Quiet-focused builders and Modern Standby systems

This unit suits builders who prioritise silent operation through its Zero RPM fan mode at low and medium loads. It also fits owners of compatible Dell 3670 3671 3980MT systems requiring the HU290EM-01 L290AM-00 H290AM-00 form factor. Buyers needing higher wattage for multi-GPU configurations or extreme overclocking should look at higher-capacity units.

525W 80 PLUS Gold ATX with Zero RPM mode

The single specification that decides fit is the 525W 80 PLUS Gold rating combined with the proprietary Dell-compatible pinout used in 3670 3671 3980MT chassis. Verify your case and motherboard require this exact form factor before purchase.

Questions about this item

What motherboard power connectors does this 525W ATX unit provide for my system?

The power supply uses standard ATX 24-pin main and 4-pin or 8-pin CPU connectors that fit any modern ATX motherboard.

Will the Zero RPM fan mode stay quiet when my older components draw very little power at idle?

Yes, the fan stops completely at low and medium loads, so the system remains near-silent even with legacy parts that consume minimal power.

How can I verify the 80 PLUS Gold efficiency is active after installation?

Under typical loads the unit runs cooler and the fan stays off longer, which you can confirm by feeling lower exhaust temperatures and hearing no fan noise at idle.
