Is corsair 650w psu enough for gtx560ti sli cards

That's 500 watts already on the SLI... I Recommend getting the Corsair Tx750 v2 or Corsair Tx850 v2...

They recommend at least a 700W PSU and if you are gonna overclock it a 800W PSU

That would be enough. a GTX 560ti usually uses no more than 160-180w on full load while the cpu should be around 95w under full load or more. Even when under full load on stress programs, you would probably be around 400watt's on the 12v rails. More than enough for a quality psu from a reputable company such as corsair.

Only time where you'll even see them running at these power levels are when you're running a stress testing program. Most of the time, it will not get that high. A corsair tx650 is more than enough to power two gtx 560ti's. =]

The 650 watt PSU will run your system, but I estimate that your PSU will be running at around 85% of capacity at full system load.

I would put in a good 750 watt PSU.

The way I understand PSU's that would have the unit at maximum efficiency or very close to it.

Just get a Corsair Tx750 V2 on it and your good... Overclocking the Video Card dont use a lot(Around 10 watts or so) until you start overvolt it(Getting higher clock)...

Overvolting any of the Fermi cards could well end in tears and a pair of OC'd 560Ti's and an OC'd 2600k can be run by a five year old 620HX PSU.

He's running 560Ti in SLI not in single card... 560Ti SLI requires more power or twice the power of a single 560Ti so i wouldn't compare it an single OC 560Ti+OC 2600k... Also Overvolting dont usually lead to tears(depends how much you OV it) but sometimes leads to winner

So why would a single card need such a large PSU?

IDK, people cant really estimate how much power they need, they just needa get a 700Watts on a 1grand build or at least i seen on nearly every 1grand build...

Like I said earlier, that rig could be run by a five year old 620w PSU and I know that for a fact.

my psu is corsair 700w ..in future i will sli my card ..my mobo is p67a-gd55

Depends on what cpu that you have, if your overclocking, and what other components are.

Here is Guru3D's power supply recommendation:

GeForce GTX 560 Ti
On your average system the card requires you to have a 500 Watt power supply unit.

GeForce GTX 560 Ti in 2-way SLI
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).

Seems to be a common question.

Something like a Corsair TX650 would work , but you would have little in reserve.

I'd use something like a TX750V2.

By the way, if you are going to overclock only the CPU, that will not add more than about 25 watts to the load on the PSU with any modern Intel CPU.

Have you ever stress test your computer to maximum/near max? There's a peek were your computer will shutdown due to overwattage... LMSAO...
