AI Verdict

This 750W 80 PLUS Bronze non-modular ATX 2.52 power supply with a native 450W 12V-2x6 connector is for budget PC builds needing PCIe 5.1 compatibility.

Situational Fit

This 750W 80 PLUS Bronze power supply is a situational fit, primarily for budget builds that need PCIe 5.1 readiness and a native 450W 12V-2x6 connector. Its non-modular design and single dual 6+2 pin PCIe cable mean you'll need to plan your cable routing carefully and ensure your GPU doesn't demand more than 450W from the 12V-2x6 or require multiple separate 8-pin connectors.

If you need more flexibility for cable management or higher power delivery to your GPU, look for a fully modular 80 PLUS Gold or Platinum rated PSU with multiple 12V-2x6 connectors or higher wattage ratings.

Pros

  • Includes a native 12V-2x6 connector with a dual-color design, supporting up to 450W for modern GPUs.
  • Backed by a 5-year warranty, providing extended coverage for the unit.
  • Features a 120mm Golf-blade fan for air cooling.
  • Offers 80 PLUS Bronze certification, indicating 85% efficiency at typical loads.
  • Comes with a full suite of protections including OCP, SCP, OVP, UVP, OTP, and OPP.

Cons

  • Non-modular design means all cables are permanently attached, making cable management more challenging.
  • Only includes one 12V-2x6 connector rated for 450W, which might be insufficient for some high-power GPUs.
  • Some Reddit users noted that it only comes with one dual PCIe 6+2 pin cable, which can be restrictive for certain GPU setups.
  • The product is listed as 'Not compatible with all built-in computers or systems' without specific details on incompatible systems.

Dimension Scores

Efficiency & Output5/10

The 80 PLUS Bronze certification is an entry-level efficiency rating, providing 85% efficiency at typical loads.

Noise Level6/10

It uses a 120mm Golf-blade fan, and some users describe it as 'quiet' in operation.

Build Quality5/10

The unit is manufactured by HEC (ODM) and is listed as B-tier on some PSU tier lists with 'limited confidence', suggesting average build quality for its price point.

Cable Management3/10

As a non-modular power supply, all cables are permanently attached, making cable routing and management more difficult, especially in smaller cases.

Best For

  • Budget-conscious PC builders needing PCIe 5.1 support for a single mid-range GPU.
  • Systems requiring a 750W power supply with a 5-year warranty.
  • Users who prioritize a native 12V-2x6 connector over modular cabling.

Not Recommended For

  • High-end PC builds with multiple or extremely power-hungry GPUs exceeding 450W on the 12V-2x6 connector.
  • Users who demand pristine cable management and prefer fully modular power supplies.
  • Small form factor cases where excess non-modular cables would severely restrict airflow or space.

Watch Out For

  • The 'Not compatible with all built-in computers or systems' warning is vague, potentially leading to unexpected compatibility issues.
  • Cable management can be difficult due to the non-modular design, leaving unused cables to be tucked away.
  • The single 12V-2x6 connector is limited to 450W, which might not be enough for some higher-tier GPUs that can draw more power.
  • Only one dual 6+2 pin PCIe cable is provided in addition to the 12V-2x6, limiting options for GPUs requiring multiple separate 8-pin connectors.

What Buyers Say

Users generally find this ASRock Challenger 750W PSU to be a dependable option for their PC builds, especially considering its price point. Many appreciate the inclusion of a native 12V-2x6 connector for newer GPUs and the 5-year warranty. The primary drawback mentioned is its non-modular design, which can complicate cable management, though some users don't see it as a deal-breaker. There are also comments about the limited number of separate PCIe cables for GPUs.

“Man, I needed a PSU for my new GPU with that 12V-2x6 plug, and this one had it without breaking the bank. The cables are a mess though, had to shove 'em everywhere, but hey, it works!”

Common Praise

  • Provides reliable performance for various PC configurations.
  • Includes a native 12V-2x6 connector for PCIe 5.1 GPUs.
  • The 5-year warranty offers peace of mind.
  • Operates quietly during use.
  • The dual-color design on the 12V-2x6 connector helps confirm proper seating.

Common Complaints

  • Non-modular design makes cable management a hassle.
  • Only one 12V-2x6 connector with a 450W limit.
  • Limited to one dual 6+2 pin PCIe cable for additional GPU power.
  • Vague compatibility warning about 'not compatible with all built-in computers or systems'.

Ownership Tips

  • The non-modular cables are stiff and can be tough to bend and route neatly behind the motherboard tray.
  • The 12V-2x6 cable's dual-color design is actually helpful for making sure it's fully seated, preventing potential issues.
  • The fan is barely audible under typical gaming loads, which is a plus for a budget unit.
  • You'll definitely want zip ties or Velcro straps ready for the unused cables to keep your case tidy and airflow clear.

Frequently Asked Questions

Buying Guide

When you're looking at a power supply like this, you're basically buying the heart of your PC. It converts wall power into usable power for all your components. The 'wattage' (750W here) tells you how much total power it can deliver, and '80 PLUS Bronze' is an efficiency rating, meaning less power is wasted as heat. Since this one is 'non-modular', all the cables are attached, which means you'll have extra cables to hide even if you don't use them all.

Alternatives

If this PSU doesn't fit, look for fully modular power supplies for easier cable management, or 80 PLUS Gold/Platinum rated units for higher efficiency. For very high-end GPUs, seek PSUs with higher wattage 12V-2x6 connectors or multiple dedicated 8-pin PCIe cables.
