FSP Group SP400-AD 350W Power Supply - 9PA350DR00

FSP Group SP400-AD 350W (9PA350DR00) is a compact ATX power supply for budget and office configurations where you seek stability without unnecessary extras. With 350W power and 85% efficiency, it is more than enough for systems with an economical CPU and a modest GPU or integrated graphics. The active PFC and 120mm fan help for more stable operation and lower noise compared to very basic no-name PSUs. The format is standard ATX with a length of only 140mm, making installation easier even in more compact cases.

What you get

With real output power on the DC 3.3/5/±12 V lines, this power supply is aimed at typical home/office configurations, light gaming, or media centers. You have the full set of basic connectors – ATX 24-pin for the motherboard, 8-pin + 4-pin CPU for powering the processor, and PCI-E 6+2-pin for a lower to mid-range graphics card. The four SATA connectors are fully sufficient for a combination of SSD, HDD, and optical drive, while the two Molex and Floppy cover older hardware or additional fans and accessories. The active PFC and 85% efficiency reduce excessive heating and losses, which means more stable operation under prolonged load.

• Power 350W – sufficient for budget configurations with an economical CPU and one non-demanding GPU card.
• Efficiency 85% – less loss in heat and lower load on internal components compared to the most basic PSUs.
• Active PFC – better voltage stability and more efficient use of mains power at 200–240VAC.
• 1 x PCI-E 6+2-pin – allows you to power a discrete graphics card from a lower/mid-range class without needing additional adapters.
• 4 x SATA, 2 x Molex, 1 x Floppy – enough outputs for SSD, HDD, optical devices, and older hardware or fans.
• 120mm fan – a larger fan means better airflow at lower speeds and quieter operation.
• Compact ATX format 140 x 150 x 86 mm – easy installation in most standard cases, including shorter chassis.
• Non-modular design – all cables are fixed, simplifying installation, although at the expense of more limited cable management.

Who it is suitable for

This power supply is a good choice for office machines, budget home PCs, light gaming on less demanding hardware, and media/streaming systems without a heavy GPU card. If you plan a high-end gaming configuration, overclocking, or a powerful graphics card with a high consumption profile, you will likely need a stronger and certified model here.

The combination of 350W power, 85% efficiency, active PFC, and a full set of connectors in a compact ATX body makes the FSP SP400-AD 350W a practical and reasonable choice for stable yet economical configurations.
