Essential Series 550 W ATX power supply
The Silverstone SST-ET550-B is an ATX12V v2.4 unit rated for 550 W continuous output. It uses a single +12 V rail capable of 42 A and holds 80 PLUS Bronze certification for 82 to 85 percent efficiency across 20 to 100 percent loading. A 120 mm fan runs at 18 dBA for quiet operation.
ATX12V v2.4 limits and protections
The design follows the ATX12V v2.4 standard with active PFC above .9 at full load and accepts 100 to 254 Vrms at 47 to 63 Hz. Over-voltage, over-power and short-circuit protections are built in. The single +12 V rail simplifies load balancing for modern components.
Check connectors and clearances before ordering
Verify your motherboard needs a 20+4 pin main connector and an 8/4 pin EPS connector. Two 6+2 pin PCIe plugs serve most mid-range graphics cards. Six SATA, three peripheral and one floppy connector cover drives and accessories. Ensure the case fits a standard ATX depth unit.
