AJ FUNK CO

AJ FUNK CO 300W ATX Power Supply 20/24pin 4pin P4 SATA

SKU CH-E147-3H59N

300 W ATX supply with 20/24-pin, 4-pin P4 and SATA connectors, manual 115/230 V input selection and 70 % efficiency

  • ATX12V 2.0 compliant for broad motherboard compatibility
  • 300 W total output with 264 W on +12 V rails
  • 70 % efficiency reduces waste heat and noise
  • Thermal fan control keeps acoustics low under light loads
  • Over-voltage, short-circuit and over-current protection built in

300W ATX power supply for legacy builds

This SPARKLE unit delivers 300 watts of continuous output and complies with the ATX12V 2.0 standard. It provides a 20/24-pin main connector, a 4-pin P4 connector, four peripheral connectors, one SATA connector and one floppy connector. The supply suits older desktop systems that still rely on these interfaces.

Thermal control and protection under load

An internal 80mm 12V DC fan runs with a Noise Killer thermal speed control function to keep noise low during sustained operation. The unit includes output over-voltage, short-circuit and over-current protection plus a re-settable power shut down feature. It has passed 100% hi-pot, ATE and burn-in testing for reliability.

Check connector needs and input voltage setting

Verify that your motherboard requires only a 20/24-pin main plug and a single 4-pin P4 plug for CPU power. Confirm you have no more than one SATA device and up to four peripheral devices to match the provided cables. The manual voltage selector must be set to either 115V or 230V before connecting to mains.

Questions about this item

How loud and hot does the 80 mm fan get when the PSU runs continuously at full load?

The internal 80 mm fan uses thermal speed control to keep noise low while maintaining safe temperatures under continuous operation.

Which motherboard and drive connectors must my build already provide for this unit to work?

It requires a 20/24-pin main power socket, a 4-pin P4 CPU socket, four peripheral sockets, one SATA socket and one floppy socket.

Will the 300 W output and 70 % efficiency work reliably with older components that draw heavily on the 3.3 V and 5 V rails?

The 3.3 V and 5 V rails share a 120 W limit with defined cross-load rules, and the +12 V rails deliver up to 264 W combined for legacy hardware compatibility.
