ASRock Phantom Gaming PG-1000G 1000W 80 Plus Gold PSU
The ASRock Phantom Gaming PG-1000G 1000W 80 Plus Gold PSU is a fully modular ATX power supply built for enthusiast gaming builds that demand both current and next-generation compatibility. It meets ATX12V V3.1 and PCIe Gen 5.1 standards, handles power excursions up to 220%, and includes a native 12V-2x6 connector with TempGuard temperature monitoring—making it a practical choice for high-end GPU installations. Backed by a 10-year warranty and 100% Japanese capacitors rated to 105°C, it suits builders who want a long-service-life foundation for a demanding system.
Why this product
ATX3.1 and PCIe 5.1 ready
Fully compliant with ATX12V V3.1 and PCIe Gen 5.1, it supports current high-end GPUs and is prepared for next-generation graphics cards without an adapter.
220% power excursion tolerance
It handles power spikes up to 220% of rated output, responding quickly to transient loads and protecting components during demanding workloads.
Native 12V-2x6 connector with TempGuard
The dual-colour 12V-2x6 connector makes seating confirmation easy at a glance, and the integrated NTC sensor monitors temperature at the VGA connector to ensure safe operation.
Semi-passive iCOOL fan control
In iCOOL mode, the 135mm FDB fan stays off under low to medium loads, reducing noise and improving efficiency; it spins up only when temperature or load demands it.
80 PLUS Gold and Cybenetics dual-certified
Independent 80 PLUS Gold and Cybenetics Gold efficiency ratings confirm consistent power delivery efficiency, while the Cybenetics Lambda A acoustic certification validates low-noise operation.
10-year warranty on a 1000W platform
A decade-long warranty, 105°C-rated Japanese capacitors, and an MTBF exceeding 100,000 hours reflect a design intended for long-term daily use.

- Compatible with ATX form factor cases and motherboards following the ATX12V V3.1 standard.
- Native PCIe Gen 5.1 support via the included 12V-2x6 connector — no adapter required for current high-power GPUs.
- Fully modular cabling means unused cables can be left out, improving airflow in compact and mid-tower builds.
- iCOOL semi-passive mode can be switched off if continuous active cooling is preferred under all load conditions.
- 5V Boost mode raises the +5V rail to approximately +5.15V when enabled; verify your components' voltage tolerance before activating it.
- Not designed for SFX or other compact form factors — this is a full ATX unit.
Best for
- High-end gaming PC builders who need a PSU ready for current PCIe 5.1 GPUs and want headroom for future upgrades without replacing the power supply.
- Enthusiasts prioritising long-term reliability — 105°C Japanese capacitors, an MTBF above 100,000 hours, and a 10-year warranty suit builds intended to run for many years.
- Builders in noise-sensitive environments who benefit from the semi-passive iCOOL fan mode and Cybenetics Lambda A acoustic certification for quieter operation at low to medium loads.
- Overclockers and power users whose systems draw sharp transient spikes, given the 220% power excursion tolerance.
- Neat cable management builds where the fully modular design allows only required cables to be installed, reducing clutter.
Trade-offs
- Budget or mid-range builds that do not require 1000W of output — a lower-wattage unit would be a better-matched choice.
- Small form factor or ITX systems that require an SFX or SFX-L PSU rather than a full ATX unit.
- Workstation or server applications — this is a gaming-oriented ATX PSU, not a redundant or rack-mount power solution.
- Users who need continuous fan operation by default — the iCOOL semi-passive mode must be manually switched off to keep the fan running at all times.
The ASRock Phantom Gaming series power supply supports both current and future standards, fully compliant with ATX12V V3.1 and PCIe Gen 5.1. Ideal for both current systems and future builds, this power supplies can handle up to 220% power excursion and respond swiftly to power spikes, ensuring reliable, safe power for your components.
With ASRock Classic Green connectors, users can easily see if the connector has been plugged properly. The NTC sensor at the VGA connector monitors the temperature and sends signal the PSU to ensure safe operation.
When this switch is enabled, it boosts the +5V voltage to maintain optimal performance. If no voltage drop occurs, the PSU will regulate the +5V rail to approximately +5.15V, ensuring consistent power delivery.
●iCOOL Mode ON: The power supply runs more efficiently. The fan stays off during low to medium loads, reducing noise and improving energy efficiency. The fan only activates when the load or temperature increases.
●iCOOL Mode OFF: The fan runs continuously, regardless of load. This may increase noise slightly but provides consistent cooling and better performance under heavy loads.
Designed for gaming enthusiasts, the Phantom Gaming series power supply unit with 80 PLUS Gold efficiency certification and Cybenetics Platinum & Gold ratings, along with LAMBDA A acoustic certification, it guarantees superior energy efficiency and low noise operation.
The Phantom Gaming series power earning the prestigious Cybenetics Lambda A certification. This recognition underscores the Phantom Gaming series' outstanding noise control performance, making it an exceptional choice for users seeking ultra-quiet operation. The fluid seal design and the herringbone structure provides an extremely long lifespan and noise minimization. The industrial-leading components deliver high efficiency and reliability. 105 °C Japanese-made Capacitor and Solid Capacitor, makes prolonged life span possible. Full suite of protections to keep all components safe during normal to extreme power levels.
ASRock offers an outstanding 10 –Year warranty, guaranteeing long term reliable and peace of mind operation.
