After seeing Corsair HX 850 insanely priced. I finding it hard to decide the right PSU for my upcoming rig. What is the minimum power requirement for this rig?

1) Core i7 4770K
2) ASUS Z87 Pro or ASRock Z87 Extreme
3) GTX 760 or 770 or 7970GHz edition in future I might upgrade to next generation GPU or will go for SLI or X-Fire
4) 128GB SSD along with 2/4TB HDD
5) Corsair H80 or H80i water cooling.
6) I will game 2560 X 1600 or 1440 resolution.
 
A solid 750W PSU will be more than enough. Hell you could get away with a solid 650W if you're not aiming for extremely high overclocks.
 
Any quality 450W PSU will be more than enough, OC or not.

Missed that bit. In that case, you are right, 650W if there aren't the very top of the line cards and extreme overclocks involved.
 
Not extreme overclocking. But I will try to overclock 4770K to 4.5, I might overclock GPU as well. My aim is gaming at that high resolution. Anyways I will go for a 650W power supply from Corsair

Generally they're overpriced for the quality you're getting. Corsair's own TX line tends to be of better quality and not that much more than the GS series.
 
The GS PSUs are, as I understand it, CX units with more bling.
Step up to the TX platform if you like Corsair, they're at least good if not better.
 
I feel from what I have read on other forums and reviews that the TX line is definitely the way to go. I personally have never used one, I have mainly only used Antec PSU unites with no issues at all. I have not really seen anything on the GS line. I would stick with what is known, also with the PSU that is the lifeblood of the system, do you want the $29.99 blood transfusion or the $299.99 blood transfusion?
 
Spend the money on a GOOD PSU especially one with at least a 5 year warranty like Corsair and Antec. It only takes the 1 time to learn this hard lesson. Every brand has failures... Shit happens.

I think the others that mentioned 650w should be minimum are correct in doing so, although I think you could do fine with 550 or even 500, but why limit? If you shop around you'll find excellent deals on 650 and 750 all day long. ..and if not today, a sale will come along soon. Always does.

I've got an Antec HCP750 and a Corsair 750TX. Both have extremely stable voltages. Do I need 750w right now? no. Will I need 750w later? maybe. Never know.
 
I'd go 750 so you'll have some headroom for overclocks and such. Plus, most PSUs are most efficient around 50-60% load so by having a bigger unit, you'll be closer to that sweet spot.
 
Thank you I will go for Corsair TX series PSU. I mostly read in these forums people going for HX and AX series PSU, which are insanely priced.

What country do you live in? I ask because here in the U.S, the HX and AX have actually gone down in pricing. Also, don't forget that the HX and AX series are of higher quality and have modular cables. Hence the higher price.
 
And modular cables are soooooo nice. So worth it to me to pay extra for how much easier it makes for routing and not have a whole bunch of extra cables tucked away in every hidey-hole in my case.

This is true.

Also, if you're working with a smaller case, the TX cables are rigid as hell. And... there are many... Work the sata cables a little prior to connecting if you have more than one hdd. Those damn things don't want to flex easily at first. (This is a good thing) just makes things a bit annoying. I use Silverstone CP06 for my drives, though.

BUT, to keep true to my name, if you don't have the budget for H-AX, the TX is fine. Hell, it may even be the single most user reviewed PSU out there. Certainly no shortage on documentation...

Since you linked to the U.S Amazon.com website, I'm going to assume that you're in the U.S. Now dude, you must have a really warped sense of pricing because the pricing for the AX and HX PSUs in the U.S are pretty fair and are not insanely priced. This is odd coming from you since you're the one about to spend or have already spent $300+ on a CPU, $260 to $400 on a video card, and $200 on a motherboard.

Yet look at the price difference between the TX750 and the HX750: A mere $14 difference! Or the $150 AX750. A mere $44 difference. The $14 to $44 difference, as I noted earlier, gets you significantly higher quality, performance, AND modular cables.

So in other words, your statement that the HX and AX series are insanely priced is wrong. That is unless an extra $14 to $44 is insane pricing for you. Yet somehow a $200 motherboard isn't.

^ definitely listen to this guy.

Yeah, the TX may be cheaper, but only slightly. Trust me, modular is worth it. If you have a small or cramped case, it'll make your life soooo much easier. Plus, you won't have a huge wad of extra cables restricting air flow.

OK I will take your suggestion. Just one last question. These certifications Gold, Silver and Bronze. What difference does it makes on perfomance and efficiency? Can these PSU still be re-usable 3-4 years from now when I further upgrade the rig?

First and foremost, those certifications are practically worthless as it's ridiculously easy to cheat on those certifications. I'm not saying Corsair cheats but the certification itself just isn't useful.

Second, theoretically, the better the certification, the better the efficiency. As for performance, theoretically, a Gold PSU is going to have better performance than a Bronze PSU. However, that's not always the case and there have been some cases where a Bronze PSU will outperform a Gold PSU.

So for all intents and purposes, I wouldn't bother factoring in the 80PLus certification. In fact, HardOCP did an article about that just two years ago:

Yes those PSUs might be usable depending on whether or not you actually take care of that PSU (i.e compress air every once in a while) and the electrical situation in your home.

Can you provide me some tips to take care of PSU? How do you compress air from PSU?

Let me rephrase: Use a can of compressed air to blast dust out of the PSU every once in a while. Also, stick the PSU on a UPS.

Thank you I always do that while cleaning the whole PC. How many of you have used these same Corsair PSU with 2-3 upgrades? I just like the way if you a good case it can last for couple of upgrades
 
I would say go no less than a 450W power supply. People always try to skimp on the PS and forget it is the backbone of their system. I have always felt that it is worth buying a little more than I may need today to allow for upgrading of components.
 
If now you're question is longevity, then I refer to a previous post I made and check the length of the warranty. Again, Corsair has a long warranty that will last the amount of years you specified. Shit happens... There's not a single person alive that can tell you if this or that PSU will not die on you. This is why you go with a reputable company that has gleaming reviews concerning RMA process. I can testify to Antec as I personally went through an RMA with them and was extremely pleased. My Corsair hasn't gave any cause (knock on wood) to experience (personally) their RMA process, although I have read hundreds of great reviews from others that have.

Corsair AX 7 years limited

Corsair HX 7 years limited

Corsair TX 5 years limited

That is the reason I am not looking for any other vendor except for Corsair and Seasonic. Another big concern is the change in CPU / mobo architecture which might make PSUs obsolete. For example the volage settings of current Haswell has made all the previous generation PSUs obsolete

Yeah that's very misleading:
Haswell's C7 sleep state is optional and disabled by default. As such, unless you actually enable said sleep state, Haswell has not made all previous generation PSUs obsolete. If you do enable that sleep state, mainly poorly designed/built group-regulated PSU designs and/or just shitty PSU designs in general will have issues with that sleep state. In other words, if you buy a good PSU, you don't have to worry about that C7 sleep state in the first place.
 
+1 for modular psu in small cases. You won't have any room for the air to move if the cables are blocking the wind movements.
 
I opted for the TX650M, I'm not quite sure why everyone is suggesting to bump up to the AX/HX simply because they are modular. I can understand if you wanted to spend more based on the gold cert. or other factors but the TX650M is modular and can be had for around $90 w/ rebate.
