Okay

So my PSU (g650m) has 52A on the 12v rail. If a GPU requires 40A and a 500w PSU, can I use the GPU (Assuming case allows it) or are their more specs of the PSU i have to consider?

And can i run a titan? (theoretical)

I'm running
i5 6400
8gb ram
1 SSD


Thanks
 
P=IE and E=IR

P is power in watts, I is amps, E is voltage. R is resistance in Ohms. (You don't need the second formula but i thought i would include it as they are the two major ones. )

The Quality of the power supply and things like ripple matter too. Some really budget brands do not deliver what they claim on the sticker.
 


so is the psu i have good?
 


ty, what did you mean by "420" (giggle)

 


List the video card using 40A on a video card is very rare that's a 480 Watt video card.
They should never recomend a PSU for a video card they should just state the TDP of the card because they have no clue what the rest of the parts in your PC is.
 


so i can use any single gpu option?
