which power supply for my build?

post #1 of 43
Thread Starter 
Just want to hear some opinions and reasons. here is my build
NZXT Switch 810
I5 3570k
MSI Mpower
MSI GTX 680 lightning
Swiftech H220 cooler
Corsair vengeance 8GB
6X 3.5" Hard Drives
Lg Bluray drive
10X 140 mm case fans
and maybe some case lighting.

I had chosen the Corsair AX750 and I was wondering How the NZXT 750 holds up to it?

will 750 be enough considering i may expand to sli?

For this build because there's only one GTX 680, all that you need is a 400-450W power supply.  This is not the absolute minimum, it's the sweet spot.

 

For two GTX 680s, a 550W PSU would be enough.  Of course, a 650W PSU would make it easier to have 4 x 6+2-pin PCI-E cables without breaking the bank.  For example:

 

650W Rosewill CAPSTONE Modular Cable Version Series for $104.99 shipped

 

This is a high-end modular PSU.

mm yeah but its not full modular and the sleeve job looks terrible.... and does a higher wattage psu then needed lead to more stable overclocks?

The quality of the PSU is far more important than higher wattage.
As stated above, your setup will no where near reach the limits of the Capstone650 even after adding a 2nd 680, oc'ing both of them & the CPU.

the cables on the NZXT that are not modular your going too use anyway, all the other cables are modular.

I would choose 1 of these 2 depending if you bought the 810 black or white.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817116011

and just because you dont need all that power is no reason not too buy it.
I have more power supply then I use but it makes me sleep better at night.

No, only the quality of the PSU's internal parts (e.g. the capacitors).

The Rosewill CAPSTONE Series are enthusiast-class.  As I said, they are high-end.

 

Are you really going to spend more just to get something that's fully modular with better-looking sleeving?  I mean, that just seems silly to me.  I'm sorry for my blunt honesty.

 

You do not need anything 'bigger' than a 550W power supply, but again a 650W PSU makes it easier to find a good PSU that has 4 x 6+2-pin PCI-E cables without breaking the bank.

 

If you absolutely, positively must have a fully modular PSU, then try this:

 

650W SeaSonic X-Series for $119.99 + $4.99 shipping

 

Edit:  I just noticed that Newegg does not have any fully modular 550W PSUs that have 4 x 6+2-pin PCI-E cables.  So the 650W X-Series is the best you can get without spending a fortune.  Although for me, $124.98 shipped is a fortune.

 

Anyway, you do not need anything bigger than a 550W PSU for two 680s in SLI.  A quality-made 550W PSU would be the sweet spot, and a 750W unit would be a complete waste of money.
