Review: 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.
Review: 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
*by G***S on December 23, 2025*

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.
