Can I overclock my rig?

post #1 of 9
Thread Starter 
Hi there. I'm brand new to the forums so hello. biggrin.gif

I actually joined because this forum looks like the perfect place to ask this question.


Anyway, I just recently built myself a gaming rig for the first time this past Monday. My system specs are as follows:

Case: Corsair Carbide Series 200r

Motherboard: MSI Z77A-G45

Processor: Intel Core i7 3770k Ivy Bridge

Graphics Card: MSI Twin Frozr AMD Radeon HD6950 2GB (w/ unlocked 6970 shaders, according to previous owner)

CPU Cooler: Cooler Master Hyper 212 Plus

RAM: Kingston HyperX Blu DDR3 1333 8gb (2x 4gb)

Power Supply: Corsair CX600 (600 watts, obviously)


So I basically want to overclock my CPU and possibly even my GPU. Not to the absolute maximum, but enough to get a decent boost. All I want to know is if this is even possible with my current power supply. I'm not all that familiar with power consumption and whatnot. I know there are PSU calculators out there that I could use to get a rough estimate on how much power my system eats, but I don't feel like they're reliable enough. Regardless, after using the eXtreme Power Supply Calculator, the recommended wattage came out at 548 watts (minimum 498). That's with 30% capacitor aging since I'll be using this PC for a lot of gaming.

If anyone could help me out here, I'd greatly appreciate it.

you'll be fine and dandy with that PSU. Power needs are exaggerated.

Really? That's good to hear. I'll have to get on that then.

Thanks for the info. I appreciate it.

Yeah I used that and it said it recommends at least 548 watts and a minimum of 498. That's with 30% capacitor aging since I game a lot. Not sure if I shot too high with the percentage or not.

I don't think you really need to factor that in. I've got a 5 year old PSU that's still going strong lol

Should be alright. I have that same board but with a i5 2500k. Running at 4.5 with vcore of 1.3. The best way to overclock on this board is the turbo overclock. Let me know and i will help if i can. Here isa thread where it has some screen shots of the bios to show somewhat how to do it if you don't know already. Psu should be good

That PSU is quite appropriate for the hardware set.
480W on the 12V rail is kinda perfect, really.

I certainly wouldn't expect aging to affect a good quality unit so badly, either.

In a word: yes. wink.gif

That 30% estimate for cap aging is probably a little aggressive and gives you some overhead too while your caps are young. Your needed power is probably near the minimum. Even a 20% OC on the i7 should only bump your power draw by 40-50W.
