Whoever said that 700w is all you need is completely wrong, and they must have missed the SLI you listed in your specs. Obviously they have never actually built a system similar to what you've listed.

I tell you this because I am sitting next to 3 power supplies on the floor next to me, a 700w ToughPower, a Silverstone 1000w single-rail, and a 1200w CoolerMaster Silent Pro Gold. Only ONE of these power supplies work with two GPUs under rippin' shreddin' ass-tearin' load. I'll give you a guess which one it is. The 700w actually worked for 2x8800GTX, but times have changed. The Silverstone could not keep up with 2xGTX285, and failed outright with 2xGTX570. The CM is the glass slipper that fits.

Power supplies are rated like car audio amplifiers. The piece of junk that claims 120 watts per channel is only true at peak, but will RMS at 60. The top brand that claims the same output is actually RMS at 120 and peaks at 200. Both are sold as 120s... get what I'm saying?

Duty cycle is the key. The CoolerMaster is rated at 1200w at 100% duty cycle, and can actually peak around 1600w for brief periods. The Silverstone is rated at 1000w peak, but the real output is more like 700w at 24/7. And guess what, the CoolerMaster is $100USD cheaper than the Silverstone.

Bottom line is, buy more power supply than you think you'll need. Who knows, you may want to add more stuff eventually. A good PS will last a few builds, and I don't forsee the specification or connections changing any time soon, so spend a little extra in that department.

Also, how much does a Sandybridge set up cost? Because here in the UK it would be cheaper to go sandybridge and you get better performance, don't see why you would go with a 950...?

@
Zeusboltthrower thanks for the reply man.. What psi do you think will go good with my build cause when I check my wattage in antic psi calc I get 900w minimum so I thought 1000w should do fine...
If not what do u think is good enough?

560s use much less power than 570s.

1000 is way more than dual 560s need.

I would have said get a 2500 or 2600 if your not overclocking. But you can't buy motherboards for another few weeks, so i guess your stuck with a 950 if you want to buy now.

Nothing wrong with a 950, but if you're not going to overclock a 2600 would have been a great buy.

I haven't bought anything yet.. So yeah... Anyways what is the price of the 2600k in Australia?

I chose 950 as it fulfills my needs
post #40 of 51
12GB ram - are you doing photo editing or video editing or something else that needs 12GB?
Just wondering, because 6 is enough for most purposes, but if u need it, you need it.

Also I've noticed that the 960 price has dropped considerably. Not saying you need it or anything, but just in case ppls hadn't noticed there's a price drop.

You wont have any CPU bottleneck with a 950, and two 560s should do very well.

HX850W does my two 460s quite well.

* A second card requires you to add another ~175 Watts. You need a 700+ Watt power supply unit if you use it in a high-end system (800+ to a KiloWatt is recommended if you plan on any overclocking).
