Exactly what you get and well worth it!
Runs great. Fantastic warranty. Comes with all you need just can’t fit in place of a tiny PS. It’s full size. Great price especially with a Longer than average warranty. If you have a newer case ( not like smaller Dell or such it takes almost no time to install. Even comes with the new 12pin connector for the latest and greatest GPU. As far as heat, far less of a problem than cheaper power supply’s. I run Server with 7 drives and dual Xeon processors. Heat has not been a problem for me. Runs warm but considering it’s 1200watts, it’s average on the cooler side.

Runs a 5090 without spending a fortune. Seasonic quality.
As expected from Seasonic it works perfectly and has plenty of cables. The were nice enough to send me the updated power cable for my 5090 for the cost of shipping despite being past the 90 day cutoff from day of purchase. It hasn't melted yet after a couple months of gaming. Power supply is quiet and I don't notice it. As it should be.

In love with seasonic
Never been disappointed. After replacing the power supplies in my computer room from junk brands to seasonic, the waste heat went down immediately. I didn't really notice until the next summer, but clearly quality PSUs are worth. I've only had a single seasonic PSU fail of the ~8 or so I purchased and they RMAd it and have no issues with the replacement. Happy customer.

Seasonic Vertex GX-1000-1000W
Solid , heavy construction , 10 yr warranty . Seasonic is the premium of all power supplies When I buy a power supply I never skimp on quality , and I buy way over what I need . any PSU will only put out what is needed so If the system is needing 700w and its a 1000w psu ot will only put out 700w and run cooler then a psu that has to work at 100% and run hot and stress it out and shorten its life. I like the braided cables , each wire individually wrapped , but still flexible . The only con is that their is no 4 pin CPU cable , just 2 8 pin cables and their made as one unit so no way to put them in a 4 pin motherboard connector

Exceptional
I've typically used Corsair RM gold series for custom PC builds and upgraded the cables. The performance has always been very good, never a problem but more recently I ordered a Corsair RM 1000x and received a used unit, that reeked and appeared of poor quality. It was returned along with the CableMod upgrade cables, after which I ordered the Seasonic Vertex and what a difference between good and exceptional. The Vertex is super quiet, has a small footprint and comes with premium cables. There's no need to upgrade the cables, the one's that come with the Vertex are easy to work with and look nice. Great PSU!

Everyone said they were great... instead I found out they don't fully back their own product
After hearing amazing things about this company and its products from all my friends and a bunch of YouTube reviews, I bit the bullet and tried them out; but that turned out to be a waste of money. This product started having fan issues (the fan started clicking) after about 6 months of use... What's worse is that the company requires YOU to spend extra money to send THEM back THEIR defective product. I won't even get into their "advanced replacement" which requires you to PayPal them money... Which sounds super sketch... I will not be buying from the company again - back to Corsair I go.

Handles almost anything
This PSU has handled a couple of power surges and not given me any issues. It's plenty of power for my Ryzen 9 7950X3D and 4070ti Super.
