This review is from: SeaSonic SSP-550RT 550W ATX12V v2.31,EPS12V v2.92 80Plus Gold Certified Active PFC Power Supply -- OEM

Pros: -Runs like a charm. Everything is being powered up as needed and supporting my GPU that demands 500W just fine (Sapphire Radeon HD 7950).

-The silence. Makes me double check if I really did power up my computer.

-80 Plus Gold certified assurance

Cons: Just a few nitpicks:

-The plugs might be a bit snug. It requires a bit of pressure to push it into my hard drive and CD drive.

-I thought it would have an individual box that it would arrive in like how you would buy a PSU from an electronics store. I opened up my Newegg shipping box to find that it was encased in a lot of bubble wrap and the wires were strapped down with tape to the PSU. It made me think that this was a refurbished product.

Other Thoughts: The size is just right for my Dell XPS 8300. I've only had it for a few days now as compared to my old Dell PSU that has been powering it up for the past 3 years. Only reason why I had to swap out was because I got the HD 7950 and it requires at least 500W to work.
