Ideal for basic ATX builds

This In Win IPS350CQ20H is a 350 watt ATX power supply designed for standard desktop systems. It provides four SATA connectors for storage drives and optical devices. The unit is built for Haswell-era platform compatibility and suits office PCs or budget workstations that need reliable power delivery.

Quiet operation for everyday tasks

The supply delivers its rated output without excessive fan noise during typical office workloads. Power draw scales with the connected components, keeping thermal output modest in normal use. This behaviour helps maintain a comfortable acoustic environment for work or study spaces.

Steady output under continuous demand

Under sustained load the unit maintains stable voltage rails within ATX specification limits. Thermal management keeps internal temperatures controlled during extended operation. It is not intended for high-end graphics cards or multi-GPU configurations that would exceed the 350 watt capacity.

Questions about this item

How do I install this ATX power supply and which connector do builders often miss?

Mount the unit in a standard ATX case, connect the 24-pin motherboard cable, the 4/8-pin CPU cable, then attach all four SATA power plugs to drives; the step most often missed is the CPU power cable because it sits apart from the main harness.

What maintenance will this 350 W unit need over time?

Clean the intake fan and ventilation grilles every six to twelve months to prevent dust build-up; the internal capacitors are rated for long life and the unit has no user-replaceable parts, so no scheduled component swaps are required.

What limit appears first when this 350 W supply runs at full load continuously?

The 350 watt total-output ceiling is reached before any single rail limit, so sustained draws above that level will trigger over-power protection and shut the unit down.
