SEMI-FANLESS FULL-MODULAR 80 PLUS GOLD POWER SUPPLY Power Up The V Gold - v2 series delivers a top-shelf power supply unit in 550, 650, 750, and 850 wattage levels. It offers an 80 PLUS Gold efficiency rating, full-modular cabling, optional semi-fanless operation with a hardware based hybrid switch, a 135mm FDB fan, 16AWG PCIe high efficiency cables, and a 10 year warranty. This series has brought together a number of innovations and improvements from past products to form a PSU that meets all your needs. The 100% Japanese capacitors, half-bridge LLC resonant converter, and DC-DC circuitry work together, resulting in a product that even the pros can respect. 80 Plus Gold Certified The efficiency of your power supply unit is important because it directly affects you system's performance and your power bill. The efficiency rating does not reflect the quality or reliability of a PSU. It only reflects the unit's ability to move power from the wall to your components. The higher a PSU's efficiency is, the lower the total amount of power it needs to power your system. The V Gold series has an 80 PLUS Gold efficiency rating, meaning it has a guaranteed typical efficiency of 90%. Performance Driven Topology The V Gold - v2 is a professional grade power supply unit made for the normal user. It's more than just the 80 PLUS Gold efficiency rating. It's the performance, stability, reliability, lifespan, and so much more. That quality starts with the technology used on the inside. The half-bridge LLC resonant converter and DC-DC technology, made with 100% Japanese capacitors, work together to create a PSU that offers reliable and stable voltage outputs for safer, more reliable performance and higher efficiency. A Bigger, Better Fan The V Gold - v2 keeps cool under pressure. The fluid dynamic fan bearing creates less friction, making it great for low RPM operations. This technology, combined with a larger 135mm fan, keeps the fan running smoothly and efficiently for longer, keeping the noise level down and extending the lifespan of the PSU. The cooling system isn't just bigger, it's better. And when you aren't pushing your system too hard, the semi-fanless mode will keep the unit completely silent when under 40% maximum load. The built in analog hybrid switch allows you to disengage fanless mode at any time with a simple button press for testing, debugging, or simply achieving maximum cooling at all times. Full-modular Cabling Cabling is often the most troublesome part of building a PC. The V Gold can't solve all your cabling problems but it's an excellent place to start. With full control and customization of your cables, you don't have to have excess cables cluttering your PC. This level of control can reduce cable bulk which can increase airflow and make your system look as great as it runs. And with the included 16AWG PCIe cables, you'll get increases to both efficiency and style. Improved PCIE Cable Conductivity The V Gold - v2 series comes with 16AWG PCIe cables. These are thicker than current industry standard 18AWG cables, meaning less heat resistance during use. The reduction in heat resistance improves efficiency and stability so your components can get the most out of that 80 PLUS Gold rating. As an added bonus, the lower resistance means less ambient heat in your case being expelled from your cables, making your entire system safer and cooler than the same setup with standard issue cables.
