Hello everyone.As soon as the winter comes or maybe earlier i will build a new pc.My question is how powerful should the psu be in order to carry a gtx 770 or 780,an z87 motherboard and a haswell also 2 hard drives and an ssd.

 

Beware of him that is slow to anger; for when it is long coming, it is the stronger when it comes, and the longer kept. Abused patience turns to fury.

Do you plan on future upgrades? Like maybe SLI?

No.One card only.

550w, 500w, that is with headroom for  possible future upgrades. 

You can use the Newegg PSU calculator

This is a extremely useful tool, and this calculator says you will be pulling around 440 watts.

Your pump is probably going to pull 24 watts max... Dont go with a PSU that is like 1200W when you only need to use 500W... Go with an 860W for the extra headroom if you want to overclock or go SLI.

I like the color scheme of Noctua fans. Deal with it. Forget about the bad memories of the past.

Forget about the bad memories of the past, take the good ones along with you through the present, and look forwards to the good things that will come in the future.

I would go with a 650W psu like a TX650 or a XFX Core 650W if you are on a budget. If you are not, go with a Seasonic X 650 or HX650 Gold.

A decent 600w is plenty.
