Netzteilkompatibilität

Netzteilkompatibilität refers to the ability of a power supply unit (PSU) to work correctly with all the components in a computer system. This is a crucial aspect of PC building and upgrades, as an incompatible PSU can lead to system instability, component damage, or failure to boot.

Several factors contribute to Netzteilkompatibilität. The most important is the wattage, which is the maximum amount of power the PSU can deliver. This wattage must be sufficient to meet the combined power demands of all components, including the CPU, GPU, motherboard, storage drives, and peripherals. Manufacturers often provide recommended PSU wattages for their components, and it's advisable to choose a PSU with some headroom to ensure stable operation and accommodate future upgrades.

Another key aspect is the connectors. PSUs come with various cables and connectors for different components. The motherboard requires a primary power connector (typically 20+4 pin ATX), and the CPU needs a separate connector (4-pin or 8-pin EPS). Graphics cards often require PCIe power connectors (6-pin or 8-pin). Storage devices like HDDs and SSDs use SATA power connectors. Ensuring the PSU has the correct and sufficient number of these connectors is essential.

Form factor is also relevant. The PSU must physically fit into the computer case. The most common form factor is ATX, but smaller cases may require SFX or other compact PSUs.

Finally, efficiency ratings (like 80 Plus Bronze, Silver, Gold, Platinum, Titanium) indicate how effectively the PSU converts AC power from the wall to DC power for the components. While not strictly a compatibility issue, a more efficient PSU generates less heat, runs quieter, and can slightly reduce electricity consumption. While not a direct compatibility concern, choosing a PSU with an appropriate efficiency rating is generally recommended for better overall system performance and longevity.
