Kingwin Stryker 500W Fanless Power Supply Review

Almost everyone wants the quietest yet most powerful computer possible. Most components generate noise because of the fans cooling them, or because of moving parts. Obviously, solid state drives have eliminated the necessity for moving parts for storage and liquid cooling can replace fans for most components. However, there’s still one pesky component which still generates noise: the high wattage power supply unit. Fanless PSUs have been around for a while, but they’re generally lower wattage and meant for business machines or ultra-efficient HTPCs.

Kingwin’s new Stryker series of PSUs aims at the gaming market. Its 80PLUS Platinum-certified 500W unit with a five year warranty supplies enough power to drive a medium-range gaming rig and not make a sound doing it. ThinkComputers has the review.

Special thanks to Kingwin for providing us with the Stryker 500W Fanless Power Supply to review.

The Kingwin Stryker’s box displays the unit and prominently shows its wattage and that it’s fanless. In the corner of the box, it also says that it’s 80PLUS Platinum certified. This means that it’s up to 92% efficient at 50% load. It also says on the box that it’s the “overclock version”, claiming it can actually supply up to 600W. The bottom of the box lists the specifications.
