Glancing over the SilverStone Strider ST405 400W we were quickly impressed by its magnificent-looking surface. This high gloss titanium-black surface is coated with Zinc to allow its impressive appearance to last a great while and not to become prey to scratches and other mishandling. In fact, its surface for the power supply is among the best we've seen in quite a while and is standard throughout all Strider power supplies with the exception for the new SilverStone ST60F 600W. On the back of the ST405 PSU is the power connector, voltage switch (only on passive PFC model), and power switch. As SilverStone strides for the ideal balance of quietness and performance, there is no fan providing for exhaust purposes but there is a wealth of ventilation holes. However, the single 120mm Silverstone fan on the bottom of the power supply with its variable speed design should be able to effectively cool off the power innards as well as pushing out the warm air. On one side of the power supply is a sticker that contains the various wattages and amperage for each voltage rail while the opposite side of the power supply remains bare.
Like previously stated, on the underside of the power supply is a variable speed 120mm fan for assisting in the cooling process. Both the fan and its grill are black to accent quite well with the Titanium-black finish. Popping off the power supply cover, inside everything was well laid out and the heatsinks used were respectable for the PSU size and 400W design. The build quality inside was just as impressive as its external appearance.
As far as the cabling goes, only the two motherboard connections, the ATX12V 4-pin power and 20/24-pin motherboard connector, are sleeved. Unlike the recent phenomenon with modular cable designs for ATX PSUs, and the ST60F, the SilverStone ST405 uses traditional cabling. In addition to the motherboard connectors, there were eight 4-pin peripheral molex, 2 FDD, 4 SATA power, and one RPM fan speed wire connectors. Although there is no PCI Express connection support, the included connectors should be suitable for most setups using less than 400W of power.
