Features

  • High Efficiency, 80 PLUS Gold Certified

  • 135 mm Fluid Dynamic Bearing (FDB) Fan

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 cable It 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.

  • Quality power supply, perfect for high-end GPU's
Style: Focus Size: 1000W ATX 3.0 Gold
I purchased this power supply to resolve issues with my RTX 4090. Some of the issues I was having were: 1.) random black screen with fans at 100% regardless of load, 2.) coil whine, high fan speed, and noise all coming from the power supply 3.) inconsistent power on/off behavior. After quite a bit of troubleshooting and swapping out spare power supplies, I narrowed the cause of my issues down to my power supply being old and not ATX 3.0, PCIe 5.0 rated. My old power supplies had the wattage to theoretically support the power draw of the 4090 but in reality could not reliably deliver a stable 12 volt power rail required by high-end GPU's like the 4090. When I installed this Seasonic Focus V3 GX-1000, the first thing I noticed was the build quality and quietness. The power supply fan is whisper quiet and my GPU stability was immediately noticeable. I ran a few games and GPU stress tests and not a single issue. The other benefit to using an ATX 3.0/PCIe 5.0 compliant power supply is that I can use a single cable for the PCIe dedicated 600 watt power to my GPU instead of using the GPU's 8 pin power adapter dongle. My case looks neater and I don't have to worry about bending the cable. All of the power cables included with this Seasonic Focus V3 is soft, flexible, and rounded. They are long enough to route and cable manage. I do recommend to read the included instruction manual to understand the power supply and its unique functions, and how to connect and install the power supply in an optimal orientation. In summary, this Seasonic Focus V3 GX-1000 deserves 10 stars. It really is at the top in terms of quality and performance, backed by a 10 year warranty. I have no doubt this power supply will last a very long time and I strongly recommend it for high-end GPU's, especially the 4090. ... show more

  • Great PSU
Style: Focus Size: 1000W ATX 3.0 Gold
This PSU was easy to install and has ran great. I was having random reboots while gaming on a old 750W EVGA PSU so I bought this 1000W Seasonic PSU hoping it would fix it. It has fixed my issue but also runs quieter than my older power supply. Comes well packaged with multiple slip bags to store other cables you may not use. Highly recommended. ... show more

  • 10/10 A tier Power Supply with 10 year Warranty!
Style: Focus Size: 850W ATX Gold
This PSU is an A or even S tier unit on most Power Supply Tier Lists. Seasonic know what they are doing when it comes to PSUs and have been in the game for a long long time. Fully modular, 80+ Gold efficiency, small in size to fit into nearly any case, high quality components, the option via toggle switch to enable Eco mode which turns the fan off under low load or disable it which always leaves the fan on, sleeved high quality cables, TWO EPU/CPU connectors for those power hungry chips/boards, 6 total PCIE connectors for as much GPU power as you want, several diff length sata cables, great 9/10 and 10/10 reviews by most every critic/user/tech site, and best in class 10 YEAR warranty!!! What more could you ask for in a PSU! It’s small, quiet(I’ve never heard it at all), looks good, efficient, fully modular, and has great reviews with a decade long warranty. All this with amazing pricing often less than PSUs with lower quality and much shorter warranty. You want a solid PSU behind a name you can trust that will last you a decade? Here ya go. Enjoy the pictures and thanks for reading. ... show more

  • Great PSU
Style: Focus Size: 850W ATX 3.0 Gold
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.

  • Solid PSU with stable performance
Style: Vertex Size: 1000W ATX 3.0 Gold
Got this PSU to replace a dying EVGA PSU and it has done everything I could ask. Runs quite (by my standards) and provides stable power to my hungry 3080 (can draw up to 400w). It’s built really well and looks great. The only thing I don’t really like is how to cables are sleeved. They are independently wrapped which makes the 16pins etc a little messy. But, plenty of Velcro comes with it. ... show more

  • It’s all about the cables!
Style: Focus Size: 1000W ATX 3.0 Gold
Seasonic is essentially the gold standard for PSU’s. You can find a lot of excellent in depth reviews on this unit that prove it’s excellent performance. However, there is one aspect of every review that is always overlooked, the cables! I previously had a very expensive PSU from another brand. The reviews were stellar so I bought it without hesitation. The cables were terrible, with tons of redundant splits/connections, with stiff unbendable sleeves. Aftermarket cable replacements were pretty much non existent. This Seasonic PSU has fantastic cables! They are durable, very flexible, with a huge variety of individual cables with great connections. Most importantly, Seasonic has stuck with this pin layout for a long time. This makes replacing or upgrading the cables a much easier and cost effective proposition. ... show more

  • Great quality, quiet power supply
Style: Vertex Size: 750W ATX 3.0 Gold
I bought this to upgrade an old power supply in my Unraid storage server. Installation was easy, and the cables are good quality, not super stiff. I have owned and had this in operation for a few months now, with no issues to speak of. Some people online mentioned they experienced coil whine or noise with the Vertex GX power supplies. Mine is quiet, no noise apart from the cooling fan. Which is not noticeable. Overall very satisfied with this power supply! ... show more
