As mentioned previously, another notable feature of the ST65F-G is its short 140mm install depth, a nice bonus for a fully modular power supply of this wattage rating. This will prove very beneficial to those looking to cram as much power as possible into small sized cases. Although it ships with the standard 500mm-550mm cable kit, SilverStone's optional PP05 short cable set is available. The UL identification ID E313296 specifies SilverStone as the manufacturer, however as with previous Strider Gold models, the components and construction of the unit point to Enhance as the OEM.
Unlike some of its larger siblings, the ST65F-G uses a smaller AD1212MS-A71GL fan. This is an ADDA 120mm 12v Medium speed, sleeve bearing, 25mm thick, seven blade, IC controlled fan capable of up to 80 CFM at 2000 RPM and 38 dB/A. To be classified as 80Plus Gold, a power supply must meet a minimum of 87%/90%/87% efficiency at 20%/50%/100% load. According to the 80Plus Test Report, the ST65F-G yielded 90.6%/91.6%/87.9%, slightly better than the ST75F-G Evolution we tested last year. The low-load efficiency looks especially promising, however 80Plus also recently began testing power supplies at just 10% load, and although not required for certification, the ST65F-G efficiency does roll off significantly to only 86.8% at 10%.
Let's get the SilverStone Strider Gold 650W installed and tested.
