Redundant 420W Server Supply
The Silverstone ST42GF is a new redundant server power supply rated at 420W with 80 PLUS Bronze efficiency. It accepts a universal 90 to 264 V input range and uses active PFC with a power factor above .95 at full load. Four internal fans cool the unit while it delivers power through a 24-pin main connector and multiple peripheral leads. A 100,000-hour MTBF at 25 °C under full load indicates long-term reliability.
Hot-Swap Redundant Architecture
The defining specification is the 1+1 redundant configuration with hot-swappable modules that allow a failed unit to be replaced without shutting down the server. Each module can sustain 420W continuous output, and the combined design provides fault tolerance through automatic load sharing. Power fault alarm signals alert administrators immediately when a module loses output, maintaining uptime in critical environments.
Suited For Always-On Rack Servers
This supply suits rack-mount servers that require uninterrupted power and can accommodate the 150 mm by 86 mm by 193 mm form factor with 24-pin, 8-pin EPS12V, 6-pin PCIe, SATA and peripheral connectors. It is not for builders needing higher single-unit wattage, non-redundant desktop ATX builds, or systems that lack the chassis bays and backplane support required for hot-swap module installation.

Otázky k tomuto produktu
How much 12 V current does the 420 W rating actually deliver to the system?
The +12 V rail is rated for 33 A, which is the practical limit for CPU and GPU power draw from this unit.
What efficiency standard does the 80 PLUS Bronze label guarantee at typical loads?
It certifies at least 80 % efficiency at 20 %, 50 % and 100 % load, so waste heat stays low across the operating range.
Will the 150 mm by 86 mm by 193 mm enclosure fit a standard redundant PSU bay?
Yes, those dimensions match the common 1U redundant form factor used in rackmount server chassis.
