I'm choosing my power supply based on using half of the wattage for optimal performance. Is this a foolish approach? What values are you considering? I'm using PC parts picker, which lists my build at 428 watts maximum, aiming for an 850W PSU. Are these figures correct?

The additional RAM is intended to achieve the required wattage for the calculator. This is why it's configured at 0.00 price. The item being referred to is the RAM I wish to purchase. The teamgroup is relevant for the wattage information.

This doesn't make sense.
Real components. Not a fabricated list.

The actual components you wish to acquire are listed here. The 9600x option will be either a 9600x or a 9600x3d, based on availability.

It looks like you've chosen a more practical option rather than the higher 8000 MT/s RAM speed. What makes sense is opting for 6000 MT/s instead. Why would you prefer two sets of 2x 16GB? Merging two distinct RAM packages isn't ideal, even if they appear similar. Check this out (second chapter): https://forums. That sounds like a silly idea. Power supplies work best when the load stays between 50% and 80% of their rated power. It's not a fixed percentage. So, why do you feel this way? Also, the term "max usage" is too vague; it's hard to adjust precisely to a single watt. In everyday use, CPU and GPU don't run at full capacity together. Usually, one dominates the other. Only under artificial conditions—like running Cinebench and Superposition simultaneously—can you hit 100% utilization for both. But that's not a typical scenario. If you overclock the CPU or GPU, power consumption changes: it rises with overclocking and drops with undervolting. Since we don't know your plans for the build, we can't accurately predict the exact power draw. We can only give a general estimate, like around 395W for the CPU, 180W for the GPU, and about 150W for the rest. That's roughly 650W total. Adding an OC would push it to about 65W, while 750W is a bit too high. An 850W unit would be excessive.

The RMX 3.1 850 watt is an excellent power source. I recently upgraded mine using this one.
Typically, I recommend a 1000 watt unit if the cost is reasonable, providing extra flexibility in the future.

Considering a 2.8kW unit would provide extra capacity for future needs, wouldn't it?

It worked out. I switched the system to a 9800x3d and a 5080. 850W allowed me to upgrade to better components. 8)

I'm thinking about boosting two PSUs to 1000W or 1200W to check if it helps with stability during extended video transcoding sessions. I've found that sudden current spikes on RTX GPUs can cause PSU OCP in certain cases.
My current units are older ATX 2.0 models and not the newer ATX 3.1, which might mean OCP activates at 130% overload instead of 200%.
If I limit GPU power to 95% in MSI Afterburner for my RTX 3060 and RTX 4070, I should see faster renders—potentially saving 30 minutes to an hour on long jobs.
Although the systems use about 100W each when idle, which is efficient compared to most PSUs, I’m more focused on stability than efficiency.
So far, I haven’t pushed power ratings too high, but I’m considering adding another 300 to 500W headroom just in case of larger current spikes.
