FLEX-650 650W server power supply

The Supersuperuncle FLEX-650 is a new 650 watt server power supply built for XinHang ITX FLEX NAS chassis. It fits small 1U form-factor systems including the K39, K35, S3 and M41M24 models. The unit delivers a rated 550 watts continuous output with a 650 watt peak capacity.

Capacity and headroom

The 550 watt continuous rating supports typical NAS workloads such as multi-drive storage arrays and low-power CPUs in a compact 1U enclosure. Peak headroom of 650 watts absorbs brief spikes during drive spin-up or heavy parity calculations. Builders needing sustained loads above 550 watts or compatibility with non-XinHang chassis should look elsewhere.
