Ruth's sister 300W 24-pin ATX power supply 570856-001

SKU CH-V6MN-T7K7Z

A 300W ATX power supply with a 24-pin connector and active PFC for desktop or server use

  • Delivers 300 W for stable desktop operation
  • Active PFC improves input power efficiency
  • Wide 100-264 V input suits global mains
  • Non-modular 24-pin ATX simplifies installation
  • Includes 4-pin CPU connector for processor power

300 W ATX power supply

This 300 W ATX unit delivers power through a fixed 24-pin motherboard connector and a 4-pin CPU connector. It fits desktop and server chassis that require a non-modular design. Active power-factor correction helps maintain efficient draw across the 100-264 V input range.

Sustained-load behaviour

The supply is rated for 300 W continuous output rather than a short-term peak. With zero dedicated 12 V graphics connectors, the 12 V rail serves the motherboard, CPU and peripherals only. Builders running discrete GPUs that need auxiliary power cannot use this unit.

ATX 24-pin interface limits

The 24-pin ATX connector caps motherboard power at the specification's defined limits. A single 4-pin CPU connector restricts processor power delivery compared to 8-pin designs. The 80 PLUS certification listed as other certification indicates a baseline efficiency level without a published tier.

Questions about this item

How much heat and noise should I expect from the 300 W unit running continuously?

The 300 W supply uses active PFC and a non-modular design; typical efficiency falls under an 80 PLUS Other Certification tier, so sustained load will produce moderate warmth and fan noise comparable to other 300 W desktop units.

Which connectors must my motherboard and CPU already provide for this 24-pin ATX supply?

Your board needs a standard 24-pin ATX socket and a 4-pin CPU power header; the unit has no PCIe 12 V pins, so discrete graphics cannot be powered directly.

Will the 570856-001 work reliably with older components that only draw 100 V input?

Yes, the input range spans 100-264 V, so legacy hardware designed for 100 V mains will operate normally with this supply.
