Compact Flex-ATX power supply

The FSP FlexGURU is a 300 W Flex-ATX unit built for small-form-factor PCs, industrial systems and NAS enclosures. Its fully modular ribbon cables and universal mounting bracket simplify integration in tight chassis while keeping airflow clear. 80 PLUS Gold certification and Japanese main capacitors deliver efficient, stable power for continuous workloads.

Suited for space-constrained builds

This supply fits builders who need a high-efficiency, fully modular Flex-ATX unit with a single +12 V rail and industrial-grade protections. It is not for systems that require multiple SATA power connectors or higher total wattage than 300 W.

Single +12 V rail at 300 W

The unit provides one +12 V rail rated for the full 300 W maximum output. This specification determines whether the supply can meet the peak current demands of your components in a compact or industrial chassis.

Perguntas sobre este artigo

What mounting hardware is included with the FlexGURU 300W Flex ATX unit?

The package includes a universal mounting bracket, auxiliary brackets and a special mounting hole design that fits most Flex-ATX chassis and IPC enclosures.

How do I connect the modular cables and which step is often missed?

Plug only the required all-black ribbon cables into the PSU side first, then route them to components; the step often missed is seating each connector fully until it clicks.

When should the 140 mm cooling fan be cleaned or replaced?

Clean the fan intake with compressed air every 12 months or when dust buildup is visible; replace the fan if bearing noise appears or airflow drops noticeably.
