Intel i7 3770k and GTX 770 with 650w PSU?
Will I be able to run a GTX 770 and intel i7 3770k with a 650w PSU? Really hoping I don't need a PSU upgrading, because handling all the wires is a long tedious process.

A good quality 450W can handle your system. What is your PSU brand and model?

Going off the sticker on my Psu, I have a LSP Ultra 650w ATX Power Supply.


Ultra is a cheap low quality brand that offers sub par performance, but is it should be ok.


this powersupply will not run!!
you seriously have no idea what you're talking about do you?

here is a link that shows that your PSU only has 38 amps on the 12volt rail:
http://www.tigerdirect.com/applications/SearchTools/ite...

for the GTX 770, you need at least 42 amps on the 12volt rail, but preferably 48 or 52.

again, i'd recommend this one:
http://www.amazon.com/XFX-Edition-Modular-Certified-P16...

its semi modular, and great bang for the buck, if you want a cheaper one, get this:
http://www.amazon.com/XFX-PRO650W-Bronze-Energy-Certifi...

both of those PSU's can run what you want.

Strange, the sticker on my psu says that it has 64a on the +12v rail, Spooky shenanigans.


if it says 64a on the 12 volt rail you will definitely be able to run this setup.

hope that answers your question, if it did, make sure you close the thread

That's better language. :) 

And yes as I said before you will handle it fine just remember there is not enough headroom. ;)

First of all, the language is inappropriate in this forum.

Anyways, yes your PSU will handle the graphics card even when you overclock. However there will not be enough headroom.
