X-Series 850w '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 560W 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.

Nice PSU but no plug

Really efficient and quiet PSU. Handily supplied with a two pin plug... This meant I had to delay my PC testing for yet another day as I had no spare lead. Disgraceful that it isn't supplied with the right socket quite frankly.



Got one of these today to replace my XFX SIlver 850W PSU wic died after 14 months

All I can say is:- A MA ZING

Almost totally silent and rock solid stabilty

Only PSU to consider buying in my opinion




After a recent PSU died, I replaced it with a cheap one, just to keep me going. Now I have finally upgraded to a decent PSU again, I know what I have been missing.

The PSU just oozes quality. From the moment is arrives, you know it was worth the money. It comes with all the cables you could possibly want, in a nice pouch to store all the ones you don't need. Even the PSU comes in a branded suede pouch (not totally sure this is necessary though)

Almost totally silent in most circumstances, as the fan only switches on above 20% load, and even when the fan does switch on, its leagues better than anything I have ever used before. Voltages are rock solid, and cables are all great quality.

Highly recommended!
