would you take wattage usage from one tool over another?

Hello, 

 

I'm actually having some reboot problems with my very first built I ever done (link at the bottom).  As I'm doing tests about the RAM sticks at the moment, in a chat, real live chat with friends!, somone hinted at the PSU...  So, looking at things, I found the MSI Afterburner alter ego from EVGA: Precision X1.  In short, when I "checked" my system on PC parts picker, it told me that it would be 529W () so, I bought EVGA SuperNOVA 750 P5 750 W 80+ Platinum Certified Fully Modular ATX Power Supply.  However, in the Precision X1 tool, with no overclocking, it gave me a very different number!
 

 

So, here's the question, would you take the Precision X1 number over the one given to me by PC parts picker???

 

Tks in advance!

You put 2 graphics cards in, that's why it's so much higher.

Both of these are kinda off for different reasons. Pcpartpicker doesn’t really take into account some components true power draw, it’s pretty accurate for the important stuff though which is where it matters most. I would trust it most over other calculators, though all are secondary to doing the math on your part choices yourself basing off of reviews and power tests from multiple sources.

 

Evga is just, no. They’re trying to sell you a power supply. It’s a well known tactic most of the other power supply calculator websites out there use, they vastly overestimate and suggest you a higher end psu. Especially evga, which is trying to sell you an evga psu.

A lot of those “can my pc run this” types of websites do this as well, or bottleneck calculators.

Didn’t even notice that, yeah that too.

Still I would never trust evgas psu calc for the above reasons as they sell you power supplies.

the scan process give 2 GPUs because he include the CPU integrated GPU because, no, there are no graphics cards in that thing! lol (I'm not a millionaire for darn's sake! lol)

so, from what I gather from your comments, my PSU should be enough to run the system has is? (with only 1 GPU card I swear!)

The psu is plenty for that system with room to spare for potential overclocks if desired.

Any PSU wattage calculators are just garbage, ignore them. The 3070 has a 220W TDP, expect the system to draw less than 350W under a gaming load. The EVGA P5 is a low end PSU, but the wattage is not an issue
