8Pin mainboard + 4Pin CPU connector

The exclusive 8Pin mainboard connector paired with a 4Pin CPU plug matches the original wiring layout exactly. Multiple SATA ports support the standard drive complement. This connector arrangement is the single specification that decides whether the adapter fits your motherboard.

240W continuous for office workloads

Rated at 240W continuous output with a stable +12V rail, the unit handles daily office desktop running and 24/7 operation. Multi-layer OVP, OCP, SCP and OTP protection shields the mainboard and storage from voltage spikes and short circuits.
