Graviton GPS-550LB D server power supply 550W 80 PLUS Bronze

SKU CH-SQT6-D56GH

550 W server power supply with 80 PLUS Bronze efficiency, active PFC, and 100-240 V input

  • 80 PLUS Bronze certification reduces energy waste
  • 550 W continuous power with 650 W peak capacity
  • Active PFC corrects power factor for stable delivery
  • Non-modular design keeps cabling simple and secure
  • 5 SATA connectors plus 2 six-pin GPU plugs

Server power supply 550W Bronze

This unit is a non-modular server power supply rated at 550W continuous output with an 80 PLUS Bronze efficiency certification. It delivers up to 650W peak power and operates on a universal 100V-240V input with active PFC. The design uses a standard 20+4 pin main connector and includes two 6-pin PCIe connectors for graphics cards. It is intended for desktop and server applications requiring a fixed cable set.

Fits standard ATX server chassis

Suitable for builders replacing a Delta RS-550 compatible unit in a rackmount or tower server that accepts a non-modular PSU with a D-type bus interface. The supply provides five SATA power ports and an 8-pin CPU connector for typical storage and processor configurations. Not suited for systems requiring fully modular cabling or higher continuous wattage than 550W. Buyers needing redundant hot-swap frames should look at a different form factor.

550W continuous with 650W peak

The single specification that decides fit is the 550W continuous rating combined with a 650W peak capability. If the target system draws more than 550W sustained load, this supply will not support it. The 80 PLUS Bronze rating confirms baseline efficiency at typical loads. Verify that the fixed 20+4 pin, 8-pin CPU, two 6-pin PCIe and five SATA connectors match the backplane and component requirements before purchase.

Domande su questo articolo

What continuous power limit applies when the GPS-550LB D runs under sustained load?

The unit is rated for 550 W continuous output, with a peak capacity of 650 W for short bursts.

How loud or hot does the non-modular GPS-550LB D get during all-day operation?

Active PFC and 80 PLUS Bronze efficiency reduce waste heat, so the internal fan runs at lower speeds for quieter 24/7 use.

Which existing cables or connectors must my server already have to install this PSU?

You need a motherboard with a 20+4 pin ATX socket, an 8-pin CPU power header, two 6-pin PCIe plugs for graphics, and five SATA power ports for drives.
