    Great psu, love the modularity of the cables. Makes cable management a breeze. Comes with 3 pcie cables which is perfect for those of us running the new rtx 3000 series. Only complaint is the cables have two headers per cable while its suggested to run one cable per port. Leaves a messy/unfinished look to your build if you're avoiding spending the extra dollars on cable extenders. Psu is quiet and can't be heard over the rest of my build at all.

    Overall, great value for 850W Gold+. Only downsize are the cables aren't sleeved like other brands (EVGA). Looks a bit, cheap-ish. But, gets the job done. Took 1 star away for the sleeving.

    I upgraded from a low end 450W Corsair to this when I decided to buy my friend's 2080. First of all, the Corsair was still a nice power supply, but this is on a whole other level. To add to that, it comes with an amazing 10 year warranty, I feel very confident using this in my rig. Power cable is thiccc, and component power cables are all black which makes it look cleaner in my mostly blacked out build.

    What can I say, Seasonic is one of OG PSU manufacturer and undisputed top 3 brands when it comes to quality. 10 years warranty definitely gives you a piece of mind that this will last you long enough. Picked 850W in hope it would last long enough till RTX5000 series comes out. Sadly, this was one of the highest wattage PSU available at the time because every miner and scalper are snagging good value PSUs.

    This is honestly the best brand of psu you can buy. Excellent warranty, cables are fine. Don't really get why people complained about it being too loud, its not silent but it also does not make too much noise. If you need a good psu for the new nvida 3000 series gpu, look no further.

    This chonky boi is doing a great job of holding down the fort in my case. I upgraded to a 3000 series card and needed a new power supply and this gets the job done. Upgrading from another Seasonic was super easy because I didn't have to rerun all of the cables, just add the new ones.

    The PSU is next to perfect as far as I can tell. Completely silent with none of those high frequency noises you get sometimes. It does everything it's supposed to, so not much to elaborate on there.

    Rock solid power supply, with great flexibility in its modular cables. The nice thing I like about this Seasonic PSU, is that if you're simply wanting to use it as a secondary PSU to power GPUs, you have up to 5 PCI-E power slots. Super silent as well in the Hybrid mode. Would highly recommend!

    Amazing PSU, it still has not broken down yet which is a good thing. It was either this one or the RMx 850 W. I got the GX-850 for about $135 and snagged this one instead. My old gaming pc was SeaSonic and got that about 4 years ago..I think it was a 620 W 80 bronze or something like that.

    Good PSU but the GPU cable are too rigid

    It's a nice modular PSU. A huge complaint is that all of the 6+2 pin cables have two plugs attached to one side. So if you're using a GPU the cable isn't flexible enough to fix in the the case because it sticks out too far from the GPU. I'd like for them to have two cable that have one connector on each end so it could be more flexible and less bulky to fit into the case. I literally can't close my case door because they stick out too far.

    No, I would not recommend this to a friend

    This power supply is super quiet and It is a really good power supply in my opinion. It powers my RTX 3080 Ti and I am sorry for those struggling in getting a card. However, if it is your plan to get an RTX card. This power supply will get the job done and it is quiet.

    Works as described and with the modular cable set up makes cable management a breeze. Well than enough power to run a 5600x and a b550 running a rx580 with multiple drives with plenty to spare for overclocking everything. Best buy had it at a great price and shipped fast

    I upgrade my old corsair PSU to this one and no complaints. People, make sure to get a gold certified or higher PSU. Do not cheap out on the component that is powering the rest of your PC components. My PC has a PSU shroud so I can’t see it.

    High quality PSU, that will give you room to spare with today's high end GPUs. Runs a RTX 3080 and RX 6800 XT with ease. Recommend anyone to get an 850w+ PSU if running high end graphics. You just spent $600+ on a GPU, don't skimp out on the PSU!
