Reicht mein 550W netzteil?

Hello

Whether the power supply is sufficient or not, can be calculated relatively easily approximately.

The Ryzen 7 7800X3D processor also takes up to 162 PPT, according to the factory specification 120W TDP, with it essentially remaining because an X3D processor cannot be additionally overclocked since AMD has blocked the overclocking for these processors because of heat problems at the L3 cache.

The RTX 4060 graphics card also needs up to 115W, according to the factory specification, and tests have shown that in some games were burned up to a little over 130W.

The rest in such a PC can be calculated with 30W to 60W, depending on the equipment. Only with an extreme equipment, with multiple hard drives and a lot of RGB lighting, the power consumption can still be a little higher.

CPU max. 162W + GPU max. 140W + remainder max. 60W = max. 362W

The PC will burn between 350W and 400W under full load. This is not a problem for a good 550W power supply. There is still a reserve between 150W and almost 200W.

However, it should be a power supply that can be permanently loaded with up to 550W. Many low-cost power supplies that are specified with 550W load capacity, but can only catch short load peaks up to 550W, but the long-term load capacity is then clearly below, with often only 400W. With such a power supply could then become somewhat narrow.

A good 550W power supply can be seen at the manufacturer and the exact model when you know. Power supplies from BeQuiet, Corsair, Seasonic and Sharkoon as well as some models from AZZA, Chieftec, FSP and Kolink are relatively usable.

A good power supply is often not visible, which is good, but a bad 550W power supply is relatively easy to recognize.

However, if there is no or only an 8(6+2) terminal PCIe plug on a 550W power supply to connect a graphics card, then this indicates that the manufacturer does not want the power supply to be too heavily loaded with a correspondingly strong graphics card, although a 550W power supply should normally also be sufficient for many graphics cards with more than an 8(6+2) terminal PCIe connection.

Even if there’s something from 550W Peak Power on the power supply, then look closely again, because often there’s something smaller printed, which is from 400W combined, continuous, steady, or constantly power, and this then indicates the actual load capacity of the power supply.

A good 550W power supply is, on the other hand, more durable, which is why at least two 8(6+2) pole PCIe connectors are connected to it, for correspondingly strong graphics cards. This is not an accurate science now, but a layman can be roughly orientated.

PS: Better take a less powerful AM5 processor like the Ryzen 5 7500F and buy you a better graphics card from the saved one. Of these, games have more than a strong processor and a relatively weak graphics card. However, a new power supply may also be due.
