Over 29 years presence in the market of computer power supplies Taiwanese company Seasonic Electronics has established itself as a manufacturer of high quality and reliable products. Its units are sold not only under its own brand, but also supplied OEM-partners, which include a fairly well-known players from the industry power systems. For example, sources of production Seasonic offers own-brand company Antec (series EarthWatts, NeoHE, TruePower Trio), a company PC Power & Cooling, part of the OCZ Technology Group (Series Silencer), the company Silver Power (model SP-SS500), a company Corsair (Model VX450W, HX520W, HX620W, TX650W).
In late summer, the Taiwanese manufacturer announced the launch of a new series of blocks S12D, focused on computer enthusiasts in need of quality nutrition for large modern systems based on multi-core processors and NVIDIA SLI configurations, and ATI CrossFire. Announcement was accompanied by a statement soon start selling debut models of 750 and 850 Tues And so, judging by the range of some foreign online stores, the company Seasonic fulfilled its promise. Thus, on the virtual shelves of the famous American magazine Newegg.com younger model Seasonic S12D 750 Silver is offered for $160, the elder S12D 850 Silver sold at $20 more expensive. Prior to the domestic retail market, apparently, new products not yet been reached.
The list of the main advantages of the debutants S12D series should include support for the latest versions of standards ATX12V V2.3 and EPS 12V V2.91, the ability to work in a wide input voltage range 100-240 V, a high loading capacity, high efficiency, low power consumption in standby mode, a small noise. The presence of certificate 80 Plus Silver said to belong to the last generation of "green" products. Scheme of active power factor correction (Active PFC) provides the power factor (PF)> 0,9. Efficiency of new sources is at the level of 85%, reaching the most favorable conditions for measurements around 90%.
As befits a high-level blocks, the first representatives Seasonic S12D series are equipped with stabilizers to DC converters (DC-DC converter), which allow to achieve better stability of output voltages as compared with decisions on magnetic amplifiers. The deviation from the nominal values should not exceed 3%. Computer power supplies operate in harsh temperature conditions, so it seems justified to use electrolytic capacitors with high operating temperature of the production of the Japanese company Chemi-Con. In filters for high-current circuit 12 in the installed reliable solid capacitors.
Proprietary cooling system S2FC (Smart & Silent Fan Control) involves the use of a quiet fan of large diameter and temperature control circuit, which operates on a special algorithm, the optimum in terms of balance between noise and performance. Seasonic engineers used 120-mm fan with the original shape of the blades San Ace Silent Fan from the company Sanyo Denki. Cable set new units include everything necessary for modern systems, including the 6-pin and 8-pin PCI-E connectors for additional power supply cards. |
