Hey guys! May I need some help? i used the Cooler Master Calculator to get the W. i know it's not accurate but i wanna hear from experienced users. If ever I want to upgrade my gtx 680 or SLI it, i would also buy a newer PSU. so the PSU in the new build will also be replaced sometime.

the current build:
recommended psu W: 296W

p4 3.0ghz prescott
intel-dg31pr
2 sticks dd2 kingston
1 ide 250GB seagate
asus 24x DVD-RW/DVD+RW Drive
Palit GT440
FSP HEXA 500W

-------------------------

the new build:
recommended psu W: 422W

i7-3770K
asrock extreme6
G.Skill RipjawsX DDR3 1600 8GB (4gbx2kit) CL9 Blue F3-12800CL9D-8GBXM
1TB WDC Caviar Black
asus 24x DVD-RW/DVD+RW Drive
Palit Geforce GTX 680 2048mb JETSTREAM Gddr5 256Bit
Seasonic X-660 660W 80Plus Gold Full Modular Power Supply

With my new build, is the PSU OK? Or should I decide to get on lower W like a 560W

Thanks in advance!

The new PSU is fine. It's probably good enough for SLIing if you decide to get another GTX 680.

For SLI GTX680's, I would personally want a 750w PSU just so I could have a little bit more headroom...

However, both of those PSU's will do fine.

I agree, you need a750w if you want future sli with 680.

I would just go with the a good 550w. When you want to upgrade your video card, just get a new faster single card, it'll use a lot less power than the card you have now.

When I would SLI another card or buy a new video card, I will also buy a new PSU. So the PSU stated above is somewhat like temporary. I want to know if the 560W is not sufficient. ^_^

Here is Guru3D's power supply recommendation:

GeForce GTX 680 - On your average system the card requires you to have a 550 Watt power supply unit.
GeForce GTX 680 SLI - On your average system the cards require you to have a 750 Watt power supply unit as minimum.

If you are going to overclock the GPU or processor, then we do recommend you purchase something with some more stamina. Source: http://www.guru3d.com/article/geforce-gtx-680-sli-revie... http://www.geforce.com/Active/en_US/en_US/pdf/PSU.pdf

If this is just a temporary PSU, then get a 550w. However, why don't you invest a bit more money now and just get a 750w PSU for the future? Or is the SLI not set-in-stone which is the reasoning for a lower wattage PSU?

It's because I wanted a fully modular PSU and a Platinum certification but in my current situation today, my budget is not gonna give me what I want. Thanks for your insight guys. Appreciate it. :)
