Hi! I'm fairly new to the computer building scene and need help picking the correct power supply for my build as it gets VERY confusing for me. If you could tell me the appropriate wattage my build will use that would be great but linking me / telling me what power supply I should get is fine also. And I should also note that I picked out a power supply but not to sure if it'll work but here is the one that I picked (Seasonic SS-560KM Active PFC F3 - Its a 560W 80 plus GOLD modular psu).

UPDATE!!! - I have picked out a power supply that I'm pretty sure I will get and thats the [SeaSonic X Series X650 Gold ((SS-650KM Active PFC F3)) 650W ATX12V V2.3/EPS 12V V2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply] Its from seasonic which I heard great reviews from and its a 650W 80 plus GOLD modular psu! Its $130 compared to the 560W one thats $125 and its 28% off at the moment! Amazing deal from what I can see so I'm most definitely going to go with this power supply. Let me know if THIS power supply will be good enough / is decent but I'm pretty sure it will be. :bounce:

And will my PSU still be suitable if I were to make upgrades to my build like adding an ssd card or upgrading my video card etc? Basically I'm asking if I will have a reasonable amount of watts left to use if I were to upgrade my build.

It should be enough if you added an ssd or other part but a video card idk elsewhere on the forum it says it takes a max of 240 watts and yous cpu takes 77w so yeah its plenty for this build but if you wanted to SLI in the future go for something in the 700-800 to be safe. Be sure not to skimp though because sometimes high wattage psus can blow your motherboard!

The latest cards have low power consumption, the days of the 5XX series and their Power consumption is over, you will need right around 650-700w, in order for you to add another card later.

I think I've found the right PSU now (I've posted the new one above). Let me know if you guys think it'll be compatible with my build and what your opinions on the PSU I picked.

that 650 X series will handle anything but a 7970 Xfire configuration (that would need ~750)

besides the more budget minded XFXs, those are my favorite PSUs . . .

Another good choice in PSU. Will run your rig with 2 x 660Ti in SLI or a more powerful single card.
