Mind you i dont play games on my computers so i dont need a high end video card.
Then you don't need anywhere near 750W for a PSU. And while the PSU is arguably the most important purchase decision you will need to make with this build, it really should be the last decision, after you have decided on everything else and determine what you actually need for power, especially with the chosen graphics solution.
What will this computer be used for? There are very few programs that can take advantage of an 8-core processor. Even most games don't. Unless you will be doing extreme 3D CAD/CAE (designing bridges, skyscrapers, or aircraft carriers)or CGI work (Disney's next animated movie), most of that processor will be sitting around doing nothing. It is most likely just a lot more CPU than you need. The
FX-4350 gives you a little bit faster base speed of 4.2GHz speed, but as a nice quad core processor for less than 1/2 the price. The money saved can go towards a better graphics solution, more RAM, better SSD or something else.
Back to the PSU. I highly recommend the use of a good PSU calculator instead guessing or arbitrarily picking a size. And IMO, the best out there is the
eXtreme OuterVision PSU Calculator. Note that all PSU calculators typically pad the results because they sure don't want you to buy too small a PSU. But this calculator is much more flexible so it can be and is more conservative than the others - a good thing because it does not go overboard with it recommendations.
Using that more hungry FX-8370, bumping up CPU Utilization to 100%, adding 1 SSD, 1 HD and 1 Blu-ray drive, and 3 x 140mm case fans, increasing Computer utilization to 16 hours per day, and lastly, inserting the very power hungry GTX980Ti graphics card (which you do NOT need), you can see
here that a good 600W PSU will be more than you need. Note by increasing the CPU and Computer utilization above the recommended defaults, that adds even more headroom to the results to allow plenty of room for possible future upgrades and additions. At the default settings, a decent 550W supply is plenty for you, even with that extreme graphics card.
Since you already said you will not be gaming, no way will you need such a power hungry graphics solution as the 980Ti. So a 550W supply will be more than a enough. I have the EVGA Supernova G2 550W in this system (i7 quad, 16GB RAM, 2 x SSD, Radeon R7 370 OC). The only problem I have with this PSU is the fan is so quiet, I cannot tell if it is spinning unless I stick my ear up to the back and "
feel" for the air movement! :grin1:
Note that most people would be surprised to find out how little power their modern computers actually use. I have my computer, all my network gear and TWO 24" monitors plugged into my UPS which has a nice power status display panel and I am currently using just 123W (which includes both monitors!).
It would not hurt to get a 750W supply, but you would be wasting your money.
