| Field | Value | Meaning | |-------|-------|---------| | Model | ATX-600W | Often misleading (peak rating) | | | 46A | Most important real current | | Combined +12V Wattage | 552W | True continuous wattage | | AC Input | 100-240V~ | Auto-switching |
Ignore the large “600W” marketing number. Find the smaller “ +12V Combined Power ” or “ Max Continuous Power ” value. If a PSU advertises 600W but +12V is only 400W, it is a low-quality unit. 4. Method 2: Software Estimation (Indirect) Limitations: Software cannot read the PSU label; it can only estimate power draw or read OEM info from specific laptops.
