Since its launch in 2010, the 80 PlusR Gold X-series has received countless top reviews and awards. The Seasonic X-series has become the choice of enthusiasts who seek high quality, performance and efficiency.

The new generations of the highly popular X-Series models are made for enthusiasts who are looking for the superior 80 PlusR Gold efficiency label. The new X-Series will include the following models:
- X-Series 650 W / 750 W / 850 W – Enhanced performance
- X-Series 1050 W / 1250 W – Heavy-duty workload and top end performance





The new X-650, X-750 and X-850 models feature our unique integrated DC connector panel with onboard VRM (Voltage Regulator Module). This feature not only enables ideal DC-to-DC conversion and reduced current loss but it also includes Fully Modular DC Cabling to ensure forward compatibility and flexible integration. The already tight voltage regulation has further been improved from ±3 to ±2%, which results in higher efficiency and better performance.

An important feature of the X-650, X-750 and X-850 units is the state of the art cooling that also enables absolute silent running. For manual control, however, there is a selector switch on the modular cable plug side of the PSU, which enables the user to select between traditional fan control (S2FC) and the semi-fanless mode (S3FC). In S3FC mode the fan will only start spinning at loads above 20% of the maximum load. This particularly efficient fan control design is complemented by top quality Sanyo Denki San Ace fans, which are considered to be one of the best on the market today. They feature three-point balancing, copper axel and spoon shaped blades to ensure the most reliable performance.

Amongst the numerous top quality components that the Seasonic X-Series incorporates are the Japan sourced 105°C Aluminum Electrolytic Capacitors, the Gold-plated High Current Terminals and the Dual Sided PCB. The 7-year manufacturer's warranty demonstrates Sea Sonic's commitment to advanced technology, superior quality, and overall long-term reliability and performance.

Are all cables sleeve free. So cumbersome for MITX and collects dust to have 24 pin cable sleeved.

They can be enhanced even more with DSP. But it is nextgen. seasonic don't have it yet.

I've asked this elsewhere, but I'll ask you folks here too. What currently is the benefit of DSP. Is there really any performance benefit for the AX1200i over the X-1250? I'm not asking if it measures better. I mean will my computer, in any useful way, perform better with the AX1200i in it?

The true benefit of DSP will to be able to get better performance from lower cost designs. As it is now though it just makes PSU's more expensive. Also, I don't like adding software control where it isn't needed. It's just another layer of complexity. We have individual components throttling and adjusting voltages. We have Windows turning stuff on and off, up and down. Now we're going to have our PSU's also controlling system power usage. Since no 2 setups are exactly the same, I can just see more blue/black/green screens of death, problems recovering from sleep, video driver crashes, etc. because of it. All of this for 1/2% better regulation and 5mv less ripple.

Convert your Core i5 3570K to Core i7 3770K when powered by this PSU :D.

its your choice honestly no one is forcing you to get this component, this is where the rest of the market is headed to. Id honestly get a 750 W unit

I still say for trusted PSUs

Antec
Corsair
Enermax
PC Power and cooling (Not OCZ series)
Thermaltake (Yes they handle stuff pretty well ive noticed)
Seasonic
