4 out of 5 eggsGood while it lasted

This review is from: SeaSonic X-1050 ( SS-1050XM2 ) 1050W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Built my desktop and was recommended this PSU at the time and it was silent. Powerful.

Video card demanded 500W so this was a must and no brainer.

Cons: Out of nowhere, it works one day, stops the next. No warning.

Other Thoughts: I believe it's still under warranty so I'm still trying. I'm just hoping services is as great as the unit if not greater.

3 out of 5 eggsNot a Very Quiet Fan

This review is from: SeaSonic X-1050 ( SS-1050XM2 ) 1050W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: When the fan is off this is a very quiet stable, psu. But with my rig - a open case with 4 Raid 0 2TB WD hard drives, a Mushkin 480GB SSD, an LG BRD and an ASUS Silent 640, the fan comes on every few minutes and is quite obvious and annoying.

Cons: See above. The fan seems noisy compared to most other PSU units I've used. My 1000w Coolermaster silent - with the fan on constantly - is much quieter - almost as quiet with the fan on as the SeaSonic with the fan off. Silent PC Review gave this model a great rating and called the fan very quiet but it isn't for me.

Pros: I bought this power supply in May of 2012. I been running it in a home server for over 3years straight! Zero issues. Very silent, can't even hear it running. I am glad I bought this power supply over some of the other competitors. Very reliable.

Cons: None no issues with this.

2 out of 5 eggsUpdate after three months

This review is from: SeaSonic X-1050 ( SS-1050XM2 ) 1050W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Good brand name. Silent.

Cons: Stopped working after three months almost to the day.

Other Thoughts: I have started an RMA with SeaSonic and I am expecting things to go smoothly. I am very disappointed that this unit failed in such a short time from a company with such a good name.

5 out of 5 eggsOne of the Best Psu's

This review is from: SeaSonic X-1050 ( SS-1050XM2 ) 1050W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Quality
Jonny Guru recommended
Silent
Incredibly stable voltage's
Made in USA

Cons: one of the modular cable sata power pugs back came off and exposed the wires. never seen that happen before.

Other Thoughts: This is the best PSU I have used in a system to date! When monitoring the voltages i was amazed to see them exactly at what they were supposed to be no + or - at all...I have never seen that before. 3.3v =3.3 volt 5 volt = 5 volt...etc quiet operation,even mode for silent operation. only problem i had was after i put my system together and wired it up, i double checked everything like always and noticed on one of the sata power plugs the back was missing and the wires were exposed, this could have been bad if they touched the case while on, I have never seen that before and I have been building pc's for 15 years. it is a modular psu so i just removed that whole wire and used a different wire in its place.

Pros: Every thing about this PSU is great. I had no problems installing it in to my build. it comes with everything you might need for cable management to a nice storage bag for not used cables.

Cons: The cables are a little stiff in bends.

5 out of 5 eggsWas a great deal

This review is from: SeaSonic X-1050 ( SS-1050XM2 ) 1050W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Had everything possible you could think of to install correctly.

Cons: none that I can think of ...

Other Thoughts: SeaSonic makes power supplies for other companies like EVGA, Corsair, etc ... So why not buy it straight from the main source?

4 out of 5 eggsGood PSU, not as silent as hoped

This review is from: SeaSonic X-1050 ( SS-1050XM2 ) 1050W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: For a gigawatt + PSU price is really good especially considering it is fully modular and from a trusted company. The option to run the PSU in a "silent" mode is quite nice, but more on that later. Cable lengths are quite good and should do well in any standard to mid size tower atx case. Quality of the sleeving on the cables is also nice, however I wish the shrink wrap was closer to the ends on the motherboard connector. Included accessories in the box are also incredible, a bag for all of the modular cables, cable management velcro straps, and a bag for the psu itself. This is well above and beyond what I expect to get with a psu. Overall this is a really good Power supply and I am happy that I picked this up.

Cons: While operating in a silent mode and only spinning under certain loads, it is easily the loudest fan in my system when running. Kind of a bummer when I'm showing off my super silent pc, but the moment the PSU fan kicks on...ouch. Drowns out 2 case fans, 5 radiator fans, and a d5 vario pump.

The coloring choice has me baffled a bit, the gold on the intake and lettering won't match many current schemes on motherboards or graphics cards and although it would have already been face down in my case others may not have that luxury.

Other Thoughts: I am happy that I picked this up, just wish that fan was a touch quieter under load, and definitely shouldn't be the loudest fan on my system. If would have just been quieter than my current fans under load this would have been a 5 egg product for me.

5 out of 5 eggsI really like it.

This review is from: SeaSonic X-1050 ( SS-1050XM2 ) 1050W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Silent or very near silent.
Lots of POWA!
Lots of PCIE cables.
Energy efficient.
Great price.

Cons: Color? I don't see it while installed so...

Other Thoughts: I bought this for a Folding machine. Team 32! WOOT!

The machine is running:
small 64 GB SSD
16 GB DDR3
Core i7-2600 and..... wait for it....
3 X R9-280x video cards.

When cool, the fan does not spin thus it is silent. When warmer, the fan spins very slow but remains virtually silent.

I couldn't ask for more than silent operation, plenty of PCIE plugs, lots of power and energy efficient.

P.S. Check out Folding At Home via Stanford University to see if this is a project you might be interested in.

5 out of 5 eggsReally High Quality PSU

Pros: High build quality. Does a great job at powering my system with an OC'd FX-9590 and a R9 290 Tri-X. Nice assortment of cables. Well crafted cables, PSU, and packaging.

Cons: Some of the cables could be a little bit longer.
