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%.
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.
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.
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.
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.
