Is 620W enough for this build?

hello =)
First of all, im new here, i was told by a friend that if i have a question, this is the best place to ask, so ill give it a go =)

this is the rig im getting:
i5-2500 Processor 3.3GHz 6MB
Gigabyte‎ ‏Z68A-D3-B3
G.Skill DDR3 8GB sniper 1333MHz
Samsung Spinpoint F3 HD103SJ‎
Intel 120GB SSD X25-M Sata II 2.5'' SSDSA2MH120G2K5
Asus GeForce GTX 580 1536MB
Seasonic M12II-620 (Modular)
Samsung DVD±RWx22 ‎SH-S223
CoolerMaster HAF-922 +1 side 200mm intake

When i ordered this today, the seller guy said he is a-bit worrid im getting a 620w PSU, for the GTX580GPU, and thinks that it is a GPU that needs at leas600W. ive checked here:
http://www.overclock.net/power-supplies/1045231-phaedrus-quickndirty-psu-calculator.html
and it "class B" takes 200-275W, and needs the PSU to be 500W.

I just need to know, concidering I'm not going to SLI,Crossfire or OC, can i be 100% calm that this PSU is mor ethen enough?

Ty!

  1. Enough for default , you will be fine. Power consumption gtx 580 fulload 350w

  2. "By default" meaning if i don't SLI/OC/whatnot?

    and if it can reach a maximum of 360, that means i need to hope the rest of the rig doesn't take up more than 260W? right? i actually need it to be Alot less than 260W? or am i getting this all wrong?
  3. yes it is fine, my setup is almost the same as your and I have 2 6950 is xfire on a coolermaster 750w and i oc the cpu to 4.6. Its good to go
  4. that sounds like i haev a good enough ball room... even if i would want to OC the GPU and CPU later (much later) on...

    ty guys.
  5. No prob, happy gaming
