Seasonic X-Series 1250W Power Supply Review

Seasonic box artwork is subtle and understated in design. We like it.

The power supply ships underneath a user manual, protected underneath foam. The accessories are set to the right of the box.

The bundle includes a thick felt bag with the modular cables inside. A regional specific power cable and user manual is also included. Lastly, the company include a clear bag with plastic and felt cable tidies. There is also a case badge so you can broadcast to the world that your system is powered by Seasonic.

All of the modular cables are held inside a heavy duty felt bag which is split into two compartments. This can be reused and sealed, to store cables which you aren't using.

Cables And Connectors:
(1) 24/20 Pin Main Power Connector
(1) 4/8 Pin ATX/12V/EPS12V Power Connector
(1) 8 Pin ATX/12V/EPS12V Power Connector
(8) 6/8 Pin PCI Express Connector
(2) 4 Pin Floppy Drive Power Connector
(8) 4 Pin Molex Peripheral Power Connector
(11) 15 Pin Serial ATA Connector

The cable quality is excellent, all fully sleeved and high grade 18AWG standard. They include 8 x PCI-E cables to ensure that even the most demanding SLI and Crossfire systems are supported.

  2. A little much for my system, but I see they have dropped their pricing as I saw this before for £270. Its a solid design, but I wonder why Seasonic have so many power supplies in the market now.
