PROLAB DESIGN XPower XP-1250P 80+ Platinum Fully Modular ATX 3.1 Power Supply ( 1250W )

The PROLAB DESIGN XPower XP-1250P is a 1250-watt ATX 3.1 compliant power supply carrying an 80 Plus Platinum efficiency certification. Built for high-demand gaming rigs and professional workstations, it delivers up to 1250 W of continuous power and ships with a native 16-pin PCIe Gen 5.1 (12V-2×6 / 12VHPWR) cable rated for up to 600 W GPU power delivery, making it ready for NVIDIA GeForce RTX 40 and RTX 50 Series graphics cards out of the box. At the heart of the XP-1250P are 105 °C-rated Japanese electrolytic capacitors. Operating within their thermal headroom even during sustained heavy workloads, these capacitors help maintain stable voltage output and contribute to the unit’s longevity. Cooling is handled by a 120 mm fan using a Hydro Dynamic Bearing (HDB), a design that reduces mechanical friction for quieter operation. The fan’s PWM control allows it to ramp speed up under load while staying quiet at idle or light usage. The fully modular cable system means every connector — including the 24-pin ATX motherboard cable — detaches when not needed, reducing internal cable clutter and improving airflow inside the chassis. The included cable set covers: one 24-pin ATX (600 mm), two 8-pin (4+4) EPS CPU cables (650 mm), two 8-pin (6+2) PCIe cables plus one U-cable (550 mm), and the 16-pin 12VHPWR cable (600 mm). The unit is compatible with a broad range of modern platforms, including Intel LGA1851, AMD AM5, and AMD Threadripper TRX5/WRX8 sockets. The XP-1250P carries a 7-year warranty and is sold under product code XP-1250P-PLATINUM.
