What PSU

Hi everyone!


I'm palling to make a new PC, but I'm not sure, what kind of PSU would fit.

Here is my build:


INTEL Core i7-3770K 3.50GHz 1155 BOX (oc'd to 4,5 or so)
ASUS P8Z77-V
GIGABYTE GTX690 4GB 512bit DDR5
OCZ SSD SATA3 Vertex 4 256GB
WD 2000GB Caviar Black 7200rpm 64MB SATA3 WD2002FAEX
NOCTUA NH-D14 or CORSAIR Hydro Series H100i
ASUS DRW-24B5ST Black BULK


They suggested me a "Seasonic S12 620W".
Is this good/enough? (I'm not a PSU expert :/)


Thanks! :)

More about what
  1. There is no PSU wattage requirement info for the ASUS P8Z77-V board on the ASUS website. Loads of specs and features but nothing about what PSU is required.
    A Google search didn't bring up that information either, so all I know is you need an ATX-type PSU, but I guess you already knew that.

    A 620-watt PSU should be okay since that board is known to consume less power than most, but that's only a guess.
  2. the "suggested" PSU is a very good one and plenty of power for your set up
  3. You guys sure?

    he has got a 690 after all.. Nvidia say minimum 650W but since it's close to 650 and a good make you should be ok. since the card maximum power consumption is 300W i doubt the rest will take 300W.

    Yeah, it'll be OK realhardtech suggests 620w (min 46a on the +12v), M12 has 48a on the +12v
    and they are thorough n accurate on these recommendations.
    So, that Seasonic should be fine even with liquid cooling.

    Wouldn't hurt if he went a little higher (n got 50+a on the +12v)
