SILVERSTONE VIVA 750W 80+ Bronze Non Modular ATX 2.0 Power Supply

The SilverStone VIVA 750W (model SST-VA750-B) is an ATX form-factor power supply certified to the 80 PLUS Bronze efficiency standard, delivering between 82% and 85% efficiency across 20% to 100% of its rated load. Built around a single +12V rail capable of supplying up to 740 W, it is well suited for mainstream desktop builds that include a mid-range discrete GPU, multi-core CPU, and associated storage peripherals. Cooling is handled by a single 120 mm fan with a rated minimum noise floor of 18 dBA, making it an unobtrusive choice for home office and study environments where acoustic comfort matters. The non-modular cable harness ships with flat, all-black cables that sit closer to surfaces and route more easily through tight chassis spaces than round alternatives. A dual CPU power connector arrangement — two 4+4-pin EPS leads — ensures compatibility with high-end motherboards that expose both CPU power headers. The unit carries Active Power Factor Correction (PFC > 0.9 at full load) and a universal input voltage range of 100 – 264 Vrms at 47–63 Hz, making it suitable for use anywhere in the world without manual voltage switching. Protection circuitry covers over-power, over-voltage, and short-circuit events. SilverStone rates the MTBF at 100,000 hours and specifies continuous output at up to 40 °C ambient, aligning with typical enclosed-chassis temperatures during extended workloads.
