    • Seasonic for life
Style: Gold Full-Modular
Fantastic, easy installation. Power cables were long enough to let me easily cable-manage even in my super-ATX case. Love the little things, like the cable ties that come with the PSU. They didn't have to include that, but they did because it's Seasonic. PSU is inaudible, but powerful. If I ever have to replace this, it will be with another Seasonic. ... show more

Easy to install, cables are easy to use especially thanks to the fully modular part. Comes with all cables needed and more. Design is good and sturdy. A friend reccomended seasonic, says he has used them for a while and never had issues. I got the 1000watt for future upgradability since it wasnt that much more money, and they have a ten year warranty so it's great for future proofing. I posted a video of the build I did with this power supply if any one wants to see more like what I used it for/with, unboxing, installation, powering on, usage, etc. video title: Carisneat123 | First PC Build | goodbye low fps gaming ... show more

    • Great PSU!
Style: Gold Full-Modular
The warranty is great and the product is of great quality! I've bought many different brands of PSU's in the past and it's crazy how high the failure rate can be on some of the big name budget offerings. I finally bit the bullet and bought this for longevity. It's holding up great with my 13700k and 3080 and I trust that it will be in good working order for years to come. The warranty brings even more relief as it's one of the best in the industry! Cannot recommend enough. It pays for itself over time by simply being reliable! ... show more

I've been a Seasonic customer since the days after PC Power & Cooling went sideways. They always work ...for years. Not sure if there's ever been a failure.

    • Exceptional PSU ✔️
Style: Focus 750W Gold
This Seasonic PSU has virtually imperceptible inductor noise, at much higher and less perceptible frequencies. Relative to the old PSU the Seasonic is as stable and accurate as it gets. Below 12.1v idle and above 11.9v under load on the 12v rail, no significant change anywhere else. Not seeing any major fluctuations although I haven't scoped it for ripple. The fan is noiseless from what I can tell. The cabling is high quality and independently installed, resulting in less clutter after the build. It may be four years old, but it is a premium PSU. A very good purchase. 👍 ... show more

    • Sends a power surge through my battery surge protector that shuts of my cable when powering down.
Style: Focus 850W Platinum
Sends a power surge through my battery surge protector that shuts of my Roku cable when powering down. Doesn't seem to be harming anything, but kinda concerning. Just annoying and I hope it doesnt cause problems later down the road. Very quiet and seems durable.
