I am using a thermaltake 500W toughpower for the identical setup (with small changes) and it is working without a problem at all, very solid.

I also have numerous (large) fans and lighting in my case, as well as a few HDD's.

so what your saying is i should get the thermaltake for powering my msi gtx 560 ti OC and the 125w phenom ii x4 955be and 4G ddr3 ram and 500G hard disk and dvd driver and couple fans and mouse and keyboard ?

 

[itzdanielp]

I would suggest going a bit larger than 500, maybe 580 or 600.

 

[hameem 1]

why ?

 

[itzdanielp]

If you use a PSU calculator like the one linked above me your system will draw about 520 Watts. You always want a little headroom, or else your PSU will not run efficiently, and will not last as long.

I checked my PSU again, and I have a 580, not a 500.

i used the thermaltake calculator and it shows that i only need a 380w PSU .. ?
PSU calculators are not ture !! i am asking real people if thermaltake tr-500w will power gx 560ti system with phenom ii x4 955 125w

The PSU calculators recommend the wattage for the power supply, they don't give an estimate for what the system actually uses.

Out of the power supplies listed in the OP I would get the Silverstone Strider Essential 500W as it is going to be reasonably high quality (which I would have to be convinced is true of the TT) and it has the two PCIe connectors that are required (which the OCZ doesn't have).

For a system running a single GeForce GTX 560 Ti the minimum system power supply requirement is one with a minimum +12 Volt continuous current rating of 30 Amps or greater.

This minimum system power requirement is based on a PC configured with an Intel Core i7-960 3.2GHz processor (Max TDP: 130 W).

What's your point?

During that review they used an OCZ GameXstream 700W (OCZ700GXS) to power their test system. OCZ specifies a maximum combined +12 Volt current rating of 56.6 Amps for that power supply unit.

look at the total system power consumption of the gtx 560 ti
