Power supply requirement:Thermaltake vs ATI Radeon Tags: Power Supplies Thermaltake Components Product Last response: August 5, 2009 3:36 AM in Components Share Laurel August 4, 2009 9:32:35 PM 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.

You want some headroom between your estimated usage and PSU rating. m 0 l xaira August 4, 2009 10:12:30 PM for real m 0 l Can't find your answer ? Ask !

If you want more headroom for a more powerful video card later down the road then spend the extra few bucks now and avoid having to replace the psu along with the new card.
