Comparison between 800W65V and RD 1200W68V switching power supply
S-800-65 is NVVV 65V 800W power supply, and RD-1200-68 is RD 68V 1200W power supply. We will disassemble them and show you the difference.
Overall comparison: There are obvious jumper Wire on the 800W power supply, and it uses green single-sided circuit board, half bridge type topology, and the use of low-cost components make the PSU more affordable when the performance is ensured. The 1200W power supply uses a black double-sided circuit board, which has better soldering performance. It uses a 2-transistor forward topology structure, and the used components are more abundant and have a longer service life. This two power supplies are glued at the large capacitor and inductor positions to fix them, both can work at full load for a long time when testing performance, which is recommended.
