Hi, I am thinking of building a PC myself, but, this is my first time and I am asking you - the community - for your opinions and thoughts about the components I am using. This PC is going to be used primarily for gaming, and maybe a bit of rendering. I want the things to last a couple of years without having to upgrade. Please can you tell me if there are any problems between any of the components or, if everything will work in perfect harmony.

Here are the components:

CPU - Intel Core i7 4770K
Motherboard - Asus Z87-Pro
Memory - Corsair Vengeance 16gb Low Profile Memory DDR3 (2x8)
Graphics Card - EVGA Nvidia GeForce GTX780 Superclocked ACX Cooler 3GB GDDR5
Power Supply - Corsair CX750 Builder Series
Storage - SSD - Samsung 840 EVO 120GB
HD - WD 1TB 3.5 inch Internal Hard Drive - Caviar Blue

The PSU is not good. Change it to an XFX, Antec, Seasonic unit.

Corsair does not build poor PSUs as the previous poster implies, although that series of Corsair's is not their best (nor most expensive). For quick recommendations, without knowing your budget, I'd recommend:

GTX 780 ti - a better match than the 780 to prevent performance bottlenecks with your CPU.
Corsair TX750 - a much more reliable power supply. Version 2 or modular also fine.
Samsung 840 Evo 250gb - you'll want the extra space to feel comfortable with how much you install.

The CX, CS, RM units are not very good. Average at very best. They use prro quality capacitors that fail easily under any real heat. This is a well known and documented issue. Stay away from these units. The Corsair units you want are the Seasonic OEM'd ones. AX, HX, TX.

I will probably buy that PSU then, but is the GTX 780 ti a lot more expensive than the 780? I don't want to spend too much money that will not dramatically improve the game.

A 780 will max all games at 1080p. It is definitely the card to get. I would not get the 780ti. It isn't worth the money right now especially if you are only playing at 1080p.

Ok, thanks for the advice. Also, is it safe to over clock the CPU. I heard you need liquid cooling to do this. Is it possible without liquid cooling?

No you do not need liquid cooling. There are air coolers that perform the same or better than the closed loop coolers on the market.

It's about $100 more. I personally don't think it's worth the extra money.

Corsair RM units aren't really that bad. There are some that are more reliable, but the RM series is still a Tier A power supply.

Ehh not really. They still use the EXACT SAME capacitors as the CX units and I have already seen one fail in spectacular fashion. I would not recommend them.

One of the computers in my house has been using a CX 430 to power an i5 and GTX 660 since the CX series was introduced (2010?), I've been using an RM 550 without a single problem for over a year now (which doesn't say much yet but still). In my experience the CX and RM series are both very reliable even though they use subpar capacitors. I've yet to have one fail on me.

The OLD first shipment CX430 was Seasonic OEM'd. The only of the CX line to be this way which changed after the V2 units shipped, where they were all CWT.

I had a cx600V2 fail in my personal computer a year ago.

Maybe I just have good luck with them then. I used a Liteon 300 watt power supply in my computer from 2000 until 2009 when I finally had to get a power supply with longer cables for a new case I had bought. My brother used a 330 watt raidmax for just as long without it failing, and my HTPC has been running a 500 watt Dynex for a little over 5 years now.

Bottom line: Corsair is decent, XFX, Antec, and Seasonic are excellent.

Some Corsair units are Excellent like the AX and HX units and some are barely average like the CX units. Plenty of companies have good and bad units.
