ASRock Phantom Gaming PG-1600G 1600W 80+ Gold PSU
The ASRock Phantom Gaming PG-1600G 1600W 80+ Gold PSU is a fully modular, high-wattage power supply built for enthusiast and workstation builders who need a reliable, future-ready foundation for demanding component loads. It complies with the latest ATX 3.1 and PCIe 5.1 standards, handles up to 220% power excursion for rapid spike response, and backs every unit with a 10-year warranty.
Why this product
ATX 3.1 and PCIe 5.1 ready
Fully compliant with ATX12V V3.1 and PCIe Gen 5.1, it is compatible with current graphics cards and positioned for future platform requirements without adapter workarounds.
80 PLUS Gold and Cybenetics Platinum certified
It carries both 80 PLUS Gold efficiency and Cybenetics Platinum ratings, alongside a Cybenetics Lambda A noise certification for quieter operation under load.
220% power excursion headroom
The unit can handle transient power spikes up to 220% of rated output, protecting components when GPUs and CPUs draw sharp, short-duration peaks.
Native 12V-2x6 connectors with TempGuard
Two dual-colour 12+4pin PCIe 5.1 connectors include an NTC sensor that monitors temperature at the VGA connector and signals the PSU to respond before heat becomes a problem.
iCOOL fan mode reduces idle noise
When iCOOL mode is on, the 135mm FDB fan stays off during low-to-medium loads and only spins up when temperature or load increases, keeping the system quieter during light use.
10-year warranty and Japanese capacitors
Every capacitor is sourced from Japanese manufacturers, and ASRock backs the unit with a 10-year warranty — among the longest in the category.

- Compatible with ATX 3.1 motherboards and cases accepting a standard ATX PSU footprint (180 x 150 x 86 mm).
- Natively supports PCIe 5.1 graphics cards via two 12+4pin connectors — no adapter required.
- Provides two 4+4pin EPS CPU connectors, suitable for high-core-count desktop platforms that require dual CPU power headers.
- Includes 8 PCIe 6+2pin connectors, 12 SATA connectors and 6 4-pin peripheral connectors for heavily populated storage and expansion configurations.
- iCOOL fan-off mode requires the iCOOL switch to be manually enabled; with the switch off, the fan runs continuously regardless of load.
- 5V BOOST mode boosts the +5V rail to approximately +5.15V and must be enabled via a physical switch; it is not active by default.
Best for
- High-end single or multi-GPU builds that require substantial continuous 12V current (133.3 A) and native PCIe 5.1 connectivity.
- Noise-sensitive enthusiast rigs where the Cybenetics Lambda A rating and iCOOL fan-off mode during light loads matter as much as raw wattage.
- Future-proofing builders who want ATX 3.1 and PCIe 5.1 compliance today so the PSU remains current for the next platform upgrade.
- Long-term system builders who value the 10-year warranty and 100,000-hour MTBF rating as indicators of intended longevity.
- Storage-heavy workstations that can take advantage of 12 SATA connectors and 6 peripheral connectors without requiring additional hubs or splitters.
Trade-offs
- Compact or SFX builds — at 180 x 150 x 86 mm this is a full ATX unit and will not fit SFX or SFX-L form factor cases.
- Budget-conscious mid-range builds where 1600 W far exceeds the system's actual power draw and a lower-wattage unit would be more cost-appropriate.
- Users who need a semi-modular or non-modular PSU — the fully modular design means all cables, including the 24-pin motherboard lead, must be connected manually and stored separately.
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.
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.
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.
ASRock offers an outstanding 10-Year warranty, guaranteeing long term reliable and peace of mind operation.
