5 out of 5 eggsJust Purchased - Awesome PSU

This review is from: SeaSonic SS-750KM3 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: 1. Works very well
2. Really QUIET PSU, even in Normal mode.
3. Fully Modular
4. Flat power cables.
5. Small but powerful PSU.

Cons: None

Other Thoughts: I purchased this psu to replace my PC P& C 760 W Silencer power supply. The power was working fine but I needed better cable management for my mid-tower workstation/gaming rig. The Seasonic has a lot to live up to because the PC P&C is a quite psu. Lo and Behold, the Seasonic X 750 is even quieter! I can barely tell the fan is spinning in Normal Mode (I only hear the GPU fan) when turn the pc is on). And, I only hear the GPU fan when working under a load. This psu is worth every penny.

This review is from: SeaSonic SS-750KM3 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Unit was on time, well built and works great. Had no problem with length of cables ( Full Case ). Easy to install. Full Modular, SLI Ready, and every thing they claimed.

Cons: Really none.

Other Thoughts: Wish they could offer a custom cable kit. I still think SeaSonic is the best power supplies.

This review is from: SeaSonic SS-750KM3 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: It came in fancy packaging

Cons: it only worked 5 days

Other Thoughts: I bought SeaSonic because from what i read they were the best thing out there... Iv had generic PSU's that last longer then this I most likely will not spend my money on a SeaSonic again.

5 out of 5 eggsSeasonic X750 Gold Power Supply

This review is from: SeaSonic SS-750KM3 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Wow, what can I say this power supply screams quality when I opened the box, it is modular and so it was amazingly simple to install into my new PC. HYBRID Mode the reason I chose Seasonic to begin with, this mode is awesome, read the product descriptions if you don't know what I'm talking about.

Deserved 5 Egg! fast shipping

Cons: There isn't really a con beside the fact that it was only $10 off the original price, I bought it for $139.
Some cable connection point were very tight, but they have gold plate contacts so there's no way I can call that a con.

Other Thoughts: I'm currently RMA this PSu because right after I bought this PSU, newegg sent me a deal for a Seasonic 760W Platinum Power Supply for $99, which is basically the same as this power supply but it's platinum rated and fully modular.

5 out of 5 eggsAbout 3 years. Still works very good.

This review is from: SeaSonic SS-750KM3 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Works very well. Haven't had any problems with it.

I also really liked I was able to select what cables I want to plug in and use vs other Power Supplies that just has them all right there.

And the nice little bag they give you to hold the extra cords is a nice bonus.

Cons: Wasn't Free.

Other Thoughts: Bought this on 4/13/2011 (April 13th, 2011) and still works without problems.

I plan on getting a better video card (AMD R7 or R9) to really put it to the test (as well as be able to play many games).

With no plan to crossfire video cards, this 750 Watt still will be plenty of power.

I wanted to wait until around 3 years to leave a review on this (give or take a few days).

5 out of 5 eggs4 Years and Counting

This review is from: SeaSonic SS-750KM3 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: - Fully Modular
- Quiet
- 80 PLUS GOLD efficient
- Great brand
- Been working for 4 years with 3 years left on warranty

Cons: - Expensive
- Extras come in a nice, pretty package (soft baggie for PS itself, two velcro'd pouches for cables). It's unnecessary and I'd trade that for a slightly lower price.

5 out of 5 eggsWorth every penny

This review is from: SeaSonic SS-750KM3 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: The blog reviews for this lineup of PSUs don't even begin to describe it. This thing is pristine. The packaging it comes with is nothing short of luxurious.

I can't say anything that isn't already said, but know that this PSU uses the best possible components down to every last little capacitor. Some reviews have it stable well past its 750W rating (not that my system will be pulling that much any time soon).

The 750W at the time of my purchasing was significantly cheaper than the 850W. Normally it's just a $20-30 step-up. Still, I have no concerns about this being able to power my future upgrades without any problems.

I have always gone Corsair for my PSUs in the last several years (a couple models of which are actually made by SeaSonic and rebranded nowadays). From now on I'll be purchasing SeaSonic directly and exclusively.

Cons: Absolutely none. And I'm extremely picky. This feels like the most high-end component in my system.

Other Thoughts: i7 4770k @ 4.1ghz

MSI Z87 MPOWER LGA 1150
16GB G-Skill 1866 9-10-9-28 RAM
EVGA 770GTX 2GB

This review is from: SeaSonic SS-750KM3 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: I really liked the quietness of the Seasonic power source and the modular design. So I purchased a second identical unit for another PC under construction.

Cons: After about 3 weeks of relatively modest use the Seasonic power source suddenly died completely. So I changed it out for my second one and immediately revived the computer. I am hoping that Newegg RMA will lead to an early replacement so I can resume setting up my backup system. Also am really hoping that this Seasonic failure was a highly unusual event.

Other Thoughts: Newegg has been highly responsive in this matter.

Manufacturer Response:

Hi Charles, Our apologies for the inconvenience but glad to read that NewEgg has resovled your issue. If you have any further issues or comments, please do let us know at: newegg@seasoniceu.com Thank you.

5 out of 5 eggsGreat PSU

This review is from: SeaSonic SS-750KM3 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Best PSU I have ever come across, so many options that meet all the different connectors there are now.

Cons: none

Other Thoughts: The PSU has evolved before just about everything was powered by the same style plug. Now just about everything is different and this gives you lots of options and you only need to consume the space you need with the modular wiring.

This review is from: SeaSonic SS-750KM3 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: My x650 is awesome, too bad this x750 unit was DOA, hopefully RMA makes good and restores my confidence in Seasonic.

Cons: DOA

Manufacturer Response:

Jonathan, Our apologies for this issue. I hope it is resolved to your satisfaction through NewEgg. If you have any quesitons or concerns, please contact us at: newegg@seasonicusa.com Thank you.
