Ruth's sister 550W Flex 1U PSU

This 550-watt Flex 1U power supply fits desktop systems that require a compact form factor. Full modular cabling lets you connect only the leads your build needs. Active PFC and 80 PLUS Gold certification indicate efficient power conversion across the 95-264 V input range.

Two SATA and 8-pin GPU cables included

The bundle provides two SATA power connectors for storage drives and an 8-pin connector for a graphics card. A 4-pin CPU power lead and 20+4-pin ATX connector cover the motherboard. No extra cables ship in the box, so plan for any additional peripherals.

550W rated output with 650W peak

Continuous power is rated at 550 watts and the unit can reach 650 watts maximum. Builds that demand sustained loads above 550 watts should choose a higher-capacity supply.

Questions about this item

Which cable will I need to replace if a SATA drive fails?

The unit includes two SATA connectors; only the drive's own data cable would need replacement.

What limits output when the supply runs continuously at full load?

The 550 W rated power is the sustained limit; the 650 W peak is only momentary.

How much heat and noise should I expect from the 1U form factor under all-day use?

The 15 × 4 × 8.2 cm chassis with active PFC and Gold efficiency keeps waste heat low, so the small fan stays relatively quiet.
