Hello all, I'm not going to write a lot of intro. For my first PC build, I am looking for a right power supply. All the power supply calculators are unreliable and give me different answers, so I need some professional answers. Money does matter, so let's keep it low, but great quality. If a great power supply is $75, please suggest it (or whatever you pros suggest!) Also please do not hesitate from give advice or constructive criticism for any parts of my first gaming pc build. Thanks all !

Thanks all, seems like I won't need more than 750W. Better safe than sorry. Better to buy more than less. Again, I'm a beginner, what is the overclocking?

Overclocking is changing settings on your hardware to get more performance out of them. It can be very easy or very complicated and takes a lot of time, research, and TLC to do it properly. If you don't know what it is I do not recommend you attempt it without spending plenty of time learning first.

That said you do not need 750w. Even if you choose to OC that is likely necessary. Save the money and get a Seasonic 550w-650w gold/platinum PSU and use the extra $$ to get a better GPU, even if it is just an upgrade on in the GTX 960 line. FYI I use a 450w bronze SFX (small form factor) in an almost identical ITX build, it's overclocked and it has no problems at all.

System Power Supply Requirements for a single GeForce GTX 960
• NVIDIA specifies a minimum of a 400 Watt or greater system power supply. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
• the system power supply must also have a maximum combined +12 Volt continuous current rating of 29 Amps or greater
• the system power supply should also have at least one 75-Watt 6-pin PCI Express supplementary power connector. There are some non-reference design cards that require two 75 Watt 6-pin PCI Express supplementary power connectors (e.g. Gigabyte GTX 960 G1 Gaming 2 GB [GV-N960G1 GAMING-2GD REV.1.0], Inno3D iChill Geforce GTX 960 2GB Ultra) or one 150-Watt 8-pin PCI Express supplementary power connector (e.g. EVGA GTX 960 SSC 2 GB [02G-P4-2966-KR], MSI GTX 960 Gaming OC 2 GB [GTX 960 GAMING 2G]).

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

EVGA SuperNOVA 550 G2 (220-G2-0550-Y1)
• OEM: Super Flower
• maximum combined +12 Volt continuous current rating: 45.8 Amps <===== Way more than sufficient
• one 75-Watt 6-pin and two 150-Watt (6+2)-pin PCI Express supplementary power connectors <===== More than sufficient
• Ambient Temperature Maximum (i.e. without derating): 50°C
• Full Modular Output Cables: Yes
• Passes Official Intel Haswell Compliance Test: Yes
• 80 PLUS GOLD Efficiency Certification
• 7 Year Limited Warranty with registration
