Silverstone HELA 850R Platinum PSU

This 850W ATX 3.0 compatible power supply delivers fully modular cabling with super flexible black flat wires. All Japanese electrolytic capacitors support continuous 24/7 power output at 50 operating temperature. A 135mm FDB fan provides ultra silent cooling with semi-fanless and delayed shut-off functions. The unit includes a 12VHPWR connector for PCIe Gen 5 graphics cards.

Suitable for ATX 3.0 builds with PCIe Gen 5 GPUs

Builders assembling systems around modern high-end graphics cards will appreciate the native 12VHPWR connector and Platinum Cybenetics efficiency. The 180 degree angled SATA connectors simplify cable routing in drive cages. Anyone needing a non-modular design or lower wattage for a compact budget build should consider other options.

Native 12VHPWR connector for PCIe Gen 5

The included 12VHPWR cable enables direct connection to ATX 3.0 and PCIe Gen 5 graphics adapters without adapters. This single specification determines whether the PSU matches a next-generation GPU requirement. Verify your graphics card power interface before purchase.
