620w 80plus gold enough?

[Angelus2141]

So ive used the calculator but honestly I prefer asking you guys anyways.

 

Ill be running 

 

I5-3570k

asus gtx 560 ti (possibly upgrading to a 650 later)

Z77A MSI GD65 Gaming motherboard

Kingston Hyperx 120gb SSD

1 TB Seagate Barracuda

1 DVD RW (possibly getting bluray later)

Corsair H100 (not the i version)

 

in a corsair 650D. Im currently looking a HX 620w. from what ive read all HX are 80plus gold. The calculator said I need 515w. The 620w would give me 545w at 80 plus gold i believe. I couldnt understand on the calculator if it was 515w at full load or what.

 

So should I get the 620w or look for a 650w or maybe even the 750w

 

Many Thanks

you are good with every choice you got there and you will still have pretty much headroom for overclocking

Around 600 is perfectly fine, you can even get away with 550w.

You're counting it wrong, efficiency of a power supply is counted so that a 620W power supply draws more than that from the wall to give 620W to your components.

easely, i got an i5-4670 and a HD7950 overclocked and i get a max power consuption of around 350 watts

Yes, 620W will be more than enough to even run a second graphics card.
