Default GTX 780 and Seasonic M12 600W

I have an old 460GTX and would like to upgrade it. I'm thinking of just going all the way and grabbing the GTX 780.

Looks like the GTX 780 needs 42A combined on the 12volt rails.

My PSU (Seasonic M12 600W) has 48 amps, combined.

Seems like I'd be cutting it pretty close, but I'd rather not upgrade my psu right now.

My gaming sessions can last up to 8 hours or so, on the weekend.

Anyone here think this is a recipe for disaster?

It'll work without issue. The 42 amps quoted are for the whole system, and even that's way overblown. The card alone won't draw more than 25A under any circumstance, excluding dry ice or liquid nitrogen/helium cooling. During normal usage (gaming - even heavy, not Furmark or folding@home), stock voltage and slight overclock, it shouldn't draw above 16-17A.

Thanks for the insight. Very good to know.

While browsing jonnyguru for a bit, I had a look at canadian prices and realised that the 780 is going for over $650 bucks here. Gulp. Think I might get a 770 or 760

Thanks again.

Also look at the 680/670, they got a big discount recently here, and are equivalent in power to the 770/760. I'm planning on grabbing a 670 as it's slightly cheaper than the similar powered 760.

Thanks. Unfortunately, here in Canada, the 680/670 can be more expensive than the 770/760. I'm not sure why that is.
