180W ATX Gold Power Supply

This 180W ATX power supply carries 80 PLUS Gold certification for high-efficiency operation and lower running temperatures. It targets small-form-factor or low-power builds that need reliable DC-to-DC conversion and Modern Standby support. The unit replaces OEM models such as 3040, 5040 and 7040 in compatible chassis.

Practical Limits of ATX 180W

The 180W ceiling restricts use to systems with modest CPU and GPU power draw; high-end discrete graphics or multi-drive arrays will exceed the available headroom. Zero RPM fan mode operates only at low and medium loads, so sustained heavy loads will spin the fan. Modern Standby wake speeds depend on motherboard firmware implementation, not the supply alone.

80 PLUS Gold Efficiency Rating

The Gold rating guarantees at least 80 percent efficiency at typical loads, reducing waste heat and enabling quieter Zero RPM operation. This single metric decides whether the unit meets the thermal and acoustic targets of a compact build. Builders needing more than 180W continuous power must select a higher-wattage model.

Questions about this item

Which of the listed part numbers — 3040, 5040 or 7040 — should I choose for my system?

Those numbers appear in the supplier title as alternative model references for the same 180 W unit; pick the one that matches your chassis or motherboard documentation.

What does the 80 PLUS Gold rating mean for daily use in my PC?

It guarantees at least 80 % efficiency at typical loads, so the supply wastes less electricity, runs cooler and keeps fan noise lower.

The unit is described as ATX — what does that cap in practice?

ATX defines the physical size, mounting holes and standard 24-pin, 8-pin and peripheral connectors, so it fits any regular ATX case and motherboard.
