How to know what PSU to get according to GPU?

How to know how many watts PSU should you get according to the GPU?
For example if the gpu would be:

That's a CPU or a processor, not a GPU (graphics processing unit).

CPU's are usually not an issue when choosing a PSU, there are of course some exceptions but generally speaking, it just doesn't matter. Any low end ATX unit can power any processor.

Oh i missmatched, i wanted to show gpu, and i showed cpu, my bad
So for example what PSU should you get if you have AMD FX 8350 GPU?
And how to know how many watts do i need?

just post your entire system specs CPU/GPU harddrives etc. then we'll help you choose a PSU.

The Intel i7-4750HQ is a notebook CPU and the AMD FX-8350 is still a CPU and not a GPU....

okay forget this, the main question stays: how to know how many watts PSU you need?

In an average consumer PC, any PSU that has the necessary PCIe connector configuration for your graphics card (or several graphics cards), is powerful enough. To know this you will need to check the specs of both your graphics card and your power supply. E.g. for a GTX 770 2GB graphics card you typically need a 6-pin and an 8-pin PCIe connector. These are typically found in good quality 500 Watt units.

If you use integrated graphics, any PSU wattage is probably enough.

More important than wattage, however, is your power supply's quality (~ stability and reliability all the way up to its rated wattage output). Just because a unit says it's 500 watt doesn't make it equally powerful and equally reliable as another 500 watt unit from a different manufacturer. Always read a review from a trusted site (Anandtech, Techpowerup, Hardwaresecrets, JonnyGuru and HardOCP, among others) or at least have some informed opinion before making a PSU purchase.

Finally, the question "what PSU do I need" is a bit different from the question "how much power does my system consume". If you want to know the latter, you can estimate it by looking at power consumption readings for a system that has the graphics card you're planning to use. E.g. Guru3D's graphics card reviews.

okay thanks, another question - does all laptops have integrated gpu's? If not how can i now if it's integrated or dedicated?
And the same question goes for desktop pc's
how to know if it's integrated or not?

 

[lehtv]

No, not all laptops have integrated graphics.

Intel GPUs are all integrated in the CPU, NVIDIA GPUs are all dedicated, and AMD has both dedicated and integrated GPUs. In the past, NVIDIA also made integrated GPUs but dropped from that business since GPUs became integrated in CPUs which NVIDIA doesn't manufacture.

Not sure about laptops, but on desktops, AMD's integrated GPUs end in a D while dedicated GPUs lack this suffix. Googling the model number of the GPU should be an easy way to confirm if it's integrated or dedicated.

thanks! useful information! and if it ends with "M" its mobile for laptops? also integrated?

 

[lehtv]

Ending in M = mobile dedicated. Integrated mobile GPUs from AMD end in G, if I'm not mistaken

thank you very much
