  • Active PFC with 140-300V input range for stable operation

Server PSU for Intel and AMD platforms

This VINTMAR unit delivers 500 watts of continuous power at 40 degrees Celsius with a 600 watt peak rating. It meets ATX 12V 2.31 and EPS 12V 2.92 specifications for modern motherboard compatibility. The supply includes 20+4 pin main, dual 6+2 pin PCIe and 4+4 pin CPU connectors. Builders needing more than two graphics-card plugs or higher continuous wattage should look elsewhere.

Thermals, noise and power draw

A 120 mm PWM fan with hydraulic bearing and eddy-current blades adjusts speed based on internal temperature. High-density honeycomb vents increase airflow through the chassis for efficient heat removal. Active power factor correction operates across a 140 to 300 volt input range. Typical load efficiency is rated at 80 percent.

Dual 6+2 pin PCIe connectors

Two 6+2 pin cables provide up to 300 watts of combined auxiliary power for discrete graphics cards. Cable lengths reach 550 millimetres with an extra 150 millimetre branch for flexible routing. Systems requiring three or more PCIe power leads cannot use this supply.

Questions about this item

How do I install the 20+4Pin mainboard cable and the dual 6+2Pin PCIe cables, and what step is often missed?

Route the 550 mm 20+4Pin cable to the motherboard socket and the two 6+2Pin cables to the graphics card, then press each connector until the latch clicks; the step often missed is seating the 4+4Pin CPU plug on the 650 mm lead.

What maintenance will this 500 W unit need after extended use?

Clean dust from the 120 mm PWM fan and honeycomb vents every few months; the hydraulic bearing fan is not user-serviceable, so replace the entire supply if noise or temperature rises.

At what point does the 600 W peak limit appear during sustained loads?

The supply delivers 500 W continuously at 40 °C; exceeding that level triggers over-current protection, so the 600 W peak is only available for brief transients.
