Any cons of too much power???

Okay so yesterday I ordered parts for a new build and I got a PC Power & Cooling Silencer MK II 950w psu but all I will only have an i5-2500k and one gtx 560 ti for right now but will get another for sli soon. So all I wanted to know is if my system will only use about 640w or so with two gtx 560 ti's (I got that calculated wattage from newegg's psu calculator) will there be any cons for having such a large power supply when a lot less is required?

Not really, especially once you go SLI. Before you do, it'll just be a good bit less efficient than it should be because you won't be running it anywhere near where it's at its most efficient. Other than that, nothing to be concerned about.

Not really as it stillĀ is efficient when operating at lower loads.

The only con is the higher price tag, which isn't a big deal, and you seem to be ok with it, so go for it!

Your wallet will be thinner than if you went with a 750-850W PSU.

Yeah okay thank god! There was a 750w one but I wanted to be sure plus the 950w one was only like $10 more so I was like might as well get 200 more watts lol

Can you tell me what you would rate my build on a scale of 1-10?

This is for gaming if you couldn't tell :p 

Specs:
CPU: i5-2500k
GPU: GTX 560 ti superclocked
RAM: 8gb Kingston HyperX 1600MHz
PSU: PC Power & Cooling Silencer MK II 950w
MOBO: Gigabyte GA-Z68A-D3H-B3
HDD: Western Digital Caviar Blue 500gb
Case: NZXT Gamma Classic Series

somewhere between a 7.5 and an 8.5. main reasons are that no solid state drive and that graphics card is great and everything but i cant give you a 9 or higher because there are graphics cards such as the gtx 670/680/690 that are insane but thats a really nice build i have an i5 3570k, gtx 570, 8gb g.skill 1600mhz asrock z77 pro3, 1tb wd caviar blue, 128gb samsung 830 ssd, 700 watt psu, corsair h60 liquid cpu cooler and an nzxt phantom 410 mid tower case with many shiny blue fans in it

6 if you had a 670/680 or 7950/7970 and a SSD and bigger hd better mobo i rate it a 10 :)

What cooler should I buy to overclock my 2500k when I get the money?

What is the max you would go up to when you are saying mild overclocking?

the 212 evo should be just fine, and for the price of it and another fan you'd still be cheaper than the thermal take and have more than enough cooling for 4.0+ghz

So if I was planning on 4.5 would I be okay or no?

mostly only good until 4.2-4.4ghz then it gets toasty Going beyond that usually requires some voltage bumps.

If air cooling is so good why do people use water cooling?

one word, overkill.

anything worth doing well, is worth taking it way beyond what's necessary. The lower temps and higher overclocks are just a bonus. Water cooling is basically next step in cooling your components that will allow higher overclocks.
There is nothing like highly OC system that is silent ,it's a great hobby looks cool & very addicting :D

Large air coolers use lots of space and may not fit on some motherboard layouts, interfere with tall/finned DIMMs, can be too tall for some computer cases, may have other mechanical clearance problems, can give the case a cluttered look, etc.

So there are multiple reasons to go for liquid-cooling. In general though, for people who can fit a conventional HSF in their system and are not bothered by the cluttered looks of it, good air performs on par if not better than similarly priced liquid cooling.

+1 yeah closed loops don't preform any better than air if your talking about custom loops that's a whole different league and cost a lot of doe

OK, lets clear this up. A 212 Evo will almost definitely get you to 4.5 (with a good chance of going slightly beyond).

There are factors such as voltage needed, ambient temp, etc. to consider, but as you can see, I'm running at 4.5 on my 2500K with MY 212 Evo, and VERY easily, I might add. I CAN go higher, I just don't NEED to. Max Prime 95 temp is 64C on the warmest core, with the others at 58-62C. Yes, I'm running an extra fan for push/pull, but it really doesn't make THAT big of a difference.

A NH-D14 is awesome, no doubt, but there's NO WAY that you NEED one to get to 4.5 on a 2500K. If we were talking about a 3570K, then yes, but NOT a 2500K. A 212 Evo WILL be just fine.

Now, that case is only 7.48" wide, so ANY good air cooler will be a tight fit, but if the Newegg feedback is to be believed, a 212+/Evo will still fit.

Okay thanks for the info everybody and if any could post a good guide on how to overclock an i5-2500k to 4.5GHz since I've never done it before that would be great!

They're here in the Overclocking section, but I suppose I'll link them anyway.

I7 - 2600K / I5 - 2500K Overclocking Guide

Sandy Bridge K Series Overclocking All Cores Guide

You don't HAVE to do it exactly like either of those guides suggest (I certainly don't), but it should give you a good idea of what you're doing anyway.

OC'ing a 2500K (or any unlocked Sandy or Ivy Bridge CPU) is extremely easy, honestly. You really only have to worry about multipliers and voltage.

Okay then looks like I'll be going with the EVO. Thanks for all the help!
