Dell T310 Server Power Supply 400W

This 400 watt unit is a direct replacement for the Dell PowerEdge T310 server. It matches the original A400EF-S0 and D400EF-S0 part numbers along with the R101K and N884K references. Administrators maintaining existing T310 infrastructure can install it without configuration changes.

Proprietary Dell T310 form factor limits reuse

The power supply uses a Dell-specific mechanical and electrical interface that only fits the T310 chassis. It cannot be adapted to standard ATX cases or other server models without custom modification. Buyers needing a generic redundant supply or a unit for a different platform should select a different product.
