Will Asus ENGTX 275 ( which has recommended of 550 W power supply ) run good on my comp with 600w power supply ? Edit: other specs : Got 2 Sata hard drives ( 500gb ) 4gb of ram GA-P31-DS3L motherboard , runnin' with Quad core 2.4ghz
At http://www.tigerdirect.com check out this 850-watt Modular X4 power supply: 135mm fan, 80-plus silver certification, and support for both SLI and Crossfire installations for only $199.99! You can’t beat that with a stick. So pick up this or any other of our wide selection of Ultra X4 Modular power supplies…you’re going to be glad you did!
Try this power calculator which is great for giving a guide as to what you'll be using wattage wise. It also allows you to factor in age, different hardware spec and peripherals.
I would recommend any of the Corsair PSU's! They are all rock solid and are officially supported by both ATI and nVidia.. That is if your looking to replace the PSU you currently have.. But as stated above, I can't see why you're 600W one wouldn't work..
Could you post the specs for you're PSU? Mainly the voltage on the +12v rail(s)..
