So according to the following website:
http://www.fsp-group.com/english/1 [...] &proid=541 my power supply says the following:
Model Number: FSP450-60EP
Form factor: ATX12V & EPS12V
Wattage: 450
Rating: Bronze
So I've asked a couple of questions and some say its 500w and others say its 360w.
I got this answer from a previous question I asked:
"Concentrate on the wattage coming from the 12V rail as that's what your motherboard really uses to convert it to lower voltages:
http://www.playtool.com/pages/psur [...] rails.html Therefore, I would consider your sample PSU to be rated at 360W."
nVidia specifies that maximum power draw for the GTX 560 is 150W. FSP is a quality OEM PSU mfr and your specific PSU is bronze certified. With 36A over two rails, your PSU is sufficient.
What CPU is being used and is it being overclocked?
The GeForce GTX 560 will typically draw a maximum of 13.6 Amps from the +12V rails during gaming.
If you were to run Furmark or OCCT GPU stress testing the current draw from the +12V rails will increase to 17.7 Amps. That's almost at the 18 Amp limit specified on the power supply's label. That could trip the over-current protection circuit depending on how the PCIe connectors are wired to +12V rails of that power supply. Just don't run Furmark or OCCT GPU stress testing.
