ATX12V V2.3/EPS 12V V2.91
80 PLUS GOLD Certified
Active PFC, SLI Ready

The very first full modular multi-output ATX, high-wattage power supply that has ever obtained the 80PLUS Gold certification is introduced by Sea Sonic. This coveted power supply is named “X” and is offered in a 750 watt version to fulfill computer enthusiasts’ need for the ultimate power source.

Featuring a pending design of “DC Connector Module with Integrated VRM”, the X Series is set to achieve both near-perfect DC to DC conversion and fully modularized design without compromising efficiency. There's finally a product that delivers the complete package: ultra-high efficiency, greatly improved dynamic response and customizable cable arrangement that is tailored to meet any individual’s needs.

As a leading provider of silent power supplies, Sea Sonic delivers a true breakthrough solution for thermal and noise management. The X Series adopts a clever “Hybrid Silent Fan Control” design, which offers three distinct operation modes, fanless mode, silent mode, and cooling mode. The X automatically adjusts fan mode and speed according to the ambient temperature level. This brand new design not only optimizes heat dissipation, but also prolongs the lifespan of the system by reducing unnecessary fan rotation. To make the X Series even more robust and exciting, Sea Sonic offers a Sanyo Denki San Ace PWM Silent Fan, the best fan there is in the industry, and takes advantage of the PWM feature.

ATX12V and EPS12V Compatible Compatible with the ATX12V v2.3 and EPS12V v2.91 standards, the Sea Sonic X750 provides maximum power stability to drive the processors as well as other components for desktop and server computer systems.
750W Maximum Power The Sea Sonic X750 power supply provides a maximum power of 750W to deliver safe, reliable output for high-end computer systems. A strong +12V single rail ensures the maximum provision of 12V power to energy-hungry components such as CPU and VGA card, minimizing the likelihood of overload shut down.
80 PLUS Gold Certified The 80 PLUS Gold certified power supply provides high power efficiency of at least 87% at any load between 20% and 100%, saving your money on your electrical bill, reducing heat in your computer's system and prolonging its life.
Quad PCI-E Connectors With four 6P/8P PCI-E connectors, the Sea Sonic X750 is ideal for building up a SLI or CrossFire gaming system.
Modular Cable Design The modular cable design allows use of only the cables you need resulting in improved internal airflow and reduced system clutter.
Efficient Cooling The Sanyo Denki San Ace PWM Silent Fan plus Hexflo honey comb cutouts increase overall airflow in the power supply enclosure and help remove heat from the chassis simultaneously.

Razor 4/24/2013 10:20:59 AM Tech Level: 4/5 Ownership: 4/5 Verified Owner	Rating: 5/5Update Pros: 750W Gold Fully modular Warranty Cons: NONE, read other thoughts.. Other Thoughts: I bought this power supply over 2 months ago and i did review it with 4 eggs because of coil whine. This is an update to that review. Having owned for 2 months i no longer hear the coil whine! Almost done a RMA but decided to wait and see if i would either to used to it or if it would go away on its own, also seasonic has great warranty and from what i have read they honor it so i am glad i waited. I have bought many parts from Newegg and i am sure that if i need a RMA it will not be an issue... Did you find this review helpful? Thanks for the valuable feedback you provided!

LazarusIV 4/23/2013 1:08:51 PM Tech Level: 5/5 Ownership: 4/5 Verified Owner	Rating: 5/5Fantastic Power Supply Pros: - Excellent build quality / construction - Peerless packaging and accessories - Flawless power delivery Cons: - Not a one!!! Other Thoughts: This is an absolutely phenomenal power supply. It powers my AMD 965BE processor and 2 GTX 470s perfectly, overclocked and everything! You know you're buying Seasonic quality without paying for the Corsair name. If you're considering buying a Seasonic product, DO IT NOW!!! Did you find this review helpful?

N/A 4/23/2013 11:18:17 AM Tech Level: 4/5 Ownership: 4/5 Verified Owner	Rating: 1/5SeaSonic Goes BOOM Pros: I thought the quality. Cons: The power supply just blew up and really, I hadn't used the power supply in 2 years. Just recently hooked up to to a Sandy Bridge system. Loaded the system and then moved to my desk, booted it up and it made a GUN SHOT like popping noise. No more power. Other Thoughts: Is it junk or a faulty build? Did you find this review helpful? Thanks for the valuable feedback you provided!
nubbinator 4/15/2013 10:51:08 PM Tech Level: 4/5 Ownership: 4/5 Verified Owner	Rating: 5/5Great PSU Pros: Quiet, great efficiency, good reliability, nice long warranty, good looks, fully modular, cables are nice and long, sleeved cables. Cons: Sometimes get coil whine, sense wires makes sleeving the cables a pain. Other Thoughts: When I updated my GPU drivers, I got horrible coil whine in Minecraft. The new drivers got rid of it, but it is something to be aware of. Other than that and the added pain that having two wires go to the same pin cause for sleeving, this PSU is fantastic. I can't hear it at all and it delivers solid power. Did you find this review helpful? Thanks for the valuable feedback you provided!
Goldio 4/12/2013 9:13:06 PM Tech Level: 3/5 Ownership: 2/5 Verified Owner	Rating: 3/5Almost double D.O.A. Pros: Great packaging. Modular. Quiet so far. Pretty black. Cons: Very high false D.O.A. Rate. The first one i bought would not start or make any sound or indication that it was receiving power (some have lights so when it's connected to AC you know that it is ready to go) and no hope that it was going to work. I RMAd it through Newegg only to receive another D.O.A. I called newegg and got yet another RMA label, but i also decided to email Seasonic to see what they had to say. " Thanks for contacting Seasonic - Customer Service Dept. Please try Power Supply Jump Start method for testing the PSU first. http://seasonicusa.com/RMABeta/JumpStart/JS.pdf Be sure to plug both the 10 and 18 pin connectors into the P/S slots labeled M/B, then connecting with either dvd-rom or case fan for double make sure." After doing the weird test of shorting out the main connector while having only a fan hooked up, the power supply was able to run. I hooked it up to my motherboard, cpu, HDD, and GPU and it worked. I Really think that Seasonic should view these reviews from time to time because i'm betting that a good number of D.O.A.s are this problem. While not convenient it's nice to know you can easily fix it. Other Thoughts: Seasonic should patrol reviews and give out this info more. Would have possibly saved me a couple days and 10 bucks shipping it to newegg. I will also review this once again after I have thoroughly used it to give a more accurate detail of it's overall performance. 2 out of 2 people found this review helpful. Did you?
