Customer Ratings & Reviews

This PSU is worth every penny if you are running a pc that draws a lot of wattage I would go with this power supply . It’s currently handling my 4090 graphics card and that draws a lot of power . SEASONIC makes some of the best power supplies

Bought in june and put it on the shelf to build my system. Got it down today and put my new system together and it will not power up. So much for buying the best.

I've been using this psu in my 3090ti build with a ryzen 9 5900 for about a year and no problems. Was able to overclock without any issues. powers everything I need with zero issues.

Using it with Asus Strix 3090 liquid cooled rig with AMD 5900x. It is a breeze. Build quality is great and modular cables are very helpful.

So far it's been an excellent PSU. I have this in a system with an i9 10900k and RTX 3080, 64gb of ram along with about 6 HDDs, 3 SSDs and some other USB peripherals and it has no issues - the system is stable. There are enough power connections and cables provided here that I can't see someone needing much more than this. Also, Seasonic has some excellent customer service because they had a form to fill out online to get a new custom 12-pin cable designed for the RTX 3080 out to me within a week, so that I didn't need to use the nvidia adapter for it and could just use one cable straight from the PSU. I also got a bit of a bigger PSU than I needed to keep the times the fan ramps up in hybrid mode down as well, so that probably has some affect on it. I did this because I was worried about reports online about potential noise with the Hong Hua fans that Seasonic has historically used, But this thing has been silent from the start and they either changed those fans or the noise issue has been dealt with because the times it does kick in it's very quiet.

This all started when I decided to upgrade my video card to a GTX 3080 12gb card. I installed it and my computer would spontaneously reboot during gaming. While I had a 850 watt power supply it was long in the tooth and having experienced this years ago with another computer, I started looking for a new power supply. Many reviews later and this highly rated power supply was installed. Well packaged, super efficient, super long warranty, rock steady voltages, quiet, modular, every cable you could possibly need, and best of all no reboots unless I want one. I've had many power supplies over the last 25 years from all the major players, but i always avoided Seasonic due to pricing. Not any more.

Overall great PSU. I only used EVGA PSU for the last 15 years and this time after much research went with the Seasonic. Cables are fully modular and flat except for the main board power cable is round. A PSU at this price range should have all rounded cables. Overall great quality so far powering i9 12900k, asus z690 strix Gaming-E MB, 32 DDR5 ram, and a Evga RTX 3080 ti FTW3 GPU. Plenty of reserve power for upgrades.

Used this to upgrade the PSU in my pre-built. Was having crash issues with the generic 750w running a 3080. But ever since I've installed this I've had 0 problems. King of PSUs

This graphics card is great, epic performance, and super efficient i would recommend to everyone. Don't cheap out and it may help your energy bill.

This thing is a UNIT. It powers everything I need with no hiccups. Would definitely spend the money to get something like this due to the pristine quality.

Excellent PSU. Lame flex incoming: Found out via a couple of Kernel Event 141s that my old 850 watt Seasonic wasn't quite up to the task of feeding a 12900K and 3080ti. Swapped this out and smooth sailing ever since. I don't think I'll need any other power supply for a very long time.

Have been using SeaSonic power supplies for 10+ years, and not a single one has failed. Splurged a bit for my 5900x / 3090 FE build with this 1000W Titanium PSU from SeaSonic, and no surprises, everything is working extremely smoothly. Able to handle all the overclocking I can throw at it, and will continue to be a SeaSonic PSU shopper. SeaSonic also ran a promotion where they gave an FE-compatible power cable. Great customer service on that part! Every other psu company charged $30+ for their FE-compatible cables.

This is a beast of a PSU! The modular cables are perfect for keeping your case tidy by not having unused cables connected. PSU is nice and quiet. This easily powers my i7-11700KF and dual 3090 GPUs.

Seasonic products have great warranties and are extremely reliable. Worked right out of the box no hiccups. Never cheap out on a power supply pick a reputable product. It will last you a long time.

Amazing PSU. My coil whine on my GPU decreased when I upgraded to this powe supply. Saving a tiny bit on electricity and wont need to get a new one for another 10 years.

Just hooked up the PSU and it’s amazing. It has a 12 year warranty from Seasonic and a 80+ Titanium rating making it one of the highest efficiency PSU’s money can buy. Hard to find but other than that amazing! Well worth every dollar.

Best PSU I have ever owned. I had a 1000w psu of a different brand and had terrible coil whine, not with this power supply! Plus a 12 year warranty is nothing to mess around with.

Do you NEED a Titanium 1000W? Nah. But do you WANT a Titanium PSU w/ a 12 year warranty from the best in the biz for your 3090 or RX6900XT GPU? Flex on you PC enthusiast.

Literally, the best power supply I have ever owned, so far I have never heard it, and the random pc shutdowns I am used to having are all gone!

Absolute monster of a PSU. 1000w. Great Price for a Titanium Efficiency Rating. High quality components. 12 Yr Warranty. Packaging is A+. Only complaint is the PSU wasn't assembled right out. It was not flush and one side sat higher than the other. Had to take apart and change how it was assembled to get it to sit right. Otherwise zero issues
