Lenovo ThinkStation P520: CPU TDP Compatibility
The Lenovo ThinkStation P520 supports a wide range of Intel Xeon W-series processors, but not all models can accommodate high TDP (Thermal Design Power) CPUs. Some systems are limited to lower TDP values, which may affect performance or upgrade options.
The TDP capability of a P520 system is determined by its model number, typically found on the label underneath the chassis. Identifying this correctly is important if you're upgrading the CPU or troubleshooting compatibility issues.
How to Identify the TDP Variant
To determine whether your system supports high or low TDP processors, locate the model number on the underside label. The machine type will begin with 30BF, followed by a model-specific code. Use the list below to identify the TDP category:
| Model Number | TDP Type |
|---|---|
| S44D00 | High TDP |
| S4NP00 | High TDP |
| S0NG17 | High TDP |
| S44D04 | High TDP |
| S0NG07 | High TDP |
| S44D0P | High TDP |
| SA9L00 | High TDP |
| S0NH0C | Low TDP (W-21 capped at 140W, W-22 capped at 120W) |
| S0NG01 | Low TDP |
| S0NH0S | Low TDP |
| S0NG02 | Low TDP |
If you're unsure which CPUs are compatible with your system, check the wattage rating of your current processor and compare it to the specifications of your intended upgrade.
