Power Supply Evolveo P1200 ATX 3.1 1200W 80+ Platinum

The Evolveo P1200 ATX 3.1 1200W 80+ Platinum power supply delivers continuous 1200W output designed for high-performance desktop systems and gaming rigs. It supports the ATX 3.1 form factor and PCIe Gen. 5.1 power delivery for modern graphics cards, offers 80 PLUS Platinum efficiency to reduce energy loss and heat, and uses premium Japanese capacitors and a 140 mm HDB fan to provide reliable, quiet operation. The unit is fully modular and includes a comprehensive set of removable cables for flexible installation and improved internal airflow.

Advantages

High efficiency up to 94% at typical load reduces power loss and operating temperatures while lowering fan noise. Fully modular cabling enables tidy builds and better airflow. Premium Japanese capacitors rated to 105 °C increase component reliability and longevity. Compact 158 mm width allows installation in smaller cases while still providing 1200W continuous power. Integrated APFC, MultiFlow airflow design and a 353-hole honeycomb inlet improve cooling and power stability. The supply includes eight protection mechanisms (OTP, OVP, UVP, SCP, OCP, OPP, NLO, SIP) and comes with a three-year warranty.

Suitable for

• High-end gaming PCs with modern GPUs (PCIe Gen. 5.1 compatible)
• Workstations for video rendering and content creation
• Systems requiring a compact but powerful ATX 3.1 power supply
• Custom builds where modular cabling and clean airflow are important

When it may not be suitable

This power supply may be unnecessary for basic office or home computers that consume far less power than 1200W, where a lower-wattage unit would be more cost‑effective. Large or unusual cases requiring non-standard PSU dimensions should be checked for compatibility despite the supply's compact 158 mm width.

How to use

Install the power supply into a compatible ATX 3.1 case following the motherboard and case manufacturer instructions. Connect only the required modular cables to the PSU and the components: main 24‑pin ATX to the motherboard, EPS 4+4 to the CPU power socket(s), PCIe 6+2 and 12V-2×6 connectors to the graphics card(s), and SATA/Molex to storage or peripherals as needed. Use the supplied 230 V mains cable to connect to AC power. Ensure adequate ventilation around the unit and verify all connections before powering on the system.

What to consider before purchase

• Confirm your system's total power draw to ensure 1200 W is appropriate
• Check case compatibility for a 158 mm wide power supply
• Verify the included cable types and lengths match your motherboard, GPU and drive layout
• Ensure your GPU(s) are compatible with the PCIe Gen. 5.1 power connectors provided

Usage recommendations

For stable, long-term performance, route and secure only the cables you need to maintain unobstructed airflow, keep intake/exhaust paths clear, and allow the HDB fan to operate with adequate clearance. Periodically inspect connections and dust filters to preserve efficiency and thermal control.
