My home power supply max 250W graphics card is GT240 I want to swap my AMD Athlon 2 4000 for 5800

AMD Athlon X2 5800+TDP: 89W AMD Athlon X2 6000+TDP: 125W

The maximum power supply of 250W is not enough, the rated 250W is barely on 5800+, and the rated 300W is barely on 6000+,

4000 65W 5800 89W 6000 125W It is recommended to increase the power supply by more than 300W.

It can be used, 2200g itself is not very power-consuming, 250w power supply is completely enough to bring up 2200g, choose power supply according to your own hardware, do not choose miscellaneous power supply.

Each CPU needs a different voltage, choose a suitable power supply for your computer, the power supply does not need to be particularly large, unless the power consumption of other hardware of your computer is very high, so you need a power supply with high power.

Enough of course. The R3 2200G itself does not consume electricity. But if you want to set up an HTPC, you may need a small chassis and a small motherboard, and you may need to spend more money in this regard.

2200G itself has low power consumption, as long as there is no external graphics card, it is enough.

The 180W power supply is not quite suitable for the GT240.

GT240 graphics card TDP is 65W, processor TDP is also 65W, a total of 130W TDP, TDP itself is thermal power is not necessarily equal to full load actual power, the actual power may exceed TDP, in addition to the power supply also needs to supply power to other hardware in the computer, such as motherboard, hard disk, memory, etc. The total power consumption is about 30W, a total of about 160W, at this time, the use of 180W power supply is not very stable, Generally, such a configuration is recommended to use a regular brand power supply rated at least 250W and above.

As for whether it can be used, you can actually try it, if the computer does not restart, you can continue to use it, if there is the above unstable situation, then you have to consider changing a power supply, now rated 300W ordinary power supply is about 140 yuan can be bought.

Some power supply manufacturers have a nominal higher power than the actual one, and the moisture is larger;

The power labeling of some power supply manufacturers is relatively conservative, and the nominal is basically the same as the reality, or even lower than the actual one.

If the actual effect of the power supply can reach 250W, it should also be able to be used.

If there is moisture in the nominal area, it is a bit overhanging.

If the difference is not big, you can buy a larger one, insurance.

Or ask the seller, if he can guarantee that he can, let him write on the receipt, and ask him to exchange or return it if it doesn't work.

There is a big improvement, but the current host configuration is not able to give full play to the full performance of the GT240, and the power supply can drive.

Let's change it to a 220.

Because your CPU is not high, the memory should be DDR2, and you don't need to change the power supply if it is rated at 250W.

The difference in graphics card performance is worlds apart, and the power supply doesn't need to be changed as long as it's not overclocked.
