this is something ive been thinking about too... ive got 3 modded pc supplies (after my 12A one blew up 4 times, running 8A...GRRR free replacements wore out after that :D

anyways, ive got an antec earthwatts 500A one, very good psu, and holds the voltage 100x better than my other ones. (with the same setup) anyway, its got 2 12v rails, rated for 19A and 17A. (one for CPU, and the other for everyting else i assume) ive pulled it apart and when a heavy load (20A of charging power, much over the rated i know, for a short (20 seconds) i noticed that it dropped down to 11.98 (understandable) BUT, the other unloaded rail also dropped to 12.24 or similar... which means they are somehow connected (use only 1 transformer or something, i have no idea)

but the question i want to ask is, what would happen if i joined the 2 rails together into 1 output, and had a ground. then i would have a 30A supply. which would be great for the 250w charger. my other option is to buy 2 of the other chargers in that range (forgot the name) and use 1 on each rail...


any suggestions/concerns (didnt seem like a great idea until i had some opinons, not keen to blow up a $90 supply...
thanks, and sorry if its off topic!
