Hi, I am getting a new PC soon, and was wondering if I should get a 450w Quiet 80 Plus Dual Rail PSU or a 650w Corsair Enthusiast Series.
8GB RAM (2x4GB)
120GB Intel 520 Series SSD
PCSpecialist.com has told me ''We have calculated your specification to require around 416W of power including a 20% allowance.''
So should I go with the 450w or the 650w because as far as I know that the Corsair will last me longer.
power supply calculations always over compensate for everything. you'd be probably be using 250-350W at the most. on the contrary though because it is a dual rail design (I've looked on PCspecialist and they don't give any further info on the PSU) it won't be able to feed all of its power to the graphics card and CPU, which are the power hoggers in a PC. without any details we can't say how much you'd load the PSU, so for £40 extra I'd say go for the corsair and piece of mind, the power supply is one thing you shouldn't skimp on.
