Info Newegg's "PSU calculator" is garbage

[AnitaPeterson]

I don't know when (or why) but it seems that Newegg have turned their PSU calculator into a joke, with the sole purpose of making money off naive customers.

I'm preparing a system for sale and I just wanted to calculate the necessary PSU wattage... And I discovered that, while every other site that offers this calculating service is making an effort to be as precise as possible, regardless of whether they're OEM manufacturers (like FSP, bequiet! or Cooler Master) or general information portals (WePC, OuterVision), Newegg is now just using this to peddle absurdly oversized power supplies.

Case in point: the build is mid-to-low tier (Ryzen 1600x, mATX, 16GB DDR4, GTX 1650).
I barely entered the CPU and motherboard format, only to see that Newegg suggested "400 - 499 Watts".
The whole rig is pegged at "600 - 699 Watts", once I add every detail.


Meanwhile, all the other sites calculate a more reasonable load value of around 320W, recommending a 370W PSU for a safe margin..


Stupid and disappointing.

Having done a few systems I eyeballed this at 400 and would do a 500 for breathing room for upgrades. Personal baseline though is 850 just because you never know if you're going to throw in an rtx or not. PCPartPicker is usually pretty accurate though.

Possibly they're doing it because they're still selling cases with crappy, overrated generic PSU in them?

I used to get some Corsair 430W for ~250W systems but mostly because they were dirt cheap after rebate. Otherwise, my minimum on a full sized would be 500W and even then, bump it up to 600W-750W if the price difference isn't much for the same tier of PSU.

Overshooting helps to increase the lifespan, though that is countered somewhat by more aggressive fan throttling in modern units so if at a lower % of total load, just spins the fan slower so it still gets warmer, but at least quieter and less dust buildup if it's not a filtered case set up right.

Newegg (and other retailers) sell some really crappy power supplies that can't even come close to outputting their stated wattage.

I'm sure they don't want to deal with a bunch of returns, so it's safer for them to grossly overestimate what is needed "just to be safe".

I can fault Newegg with plenty of things, but this is a smart move on their part.

In the last few decades Marketing has shifts to be dominate by people with very flexible verbal skills rather than any understanding real Technology.

A good example for it is the WIFI marketing. It is based on the manufacturers rating of the core chipset alone. However the real WIFI usefulness is an outcome that depends on many other variables (like other components of the circuits, quality and placement of Antenna, general electrical noise of the environment, and more).

So.. advertising that my WIFI capacity is the rating of the core basic chipset is actually “”Cheating””

Same is for most other integrated components involving computing Hardware. The total functional Wattage of a PSU Not just the rating of the core capacity of the unit’s components.

In reality it is recommended to compute the amount of Power that the total computer needs, and then buy a PSU that is rated double the Wattage. I.e., if the components need 300 watt buy a 600 watt PSU.
