Is this PSU sufficient

[SlippingRelic]

So I'm thinking of overclocking my CPU when I build my system and maybe, and that's a big maybe, my GPU. My power supply is a Seasonic SSR-550RM 550 watt 80+ gold. So I'm wondering if my PSU is sufficient enough for overclocking both or just one. If just one, which one would be better to overclock for everyday use, and which one for gaming.

Link to build: http://pcpartpicker.com/p/FBDzdC; I know some of you are going to say "you can't overclock with a stock, you have to get an aftermarket." To those I say, I know and I am still looking, so please don't pester me about it. One more thing, do any of you have the Be Quiet Pure Rock CPU air cooler. Is it any good, and how does it compare to the Cooler Master Hyper 212 Evo (in terms of temperature cooling performance, and build quality), is it better worse.

I know these are a lot of questions to answer, however, your responses will be taken seriously and that I can assure you of. Thanks in advance and have a good day; I'll looking forward to your answers!

Seasonic is a very good brand, and 500w is sufficient for a normal GTX970.
However the windforce is heavily overclocked and needs both a 6 and a 8 pin connector so you need close to that 550w.
Since the psu has two 6+8 leads, you should be fine.
I would not expect much out of a more aggressive OC.
Looking at the negative newegg reviews, I see some coil whine issues.

You might look at other versions.

Yes, you CAN oc with the stock intel cooler, at least up to a point.
I would buy either of the two CPU coolers because their 120mm fans will be much quieter under load.
We make much of minor differences in coolers, but pay little attention.

You have plenty of room to overclock. In my experience over clocking generally only increases power consumption by about 10%. Based on what I've measured on my 4690K \ GTX 760 (which draws more power than a 970), you'll draw less than 300 watts at full load. Mine at stock clocks only draws 249 watts at full load (measured from the wall so the PC is actually drawing less)

Can't say anything about the heat sink, but the EVO 212 works well for my 4690K. I did end up lapping it and that was worth 5 degrees alone.

I have become a bit jaded on the subject of haswell cooling for overclocking.
How high you can OC is firstly determined by your luck in the bin lottery.
I had high expectations from the Devil's canyon parts and their better thermals.
I found out that the thermals really do not matter unless, perhaps, you are a competitive overclocker.
Haswell runs quite cool, that is, until you raise the voltage past 1.25v or so.
Once you go past 1.3v, then you really do need very good cooling to keep stress loads under say 85c.
But, the consensus is that voltages higher than 1.30 are not a good thing for 24/7 usage.
I have been unable to find any official Intel recommendation on what is a safe vcore limit.
Even if you can handle the heat, how much do you really need that extra multiplier from say 4.4 to 4.6?
My thought is that it is better to use the exotic cooling funds for a quieter and less expensive air cooler.
I suggest a good tower air cooler like noctua or phanteks with 120/140mm fans.

The Seasonic SSR-550RM is more than sufficient to handle overclocking of both the CPU and the GPU.

Isn't there something like you should never use more 80% of what your PSU is capable of? And like your PSU is most effeicient at around 60% load, the efficiency of a powersupply has nothing to do with what it outputs like "currupted power" if that's even a thing, which supplies your components with "bad power", right? Sorry for the nooby questions, what can I say I'm a noob.

1. A psu will use only the power demanded of it, regardless of the max capability.

2. Quality matters. A cheap psu may lie about its power, or it may deliver watts on other than 12v where it is needed.
A cheap psu will state the maximum capability, not the steady state output. There may be no reserve capability.
A cheap psu will deliver power at room temperature, not the 50c. you will find in a case,
A cheap psu will not deliver consistent voltages; particular at max output.
Most importantly of all, a cheap psu will not have sufficient protective circuitry to keep from damaging all your parts if it fails under load.
3. Yes, generally, a psu is most efficient in the middle third of its range. A 20% overprovision is not a bad thing.
Bottom line----------------------------------------
Buy a tier 1 or 2 unit if you can.
here is one list:

So PSU is good for overclocking CPU and I don't need to change it; and I can possibly overclock the GPU right?

Right.

Okay then, thanks everybody for you help, it has been greatly appreciated! If you someone still wants to post something about the topic, I'm all ears and once again thanks and have a good day!
