Questions about this item

How loud and hot does the 400W Flex ATX supply get when it runs 24 hours a day?

The unit is rated for continuous 400W output at 40 degrees, uses a Japanese main condenser and active PFC, and its black painted shell is designed for strong heat dissipation and moisture protection.

Which cables or connectors must I already have to install this fully modular 400W Flex ATX supply?

Because the supply is fully modular you choose only the cables you need; the unit provides a 20+4 pin main connector, an 8 pin CPU connector, two 6 pin graphics connectors, two SATA ports and two D-type bus connectors.

Will this 400W Flex ATX supply work with my older motherboard that uses a 20 pin main power socket?

Yes, the 20+4 pin main connector splits to fit a legacy 20 pin socket, and the 90-264V input range matches older systems.
