X-Series 650w '80 Plus Gold' Modular Power Supply

The very first full modular multi-output ATX, high-wattage power supply that has ever obtained the 80PLUS® Gold certification is introduced by Seasonic, this coveted power supply is named “X” and is offered in various versions.

Featuring a patent 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. After a long wait, finally there is 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.

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 lifespan of the system by reducing unnecessary fan rotation. To make the X Series even more robust and exciting, Seasonic offers Sanyo Denki San Ace Silent Fan on X, the best fan there is in the industry.

Superb PSU's

I bought my Seasonic X-650 back in 2009 if I remember correctly, it has been in three systems, and performed without an issue in all of them. It is quiet too, in fact, it's pretty rare I actually get to witness the fan spinning.

The only issue with my old one is that it is not Haswell ready, as in when the PC hibernates it does not want to come back to like with a keystroke or mouse shake, though I believe this is not an issue with newer models as Overclockers have them on their Haswell compatability list.

My PSU is still performing as well as it did when I bought it, I have had no regrets with this purchase, well maybe I should have bought the 850w model, great PSU's which to be honest I feel are just about as good as the Platinum counterparts when you look at the specifications, benchmarks, and running costs.


Fantastic quality, no need for more watt

I got this to replace an OCZ GameXStream 700w that failed after 5 years of service and it turned out to be a silver lining.
This PSU is better in every single way possible. The build quality is leagues better, it's much heavier and modular with flat cables for easier concealment etc.
Most of all the quality of the power is MUCH better. I gained 200mhz on my CPU overclock and can now run my RAM at 2133mhz stable whereas before the max was 1866mhz.
A seriously good and underrated PSU. Buy with confidence. If you're running a single top of the line GFX card even with multiple hard drives and 16GB RAM this is going to be all you need power-wise.
