    • Power that is worth the investment!
Style: Vertex Gold 850W
I am by no means tech or PC savvy. My first gaming PC was built using iBUYPOWER and since then I have replaced parts and upgraded, on a plug-and-play basis. The PSU was the most recent. I had almost the same exact model in my PC, except it was a 650. I upgraded my GPU, installed a disc drive and faster RAM. My PC had also not been operating the best and everything I had read suggested I begin by replacing the PSU. I would like to say this replacement combined with updating the BIOS was my overall success (for those who might be getting BSOD or random black screen while the PC is fully powered up - related to possible Kernel-Power Event ID 41 - start with your PSU and BIOS!) The 850 will have more than enough power to handle any of those CPU/GPU/RAM or any other upgrades you are looking to put in. I have an RTX 2060 Super, and it handles it no problem (it also says it is rated for 3/4K series). Overall, installation is self-explanatory, and the process is plug and play. I recommend you give yourself plenty of time, space and patience and read over all the literature included in the box. The box comes with plenty of new cables which again, the instructions recommend be replaced. With the cables are also Velcro ties and zip ties to promote neater wire management. Overall, I recommend Seagate products. This is my second PSU (the first one was purchased in 2019, and I replaced it the end of 2024) - depending on how frequently you game and the load you put on your PC, this in general is the life expectancy for a PSU. Great value for the power you will get out of it and rest assured, you can trust Seagate. They make durable and reliable products! ... show more

    • Silent and Reliable Power for High-End GPUs
Style: Focus Gold 1000W Black
Extremely quiet and delivers more than enough power for my RTX 5070 Ti OC setup. Solid build quality and stable performance make it a reliable choice for any high-end gaming PC.

    • Exactly what you get and well worth it!
Style: Vertex Gold 1200W
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. ... show more

    • Well made power supply!
Style: Vertex Gold 850W
Excellent power supply. Quality cables and good connectors. Quiet and powerful enough for AM5 systems with a 5800X processor (fairly power hungry when OC), multiple fans, several drives, and a 9070xt Red Devil OC.

    • Solid PSU
Style: Focus Gold 1000W White
Simple plug and play, connects effortlessly. Cables are compact, are super easy to maneuver around, come with zip ties already on the cables. Great psu, functions as it should.

    • Very great PSU.
Style: Vertex Gold 1000W
Very quite operation. Not getting any extra noise from fans. Very high quality psu. I am quite impressed at the price I paid. Would absolutely recommend. Very modular. There is definite a reason so many like this Seasonic these days.

    • White PSU and cables for a good price
Style: Focus Gold 750W White
The unit has been functioning very well so far and running pretty quiet. The all white cables were a big draw and they look pretty good in the all white system. The modularity is very appreciated, although in smaller cases the cables might be too long, depending on where you need to route them.

    • Burnt plastic smell [1000w]
Style: Vertex Platinum 1000W
I too am getting the unsettling burnt smell / offgassing from this power supply, now several days into use. This was an upgrade to an existing system, replacing a 5-year old Seasonic so it's for sure the unit. Not really worried about safety or fire, but this is unacceptable smelling, and has been hurting my eyes - hoping for better luck with a replacement. Update: 2nd unit also smelled bad, trying a different brand. ... show more
