Easy Installation and Fully Modular

Pros: -Cheapest Fully Modular PSU from a reputable brand
-Decent efficiency
-Clean black cables
-Fast delivery

Cons: - Only 80+ Bronze, I would have hoped for Gold

Other Thoughts: SeaSonic is a great brand and highly trusted in the PC community definitely would buy from them again but I may spring for a higher efficiency rating

Really quiet with good performance

Pros: Modular design keeps wires to a minimum allowing for a cleaner case. Fan speed based on load makes for a very guiet operation.

Cons: Modular cables took some inspection to determine which one was for extra power connection on motherboard. Some connectors are very similar.

Other Thoughts: Would recommend this for any mid level build requiring less than 600 watts.

So far so good

Pros: - modular system helped me get rid of the spaghetti monster in my case
- very quiet
- great deal with rebate

Cons: - manual could be a bit better
- some of the connections were a bit hard to make due to cable stiffness

Other Thoughts: I bought this to replace my aging Thermaltake Smart 750W PSU which was getting noisy. I didn't realize how noisy it was really until I got this. Even when it was working well the Thermaltake had audible fan noise. This unit is silent. It was a little confusing getting the main connector cable in place and the documentation is pretty scarce, but you figure it out pretty quick. I have not had this product long so I can't comment on its longevity. However Seasonic has a great reputation so I'm crossing my fingers and giving a good recommendation.

working as it should

Pros: great price
full modular
quiet
comes with bag to store any cables you dont use

Cons: none for the price

Other Thoughts: thought i would leave a review since most of the recent ones have been negative. i got this to replace a old 700w Thermaltake TR2 that was starting to get very noisy. very happy with my purchase and for a price of 39.99 after rebate, great value and deal.

i am running this to power a i7 3770k OC'd to 4.2ghz with 16gb of ddr ram and a GTX 1060 6gb.

EDIT on 3/16/19
Power Supply still running strong. 3770k OC has increased to 4.4, added a 1080TI to replace the 1060, increased RAM from 16gb 1600mhz to 16gb 2400mhz and added 2 SSDs. Still zero issues with this power supply and I highly recommend it.
