Hi

I am looking for a wee bit of advice. Regarding my psu.

I have a Delta Electronics 460w psu. The sticker says. Output 12v A 15.5A, 12v B 11A and then another max 12v 31.5A I am just wondering as I just want to make sure my psu can handle the graphics card that I am planning to get. Nvidia GT 640 i know it has more than enough watts but it says it requires 20A on the 12v rail. I have no other pci devices connected to the computer.

Yes - 31.5a is more than enough. One thing is confusing to me tho, is there
a 3rd 12v rail? Your 31.5a max is greater than A+B, should be less if
there are 2 12v rails. I suspect there is a 3rd.

Could you post the model #. I would like to check the specs.

Hi thanks for getting back to me.

I was thinking it was enough but wanted a 2nd opinion.

just checked the label again.

their is a 12v CPU @ 15A as well

it is a Delta Electronics DPS-460CB C REV :01 F

Ah - OK, makes a lot more sense. The CPU runs off +12v rail.
You still have max 31.5a +12v rails.
