Will my bp pull on a 400w rx 470 4gb graphics card?

You can reduce your energy consumption in the driver settings.

The comp can be disconnected at high loads. And the power supply for 8 years can give is not 400W.

If, for example, reduce consumption from 120w to 100w or even less, should at least normally start the game - the limit of 45 phps will be on the average settings in games?

Cougar VTE600W - less noisy
Or something cheaper but that the parts were 80' Bronze minimum
Now the assemblies are very substandard. It's better not to save

The lifespan of BP is 7-8 years. Then there is wear, drying of capacitors, etc.
Cheap, noisy, fake without quality parts can die in 1 year.
To steal other details

No one's going to tell you for sure. I have a friend at the time changed the map from Geforde 560gt to Amd r9 390. It had a minimum unit at 650w. In short, how lucky. It is better to really dig up and take at once a normal block, not worried about the rest of the components as already written above.

No one can guarantee it - depends on the power supply itself and what will happen to the network (voltage jumps, frequent outages, etc.). It is better not to take risks - if something burns down (especially the new video card), the savings on the BP will not justify itself.
Spoiler To me the former BP 500 W worked for more than 9 years, then suddenly tensions flew off all the lines.


Well though the defense worked and nothing burned - the system loaded, and then brought out a message about problems with the problem.
