Power supply GTX 560

With the parts listed it could likely handle it. But safely (me being a paranoid batard) I would upgrade to a 650 or 700. The one problem is the Cpu, it may not be able to use the gtx 560 to its full ability, i'm not very knowledgable on this particular model of processor, but you may want to do research into whether the gpu will be bottlenecked by the cpu. The positive is these are older parts, so generally require less wattage. The 560 uses a max of 130watts while your cpu uses 95watts. Sice those are the most power demanding parts. That leaves a good margin for the rest of your machine. To conclude, if what I am reading is correct (3 hdds?) the 600w will handle it, though if you are willing to spend about 50$ get a 650w. (im running a gaming computer with a 2500k and crossfired 6850s and im using a 750)

The GeForce GTS 250 and GeForce GTX 560 are both 150 Watt graphics cards. NVIDIA's power supply requirements for both cards is exactly the same (i.e. Minimum of a 450 Watt or greater power supply with a combined +12 Volt continuous current rating of 24 Amps or greater and with at least one 6-pin PCI Express supplementary power connectors.)

If your Cooler Master eXtreme Power 600W power supply is currently working with your GeForce GTS 250 it should also work with the GeForce GTX 560.

Its a power supply that can't be trusted though, since it can't even deliver its labelled power.

I am considering buying a Radeon HD6850 o HD6870, but I need to know about the power supply.

already has the connectors 6 pin X 2 PCIe

For a system using a single Radeon HD 6850 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 27 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

For a system using a single Radeon HD 6870 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 30 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.

The Cooler Master eXtreme Power Duo 600W (RP-600-PCAR), with its maximum combined +12 Volt continuous current rating of 35 Amps and with two 6-pin PCI Express supplementary power connectors, is theoretically sufficient to power your system configuration with a single Radeon HD 6850 or a single Radeon HD 6870.

The RP-600-PCAR is actually manufactured (i.e. OEM) by Seventeam. That power supply cannot even deliver the power specified on its label. The switching transistors have a high probability of burning out if you were to attempt to draw 600 Watts from it. Use it at your own risk.
