SeaSonic PLATINUM 1050W Modular Power Supply

Introduction

SS-1050XP3

Ultra Tight Voltage Regulation
Improved load voltage regulation keeps the voltage fluctuations on the 12V output within +2% and 0% (no negative tolerance), and on the 3.3V and 5V outputs between +1% and -1%, which (under 80 Plus load conditions) results in smooth and stable operation.


SS-1050XP3

Seasonic Hybrid Silent Fan Control - S²FC & S³FC*
The industry first, advanced three-phased thermal control balances between silence and cooling. The Hybrid Silent Fan Control provides three operational stages: Fanless, Silent, and Cooling Mode. In addition, there is a switch provided to allow for manual selection between the Seasonic S²FC (fan control without Fanless Mode) and the S³FC (fan control including Fanless Mode).

SS-1050XP3

New feature - Hysteresis - is achieved by a fan control IC, which optimizes how frequently the fan switches on and off. At 77°F (25°C) ambient temperature the fan turns on when the load rises above 35% (±5%) and it turns off when the load drops below 25% (±5%). Due to this lag in response the fan switches on and off less frequently, which reduces power loss in Fanless and Silent Mode.

SS-1050XP3

Dual Copper Bars
These pure copper bars conduct high current more efficiently to reduce impedance and minimize voltage drop.

SS-1050XP3

80+ Platinum
The Platinum Series, certified in accordance to the 80PLUS highest standards, offers the newest technology and innovation for performance and energy savings with up to 92% efficiency and a true power factor of greater than 0.9PF.

5 out of 5 eggsI love it!

Pros: Modular, fanless mode, quiet.

Cons: Length? But most kilowatt PSUs are long.

Other Thoughts: Bought it for the hybrid fanless mode, which works great!

It's silent like the rest of my machine's fans until I start gaming, but by then my speakers drown it out.


I've been using SeaSonic PSUs for years, and I've never had a bad experience with one.

4 out of 5 eggsUpdated Review - Power Socket Issue

Pros: Nice Layout, Fully Modular

Cons: None - With the replacement unit

Other Thoughts: This is an update to my review from 3/21/2015.

I returned the malfunctioning PSU for a refund and placed an order for the same model PSU for the sake of speed. I swapped the PSU, but I used the cables I had already installed in the case that came with the malfunctioning PSU (including the AC Cord). After installation, I made sure the AC socket did not exhibit the same problem. It's been about six weeks and I have not had any issues.

5 out of 5 eggsGreat PSU

Pros: My friend recommended this PSU. I ordered this PSU two weeks ago and the unit arrived in perfect condition. Quiet, fully modular and high quality. Love the hybrid silent fan control design.

Cons: None so far

Other Thoughts: I have some questions about this PSU. I called Seasonic and they patiently answered my all questions. Great customer service!

1 out of 5 eggsPower Socket Issue

Pros: Nice Layout, Fully Modular

Cons: I have the exact same issue as Thomas D. (review from 1/22/2015). The system shut down. While examining the system, I made sure that the power cable was properly seated. When I touched the power cable near the socket on the PSU, it made an electronic crackling sound. When I adjusted the cable, the system would briefly energize. I tried different power cords with the same result.

Other Thoughts: I requested a refund RMA and ordered a new PSU of the exact same model. I really do not want to rip the wires out of the case, and I'm hoping the new PSU does not have the same problem. I will update the review after I install the new PSU and after a proper burn-in period.

Manufacturer Response:

Hi Darrel, I am sorry for the inconvenience. This issue sounds like a faulty AC Cord and not necessarily the socket itself. If you have any questions or concerns, please contact us at newegg@seasonicus.com Thank You

5 out of 5 eggsheavy beast

Pros: this replaced a noisy TX850 from corsair that kept triggering power surge sensors on the motherboard and restarting the system.

my overclocks have seen increases that would have shut down the other power supply. stability is really underrated and this unit provides it. im not a PSU expert or electrical engineer but the thick and clean insides and the sheer weight of this unit compared to my previous psu is very apparent. my graphics card is louder than this unit. modular layout means minimal amount of cabling, looks neat and simple

Cons: price. i bought this while it was on a huge discount

Other Thoughts: i dont know why people are buying so much channelwell rebranded garbage

5 out of 5 eggsThe best PS? - maybe

Pros: One of the critical components in any electronics is having a stable, clean power supply. This one is very well built, and in my initial looking is very clean and stable. The power supply comes with high quality cables - and lots of them.

When you first un-package this device, you feel like you got a gift, not a power supply. These guys spent a great deal of time and thought on shipping, and packaging to ensure it arrives safe and in good shape. They also took care of "what to do with the extra cables" issue. you really don't want to discard them in the case you need them later, but hate to store unused stuff and become a hoarder. Their solution isn't perfect, but helps

Cons: none

1 out of 5 eggsWorked for 2 days

Pros: It worked for 2 days

Did not burn my house down

Cons: It died right in front of my and my client.

There seems to be a short somewhere near the input socket. Moving the plug around on 3 different cords cause power to come back on for a few seconds

Other Thoughts: I order from newegg every week, sometimes several times a week.
This supply is going in a $4K system for a client and it failed right in front of both of us.

The only saving grace here is NewEgg offered an advanced replacement option in this case.

I have installed and own many platinum and gold rated Seasonic power supplies and this is the first bad unit for me.

Manufacturer Response:

Hi Thomas, I am very sorry for the inconvenience. Can you please kindly write to us at newegg@seasonicus.com and let us know what happened so we can report this to our HQ. We have many quality checks in place at our factory and we want to make sure everything is in working order. Thank you very much.

5 out of 5 eggsThe Cadillac

Pros: You can tell from the packaging that they care about their product. This PSU is obviously quality built and high-end, with the best energy efficiency rating you can get. I don't expect to need to utilize the warranty that came with this.

Cons: I probably would have been reluctant to buy this at normal price.

5 out of 5 eggsGreat, High Quality PSU

Pros: > Very high quality PSU, cables, and packaging
> Runs silent (fanless) most of the time on Hybrid mode.
> No coil whine
> The specs are insane for what I paid ($134.99)
> 80 Plus Platinum is pretty much the best you can get in terms of energy savings
> Modular
> Cables were plenty long enough for my system (in a Fractal R4)
> 7 Years of piece of mind that I never have to get another PSU
> Powerful PSU from a top tier brand

Cons: Absolutely nothing other than the MSRP of this PSU is insane. I'm glad I got it on sale or else i'm not sure it would be worth what SeaSonic is asking for it. The PSU itself is solid and I have no reservations on the unit itself.

Other Thoughts: Upgraded from a Rosewill Xtreme 850 that had some coil whine. To put it bluntly, I am so relieved to not hear that irritating sound anymore while gaming.

Although my old Rosewill delivered pretty solid performance, I am planning to add another R9 290X to my build and having a more powerful and energy efficient PSU would be a boon to my system. 5/5, I highly recommend this SeaSonic if you can get it under $150, any higher than that and I would be less inclined to do so.
