SilverStone today introduced the DA1650, a 1650 W high-end PSU. With a length of 180 mm, the DA1650 has some of the highest power densities on the market, more so given that it's a fully modular PSU (modular cabling adds to the length of a PSU). The extreme Wattage enables the PSU to run completely fanless up to 30% of its capacity or 495 W. Under the hood, the DA1650 features a single +12 V rail design, with a gargantuan 137.5 A rail. It features DC-to-DC switching, active PFC, and most common electrical protections, against over/under-voltage, overload (if you try to crank a truck with this thing), overheat, and short-circuit.

The SilverStone DA1650 offers 80 Plus Gold efficiency, along with ETA A and Lambda S+ certifications. The PSU is designed for 24/7 continuous operation in an environment with up to 50 °C ambient temperature. It uses a 135 mm fluid-dynamic bearing fan to keep cool. Connectors include one 24-pin ATX, four 4+4 pin EPS, twelve 6+2 pin PCIe power, sixteen SATA power, six Molex, and a Berg.Update Aug 27th: SilverStone informed us that the DA1650 will be backed by a 5-year warranty, and priced at USD $330.
