SKU CH-7HR5-2B5G5

A 450 W ATX power supply with a 24-pin connector, three SATA ports and a silent temperature-controlled fan

  • Delivers up to 600 W peak power for demanding builds
  • Active PFC improves efficiency and stabilises voltage across 90-264 V input
  • Temperature-controlled PWM fan adjusts speed automatically for quieter operation
  • 20+4 pin ATX connector plus three SATA power ports support modern components
  • Compact 150×140×86 mm form factor fits standard ATX cases

Power supply for gaming desktops

The unit delivers a rated 450 watts with a 600 watt peak for ATX 12V systems. It targets builders who need a straightforward power source for a single graphics card and standard peripherals. Non-modular cabling keeps the price down but adds fixed cables inside the case. It is not for builders who need more storage connectors or modular cable management.

Capacity and headroom

Rated output sits at 450 watts while the peak reaches 600 watts for short bursts. The 12 volt rail is described as strong enough for motherboard, CPU and graphics card demands. Three SATA ports limit the number of drives you can attach directly. It is not for systems that require more drive connections or sustained loads above the rated figure.

Thermals and noise

A temperature-controlled fan adjusts speed automatically to extend service life. Active power factor correction and a dual-tube forward topology aim to improve conversion efficiency and voltage stability. Efficiency is listed at 80 percent under typical loads. It is not for users who demand silent operation certifications or higher efficiency ratings.

Questions about this item

Will the 20+4 pin connector and three SATA ports power my older motherboard and drives?

The 20+4 pin ATX connector fits standard motherboards and the three SATA ports supply power to legacy hard drives or SSDs.

How can I verify the 450 watt rated output is stable after installation?

Check that the fan spins quietly under load and that system voltages in BIOS stay within normal ATX limits.

Does the package include mounting screws and a power cord or must I buy them separately?

The unit ships in its retail box; mounting screws and an IEC power cord are not included and must be sourced separately.
