What PSU should I use in this build?

[davk]

Hello everyone,

I really don't know what power supply I should choose as the title already said..

Here my parts list: http://pcpartpicker.com/p/16Wel

They say it will only use 441W, so is a 500W psu enough?

Thanks in advance!

I Would go with a 600w or a 750w if you plan to upgrade later

Those watt calculators are only estimates, so if you overclock your stuff, you'll need at least 600W PSU to be on the safe side.

What I do is round up to the nearest 50, and add 100W just to be safe. So for your build, I'd say at least 550W.

I would go for something like a 650 or 700 watt but make sure you buy from someone like seasonic or corsair and make sure its at least an 80 plus bronze rating

IF interested, drop the 3770k for a 3570k if a gaming build
get a 680 for the extra cost

And bump up to an 600W would be my recommendation for overclocking overhead.
I got a weakness for the SilverStone Striders

500W would be enough for this system but if you plan on upgrading later without replacing your PSU I recommend you getting a 600W-700W PSU.

Get a cx600 or 600w bronze for overclock headroom . In all reality a 550w would be fine as well.

500w is cutting it close depending on the reliability of the psu. Headroom is good for the psu.

a quality 550 watt unit would handle it easily,but generally for 'future-proof purposes it's generally recommended to go with a 650 watt,especially now that 650 watts can handle upgrading to sli/crossfire configurations in most scenarios

I'd pin the power consumption at a guess at sub 350 watts under load @ stock settings.

and now to check my guess-timation

 

3770K - 77 watts

gtx 770 - 180 watts

HDD - 10 watts

SSD - 3 watts

sp120*3 - 7 watts

c70 case fans - 11 or less watts (idk actual current the fans run at,picked .3A as it's typically at or below that)

wifi card - 10 watts max (low profile pcie standard)

dvd drive - 10 watts

pump - 1 watt (doubt it uses more than the h100 pump,which uses 1.2 watts)

h100 fans - 8 watts assuming you use stock fans

~317 watts max power consumption
