Four-pin, eight-pin, and twelve-pin connectors available.
Four-pin, eight-pin, and twelve-pin connectors available.
You need to upgrade your power supply to support the 8+4 pin CPU connector. The PSU you have is only compatible with a 4 pin connection, so you'll need a PSU that matches the 8+4 pin CPU socket.
Review the instructions carefully; they specify the next steps.
Usually the additional four-pin connector is not required and is meant for boosting performance. You’ll likely need to replace the eight-pin slot with at least one, and it’s important to check if your power supply can handle it before purchasing the motherboard.
It would work with only the four-pin connector. Yet… what scenario matters? 450 watts isn’t huge, right? A GPU might be needed. If the CPU gets strained, you should use a power supply with an eight-pin as the maximum load it can handle. In short, avoid drawing too much power through the cables since resistance increases and efficiency drops, which can lead to problems.
Choose the 4 pin CPU connector if available. It fits into one half of the 8 pin connector—plug and connector must match the keyed design. You might find it works in either position, but it’s fine. The 8 pin is preferred since some boards won’t power on without it. A 4 pin cable handles about 190 watts, while an 8 pin supports around 320 watts. A Core i5 11400 uses roughly 80-100 watts, so the 4 pin should suffice. More cables reduce current per wire, lowering heat and offering room for overclocking. Some systems include an extra 4 pin for extreme overclocking. If you're cautious, adapters exist to convert between PCIe 6, 8, or older connectors. Ensure your power supply can deliver sufficient 12V—multiply the listed wattage by 12. Most models provide at least 320-350 watts on 12V (about 29A), which covers the needs.
