FAQs
What is 80 PLUS Gold certification?
80 PLUS Gold certification indicates that the power supply is highly energy efficient, typically operating at 87-90% efficiency at various load levels. This means less energy is wasted as heat, saving on electricity costs and reducing thermal load inside your PC.
What does ATX 3.1 and PCIe 5.1 support mean?
ATX 3.1 is the latest standard for power supplies, designed to better handle the high power excursions of modern components. PCIe 5.1 support, often indicated by a 12V-2x6 connector, means the PSU is ready for the latest generation of graphics cards that require these new power specifications.
Is the 12V-2x6 connector the same as the 12VHPWR connector?
The 12V-2x6 connector is an updated and safer version of the 12VHPWR connector. It's designed to ensure a more secure connection and better thermal performance, offering improved reliability for high-power GPUs.
What is the 5V BOOST function?
The 5V BOOST function is a feature that ensures consistent and stable voltage delivery on the 5V rail. This is particularly important for peripherals connected via USB and for solid-state drives (SSDs) that rely on stable 5V power.
How do I clean my power supply?
To clean the power supply, first ensure the PC is turned off and unplugged. Use compressed air to blow dust out of the PSU vents. You can also gently wipe the exterior with a dry or slightly damp cloth. Never open the PSU casing.
What is the warranty period?
The ASRock Challenger 850W PSU comes with a 5-Year manufacturer warranty, providing comprehensive coverage for potential defects.
Can I use this PSU in a smaller ITX case?
While the PSU adheres to the ATX form factor, its non-modular design means cable management can be challenging in very compact ITX cases. Ensure the case has adequate space for the PSU and its cables for proper airflow and installation.
Troubleshooting
PSU not powering on
Verify the power cord is securely plugged into both the PSU and the wall outlet. Ensure the PSU switch is in the 'I' (on) position. Test with a different wall outlet. Check if all internal power cables are correctly seated on the motherboard and components.
System randomly shutting down or restarting
This could indicate the PSU is overloaded or failing. Ensure your system's power consumption does not exceed 850W. Check that all PSU cables are firmly connected. Clean any dust buildup from the PSU fan and vents to ensure proper cooling.
Noisy fan operation
A slight fan noise under heavy load is normal. If the noise is excessive or rattling, check for obstructions near the fan. Ensure the PSU is securely mounted. If the noise persists, contact support as the fan may need replacement.
Components not receiving power (e.g., GPU, drives)
Double-check that the specific power cables for those components are correctly connected to both the PSU and the device. Ensure you are using the correct cables (e.g., PCIe for GPU, SATA for drives).
Pros and Cons
Pros
- High 850W power output suitable for demanding systems.
- Excellent 80 PLUS Gold efficiency reduces wasted energy and heat.
- ATX 3.1 and PCIe 5.1 readiness ensures compatibility with modern GPUs.
- Reliable components like 100% Taiwanese capacitors enhance durability.
- 5-Year manufacturer warranty provides long-term peace of mind.
Cons
- Non-modular design can make cable management more challenging in tight spaces.
- May be overkill for budget or low-power builds.
- Fan noise might be noticeable under very heavy sustained loads, though generally quiet.
Setup, Compatibility & Care
Setup:
- Ensure the PC is powered off and unplugged from the wall.
- Open the PC case and locate the PSU mounting space.
- Secure the PSU using the provided screws.
- Connect the necessary power cables to the motherboard (24-pin ATX, 8-pin EPS/CPU), GPU (PCIe 6+2 pin or 12V-2x6), and storage devices (SATA).
- Connect the PSU to the wall outlet using the provided power cord.
- Manage cables neatly to ensure good airflow within the case.
Compatibility:
- Form Factor: ATX standard, compatible with most ATX, EATX, Micro-ATX, and Mini-ITX cases that have standard PSU mounting.
- Motherboards: Supports standard ATX power connectors (20+4 pin).
- CPUs: Compatible with all Intel and AMD CPUs requiring 4-pin or 8-pin EPS power connectors.
- GPUs: Supports PCIe 5.1 via the 12V-2x6 connector and traditional PCIe 6+2 pin connectors for a wide range of graphics cards.
- Storage: Standard SATA power connectors for HDDs and SSDs.
Care:
- Keep the PSU vents clear of dust and obstructions. Periodically clean the exterior with a dry or slightly damp cloth.
- Avoid placing the PC in environments with excessive dust, humidity, or extreme temperatures.
- Do not attempt to open the PSU casing; internal components are dangerous.
