I'm soon upgrading my pc from gt 330 to 6970. my question is about power supply I'm certain that mines isnt powerful enough but I would like some help explaining the PSU itself my current one is.
AC [ 100-127/220-240w, 10/5A, 50/60hz ]
DC [3.3v| 5v |12v1|12v2|5vsb|-12v]
DC [16A |20A| 18A | 18A|2.5A|0.5A]
MAX [ 450W ]
Peak[ 500W ]
Can anyone explain this information so in future I can easily read what I need from a power supply as I know that W's isnt everything, it's also got something to do with 12v rails and Amps
For your first step in sizing the PSU, I would use a PSU calculator like this one: http://www.thermaltake.outervision.com/
Just enter the values as they pertain to your build. There's a spot there for you to enter the graphics card you want to use, among other variables...
Seasonic X series, Antec SG, HCO, HCG series are also great choices......
is there any recommended brands of PSU's like corsair maybe? as I do not know my PSU make and would like to get a more trusted brand of psu
Brand names really can't be used as a measure of quality ...... even within the manufacturer's product lines there can be significant variances.......most of Corsair's HX series get 10.0 ratings for example but the 1000 / 1050 fair rather poorly in comparison for example with their siblings.
