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. Adjustable Fan Control with Semi-Passive ModeThe 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.Technical Details:Dimensions: 150 x 86 x 170 mm (W x H x D)Fan: 135 mm (Fluid-Dynamic-Bearing, automatic control with semi-passive mode)Efficiency: max. 94% @ 50% load, 80 PLUS Titanium certificateActive PFCForm factor: ATX12VPower: 850 W+3,3V: 20 A+5V: 20 A+3,3V & +5V: 100 W+12V: 70 A / 840 W-12V: 0,3 A / 3,6 W+5Vsb: 3 A / 15 WConnectors (removable):1x 24-Pin2x 4+4-Pin6x 6+2-Pin-PCIe14x SATA5x 4-Pin-Molex1x Floppy-AdapterManufacturer warranty: 12 years
