White ATX 3.1 unit for modern builds

The Antec GSK850 V2 WHITE US is an 850W ATX 3.1 power supply finished in white. It targets gamers and enthusiasts who need PCIe 5.1 readiness and full modular cabling. The 12V-2x6 connector supports current-generation graphics cards without adapters.

PhaseWave LLC plus DC-DC topology under load

PhaseWave design combines LLC resonance with DC-DC conversion to keep voltage regulation tight during sustained demand. 80 PLUS Gold certification confirms high efficiency across typical operating ranges. Zero RPM Manager stops the 120mm silent fan at low load and spins it up only when thermal conditions require active cooling.

Full modular braided cables simplify daily assembly

Every cable detaches so only the needed leads stay in the case. The set includes a 24-pin motherboard lead, one 16-pin PCIe 5.1 12V-2x6, two 8-pin CPU, four 8-pin PCI-E, eight SATA and four Molex connectors. CircuitShield protections cover OCP, OVP, UVP, SCP, OPP, OTP, SIP and NLO for reliable long-term operation.

Questions about this item

How quiet is the 120mm Silent Fan with Zero RPM Manager during all-day loads?

The 120mm Silent Fan stays off at low loads thanks to Zero RPM Manager, then spins only when needed for quiet, efficient cooling.

Which cables must I already have to use the 1 x 16(12+4)pin PCIE 5.1 12V-2x6 connector?

The 16(12+4)pin PCIE 5.1 12V-2x6 cable is included in the box; no extra cables are required for that connector.

Will the 100-240 V input and 80 PLUS Gold efficiency work reliably with an older motherboard that uses a 24(20+4)pin socket?

Yes, the bundled 24(20+4)pin motherboard cable fits legacy 20-pin and modern 24-pin sockets, and the wide input range handles global mains voltages.
