Seasonic Focus GX-850 ATX 3.0

I’ve been using the Seasonic Focus GX-850 for about a month now and it’s been working great. I’m running it with an RTX 5080 Founders Edition, and I’ve had no issues at all so far. Installation was easy thanks to the fully modular cables, and it runs quiet and stable, even under load. It’s ATX 3.0 / PCIe 5.0 ready, so it feels like a good fit for newer GPUs. Overall, it’s been reliable and does exactly what it’s supposed to do. I’d definitely recommend it if you’re building a modern PC and want a solid power supply.

I'm a Seasonic fan period. They don't charge more for way less like their competition. My day job is in computers and Seasonic can be relied on to deliver power under load that they are rated for. I've installed hundreds of power supplies for my job and at home and won't go back to Corsair or any other brands that have burned me for the previous twenty years before I switched to Seasonic. Seasonic are definitely the Toyota of PC Power supplies.

Exceptional power supply, super quiet. Does a fantastic job - the modular cables are easy to plug in and it comes with a 600w cable for newer GPUs.

I love seasonic! Great hardware and this is my second one I've bought for a build. Whisper quiet and low heat.
