3 out of 5 eggs$20 Replacement

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: I was excited to get and install my new Seasonic 520w Fan-less Power Supply with a 7yr warranty. I did a lot of research and this was THE one to get. All the reviews were great and the warranty spoke volumes. Overall first impressions were great, the design was beautiful everything was as to be expected and the install went off without a hitch.

Cons: About the third day after installation I woke up and attempted to turn my machine on. The moment I pressed the power button there was a very loud "POP" and my machine no longer showed any signs of life. I pulled the new PSU out and replaced it with the old one I had saved and my machine fired right back up. I returned to the website to find the steps I needed to take in order to get a replacement. Got my RMA and ordered my return shipping label only to find out it would cost me $20 to return it. Needless to say I am disappointed that such a distinguished company charges customers (within 30 days even) though it was no fault of their own...

Other Thoughts: I got the replacement in a timely manner and it is currently installed. I just hope this one lasts longer than 3 days because I cannot afford another $20 replacement fee.

2 out of 5 eggsMuch Coil Whine

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: Without pros when a fanless PS comes in this noisy. Coil whine that fills a room. To be fair, open TJ7 case.

Cons: The new SS-520FL2 came in almost as noisy as the same 2 yr. old model it replaced. The latter, initially fairly silent, became increasingly noisy as time passed, and unbearably noisy after a recent first overclock. All bios power saving enabled.

Other Thoughts: Is Seasonic merely careless in putting out noisy PS. Or, is New Egg merely recycling RMA'd noisy models? Either way, I hold Seasonic responsible. They know there's a problem, and apparently do nothing. lRMA'd for Rosewill Silent Night.

5 out of 5 eggsOutstanding

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: Silent, including no coil whine. Stays cool with proper ventilation. Extremely efficient. Built to last.

Cons: None whatsoever. Worth the price.

Other Thoughts: Has worked flawlessly for 18 months powering a system drawing about 375 watts. First used in a Silverstone TJ-08, and now packed into a Cooler Master Elite 110. Both place the PSU at the top, with ventilation to the outside. Putting my hand over the grill, I have never felt this Seasonic unit get warm, even during stress testing.

Odd to say about a PSU, but this thing exudes so much quality I wish I could show it off with a case window.

5 out of 5 eggsQuiet, Stable

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 high efficiency, borders on "Titanium" certification which is brutally hard to do off 115V

Dead silent

Built like a tank

Very good voltage regulation

VERY high quality parts

7 year warranty.

Seasonic is (arguably) the best power supply OEM in the world (Superflower makes a darn nice product as well)

Have used a ton of Seasonics over the years, always well designed and well built.

Cons: It's pricey for a 520 watt power supply, but that is mostly because it's really about an 800 watt unit de rated to be stable at a lower power level.

Comes in a velvet pouch?

Other Thoughts: The Silverstone Nightjar is, give or take a paint job and a little packaging, exactly the same power supply

Must have open ventilation above the PS or it will fry it's self.

There is an old saying "If this is the sort of thing you like, you will like this thing rather a lot"

If you want a bulletproof silent power supply with ultra high efficiency, this is it.

If this is what you need and are willing to pay the price, it is the best example of what it is.

2 out of 5 eggsGreat except for the buzz

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: It functions like it's supposed to. No power issues at all.

Cons: Buzzing. None at first, and then I thought it was just a bad fan somewhere, but when I went to fix it found it was from the power supply. And it varies, sometimes it will be absolutely quiet, other times it's like a constant crackling. Seems worse as it warms up or if the room is warm.

Other Thoughts: If it wasn't for the buzzing I would give it five stars. It seems to be hit or miss based on other reviews; I guess I got a bad one.

Manufacturer Response:

Hi Randy, I am sorry about the noise issue. Can you please make sure all your energy saving modes in the BIOS are enabled. This should resolve your issue. If not, please contact us at newegg@seasonicus.com Thank you.

4 out of 5 eggsReally good quality.

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 efficient and well built PSU.
-No coil whine as mentioned by other reviewers.
-No noise emitting from my unit whatsoever.
-Powers a mini-ITX i7-4770, 16GB RAM and a GTX 980 with ease.

Cons: -Supplied PSU cables are a bit stiff but manageable.
-I'm not sure if was just my unit but it did not come with an AC power cable, which is mind blowing for a PSU of this cost and quality.

5 out of 5 eggsAwesome

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: Excellent build quality. Nicest psu I've ever had, and well worth the little bit extra in price compared to getting a psu that just does the job. Packaging was over the top, but in a good way, and I still can't believe the weight difference compared to my cheap 750 watt unit. This thing is heavy and feels solid. Also, the cables are all black including the 24 pin which is done very nice.

Cons: None so far.

Other Thoughts: I'm sold on the SeaSonic brand, and quality you get with this name. Can't believe I waited so long to give it a try. Also, platinum rated, fan-less psu's are amazing, idk if I already mentioned that.

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!
