Product Description

Seasonic Prime TX-850 850W 80 Plus Titanium Modular Power Supply UK Plug

Seasonic has entered the competitive arena that is the power supply market once again, this time with the compelling Prime series, this time in the form of the TX which represents the flagship. Offering outstanding efficiency, high performance, modular cable management and chic design, this third generation of Seasonic PSUs manages to offer excellent load regulation with a tolerance of just half a percent.


850 watt power supply with strong 70A single rail

Maximum efficiency due to 80 PLUS Titanium certificate

Silent 135 mm fan with semi-passive mode

Completely modular cable management with flat cables

Six 6+2 pin PCIe connectors for graphics cards


The Seasonic Prime TX is a powerful power supply and provides 850 Watts total output output, meaning that even high-end gaming PCs with demanding processors and graphics cards will be in good stead with this unit. The powerful 12 Volt rail delivers a full 70A and is also certified 80 PLUS Titanium. Seasonic consistently opts for only the highest quality electronic components, and the internal connections are largely wireless.

Furthermore, the completely modular design, with its individually pluggable cables, means that it helps ensure a clean interior along with optimised air flow. The Seasonic Prime TX 850W provides a 24-pin - and two 4+4-pin -cables along with six 6+2-pin PCIe connectors and 14 SATA- and five 4-pin Molex connectors. The result is a PSU with unparalleled connectivity options just waiting to be paired with an enthusiast-class system. Visually, the black power supply with its black-silver grill fits perfectly into just about any case.


The 135 mm fan utilises fluid dynamic bearings, which ensure the unit's smooth operation as well as an exceptionally long operating life. The hybrid switch on the rear panel of the power supply can also be used to switch between automatic fan control both with and without a semi-passive mode. The end result is a power supply that minimises unwanted noise and maximises its cooling power, depending on how much the power supply unit is currently delivering.

It almost goes without mentioning that the Prime TX power supplies have all the necessary protective add-ons that modern high-end models should offer. The load regulation operates with a extremely low voltage tolerance of 0.5%. In addition, Seasonic comes with a full twelve-year manufacturer's warranty.
