I think it would be close. A 570 needs about 16 amps, peaking to 22 amps under heavy load. Figure another 10 amps for the CPU and that is close to 400 watts not counting the rest of the system.

A 650 watt PSU would be better.

For a system using a single GeForce GTX 570 graphics card NVIDIA specifies a minimum of a 550 Watt or greater power supply that has a combined +12 Volt continuous current rating of 38 Amps or greater and that has 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.

Overclocking of the CPU and/or GPU(s) will require an additional increase to the combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclocks you are trying to achieve.

The HEC WinPower 550W, with its combined +12 Volt continuous current rating of 33 Amps and with ???? 6-pin and ???? (6+2)-pin PCI Express supplementary power connectors, is insufficient to power your system configuration with a single GeForce GTX 570.

The OCZ ModXStream Pro Series 500W (OCZ500MXSP), with its combined +12 Volt continuous current rating of 36 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is insufficient to power your system configuration with a single GeForce GTX 570.

The OCZ ZS Series 650W (OCZ-ZS650W), with its combined +12 Volt continuous current rating of 46 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is sufficient to power your system configuration with a single GeForce GTX 570.
