PSU "Schematic" help me understand AC/DC Bridge Rectifiers, Proper Grounding, and Series AC Connections

- list all currents
- Are you skilled in low-noise PSU's?
If not, then this is a shopping question.

Never made a psu in my life but I chose a toroidal transformer to reduce emf, I will also filter the power before and after the buck converters with capacitors and LC filters.. I'm just using chat gpt to understand better. been studying for 40 hours only.. I'll build it myself for better or for worse and implement a slowblow fuse in the beginning of it and a quick blow in the end.. As of now I'm trying to wrap my head around how the bridge rectifier works, if i should split ac cable one and connect that to rectifier 1 ac in 1 and rectifier 2 ac in 1 and put my second 24v wire into rectifier two ac in 2 im wondering if that would create 67DC +/- out of rectifier 2.. this DC will be pulsating so i need to send it into capacitor to have a steady flow to reduce noise, and improve stability, capicitors are rated appropriately.. the 500 rack with everything will draw 5 amps max, the current diodes are rated for 5amps which is kinda tight but its to prevent backflow as im splitting the rectifiers one output from capacitor 1 into 2 buck converters.. Its just is my current understanding of getting higher dc by splitting a 24v cable in two to get 24v to two different places and also attatch 24v_2 into rectifier 2 to get 48v _> 67V DC correct if the transformer can handle the amp pull or is my basic understanding of electronics wrong. As stated I've only studied electronics for 2 days but I'm kinda crazy so perhaps I learn quicker than most or burn down the house, idk. Also heatsinks should be able to manage the overall 25 watts of heat generated from this circuit. Specifically the buck converters that convert electricity to heat to get a lower voltage output.. I think..

Thank you so much for responding, im greatful for any help I can get.
