1050 | 1250W

MAXTYTAN is the flagship PSU series of Enermax. High end components and years of experience in power supply technology allow Enermax to create a product with the highest standards of efficiency and reliability. With over 94% of efficiency, the MAXTYTAN series is certified 80PLUS® Titanium. All models have a 139mm Twister Bearing fan with semi-fanless function, granting an extremely quiet operation. The fully-modular PSU comes with individually sleeved cables (SLEEMAX™) offering further protection and the highest flexibility for system installation. This high-end PSU is designed for professional systems requiring the highest standards in quality and performance.

The 80PLUS® Titanium-certified power supply achieves up to 95% efficiency at 230VAC between 20 and 100% load. This not only results in low heat generation but also reduces its own CO2 footprint.

MAXTYTAN helps systems to meet the EU eco-design directive 2013 ErP Lot 6 and 2014 ErP Lot 3 (< 0.5W in standby mode*) due to a high-efficient 5V standby (+5Vsb) circuitry. Moreover, it supports EU regulation no. 617/2013 demanding amongst others 85% efficiency at 50% load and 82% at 20% and 100% load.

* only in combination with an ErP ready mainboard


The DC-to-DC design generates the secondary voltages (+5V and +3.3V) from the primary voltage rail (+12V). The positive effect is higher efficiency, clean output voltages (low ripple noise), and perfect voltage regulation at all loads.

Six 6+2P (8P) PCI-E connectors and a massive 12V rail ensure power for multi-GPU systems (MGPU & SLI™) and overclocked processors.


Coolergenie is a semi-fanless fan controller for up to three external fans. Monitoring the CPU fan speed via PWM, the case fans start to spin after reaching 40% (Whisper Mode) or 55% (Silence Mode) of CPU fan speed. Coolergenie also provides a fan delay function to cool the system 40 to 60 seconds after shut down. This can prolong the lifetime of your components.


SLEEMAX™ cables are individually sleeved, which gives them a high-end look. Besides, they are flatter and more flexible than conventionally sleeved cables and can therefore be laid better behind the cladding.

The fully modular cable management allows an easy system installation and cable routing and improves the air circulation inside the case.

Wattage Meter

MAXTYTAN 1050W and 1250W come with an integrated digital wattage meter optimal for monitoring the current power consumption of test benches or mining systems.


Thanks to the smart semi-fanless control MAXTYTAN series operates completely silent up to a system load of 70% for 1050W and 60% for 1250W model.

The integrated 13.9cm Enermax fan with patented Twister Bearing™ technology ensures an efficient and continuously silent cooling and long lifetime with up to 160,000 hours MTBF.

The patented technology DFR™ (Dust Free Rotation) reduces the dust accumulation on the fan blades.
After starting the PSU, the fan spins in reverse at full speed for a few seconds removing dust.
Afterwards, it returns to normal operation.


Intel® ATX12V v2.4, compliant with the Intel Power Supply Design Guide for Desktop Platform Form Factors Revision 1.31 April 2013.

Full support of the C6/C7 energy-saving functions of Intel® processors, first introduced with the Haswell™ generation.

Worldwide compatibility with automatic 100-240VAC input and up to 0.99 with active Power Factor Correction (PFC).

Quality & Safety

10 Years Manufacturer Warranty.

Enermax only uses high-quality components including first-class Japanese 105°C electrolytic capacitors for maximum stability and durability.

Enermax SafeGuard, the multiple protection circuit that keeps the power supply and the system safe from damage by short circuit (SCP), over voltage (OVP), under voltage (UVP), over current (OCP), over temperature (OTP), over power (OPP) as well as surges and inrush current (SIP).

Non-Stop 24/7 industrial class performance. Full rated power output at 50°C ambient temperature.
