Ruth's sister EFRP-603 600W Hot-Swap Server Power Supply 1U

600W 1U Hot-Swap Server PSU

This 1U form-factor power supply delivers 600W to rack-mount servers and supports hot-swap replacement without shutting down the chassis. Active PFC corrects the power factor across a 100-264V input range at 47-63Hz. A fixed 20+4 pin main connector, one 4-pin CPU connector, six SATA connectors and a single 6-pin graphics connector are provided. It is built for administrators who need redundant, swappable power in a standard 1U bay.

Sustained-load behaviour

Active PFC maintains efficient power conversion during continuous server operation rather than only during brief peaks. The 10-5A input current range accommodates varying line conditions while the unit stays within its 600W rating. Non-modular cabling means all leads are permanently attached, reducing connection resistance but requiring cable management in dense racks. No 80 PLUS level is declared, so efficiency under constant load should be verified against the specific deployment environment.

Replacement scope

This unit replaces a failed or capacity-limited 1U hot-swap PSU in servers that use the same 20+4 pin, 4-pin CPU, SATA and 6-pin GPU connector layout. The upgrade is worthwhile when the existing supply cannot deliver 600W continuously or lacks hot-swap capability. It is not suited for systems requiring modular cables, higher wattage, additional GPU power connectors or a certified 80 PLUS efficiency tier. Builders needing more connectors or a different form factor should look elsewhere.
