01PORTABLE AIR CONDITIONERS
Quiet Power for High Performance Builds
Tucked away in the chassis, this power supply unit hums quietly while driving demanding hardware. Its compact form factor fits standard cases without crowding other components.
The Seasonic VERTEX GX-850 delivers stable voltage regulation and efficient power distribution, suiting enthusiasts building high-end gaming or workstation systems who value reliability and silence.


02DESIGN
Compact Form Factor for Tight Cases
Measuring 160 mm in length, 150 mm in width and 86 mm in height, the unit occupies minimal space within the computer case. This Intel ATX 12 V form factor allows for easier cable management and better airflow around surrounding components, ensuring a clean interior layout.
COOLING
Silent Operation via Hybrid Control
A 135 mm fan with a fluid dynamic bearing runs on premium hybrid control, adjusting speed based on load to minimize noise. Rated for 50,000 hours at 40°C, the fan ensures long-term quiet operation, keeping the build silent whether idling or under full stress.
CONNECTIVITY
Modern Cables for Next-Gen Hardware
Fully modular flat black cables include an ATX 3.0 compliant 16-pin PCIe Gen 5 connector (12VHPWR), simplifying connections for modern GPUs. Gold-plated terminals on motherboard, CPU and PCIe connectors reduce resistance, maintaining signal integrity and power flow efficiency over time.
