Worauf muss ich achten?
Protection Mechanisms A good power supply comes with several protection mechanisms to safeguard your components, including:
- Overvoltage Protection (OVP)
- Short Circuit Protection (SCP)
- Undervoltage Protection (UVP)
- Overtemperature Protection (OTP)
- Overload Protection (OPP)
- Overcurrent Protection (OCP)
These mechanisms are crucial to prevent damage to your PC components and increase the system’s longevity.
Efficiency Certification (80 PLUS) The 80 PLUS certification indicates the efficiency of the power supply, revealing how efficiently it converts electricity into usable power. The certification is divided into various tiers, including Titanium, Platinum, Gold, Silver, and Bronze. The graphic illustrates the minimum efficiency levels of these tiers at different loads. Higher tiers indicate better energy efficiency.
How many watts do I need?
Choosing the right wattage for your power supply is crucial. Here are some helpful tips:
-
Use a Power Supply Calculator: Utilize power supply calculators to determine the recommended wattage based on your system components. These tools take into account your processor, graphics card, hard drives, and other hardware.
-
Plan for Buffer: It’s advisable to add a small buffer to the calculated wattage. This provides room for peak loads or future hardware upgrades without overloading the power supply’s capacity.
-
Brand Recommendations: Brands like Corsair and Be Quiet have proven reliability and performance. Be Quiet even offers its own power supply calculator tailored to their products.
