Purchased a Corsair HX750 PSU.

Background:

1. 1st build.

2. 3 mos. ago minimal computer knowledge. Went from learning what wi-fi and Bluetooth is ---> challenging myself to do a build.

3.. Will be basic home PC. Mainly file ( pic and home video storage ), with possible gaming. Nothing crazy....?


What I have so far:

i7 4790k

gigabyte Z97X gaming 3 mobo

Noctua NH-D14 fan/heat sink

Crucial Ballistix ( sport) 16gb RAM - 2 x 8gb sticks

Corsair AX 750 PSU

LG Blu-Ray internal optical drive w/ burner and BDXL

Samsung 500gb 850 PRO SSD

Internal card reader (don't laugh)

Corsair 760T case


What I still need to get:

HDD - for file storage

Another larger External HD

OS _ Leaning towards Win 7. We have 8.1 -HATE it!!!

Will more then likely upgrading my exhaust fan

Would like to add an additional fan on top or underneath HDD or HDD cooler case/fan

GPU- Want to run 3 monitors. Nothing crazy like 4k or too insanely expensive. Mainly because we have lots of windows open ( online ) @ a time.
___________________________

I posted my specs. and needs in a prev. post and got a lot of comments that my PSU is an overkill unless I am doing gaming with a serious GPU. I do intend to purchase a nice GPU. I probally wont need it, but its nice to know I will have a powerful GPU in case I ever need it down the road.

Is there anything wrong with having this PSU that has more power then I need? Will it affect the performance of my machine if this is more then I need?

If the answer is yes. By adding a GPU will that help accommodate the power that is left?

I did purchase this big PSU because I thought it would be ncie to know I have the extra power if I need it in the future? Wrong mentality? Should I return?
 
A power supply will only pull as much power as it needs. If you have a system that requires 300 watts to run and use both a 400, a 700, and 1200 watts PSU in it then it won't matter which you use, all 3 will just pull 300 watts. You can never have too much, but you can definitely have too little.
 
There is nothing wrong with having a power supply with that much wattage. The system will only use as much as it needs. With 750 watts you will be able to get a very good single card such as an r9 290x or gtx titan Z. So if you won't be doing any very high end gaming then yes, its overkill.

Thank you for the response. That brings up my other ?
NVIDIA, ATI and AMD

Which is compatabile with an intel i7?

I thought certain GPUs will work with only certain brand CPUs?
 
You can use anything you want.

ATI is now owned by AMD so its only AMD and Nvidia now.
 
It's only 'too much' since you could have used a lesser wattage unit which costs less and your build would have still been plenty good.

I have a 1600w PSU in my build but none of my usage even comes vaguely close to that. As above components will pull whatever amperage they require. You only really run into situations if your PSU is failing/defective and putting out too high of voltage, or if you don't have enough wattage to support your components (leading to instabilities and crashes).
 
So let me get this straight.

All video cards can be used with intel i7?
AMD graphics cards can be used with intel i7?
NVIDIA graphics cards can be used by intel i7?

Depends on what you want to spend. I'd get a GTX 970 personally.

Guy @ Microcenter rec. the 960.
I don't mind spend close to or slightly over $300.

What would the benefit with a 970 be over 960?

I see that the 960 is 2gb DDR5 and 128bit?
The 970 is 4gb DDR5 and 256 bit? or something?

The 970 has more vRAM, which games are starting to use more and more of these days. It's also 1/3 stronger than the 960.

And to answer the first question:
Yes.
Yes.
Yes.
Don't know what makes people think otherwise.

You can use any PCIe video card with whatever processor you want. (There are exceptions, such as new GPU's with old processors causing bottlenecks, but there is no need to get into that.)

thanks so much. You've educated me a lot already. Im not sure where I thought certain brand cards could only be used with certain CPU companies

Maybe I should start another post on GPU basics?
What is the difference between AMD and NVIDIA?
I see some are models 900's and come r 200's?

Im clueless
 
The numbers are just model numbers. Each series has a higher first number (GTX 4xx, GTX 5xx for nVidia. HD4xxx, HD6xxx, R7, R9 for AMD). The second sets of numbers indicate the range of the card (GTX 560 is weaker than a GTX 570 for example, and similarly it goes for AMD that way).

AMD cards cost less and are purchased when you're looking to build more affordable. I had several AMD cards (HD4870, HD6870) and they were alright, but I don't care for their drivers. They can be a bit buggy sometimes.

nVidia includes a special chip on their card known as PhysX. It adds real-life physics to elements of the game. Not all games have it though. nVidia makes some of the strongest cards out there, but the price is normally pretty high. Their drivers are always stable.

Here's a good PhysX example:

The PSU is fine. You can never have too much power. I don't know if I would spend $300-500 on a GPU "just to have".

I'm not trying to be a knucklehead, but I would suggest you do some reading and gain some knowledge. I research the heck out of everything before spending my money. Magazines like CPU (Computer Power User) are great sources. One of their issues last year had a 10 page review on building your computer and what to do when the first boot goes wrong.... better be prepared for that. I've been building for years and running into problems on first boot is not unusual.

You started this thread because some people on your other thread said that you have too much CPU. It is already bought, so it isn't too much CPU. If it was the other way around, then you could bet you would need a different one. You also decided that you would rather use Win 7 instead of Win 8 because three people on your other thread say they hate Win 7. Again, I suggest a little research on your own. You have picked out good parts now learn what they do and more importantly how you are going to get them to work in your new build. The small stuff will get you like not making sure your motherboard came with SATA cables and finding out that your SSD and Hard Drive, and DVD burner also didn't have them in the box. 90 degree SATA cables can be a life saver. People finding they don't have the right cable for the monitor and GPU is another common problem. If you decide to buy that MSI GTX970 you will find that it has connections for HDMI, DVI, DVI-D, DisplayPort, and VGA. I prefer DisplayPort when the monitor/monitors can support it.
