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. xaira August 4, 2009 10:12:30 PM for real 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. This is the best buy atm from Corsair: http://www.newegg.com/Product/Product.aspx?Item=N82E168... Can't find your answer ? Ask !
