Compatibility

Information on Mobile Pentium III 450 compatibility with other computer components and devices: motherboard (look for socket type), power supply unit (look for power consumption) etc. Useful when planning a future computer configuration or upgrading an existing one. Note that power consumption of some processors can well exceed their nominal TDP, even without overclocking. Some can even double their declared thermals given that the motherboard allows to tune the CPU power parameters.

Number of CPUs in a configuration	1	of 8 (Opteron 842)
Socket	495
Power consumption (TDP)	15 Watt	of 400 Watt (Xeon Platinum 9282)
