Msi MAG A1000GLS PCIE5 Gold 1000 Watt ATX 3.1 Fully Modular Smps

The MSI MAG A1000GLS PCIe 5 is a 1000-watt fully modular power supply built to the ATX 3.1 specification, purpose-designed for modern high-performance gaming PCs and AI workstations. Its native 12V-2x6 (H++) connector meets the PCIe CEM 5.1 standard and is capable of delivering up to 600W to a single graphics card, making it a solid pairing for NVIDIA GeForce RTX 50 series GPUs without requiring any adapter cables. Efficiency is at the core of the MAG A1000GLS's design. Holding an 80 Plus Gold certification, the unit operates at up to 90% efficiency under typical loads, which translates to reduced heat output and lower electricity consumption compared to Bronze-rated alternatives. The Active PFC circuit accepts a wide input voltage range of 100–240V at 47–63 Hz, giving it broad compatibility across global power standards including India's 230V supply. For sustained performance under demanding workloads, MSI equips the MAG A1000GLS with a 135 mm fan using a fluid dynamic bearing. This bearing type is chosen specifically for longevity and reduced acoustic output, resulting in quiet operation during everyday and gaming use. The main capacitors are rated to 105°C, indicating a design tolerance suited to prolonged high-load operation. ATX 3.1 compliance means the unit can sustain transient power excursions up to 220% of its rated wattage (approximately 2,200W for up to 100 microseconds) and up to 3x the GPU power rating, accommodating the sharp power spikes characteristic of modern discrete graphics cards. A comprehensive industrial-grade protection suite — covering overcurrent (OCP), overtemperature (OTP), overpower (OPP), short circuit (SCP), overvoltage (OVP), undervoltage (UVP), surge (SIP), and no-load (NLO) conditions — safeguards both the PSU and connected components. Cable quality is addressed through embossed jacket sleeving for improved flexibility and routing, copper-alloy connector terminals for higher current tolerance, and full UL certification on all cables from internal conductors to external braiding. The unit ships with a 7-year manufacturer warranty. **Verified Specifications:** - Wattage: 1000W rated / 2200W peak excursion (up to 220% for 100 µs) - Efficiency: 80 Plus Gold (up to 90%) - Standard: ATX 3.1 / PCIe 5.1 - Modular: Fully modular - Fan: 135 mm, Fluid Dynamic Bearing - Input Voltage: 100–240V~, 47–63 Hz - PFC: Active PFC - Capacitor Rating: 105°C - Dimensions (D×W×H): 150 × 150 × 86 mm - Connectors: 1× ATX 24-pin, 1× EPS 8-pin, 1× EPS 4+4-pin, 1× PCIe 5.1 16-pin (12V-2x6), 4× PCIe 6+2-pin, 11× SATA 15-pin, 4× Peripheral 4-pin, 1× FDD 4-pin - Protections: OCP / OTP / OPP / SCP / OVP / UVP / SIP / NLO - Warranty: 7 Years
