Nvidia 780ti + PSU upgrade

[Rosstafa]

Hello, this is my first post here so I apologise if this is in the wrong section or something.

I have had my PC that I bought from Vibox for a couple of years now, and I am now looking at upgrading my graphics card and power supply. I'm not too tech savvy when it comes to what parts are compatible etc, so I was wondering if anyone would be able to give me advice as to whether these parts are appropriate upgrades e.g. they'll be compatible with one another.

Current PC specs:
Motherboard - Intel Core i7-3770K
Graphics card - Nvidia Geforce GTX 560ti
PSU - PowerCool PC-550AUBA-M (550W)

Upgrades:
PSU: Corsair CP-9020056-UK RM Series RM850 80 Plus Gold 850W ATX/EPS Fully Modular Power Supply Unit

Graphics card: Asus Nvidia GeForce GTX 780 Ti

Will both of these parts be good upgrades and fit easily into my current PC? From my research, all I can find is that the graphics card requires at least 650W or so power, and a PCI Express 3.0 slot which my motherboard seems to have. Not sure what else I need to know in order to know whether this parts can easily fit into my PC, so if this looks fine and I should pull the trigger, I would like to know. Don't want to buy it and find I've missed something and the graphics card won't work with my motherboard, or my PSU doesn't connect to my motherboard/graphics card etc. Also, if there are other suggestions for alternative parts of similar price/power but better quality, I am open to suggestions.

Thanks, sorry for the essay!

The 750 and 850w versions of the RM use cheap caps, here's a better PSU option

Get a GTX 980 it is faster than the 780Ti and around the same price.
That 850w PSU is enough to run 2 gtx 980s.

not going to lie you could probably get away without upgrading your PSU. I have msi X99s SLI PLUS motherboard, i7 5820k 780ti's in sli with 2 ssds 1 hdd, full custom water loop with 2 big rads 18 fans nzxt hue and fan controller and on a 700W PSU.

First off why GTX780TI When you can get the GTX 980 that performs better uses less power and cheaper in most countries and have 1 more GB of VRAM
As for the PSU I recommend that you go with Thermaltake as they give Longer warranty and that's very important when it comes to PSUs not to mention in most cases no one had problems with them while using them while corsairs users had some troubles with them and yeah 850W is more than enough

+1; the Corsair RM series definitely uses poor capacitors which is a risk to your components.

The 980 seems like the best option then, along with this power supply?:

Assuming they're all compatible then? I have little knowledge of this sort of thing, so I'm not sure whether it's just plug in and go or what.

This PSU is good and you should go ahead with your purchase if you like
