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.

This is the best power supply if you are looking for one of the most reliable, efficient, and versatile options on the market. This power supply is fully modular which makes cable management a breeze when only using the cables you absolutely need. It also includes both standard PCIe power cables in addition to the 12VHPWR Cable that most newer NVIDIA graphics cards use. The cables themselves are well made, and they fit the aesthetic of most systems without the need for cable sleeves or extensions.For my system, this has powered everything effortlessly without any crashes, performance drops, etc. The power hungry parts in my PC are a Ryzen 7 7800X3D and an RTX 4080 Super which it handles just fine along with all the other components. I am not much of an overclocker, but I have found that it handles increased power limits on the GPU just fine too.The power supply is very efficient and doesn't waste or use any additional power than what is needed, and it has worked great for me in the few months I have owned it. I like that it includes all the cables needed to support a triple 8-pin GPU power connector, two CPU power connectors, the 12VHPWR cable, as well as all the cables for powering accessories and storage drives with the Molex and SATA cables.Overall, there really isn't much to say other than this is a very high quality power supply that should more than hold up for several years before a replacement is needed. I am very happy with it and I highly recommend it!

The psu works great, low noise, nice looking and very flexible cables.

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.
