My present is Intel 2140 @ 1.60GHzWant to change a Intel Pentium Dual Core E5300 (box), need to change the power supply? And chassis fans?My current power supply is about 220W
If you don't have the computer running full load, you don't have to change the power supply. But want to stable operation, or change 300W power is better
No, but if you plug in another card, 220W might be a bit low.For dual core CPU, recommend 300W.
Don't change it. It should be enough.Computer host standby power 50W in general (excluding graphics), according to your configuration, you should not have a high-power display card, so 220W can still withstand.
If you just change a CPU, is not used at all for power, but if the cards should carefully consider upgrading some of the 4670 cards with 220W rated some dangerous, long-term power supply to the full load operation may damage the power supply and computer motherboards and other important elements. Consider replacing 300W or 350W power supplies (brand ratings), such as big horse drawn cars.
When the computer upgrades CPU, do you want to upgrade the power, depending on the situation?.1, the general computer power supply has at least 50W of the surplus, so if you upgrade the CPU core did not increase, but the main frequency is higher. For example, dual core low frequency upgrade, dual core high frequency, then the power can not be changed, the premise is absolutely no overclocking.2, if the upgrade of the CPU increased the core, such as dual core, quad core upgrade. When the power supply demand increased significantly, not only to consider the power supply is enough, but also to consider the motherboard power supply is enough, such as the two-phase power supply three-phase power supply or motherboard may appear insufficient power supply, even if your power is great, but the motherboard power supply shortage, still not.
