Will my power supply be enough?

Question

Iron

Hello, help me find out if the power supply is enough for me.
Now I have this:
Xeon 3220 2.4 ghz x4
ddr2 6gb RAM (samsung, and one bar know name)
550ti 1gb
Power supply 400w (Open Solution Company)
I want to install a 7870 2gb vidyuhu. Tell me enough power supply.

Answer 1

Look at the power supply table for the lines. You need a +12V line. There can be two of them - the power of the vidyuhi and the power of the drives. Roughly multiply the number in the column by 0.75 to account for Chinese efficiency. Add up the peak power of the card, the TDP of the processor (the maximum or typical power does not matter, because the heat is not taken from the ceiling), about 10W for each disk in the case and another 75W for the power supply of the motherboard (xs what will hang on PCIE, so we take the maximum) .
If the sum of the powers does not exceed the power of the PSU along the 12V line, then most likely it will pull the load.
