Following the recent announcement of the power supply ST30SF V2.0 Taiwanese company SilverStone PSU continued modernization of the SFX form factor, releasing ST45SF V3.0 device 450W rating. For the first time on the SilverStone ST45SF (model SST-ST45SF with “stuffing» FSP), we wrote back in April 2010 year. Later, he published his second version, and now – the third. The new power unit uses the OEM-platform Sirfa (company, also known under the retail brand High Power) and is designed for a permanent load of up to 37.5 A / 450 W at 12 V. For the model lines ST45SF V2.0, this value is 36 A / 432 watts. As a newcomer, and his predecessor, to meet the standard ATX12V v2.4 and energy efficiency 80 PLUS Bronze. However, the efficiency of the passport ST45SF V3.0 networks 230 is still above the average of 1%: with a load of 20-100%, it varies from 85% to 88%
The new fully painted in black color, is characterized by dimensions of 125 (L) × 100 (W) × 63 (H) mm and weighs 1.1 kg – 100 grams more than the previous model. For its installation in the ATX-case (in place of the power supply 86 mm high) enough to complete the metal plate.
The device SilverStone ST45SF V3.0 supports an active power factor correction mechanism (Active PFC) and can operate with input voltages from 90 to 264, as well as the environment temperature from 0 to 40 ° C 24/7. According to Specification PSU components are protected against short circuit, overvoltage and undervoltage, overcurrent and over-capacity.
Externally, the third version is different from the second ST45SF presence braid cables and larger (92 mm) fan. Last mode operates from about 600 to about 2200 rev / min. At minimum speed the noise level is 18 dBA. It should be noted that the “propeller” accelerated to 1000 rpm under a load of only about 70-75%. By the way, along the lines of 3.3 V and 5 V is the sum should not exceed 110 watts (at ST45SF V2.0 – 120 W).
All cables have ST45SF V3.0 block non-removable, their length -. Not less than 30 cm set of connectors in the new PSU as follows: (20 + 4) pin ATX, (4 + 4) pin EPS12V, (6 + 2) pin PCI-E Power, three SATA Power, two Molex 4-pin and one FDD Power
Previously, the warranty on the above-described power supply will be for three years, and its cost is comparable to that of the device ST45SF V2.0, which is now available in Western European retail at a price of € 63 .
