SMUGDESK 5mm Mini 4Pin to Dual 15Pin SATA Power Extension Cable 45cm for Lenovo M410 M415 B415 510SA

Lenovo proprietary mini 4‑pin power adapter

This custom cable converts the unique 5 mm four‑pin header found on Lenovo M410, M415, B415 and 510SA motherboards into two standard 15‑pin SATA power connectors. It lets owners of those compact desktops add two 2.5‑inch SATA SSDs or hard drives without modifying the chassis. The 45 cm total length (25 cm main lead plus 20 cm branch) provides enough slack for tidy routing inside the small case. No soldering or extra drivers are needed for the upgrade.

Limited to Lenovo small‑form‑factor boards

The mini 4‑pin male plug only fits the dedicated 5 mm power header on the listed Lenovo models; it will not mate with standard large four‑pin Molex connectors or any other motherboard. The adapter supplies power only, so separate SATA data cables are required for each drive. Current capacity is bounded by the 18 AWG pure‑copper conductors and the motherboard header’s own rating, making it suitable for typical 2.5‑inch SATA devices but not for higher‑draw components.

18 AWG copper with molded strain relief

Thick 18 AWG copper wires deliver steady current to both SATA ports while the molded boots on every connector absorb bending and pulling stress during installation and later maintenance. The plug‑and‑play design means the mini 4‑pin end seats directly into the motherboard header and the two 15‑pin female ends accept standard SATA power plugs. This construction supports repeated drive swaps inside the tight confines of Lenovo’s compact desktop chassis.
