2 out of 5 eggsWhere is my REBATE???

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Cons: n/a

Hi Youris N., I am sorry you did not yet receive your NewEgg rebate but this review is for the product, the power supply and if you have an issue for a NewEgg rebate, please kindly contact NewEgg about this matter. Thank you for purchasing Seasonic.

3 out of 5 eggsGood... But noisy

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Powers everything nicely and efficiently. Cables are nice and flat. It's 80 Plus Platinum. Hybrid fan option is great

Cons: The first week with this PSU was flawless. After that however, I noticed it making a strange noise.

Assuming it just coil whine, it sounds similar to a mechanical drive reading or writing something. It would only start to make this noise after running for about an hour. I tested different loads on the PSU, but the noise always remained constant. It's not a loud sound, but it is very annoying.

Other Thoughts: The only reason I bought this PSU was to compliment my silent build.. but this ruins it :(

Im a little hesitant to RMA because I'm not sure if they will consider it :(

overall good power supply, but I am a little disappointed in the unit I received.

Manufacturer Response:

Hi David,
Please send a message to: newegg@seasonicusa.com and we will try to sort this out for you. Thank you.

5 out of 5 eggsAwesome !!

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Looks great, feels solid. Modular !! Best of the best !!

Cons: Nothing yet.

Other Thoughts: What can I say, it works. Only used half of the cables so wire management was pretty easy. Plenty of juice on the 12 V rail so bring on the graphic cards !!

1 out of 5 eggsLasted 24 hours

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Seemed pretty quiet while it lasted!

Cons: Waited a month or so for a special project. Built the computer (digital music client) on Saturday, no graphics card, i7G4, 3 SSDs, no optical or mechanical drives - so hardly a big load. Worked all day Sunday. Dead on Monday morning. Spoiled a run of 3 or 4 good Seasonic ones, time to try something else. Have a SuperFlower Golden Silent coming tomorrow.

Other Thoughts: I'll follow-up with comments on their customer care once I have gone through RMA process.

Manufacturer Response:

Hi Chrstopher, Sorry you have had this issue. Can I ask that you check to make sure all the DC cables are connected properly and are seated properly into the sockets. If you have any questions or concerns, please contact us at newegg@seasonicus.com Thank you.

5 out of 5 eggsCoil Whine Begone! - Instructions inside -

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Comes with an awesome Crown Royal-esque bag. Modular. Visibly superior build quality. Plenty of power, no inflated specs. I'm running an AMD FX-8320 overclocked to 4.7GHz, 32GB RAM, dual ATI HD7870 Sapphire GPUs, 5 hard drives, 1 SSD, six 120mm fans, one 140mm fan, one 200mm fan, and one 230mm fan. PSU generates almost no heat. Quiet, with the option of running it fanless. Amazing price (on sale)
No coil whine (See other thoughts)

Cons: Expensive (if not on sale)
Coil whine at first (see other thoughts)

Other Thoughts: My old system started producing coil whine when I upgraded the FX-6350 to a 8320. Gigabyte GA-970A-DS3 with a Corsair TX-650 PSU. Upgraded to ASUS M5A990FX PRO R2.0 with this Seasonic 660XP2 and it still produced coil whine. I was quite distraught, until one day I took the system out to the garage because it was around 10 degrees outside that night and the cold garage was a perfect place to do some overclock testing. Plugged it in, powered it on, ZERO coil whine. Took it back inside, coil whine returned. It was the UPS. The one in my office was an older APC, while the newer APC that the servers were on in my garage actively filtered the power, rather than just kicking on when there was an outage.
So to anybody having coil whine problems with this PSU, try testing on a different UPS. Possibly one with AVR. I know I installed an identical PSU in another server I maintain, and it produced zero coil whine when plugged into a CyberPower Pure Sinewave UPS. This is a premium PSU and seems to require clean power to function properly, kind of how you wouldn't put regular unleaded gasoline in a Ferrari.

5 out of 5 eggsOne Of The Best Power Supplies Out There

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Quality Seasonic Brand
Top-rated Power Supply
80 Plus Platinum Certified (For Super High Efficiency)
Fully Modular Design
Awesome 7 Year Limited Warranty On Parts & Labor
Nice Looking Product
Even The Packaging Is Very Well Done

Cons: None at all!

Other Thoughts: Seasonic makes some of the best, if not THE best power supplies on the market. Many system builders choose Seasonic to power their systems - myself included. This power supply has great reviews across the web and is highly recommend.

If you're building a new system or simply need to replace an old power supply, go with a quality power supply from Seasonic. Don't put your system at risk by going with a cheap no name brand power supply. The power supply is the most important component of your computer. It provides the needed power to run your system. Never skimp on your power supply!

If you're building a new system, best wishes to you and have fun building it!

4 out of 5 eggsLove-hate Relationship

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: I have it for months. It works great. While I didn't measure it, one of the reasons I bought it because of its 80+ platinum rating. The modular wiring, plenty of connections, high wattage and quite reasonable price don't hurt, either.

Cons: I noticed the whirling sound after reading about it so it's not really that pronounced. My wife didn't notice it until months later - I built the PC for her. It still doesn't bother her, but I found it annoying.

Other Thoughts: Would I still buy it knowing ahead of time about the whirling sound? Yeah, the pros outweighs the cons a lot. Just make sure you don't use it in a home theater. Gaming's OK.

5 out of 5 eggsSeasonic SS-660 Excellent

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Efficient, cool, quiet. Cables long enough for my Antec P180 series case, PSU sits on the bottom. Cables are flat, which fit inside my case really well better, than the 860 watt version which had sleeved round cables. And, I have had NO coil whine. I have a temperature sensor near the psu and the temperatures are in the teens to low twenties centigrade.

Cons: NONE

5 out of 5 eggsExcellent PSU

This review is from: Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Modular.
Hybrid cooling.
No noise at all.

Cons: See Other Thoughts, below.

Other Thoughts: There are only two things I don't like about this item, and neither has anything to do with the PSU itself.

The first is that I would love to see Seasonic use something more custom for their cables. As they are now, they are flat and sometimes difficult to route.

The second this is that I would love to see them include a better case sticker. The tiny one they have now is not good enough to display.

Otherwise, this is a 1st-class PSU and the 3rd one I have used for other builds.

Manufacturer Response:

Thank you for your review. The issue of cable type is always difficult and we are working to make improvements and as well... the case sticker! Thank you for your support!
