Trade-offs
- Minimal or ITX builds needing a compact power supply; this is full-size ATX form factor.
- Users seeking the absolute highest wattage for multi-GPU or extreme overclocking beyond 750W.
- Budget buyers looking for the lowest entry price; Gold efficiency and Cybenetics certification add cost compared to Bronze-rated units.
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.
