B320 B340 B545 compatible PSU

This new ATX power supply replaces the FSP200-20SI PS-3251-01 DPS-250AB-71A units used in B320 B340 B545 systems. It is tested working and built for owners who need a direct swap without adapter cables. Buyers with proprietary form-factor cases or non-standard pinouts should verify fitment first.

Thermals noise and power draw

The 200 W and 250 W rated designs deliver stable output for typical office workloads. Normal use keeps fan noise low and temperatures controlled inside the chassis. Power draw scales with the connected components rather than the maximum label rating.
