I have just done a full uppgrade of my old computer, i uppgraded everything accept the harddrives, dvd reader, chassi & my powersupply(500w)
this is my current confugiration:
Asus P6T Deluxe V2
I7 920
corsair ddr3 1600 MHz 2GB 3x
sapphire Radeon HD 4890
3 fans including the standard cpu fan, the other 2 is 120mm blue led
3 sata harddrives
+ 4 usb devieses
The problem:
before i bought the new parts i checked this configuration with http://extreme.outervision.com/PSUEngine
it showed 482w with 30% in Capacitor Aging,
so i figured my 500w would do but...
During installation i read the manual for my motherboard and it said i needed at least 600w otherwise my computer would become unstable.
in the manual there was also a link to asus own calculator
http://support.asus.com/PowerSupplyCalculator/PowerSupplyCalculator_right.aspx
which showed i needed 650w at least, which agrees quite well with the manuals recomendation.
Now my questions are:
How much power does my powersupply need to provide?
And why does asus & extreme calculate such a difference in watts?
