PCIe Gen 5.0 Support for NV 40+ Series GPUs. (BGA850W, BGA750W)

Please use the correct cable according to the requirements of the graphics card wattage, and must be correctly installed on the graphics card interface.

ATX 3.0 Support

Full-bridge Resonant Converter Design Offer Highly Efficient and Low Noise Output Cost Effectively

Due to the unique design, the Half-Bridge Resonant Converters can output significantly higher power extremely efficiently and the resulting output shows minimal voltage and current ripple. They can operate extremely efficiently across the load curve. This leads to an efficient, high power PSUs with high reliability and component life at the cost of high manufacturing cost.

The PCIe Gen 5 12+4Pin Modular Cable

The PCIe Gen 5 12+4Pin modular cable allows the power supply to support PCIe Gen 5 advanced graphics cards. This cable conforms with the UL specifications for 16AWG – UL 1007 cable standard offering excellent conductivity and heat resistance. The terminals of the connectors are made of a high-quality copper alloy, which can carry a current of up to 9.2A per pin with minimum resistance resulting in excellent conductivity.
Our connectors are adopting the 4 Spring design as suggested by Intel. According to Intel, the advantage of the 4 SRPING design is that it is more reliable, durable, and it can provide a more secure connection compared to the traditional design.

Tested under the most rigorous conditions, the BitFenix BFG1000W & BFG1200W has passed all the PCIe Gen 5 standards with flying colors. They support up to 2x power excursions for a duration of over 100µs guaranteeing stable power outputs for even the latest top tier graphic cards.
The 12VHPWR connector is also tested for reliability and low resistance to offer peace of mind.


The 87+ high efficiency circuit guarantees both energy and money savings for the end user with the added benefits of 80% less heat output and stable power output. This translates to over 30% less power consumption in comparison to standard PSUs.
*87+ ( 0% to 100% load)/ 90+ (40% to 70% load)
100-240V Full range design offer worldwide compatibility, and with high efficiency LLC, Active PFC, DC to DC circuits not only benefits you but also planet Earth with higher energy savings.

PSU Thermal Solution

The BFG1000W and BFG1200W are equipped a ultra quiet 135mm Fluid Dynamic Bearing fan focused on low-noise and efficient-cooling.
With a custom fan curve design, these PSUs can operate in Zero RPM Mode for up to 40% of loading and can operate at sub-500 RPMs for a majority of a typical user scenario. At full load it can quickly ramp up to 1800 RPM offer significantly higher CFM for rapid cooling unlike traditional PSU fans.
