Graviton EFRP-603 600W 1U server PSU

The Graviton EFRP-603 is a 600 watt hot-swap power supply built for 1U server chassis. It accepts 100 to 264 volt input at 47 to 63 hertz and uses active power factor correction. A 20 plus 4 pin main connector, a 4 pin CPU connector and six SATA power ports supply internal drives and boards. The unit is non-modular and carries an 80 PLUS certification listed as other.

Replaces failed or ageing 1U hot-swap units

This supply fits the same 1U hot-swap bay as the original EFRP-603 module, so a direct swap restores redundant power without rewiring. The jump is worth it when the existing unit shows fan noise, voltage drift or has lost hot-swap functionality. Six SATA connectors support current drive counts, while the single 6 pin graphics connector limits GPU upgrades.

Suits 1U server operators needing a like-for-like

IT teams maintaining homogeneous 1U racks can keep this model on the shelf for immediate replacement. Builders who need modular cables, multiple GPU power connectors or higher efficiency ratings should look at a different platform. The non-modular design also makes cable routing less flexible in custom chassis.

Questions about this item

What 1U server chassis depth and hot-swap backplane does the EFRP-603 600 W unit fit?

The supply is a 1U hot-swap module rated for 100-264 V, 47-63 Hz input and slides into a matching 1U redundant backplane.

Which cables must be seated first when installing the non-modular EFRP-603 in a live server?

Connect the 20+4-pin motherboard header, the 4-pin CPU power and the 6-pin GPU power before sliding the unit into the hot-swap bay.

How often should the internal fan and electrolytic capacitors be inspected on a continuously running EFRP-603?

Schedule a visual fan check and capacitor inspection at regular service intervals; the non-modular wiring makes internal access straightforward.
