Compact 1U Flex server PSU

This 1U Flex power supply delivers a continuous 500 W and a 550 W rating for dense ITX and mini-server builds. Its 150 by 81.5 by 40 mm footprint fits K39, A4, S3 and G5 style cases while accepting 90 to 264 V input for worldwide use.

Full modular cable set

Full modularity means only the required leads stay inside the chassis, reducing clutter in tight enclosures. The bundle includes a 20+4 pin motherboard cable, an 8 pin CPU cable, two 6 pin GPU cables, two SATA cables and a 4 pin to IDE adapter.

80 Plus Gold efficiency and protection

The unit meets 80 Plus Gold certification with up to 85 percent efficiency and low output ripple. Each rail carries over-voltage and short-circuit protection, and the 4 cm fan has passed a 50 °C aging test rated for more than 80 000 hours of life.

Questions about this item

How long is the 4 cm fan rated to last before it needs replacing?

The fan is tested for more than 80KH hours of high-temperature ageing, so it should run for years in continuous service.

What limits output first when the supply runs at full load for hours?

The 550 W rated power ceiling is reached before any thermal or current limit on the 12 V rail.

How much heat and noise does the 4 cm fan produce in all-day operation?

A 40 mm fan spinning at server speeds moves enough air for 550 W but will be audible and exhaust noticeable heat from the 150×81.5×40 mm chassis.
