Item Condition Brand new
Remarks -This high quality replacement PSU has only one special 20pin connector (32cm long) and is only suitable for the systems advertised. It is NOT suitable for standard ATX or Micro ATX systems. -This item includes the Power supply unit alone. It DOES NOT come with the tray. -Unlike the original, this PSU is not fanless. It has a quite and efficient 40mm fan and extra vent holes on both sides for an improved ventilation (no need to use the transparent plastic shield on our PSU). -It is more powerful for a better upgradeability & system stability. -It has high quality components, is very reliable and has an extremely low failure rate. -The vent holes near the power socket are blocked when installed but the additional large vent hole on the side is sufficient to compensate.
