Description

The Seasonic FOCUS GX 80 PLUS® Gold certified power supply is rated to achieve 90 % efficiency at 50 % system load.ATX 3.0 and PCIe Gen 5 ready with 600 W 12VHPWR Gen 5 cableIt is a flexible solution that optimizes cable management and reduces clutter inside the computer case.This ultra-high power density, small footprint (140 mm deep) power supply is an ideal choice for all cases, especially compact ATX ones.The lubrication inside the FDB greatly reduces friction, vibration and noise and increases the lifetime of the fan.The industry's first three-phased advanced thermal control achieves an ideal balance between silence and cooling at all loads via three operational stages: Fanless Mode, Silent Mode, and Cooling Mode. The benefits of this system are:- The Fanless Mode provides unsurpassed silent performance. - Heat dissipation is optimized while noise output is kept at the minimum. - The lower number of fan rotations extends the life of the fan. If the PC case requires constant active cooling, there is a switch at the back of the power supply which allows users to turn off the hybrid mode and have the fan run at all times. Top-grade, Japan-sourced components extend product life and ensure operation stability under extreme conditions.Improved load regulation reduces voltage variations to provide smooth and stable operations. Enhanced +12 V current capability broadens utilization possibilities.Superior dynamic response and greater system stability maximize the 12 V DC rail output.Sea Sonic's engineers have implemented a new design feature, where instead of cables, the back panel and PCB (Printed Circuit Board) are connected by a copper plate. This breakthrough solution not only lowers the chance of production errors during manual insertion but it also improves output power quality.Gold plating reduces current transmission resistance and increases efficiency.The PVC embossed and insulated cable has excellent flexibility, durability, and aesthetics and it meets the requirements of international safety standards. Complimentary cable combs are included in the packaging to improve cable management.Our commitment to superior quality.

  • Great PSU
I am happy I purchased this one. The price was fair, great warranty, it’s is very quiet, no smell. Looks like a normal PSU, the modular cables made the install really easy. Purchased from Amazon because the other place was charging a ridiculous amount for shipping to an FPO.

  • Great PSU, never had to think about it once since installing it
I bought this to replace an MSI MAG 850GL, which was an incredibly noisy PSU without any real semblance of a fan curve. This PSU, however, is perfect. Even on the standard fan mode (as opposed to the semi-fanless hybrid mode), it makes no discernible noise when the rest of my PC's fans are turned completely off. It looks great, the build quality is solid, the cables are a much higher quality than what comes standard with most other power supplies, and it's got a solid warranty as additional reassurance. ... show more

  • QUIET!!! Does Everything as Advertised
Had to return another PSU because of coil whine and purchased the Seasonic Focus V3 GX-850 80+ Gold instead. WHAT A BLESSING! This thing is completely silent compared to the other PSU I purchased. I would highly recommend this product for your PC.
