ATX 300 W power supply

The In Win IW-P300A2-0 is a standard ATX power supply rated for 300 W maximum output. It suits basic desktop builds or replacement of an existing unit in a compatible chassis.

Continuous 300 W delivery with dual-voltage input

The unit accepts 115 V or 230 V input at 50 Hz or 60 Hz, drawing 8 A at 115 V and 4 A at 230 V. Its +12 V rail supplies 15 A while the +3.3 V and +5 V rails deliver 28 A and 30 A respectively, providing stable power across all rails during sustained loads.

Verify ATX fit and connector needs before ordering

Ensure your case accepts a standard ATX form-factor supply and that your motherboard and drives match the available output connectors. The +5 VSB rail provides 2 A for standby functions, and the combined minor rails support typical legacy and current peripheral demands.

商品問答

How much heat and fan noise should I expect from the 300 W unit when it runs continuously?

The supply draws 8 A at 115 V or 4 A at 230 V and delivers up to 300 W, so sustained load will produce typical ATX heat and fan noise for a 300 W design.

Which motherboard and drive connectors must my case already provide for this ATX power supply to work?

The unit follows the ATX form factor and provides +3.3 V at 28 A, +5 V at 30 A, +12 V at 15 A and +5 VSB at 2 A through standard ATX output leads.

Will the +12 V rail at 15 A support older AGP graphics cards and IDE drives I want to keep?

The +12 V rail supplies 15 A and the +5 V rail supplies 30 A, matching the power needs of many legacy AGP cards and IDE devices.
