商品問答

What does the 80 Plus rating on this 500W unit mean for real-world efficiency?

The 80 Plus certification guarantees at least 80 percent efficiency at typical loads, reducing wasted heat and lowering electricity draw compared with non-rated supplies.

Which case mounting points and clearances does the 140mm fan design require?

It fits standard ATX mounting holes; the 140mm double ball bearing fan needs unrestricted rear or bottom ventilation so airflow is not blocked by cables or a tight mesh panel.

How do I connect the 20+4-pin and 4+4-pin cables without forcing the keyed pins?

Align the clip side of each connector with the motherboard socket latch, press straight down until the clip clicks, and verify the 6+2-pin PCIe plug splits cleanly if your graphics card needs only six pins.
