Choosing a PSU

[Patricek]

So i'm building a gaming pc and i was wondering if you guys could help me figure out if the corsair ATX CS650W PSU is a good choice for my specs. I want to make the right decision since linus said if you buy a higher Watt suply than what you actually need, it can lower the performance of the pc.
 

EVGA GeForce GTX 780 Ti
Samsung 2,5" SSD disk 840 EVO 250 GB, SATA III
Seagate HDD 2TB
Kingston (RAM) HyperX Beast DDR3, 2 x 8 GB, 2400 MHz
Asus DVD-RW DRW-24F1ST, SATA
Intel processor Core i5 4690K
Asus Motherboard Maximus VI Hero, VGA, 1150
NZXT. Phantom 530 White USB 3.0
Antec KÜHLER H2O 1220
Corsair Power suply ATX CS650W

Antec or SeaSonic ...


This is what I recommend.  As for the psu you picked it is good enough to power your rig.

Would you recommend a stronger PSU tho? I don't want to strain it and there for break it in a short period of time.

I found a system on the net that is prebuilt and they used a Corsair 600 watt psu with the 4690K and 780 Ti. 

Question though ..

Do you plan to ever add a second card or other devices to this system?  You may want to choose a different psu if so as then you would not have to upgrade in the future.  

Have you used any wattage calculator to figure things out yourself btw?

[Patricek]

no i don't plan on adding a second card or anything else on this pc. i think it will be good enough. i haven't used a wattage calculator because i don't know how this works

[Patricek]

hmm but maybe i should go for a 850w eh? i'm so confused it wouldn't decrease the performance of my current specs?

Using a higher Wattage power supply than you need won't reduce your PCs performance. It just leaves your wallet more empty than it needs to be. It also gives you room to add more components, in particular another 780Ti.

That CS650M is easily enough.

alrighty then. i'm going with the cs650m, thank you both very much!
