I know their are MANY power calculators out their but !'m getting conflicting results.
First My PC Specs:


  • ■ AMD FX 8150 OC to 4.2Ghz (upgrading)
    ■ Gygabyte GA-990FXA-UD5 (upgrading)
    ■ Kingston 4gb DDR3 X 4 16gb total (upgrading)
    ■ EVGA FTW Nvidia GTX 970 (1 6pin +1 8pin connection, Keeping)
    ■ 2 TB WD Black HDD (Keeping)
    ■ 128GB OCZ Agility3 (sata, Will upgrade, or change to PCIE or M.2 or Raid)
    ■ LG BluRay Reader/CDRW combo Drive (Sata)
    ■ Multimedia Card Reader (keeping)
    ■ Corsair H80 (I forget but the single fan radiator, Upgrading/Replacing)
    ■ 120 mm case fan X4 (= or - depending on case)

So thats all the stuff internally connected. This system used to be a Dual hd 7770 crossfire setup and 800 w PSU (it still works but the fan is dieing and the noise is unbearable so rather than replacing the fan and the PSU being 3 years old at this point (80+ bronze) I feel its time for an upgrade.

Also I am going to be upgrading my Motherboard, CPU, Memory, SSD and Case soon ( as i said going on almost 4 years for me its time for that)

So I am pretty sure this time around I'm going to go with an Intel Chip set and corresponding Motherboard and not planning on buying another PSU. So Currently I am At the Assumption that I Should be fine with a 750w PSU?

So with all that (probably extra information) will a 750W Suffice for my needs and for future proofing? (i was considering just replacing the fan but IDK if i want to mess with those capacitors)

If you made it this far THANKS and If you would like to put in an opinion on what CPU i should get as an upgrade AMD to Intel isn't as straight forward as just getting the next best chip from the same manufacture as my system is changing from the red to the green team.

THANK you in advance i always get knowledgeable and informative answers from this site and i appreciate it.
 
Solution
For the parts above all you need is a good 550w unit. This would power the specs just fine, but not leave much room for future upgrades:

Power Supply: XFX 550W 80+ Bronze Certified ATX Power Supply ($55.99 @ SuperBiiz)
Total: $55.99
Prices include shipping, taxes, and discounts when available

If you wanted some padding for future upgrades around a new PSU, this would be a fantastic choice:

Power Supply: EVGA 750W 80+ Gold Certified Fully-Modular ATX Power Supply ($89.99 @ Amazon)
Total: $89.99
Prices include shipping, taxes, and discounts when available

WOW thanks for such a quick answer I think Im going to shoot for a 700w modular and that should be fine. I don't prefer to use sli rather than getting a better single card so I think you say i am almost double what i need now ill be fine with a 700. I'm not sure but i think that will be fine for some padding for the future. As I will not be buying an Intel 8 core For my needs I think quad core Intel CPU's use much less power than AMD chips esp the 8 core chips. SO thanks for your help and your quick help at that!!!
