Will my 520w be enough?

You really might be cutting it close considering the power requirements of that CPU. IF anything another 100W on that PSU should put you over the worry-limit. 🙂

Congrats on the build!

The Real Power M520 outputs 408W on the +12v rail and is fairly solid so you'll be fine. Your CPU and GPU combined peak at only 276W so games won't even make them draw that much power, and you have plenty of wattage left for the rest of the system.

You two just gave me two different answers o_O. Didn't really make the choice easier.
I kinda feel like Jester knows more what he is talking about. No offense Strud

Oh and Jester. I have overclocked my 5850 to max with the driver control panel. Don't know how much that effects it.

Thank you! Bin waiting a long time to get away from that Athlon CPU 🙂

With the headroom you had leftover you should be fine with that GPU overclock.

I'm gonna regret this when bulldozer comes -.-
But then I probably would need a new mobo, and I think the 1100t will be good a really long time

Games hardly utilize more than two cores these days so for games it will be fine. Of course when you update your motherboard Intel is the way to go... not favoring brands it's just that their products produce better overall results and they use a 32nm process unlike AMD. The Intel Core i5 2500k for example outperforms the 1100T in nearly every application, it only has a 95W TDP instead of the 1100T's 125W and it can be overclocked past 5 GHz on air quite easily. I don't even think they consider it to be an "enthusiast" CPU...

I get around 540W
combined

Edit: didn't see your last post. I use my setup to stream while gaming. So it will use several cores.

Your 540W figure comes from two whole computers - one with an 1100T and some GPU and the other with a 5850 and some other CPU and hardware. The 1100T has a 125W TDP (the power consumption peaks at about this) while the 5850 has a rated power draw of 151W peak.

Darn, you are right. I noticed that too
