5 out of 5 eggsA Rare, Perfect Product

This review is from: SeaSonic Platinum Series SS-400FL2 Active PFC F3 400W ATX12V Fanless 80 PLUS Platinum Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: -Completely silent
-Runs very cool
-Not overly big
-Astounding, consistent, quality power
-Fully modular
-7 Year Warranty!
-Platinum efficiency
-Velvet bag

Cons: -Nada

Other Thoughts: It's the rare perfect product. If you bought this power supply, at probably a premium, then you already know that SeaSonic are known for producing among the best - if not the best - power supplies in the world. Not much else to say. Every independent reviewer is amazed by the quality.

I debated adding this as a "Con", but you must be aware of the mounting restrictions imposed by SeaSonic: it must be mounted in only one orientation, effectively "face up".

There are a fair number of cases where the fan grill would be pointed downward, and thus these fanless models would not be good candidates.

5 out of 5 eggs

This review is from: SeaSonic Platinum Series SS-400FL2 Active PFC F3 400W ATX12V Fanless 80 PLUS Platinum Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Very quiet (obviously) but I also do not here any type of hum or other sound from it

Cons: I particularly do not like the SATA cables, which would be fine for vertically stack disk...but not so much for horizontal placements. Not enough to crack an egg though.

5 out of 5 eggsPerfect for HTPC

This review is from: SeaSonic Platinum Series SS-400FL2 Active PFC F3 400W ATX12V Fanless 80 PLUS Platinum Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Completely silent and very cool.

Cons: None

Other Thoughts: This runs my Haswell based HTPC in a LianLi PC-C50 case with a 5 disk setup, two SSD and 3x 7200rpm drives and 4 120mm fans along with the InfinitTV 6. Plenty of power available for this setup making it the perfect PS for HTPC.

3 out of 5 eggsNinja quiet until it died

This review is from: SeaSonic Platinum Series SS-400FL2 Active PFC F3 400W ATX12V Fanless 80 PLUS Platinum Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Great packing materials, worked exactly as advertised for 3 months of very light duty. Perfectly quiet and well built. I really liked it and would have given it 5 eggs if it hadn't died so very quickly.

Cons: Died with a loud "Pop!" after a little more than 3 months of very light duty (used mostly on weekends). I expected better of such a premium unit, but the 7 year warranty will help. Just hope the next one doesn't die after a few months.

Manufacturer Response:

Hi Robert, we are very sorry for the inconvenience this has caused you. Please visit www.seasonicusa.com and please start the RMA process and they will take care of your issue as soon as possible. Thank you.

5 out of 5 eggsSilent very efficient power supply

This review is from: SeaSonic Platinum Series SS-400FL2 Active PFC F3 400W ATX12V Fanless 80 PLUS Platinum Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: I'm using this power supply to power my home server which consist of a i7-860 processor with 8gB of ram, 4 4tb wd red drives for the main raid array and 2 4tb backup drives.

With all of these compoents I'm still averaging around 40-45 mB when I'm not stressing the system. This is down from around 55-60 with my older corsair bronze certified power supply!

Cons: None
