In Thermaltake website (http://www.thermaltake.outervision.com/), using power supply calculator Thermaltake suggest that TR2-420W power supply is enough for the following configuration PC.
System Type: Single Socket
Motherboard: High end Desktop
CPU: Intel Core 2 Quad Q9650 3000 MHz (CPU Utilization: 100% TDP)
RAM: 4 Sticks DDR2 SD RAM (4GB)
Video Card: ATI Radeon HD 4850 (Video Type: Single Card)
Hard Drives: SATA 1HDD
DVD-RW/DVD+RW Drive: 1 Drive
System Load : 100% (peak load)
After Calculation The recommended PSU Wattage is 306W. And the pop up comes along with the calculation page suggesting TR2-420 W Power supply.
But according to ATI Radeon the HD 4850 card requires minimum 450W PSU.
Now I want to know whether 420W PSU is enough for the card or not.
