R520 G7 750W Hot-Swap Redundant PSU

The Graviton R520 G7 750W is a 2U server power supply designed for the R520 G7 platform. It ships with a matching power cage and supports hot-swap replacement for continuous uptime. Redundant operation allows a second unit to take over instantly if the primary fails. Buyers needing a non-redundant desktop PSU or a different form factor should look elsewhere.

2U Form Factor and Cage Connector Limits

The unit fits a 2U chassis and connects through a dedicated cage that provides a 24-pin, two 8-pin CPU and two 10-pin connectors. This fixed pin-out restricts use to systems wired for that exact cage layout. Builders working with standard ATX 24-pin only backplanes or proprietary blades without the cage cannot install this supply.

80 PLUS Gold Efficiency at 750W

The supply delivers 750 watts with 80 PLUS Gold certification across a 90-264V input range. Active PFC maintains a high power factor under varying loads. This efficiency level suits dense server racks where heat and electricity cost matter. Buyers who require platinum or titanium ratings for stricter efficiency targets will need a different unit.

Questions about this item

Which part number should I select for the R520 G7 server, PS-2751-1F-LF or PS-2751-2F-LF?

Both part numbers refer to the same 750W hot-swap supply that fits the R520 G7; choose the one that matches the label on the unit you are replacing.

What does the 750W rating mean when the supply is installed in an R520 G7?

It delivers up to 750 watts of continuous output to the server's 24-pin, dual 8-pin CPU and twin 10-pin connectors while operating from 90-264V mains.

How does the 80 PLUS Gold certification affect efficiency in daily use?

The supply meets 80 PLUS Gold efficiency levels, so it wastes less power as heat across typical server loads while maintaining active PFC.
