How many watts do i need? (Also help with cooling systems)

Savage_1 · Feb 12, 2016

Hello, I am going to build a really expensive PC in May.
it includes:
-12 GB Titan X
-Intel® Core™ i7-5820K Processor
-MSI X99A Motherboard
-2666MHz 16GB DDR4 Powered by Kingston
-System Drive: x2 250GB Samsung 850 Evo Series
-Hard Drive: x2 Western Digital Caviar Black 1TB
-Fans: x2 Noctua NF-A14 IndustrialPPC 2000RPM IP67 PWM 140mm
I intended to get 1000 watts for my power supply but one of my friends said that ill need a water cooling system, i really dont want to get a water cooling system because i saw alot of systems that leaked and damaged the whole thing.
the minimum power supply needed for the Titan X is 600w, so my question is, how many watts do i need without having to get a cooling system, i am really concerned.....
Also if you have any adjustments i can do to the build please share them with me, i would like your help ASAP.

Thank you

Sorry for not listing the case before, the one im getting is a NZXT phantom 410

Drop that titan X unless your just using work programs for gaming you get almost the same performance from a GTX 980ti of about 1/2 the price.
You don't need water cooling but you must list the case for me to recommend one.
You also don't need those fans.

A quality 600-650W will be fine for that system, assuming you're not thinking of doing a lot of OCing (in that case go for a 700-750W). Just get something from Tier 1 (or 2 if you're on a budget) from this extensive llst: http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html

600 is cutting it fairly short since he has almost 400 watts in just the processor and video card. Probably a 500 Watt PC I would get a good 750 Watt. I don't like pushing a PSU real hard and try to buy in the 70% range running a stress test.

Zerk2012 :

A good quality PSU can be run at 100% load (or higher, but I wouldn't encourage that of course!). I usually recommend the smallest possible hgih-quality (Tier 1 from the link above) PSU that can SAFELY be used at ~100% load, since most systems are at (or near) idle the vast majority of the time. Unless you're doing heavy workloads like rendering or are a pro gamer you are sacrificing a lot in the way of efficiency (and up front cost) getting a PSU that is bigger than you really need.

A power supply is not made to run continually at 100% not a clue where you get your information.

Zerk2012 :

The "100%" I stated is for system load, NOT PSU load! I bolded the bit that you apparently missed, but I can see how it wasn't all that clear and I should have explicitly said "system load", not just "load". The PSU size I recommend above is obviously bigger than what is technically needed (i.e. so the PSU is never run at more than 80-90% load under 100% system load conditions - this is what I mean by "safely").
