Question 750 Watts good enough for the system?

Cem Goker

Jul 3, 2013
Hello guys! I will be building a PC this month or the next, and I already bought/own most of the parts. Listed below are the parts I have bought so far:

Motherboard: Z490 Aorus Master
RAM: Night Hawk RGB 16GB (8x2) 3200 Mhz
Cooler: NZXT X73 360mm AIO
PSU: Seasonic Focus GX-750 Gold 750 Watts Fully Modular
Storage: WD SN750 M.2 Nvme SSD 1TB
Samsung 860 Evo 500 GB SSD
Samsung 860 Evo 250 GB SSD
Western Digital Blue 3TB HDD
Case: Lian Li O11 Dynamic Black
GPU: ASUS Strix GTX 1080 8GB OC

Now I plan to buy the i7-10700K alongside the RTX 3080 at the end of the year, and I worry that my 750 Watt power supply won't be enough to overlock my CPU/GPU(not too much on the GPU) for gaming purposes. I plan to overclock the CPU to 5.1 GHz with a ring ratio of around 48x. I watched some videos from GamersNexus and also played around with the PSU wattage calculators from Seasonic and Outervision, and they all point towards an 850 Watt power supply recommendation (with an RTX 2080 Ti on as a means to calculate the graphical power of the next gen cards).

So what do you guys think? Should I buy an 850 Watt version or just stick with the 750 Watt?

I would play it safe and go for the 850 watt PSU. 750 would probablly break down under the massive stress of the components, even more so if OCd
