Flex ATX 500W power supply
The FSP FlexGURU Pro delivers 500W of continuous power in the Flex ATX form factor, making it suitable for small form factor PCs, 1U industrial chassis and NAS enclosures. It carries 80 Plus Gold certification and uses a single +12V rail to supply stable voltage to demanding components. A universal mounting bracket is included for broad chassis compatibility. All cables are non-modular, all-black and rounded for easier routing in tight spaces.
Thermals noise and power draw
A 40mm double ball-bearing fan with intelligent speed control manages cooling while keeping acoustic output low during typical workloads. Gold-rated efficiency above 90% reduces waste heat and lowers energy draw from the wall. Active PFC and a 100-240V input range ensure clean power delivery across global mains supplies. Premium Japanese electrolytic capacitors support tight voltage regulation under sustained load.
Upgrade path and fit
This unit replaces older, lower-wattage Flex ATX supplies when a build requires more headroom for discrete graphics or additional drives. The two 6+2-pin PCIe connectors and four SATA power plugs support a modern GPU and multiple storage devices. Builders staying with non-modular cabling and the Flex ATX footprint will find a direct mechanical and electrical fit. Those needing fully modular cables or higher wattage should consider other form factors.

Questions sur cet article
How is the Flex ATX unit with its universal bracket installed, and which step is often missed?
Mount the PSU in the chassis, attach the universal bracket to match the case screw pattern, then connect the fixed 20+4Pin, two 6+2-Pin PCIe and four SATA cables; the step often missed is securing the bracket before routing cables.
What maintenance or replacement will the 40 mm 2-ball bearing fan need later?
The 2-ball bearing fan is rated for long life; typical maintenance is occasional dust removal with compressed air, and replacement is only needed if bearing noise appears after years of continuous operation.
What limit appears first under sustained full load on the single +12V rail?
The 500W maximum power and 80 Plus Gold efficiency ceiling; at continuous 500W draw the unit reaches its thermal and current design limit before the single +12V rail regulation does.
