How much power can a fanless power supply deliver? Probably a lot more than you think as SeaSonic is now showing off the Prime Fanless TX-700 PSU at Computex. This model has 80Plus Titanium certification and can output 700W. This model is the successor to the Prime Titanium Fanless 600W. SeaSonic is confident the unit will last a long time as it offers a 12-year warranty.
Its connectivity is updated to include two 4+4 pin EPS connectors, up to six 6+2 pin PCIe power, and up to twelve SATA power connectors. The best part? It holds onto its >94% 80 Plus Titanium efficiency even at 115VAC. Ripple noise suppression has been tightened to 20 mV, and micro-tolerance load regulation to 0.5%. Seasonic picked the choicest aluminium electrolytic capacitors, and worked on improving the thermals even further.
If you don't need 700W, SeaSonic also has a 120mm-long Prime Fanless PX-500 PSU. That model has 80Plus Platinum certification and the same ripple suppression features as its big rother.
