Hello, I was wondering if an Antec Earthwatts 650w 80+bronze was enough power for this system:

CPU: Intel i7 2600k w/ Cooler Master Hyper Cooler 212 Plus
Board: ASUS P8Z68-V/GEN3
RAM: 2x Corsair Vengeance 4GB DDR3 1600MHz
GPU: XFX Radeon 6870
HDD: Hitachi 1TB 7200rpm 3GB/s
OS: Windows 7 Home Premium 64bit

Best solution

Yes, more than enough. A good 550W unit would be plenty for that system. AMD only recommends a 500W PSU for the 6870, anyway.

Thanks DJ, now i don't have to go waste money on some extra fluff. By the way, sometimes when i load skyrim my system will start to stutter and the sound will cut in and out. Do you have any idea what this is from?

Not really sure on that one, to be honest. Could be a driver issue.

Ok I'll check that. If I added another 6870, would I need a higher wattage unit? Maybe a 750? And would i need more cooling or would the two case fans and gpu fans be enough?

AMD recommends a 600W PSU for Crossfire 6870's, but I'd go with a good 650W unit (like that Antec), personally (for overclocking headroom, etc.).

Cooling shouldn't really be a huge problem, but more airflow never hurts.

Testing 1,2,3 how did you get your cpu to overclock so high?

Are you talking about how I got CPU-Z to show my OC? I just used the High Performance power plan in Windows to lock in max speed and keep it from idling while I Validated.

Oh gotcha, yeah that makes sense now. If it stayed that high all the time i'd burn out right? On the AI Suite II software, would you recommend hitting the extreme turbo boost option for my system or just the fast option?

It won't necessarily "burn out" (although it will decrease the lifespan by a small margin, if OC'd because of higher voltage. It won't at stock, though, since that's just max Turbo which it can handle easily). There's just not much reason to leave it that way 24/7, unless you really need it (like when you're gaming).

As far as AI Suite goes, don't mess with it. Just OC manually through the BIOS. Software/Auto OC's are evil, lol (too much voltage and plenty of other issues to go with it).
