Smart Series 700W ATX power supply

This 700 W unit follows the Intel ATX 12V 2.3 standard and carries 80 PLUS certification. It targets mainstream builds that need continuous power for SLI or CrossFire graphics configurations. A single +12 V rail rated at 54 A delivers stable current to demanding components. Non-modular cabling keeps the cost low while covering typical drive and GPU needs.

Thermals noise and power draw

A 120 mm fan spins at 1800 RPM with a ten percent tolerance to move air through the chassis. The supplier states the fan provides excellent airflow at an exceptionally low noise level during normal operation. Efficiency ranges from 80 to 87 percent between 20 and 100 percent load, peaking at 86 percent. Active PFC corrects the power factor across a 100 to 240 V input range.

Behaviour under sustained load

The single +12 V rail design enables non-stop usage with stable performance under continuous loading. Hold-up time is rated at a minimum of 16 ms at 60 percent load, and the power-good signal arrives within 100 to 500 ms. High-quality components are selected to prevent capacitor explosion and leakage during extended runs. The 140 mm depth fits standard ATX cases without clearance issues.

Questions about this item

How do I install this non-modular 700 W PSU and which step do builders often miss?

Mount the 140 mm deep unit in the case, connect the fixed 24-pin, two 6+2-pin PCIe and six SATA cables, then plug the IEC cord into a 100-240 V outlet; the step often missed is verifying the single +12 V rail delivers 54 A for the GPU.

What maintenance or replacement will this power supply need later?

The 120 mm fan runs at 1800 RPM ±10 %; expect to clean dust from its intake every 6-12 months and replace the fan if bearing noise appears, while the 80 PLUS certified efficiency of 80-87 % at 20-100 % load remains stable.

What limit appears first when this PSU runs at sustained load?

The single +12 V rail is capped at 54 A; continuous draw beyond that triggers protection before the 80-87 % efficiency range or the 16 ms hold-up time at 60 % load become factors.
