Hi,

I currently have an Antec TruePower New TP-650 PSU with ouputs of +3.3V@25A, +5V@25A, +12V1@22A, +12V2@22A, +12V3@25A, +12V4@25A, -12V@0.8A, +5VSB@3.0A. According to EVGA 560 Ti, it requires 500 Watt or greater power supply (Minimum recommended power supply with +12 Volt current rating of 30 Amps.).

The problem here is, my max 1 rail 12 V is only 25 A, and the gphx card recommends 30 Amps. I am assuming the gphx card probably wont take up all 30 A because P=IV and 30A*12V =360 W, which is quite ridiculous but I could be wrong. Anyways, do you guys think the current Amps I have is sufficient?

Many thanks in advance!

The amps don't have to come from a single rail ( and won't ), they reccomend that your psu have a total 12v output of 30a.
If it will make you more comfortable, the actual OCP trip point is 40a

Nothing to worry about.

I am no computer enthusiast and I am very confused. Out of curiosity, if the amps don't come from a specific rail, then what is the point of the multi-rail? Isn't to prevent the whole system from frying instead of like a specific part?

If they recommend that the PSU to have a total 12v output of 30a, are you implying that the amps are additive?
I thought you can't add amps coming from other rails so that it can exceed 30amps?
