New build - PSU help?

[chizom]

Hi everyone! (my first post here

 

I got a

> i5-3570k with a ASRock Z77 mobo.

> 16 GB of G.Skill sniper 1866

> a SSD and HDD 

> MSI GTX 770 2gb oc

and i did order this http://pcpartpicker.com/part/xfx-power-supply-p1550sxxb9 (XFX 550w 80+ bronze) for my PSU but i'm wondering if thats going to be enough wattage too power the rig safely.

 

I've seen on other forums some say its fine and others say its risky but depending on the psu because the GTX 770 says minimum of 600w.

 

Thanks for any help

I would have went with a 650W. Peak efficiency is around 50% on a power supply.

 

Honestly, you should have asked first before you bought one.

That is going to be enough

gtx 770 uses 180W at peak in games. you are more than fine with all the OC you can do.your rig will use under 300W while gaming

Thanks for the responses, ya i should have asked first i know.

 

I got the psu first then jumped on the msi gtx 770 during the black friday deals so i wasn't planning to go for that.
