5 out of 5 eggsUpdate to previous review

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: + Silent

Cons: - Support model code be a little cleared

Other Thoughts: This is an update to my previous review: http://www.newegg.com/Product/SingleProductReview.aspx?ReviewID=4252985

Last week, I got the server working with the power supply that I thought was faulty. It turns out the reboots may be related to the sata power cable. Cable is completely plugged into PSU but straightening or bending the wire near the PSU connector either allowed the PC to boot, not even turn on, or turn on and get stuck in reboot cycle. Adjusting the wire while in a reboot cycle will end the reboot cycle and allow pc to run. Server has been running for a few days without a reboot.

Will continue to monitor over the next few weeks and see if I can get a replacement cable.

Support is there. Just wish they could be more responsive. Looks like I will keep a spare PSU in case I have problems with a critical machine.

5 out of 5 eggsIt works

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: Rebate paid with no hassle! (rare these days)
I like the fully modular style, as it minimizes the cable mess. There is also a good selection of cables for whatever components are in use.
I have not tried the hybrid mode which keeps the fan off until needed, but the regular mode is inaudible. Having a near silent case, even when gaming is awesome.

My 2500K/GTX970 system uses about 20W less when gaming, and 8w less when idle compared to before, with an older 80+ bronze supply. The elecrical savings aren't significant, but my airflow is much better with the Seasonic's cables.

Cons: None that I have found.

Other Thoughts: I am happy that Seasonic pays their rebates. Others which don't pay, do not get repeat business.

2 out of 5 eggsDied within 10 months and no response from Seasonic

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: + Quiet

Cons: - Support is non-existant

Other Thoughts: Purchased for use in my new Xeon 1230 v3 in Apr 2014. Server randomly rebooted from time to time so UPS was added. Problem went away and reboots became a rarity.

Back in Jan, server began rebooting randomly. Problem worsened to the point that the only "fix" was to turn off the machine and then flip the PSU power switch off & on. By end of Jan, machine would reboot continuously and fix did not work anymore so I turned it off. A week later, machine would not even turn on even though the motherboard got power (lights turned on and ethernet port lights would blink). Plugged up a lower wattage PSU and machine booted just fine and ran without a reboot for about a day. Tried this PSU again but machine would not boot.

Contacted Seasonic USA support via phone (left messges) and sent emails 3 weeks ago and still do not have a response or anything acknowledging they got my support issue. I would buy a Corsair but Seasonic is an OEM for them as well. Really a shame as I primarily bough Seasonic PSUs for my machines. Really disappointed by the lack of support and responsiveness.

Manufacturer Response:

HI Charles, I do apologize for the inconvenience both the faliure of the unit and the lack of response has caused you. Please note, the best wasy to proceed with RMA is to visit our site at www.seasonicusa.com and there you can do the RMA directly. Please note, calling Sea Sonic office will only direct you to the web RMA processing and there is very little tech support we can provide over the phone. Please let me know to which e-mail did you write to where you did not have a response. Perhaps it ended up in the SPAM folder, we will need to control this. Please write to us at: newegg@seasonicus.com and we will respond within 36 hours. Thank you.

5 out of 5 eggsAmazing

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: 80+ Platinum
One of the best, if not the best, OEM out there.
Great deal at the time
Protects your gear well

Cons: If you have a catastrophic failure, it might be hard to find it.

Other Thoughts: I'm driving an i7-5820k and 2x gtx 980's with this. Since I was dropping close to $2000 on a new build, I decided not to skimp on the non-sexy parts. I will never go back to any other OEM except possibly FSP. The efficiency, silence, and safety are a true cut above the rest. If I decide to bios mod my 980's to go further outside their TDP limit or go for a more robust water cooling setup, I'll just update to a larger Seasonic.

2 out of 5 eggsOut of luck after 18 months

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: Great unit when it's working

Cons: Not great when it dies before the warranty expires and you can't get a working replacement

Other Thoughts: RMA'ed first unit, got back a dead unit. Emailed support, no response. They recommended shipping it back in the original box for protection, I get it back in a UPS envelope.

Manufacturer Response:

Hi Quinn, please write to newegg@seasonicus.com and please let me know your RMA number and I can trace and see what happened and try to resolve your issue satisfactorily. As well, to which e-mail address did you write to of which there was no response? The recommendation is to use the original carton but of course, if this is not possible, any carton will do provided it give sufficient protection to the power supply during transport. Thank you.

2 out of 5 eggsAnnoying Buzzing Sound

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: Great price for 80+ Platinum fully modular PSU (when on sale), only paid $70 after mail-in rebate. Hybrid mode is nice, never had the fan turn on while it was enabled. The included cables are high quality and the included bag for them is a nice bonus.

Cons: The constant high pitched buzzing sound is very annoying, even more so with my unusual case where the PSU mounts in the front. Sadly, this totally ruins an otherwise flawless product.

Manufacturer Response:

hi, thank you for you review. In reference to the noise, please make sure you have enabled all energy savings modes in the BIOS as this should resolve your issues. If not, then please contact us and we will try our best to sort this out for you. Please either write to: newegg@seasonicus.com or visit www.seasonicusa.com for RMA support. Thank You.

5 out of 5 eggsWorking Great

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: No problems for almost 2 years

Cons: It has a fan and when the load increases the fan speeds up. It's usually quiet because I don't play games or do much that load stresses the computer.

4 out of 5 eggsOverpriced, Wrong Dimensions

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 Components
Platinum Rating
Quiet Fan
Switch for fanless mode

Cons: 1. Dimensions pictured are wrong, which required substantial case mods. It is not 5.91" from front to back as illustrated, rather 6.3".

2. Velvet Bag - Waste of money. Why do you need a fancy bag for something you install once and never take around by itself anywhere? This unnecessarily adds to the cost of an already expensive model, for something of no use.

3. Poor cables - The cables and connectors are very rigid, expected better from this premium model. It made for a very difficult install in a small case. Need more diversity in the cables included, many duplicates were included but no variety. For instance 4 long PCIe cables were included, few people need cables two feet long which clutter and clog airflow. The flat cables are horrible and do not lend themselves to compact or efficient builds.

4. Strange huge cable bag - Also a waste of money. It's a strange design that is two pockets that fold so you can velcro them together, for no apparent purpose. Again, once installed there is no point to this bag. Only a small bag would be desired to hold extra cables, but this is huge and will hold every single cable. Why would you need a bag that holds ever single cable after install? A cheap Rosewill PSU I bought has a simple small cloth bag for leftovers which is more practical, and cheaper.

5. Overpriced - I was reluctant to pay this much but a PSU has a long usability life. I could have gotten a PSU 80% the quality for less than half the price. You definitely pay a premium, the elaborate bags don't help keep the cost down. This PSU cost more than any other component in my build, besides the CPU and GPU.

Manufacturer Response:

Hi James, thank you for your review and sorry for any inconvenience.
Please note:
1. The dimenstion is written as L 160 x W 150 x H 86 and this is correct. Perhaps we should have more clearly specified the L = Depth @ 160mm.
2. The cables are fairly stiff, especially if delviered in the winter time. The best solution is to use a hair dryer and carefully warm up the cables for easier system build. We must use a certain thickness of copper wire and this, together with the required plastic shielding thickness, adds to the stiffness of the cables.
2. As for the velvet & cable bags, when purchased in very large volumes, the cost is not very high. We did receive many positive and negative feedbacks over these bags and our PM will take all comments into consideration.
Thank you and if you have any concerns or questions, please write to newegg@seasonicus.com

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: Can't hear it and its on the standard fan setting in a case that is not meant to be quiet. Seasonic rocks in case you guys haven't done your research.

Cons: Pretty tight connectors. Felt like I was going to break my motherboard plugging it in...
