Question Please help selecting PSU 850W

[DjPha]

Hi everyone. I am looking for a PSU for this build (No need to Overclock):
** MoBo MSI MPG Z490 Gaming Plus ** i5 10400 ** 32 RAM RGB Corsair (2x16) ** 1 M.2 NVMe 1 TB SN750 ** 2 SSD Crucial MX500 ** 1 Sapphire Nitro RX 6700 XT ** 3 x120mm RGB Fan (came with the Iceberg case) * 3 Noctua NF-F12 PWM * CPU cooler Noctua NH-L9x65.
.

I have used 4 online pc watts calculators and i have obtained suggestions from 550W to 700W (Bronze/Gold). However, some places reccomend to add 100W to ensure greater protection.

Due to the wide range of values obtained, I have selected this options and I would appreciate your advice on the matter.

*** 1) XPG Core Reactor Modular PSU: 80 Plus Gold

Welcome to the forums, newcomer!

I'd pick the Corsair unit among those 3. Having headroom actually benefits you and the build in the long run.

Most calculators are garbage.

GPU full load 250 watts, CPU full load with turbo boost 86 watts, about 80 watts for the rest.
Around 410 watts full system stress test.

Running the PSU at about 60% of what it can do 656 watt PSU.

850 would leave you a good bit of future upgrade room.

I also agree with the above #3.

Edit buy you a decent CPU cooler don't use the stock one.

My mistake. I forgot to mention: * CPU cooler Noctua NH-L9x65 * The case came with 3 RGB fans (2 in - 1 out). I added 3 Noctua NF-F12 PWM (1 in - 2 out)***

Not what I would of got for the price unless their no room for a bigger one but a good cooler for that processor.

Fans and RGB add very little to the watts needed.

Example the NF fans.
Input power (max.)

0,6 W
Input current (max.)

0,05 A

Hey, I'm not an expert but I can vouch for the RM850x that both work flawlessly in both of my builds. My parts require more watts than your setup so you should be golden. I would also be mindful of transient voltages as they can cause your PSU to shutoff. The estimated wattage doesn't take into account transient voltages which from my research is even a millisecond of very high voltage (again, not an expert, don't quote me on that).
