5 out of 5 eggs

This review is from: SeaSonic SS-520FL2 520W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: The PSU is everything advertised. It’s fan-less so there’s no noise or buzzing. The cables are longer than those found on generic PSUs so they work well in a large case. This 520W PSU replaced my generic 450W PSU which was about a third of the weight but only 70W difference. The quality is easy to see when it’s in your hands.

Cons: Price

5 out of 5 eggsGreat PSU

This review is from: SeaSonic SS-520FL2 520W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Quality is amazing!!! I bought two of these PSUs and both run like a champ, 24/7 since I got them. I do love knowing there is no fan adding vibrations. I also love that it is fully modular which helps with the cable clutter. The real seller for me was the 80 Plus Platinum rating. I did my homework on these units, and they rated up there by many reviewers as one of the most efficient PSUs in its price range. Not to mention, its fanless, and fully modular. The choice was a no brainer for me. They generate no noticeable amount of heat when putting my hand above it. To be fair though, I am not putting more then 120Watts of load on it. Maybe I need to buy a video card and start bit-mining. =] The included accessories are a nice touch.

Cons: I got nothing!

Other Thoughts: I would buy these all day, everyday!

3 out of 5 eggsGood supply, but not really silent

This review is from: SeaSonic SS-520FL2 520W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Very well packaged. Exceeded my expectations for quality by a wide margin. Really well made. Very quiet and not audible from about 2 feet away. Closer and you can hear a low buzzing sound.

Cons: Low buzzing sound if you are close to the unit. It is not silent. My Noiseblocker 700 rpm fans emit about the same level of noise as this supply.

5 out of 5 eggsbest power supply period

This review is from: SeaSonic SS-520FL2 520W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: completely silent, no high pitch wine, no nothing. using with new haswell system.
finally able to run 1600mhz memory stable with this power supply. it ran but with errors before with any of my old power supplies including 3 of my older pc power and cooling 950w power supplies would not run 1600mhz memory stable

Cons: as with anything good price. but you get what you pay for.

Other Thoughts: i built 2 new haswell systems with top of the line corsair dominator 1600mhz memory at 78824 spd and 2100mhz memory. could not get it to run stable no matter what, sometimes it would last for a week or 2 then crash or long waits just for internet explorer or freez up or problem with onboard graphics wile playing games and i thought it was the cooling. went thru a few coolers trying to fix.

i have a few older top of the line power supplies and some cheep ones even a 1500w and 1600w power supplies

i could not get these new computers to be stable for more then a week at a time. then decided on this seasonic silent power supply.

holly cow batman stability is this power supplies middle name.

anyway now buying another for the other computer . i got the first one from amazn cause it was cheaper and free 2 day shipping with prime. now there the same price so may buy from new egg have promo code for 10% off still winds up being just $7 cheaper since i have amazn prime and 2 day free shipping and worry free returns, free return label, No questions asked. i been with newegg since it opened and because of neweggs best customer service and good prices

5 out of 5 eggsBest fanless PSU out there

This review is from: SeaSonic SS-520FL2 520W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Looks awesome
Fully modular
Plenty of power for pretty much any single GPU system
Platinum efficiency
Top quality construction/components
Fanless for complete silence
7 year warranty

Cons: A little expensive, but you get what you pay for

Other Thoughts: I've been using Seasonic's platinum fanless PSUs in all my single GPU or no-GPU rigs for a while now, and they're just awesome.

Every other component in your rig depends on your power supply, and if you don't need 600+ Watts of power (very few single GPU rigs do), then this is the perfect power supply for you!

5 out of 5 eggsQuiet (520W)

This review is from: SeaSonic SS-520FL2 520W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Absolutely quiet. I did not hear any of the high-pitch (or low-pitch) whines that some posts were indicating.

Cons: The included cables are quite stiff. They are also long for an m-ITX case (would be a pro for ATX build). The SATA power plugs are quite thick at the base, and with the stiff cables it can be a problem in certain situtation (like in my build).

Other Thoughts: First time building an m-ITX rig, and while the efficiency and quietness in this PSU helps, its long and stiff cables do pose great challenges along the way. The biggest con is definitely the thick SATA power plug. I compared to my old rig's (from a Cooler Master 500W) and that one's SATA power plug is much thinner, probably more in line with what most designs are. While one SATA power cable provided does contain 4 SATA power plugs, the cable is so stiff that it is quite an acrobatic move to connect these to devices. Not enough to take one egg away, but it's a hassle.

Otherwise regarding noise, since this unit does not have the whines that others are talking about, it is absolute quietness.

5 out of 5 eggsThe Audio Question...

This review is from: SeaSonic SS-520FL2 520W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: 1. Silent. If you record with a PC in the same room as the mic, this is the PSU for you.
2. 13mV ripple on the 12 volt rail is unheard of. What that means is low noise and clean efficient power which prolongs the life of your computer. This is an important aspect of a build that is often overlooked.
3. The 100% modular cables are nice, a little stiff, but I like them because they hold the shape you bend them to.
4. Small. I had room to install the case fan on the bottom next to the PSU and my GPU loves it.
5. There is no high pitched coil whine or any other sound coming from it, as I have read in other reviews.

Cons: There are no cons.

Other Thoughts: As soon as I turned the audio from the computer on, I could hear an instant difference. Better definition, programs run super stable. I hope they come out with a 650W down the road to power 2 GPU's.
