I'm doing a mini ITX build and have the following components:


i5-4670K
GTX 680 FTW 4GB
2 Vertex 4 SSDs
bunch of water cooling stuff.

The specs for the 680 say it needs a minimum of 550 watt PSU. I have a Corsair HX850, but it is too long and sticks out the back of the case, which I just cannot stand. I was hoping that the CX600 would be enough power for this build. Or would the CX750 really make the difference?

I do plan to overclock considerably (4.8Ghz or so)

The 600 is on sale for 54 dollars at microcenter, hence my dilemma. The CX750 is still 89 bucks.


Thanks.

GeForce GTX 680 - 38A on the 12V minimum, found in a 550W PSU usually.

Just make sure any PSU on this list meets that requirement: https://www.overclock.net/t/183810/faq-recommended-power-supplies

Also, that HX850 is 180mm long. Find the suitable length PSU as required by the case's manufacturer.

What case are we talkin' about?

My brother ran into a similar issue with his Bitfenix prodigy build. A psu sticking out the back of the case can be unsightly. Which case do you have? I'm guessing it fit standard size 160mm psu if you can get the HX850 in there at all. You don't need a 750w for your system and I'd suggest getting something better than the CX series. Buying at microcenter you are at the mercy of their prices and selection which is almost always leaves quite a bit to be desired. You'd honestly be better of buying a 550w rosewill capstone or xfx core series off newegg than getting anything microcenter sells in that price range.

Sorry, completely forgot to add what frickin case it is...

It is a bitfenix prodigy so the sticking out PSU is just gross to me.

I really want to get myself something along the lines of 650 watts for some headroom, and don't need ot buy it from Microcenter. It was just the closest store, but I can order online as well.

So I'll stay away from the CX series. I have one in my server at home, but it doesn't do anything but sit there, so it's never really taxed.

You still dont need 650 watts even if you want headroom

http://www.newegg.com/Product/Product.aspx?Item=N82E16817182261 450 capstone will be more than enough.

If you want to jump up to 550 for the hell of it then get this one

500W has all the headroom you will ever need.

My system, which is more power hungry than yours to start with, overclocked to 3770k 4.6Ghz 1.3V and 7950 1150Mhz/1400Mhz 1.25V, managed to hit a peak power draw of only 374W (assuming .9 platinum efficiency) during AIDA64 system stability test. Skyrim gameplay power draw hovered around 225W, and 3DMark11 peaked briefly at 288W.

My point being, even a 450W will be enough and leaves you with ample overclocking headroom.

I can second this.

Most people think their hardware use far more power then it really does

And newer hardware use less and less power for each generation

well then I would go with the capstone 550M. if you wanna save a few bucks go for either the xfx core 550w or S12 520w, neither as good as the capstone 550, but both fine as well. you can't do SLI and even with a gtx780 or titan you'd not need more than a 500w with a single gpu.
