What PSU for my rig?

Relativity new to PC building. I want to use the CORSAIR RM Series. Don't own a voltage checker so here are the specs.  

8350 @ 4.34

212 Evo Cooler ~~~(Might get upgraded to a closed loop)

Sabertooth 990 R2

8GB (2 x 4GB) 1866 @ 1.5V ~~~(Will be upgraded)~~~ 16GB (2 x 8GB) 1600 @ 1.5

HyperX SSD (120GB)

7200RPM HDD (2 x 1 TB) 

GTX 770 

I can get both the 550 and 650 for the same price. 

id say 650. i gave u some extra head room so you could do a 550 but i would really advise against it.

As long as it is 80+ bronze certified or better ... either will work.

there's not a need to get a 650W...

a 500W will do fine and have plenty of space

Linus was only pulling a little over 500W from the wall using a much higher configuration than yourself

  • 3960x
  • Quadro 4000
  • GTX780

That being said you may even get away with a 450W PSU but i would not push it because components will age over time and you may or may not upgrade your system.

Getting a quality 500W will be your best solution however if you plan on getting, say a second gpu to SLI you could want to gett a better PSU right now, if that's the case a 650 or 700W will be adequate.

Ideally ... you want to be at 80% usage of available capacity. 

550W is basicly more then enough for most single gpu setups.

But if you can get a 550 and 650 for the same price, then grab the 650, thats no brainer offcourse!

Of course! Would you say a 650 is enough for the setup above, but instead of a 770 a 780 Ti? Plus a few case fans and a blu-ray drive? My gut feeling is yes but again I don't have that much experience. Thanks.

650W is way enough realy for every single gpu setup. even 550W will be enough. But again for the same price grab the 650W. 780Ti or R9-290 (x) you will all be fine with 550 / 650W.

above 750W is only in question if you talk about dual gpu setups.

Thanks for your help & time. I went with the Corsair RM Series 650W. It was more than I wanted to spend but I know having a quality PSU is key, plus it should last quite a while. Nice features too. Newegg had a sale so I purchased it at the same price as the 550. It came to about $140 CAD shipped with taxes in. I might post some photos of the PC later in the month. Thanks again.

Good choice ☺

looking forward to see the pics
