Is there some truth to this?

Some dude told me that if you use a high wattage power supply with, let's say, a micro-atx or itx motherboard, the power supply'll fry the motherboard. Now, is there some truth to this or is it just some mumbo jumbo inexperienced IT guys say?

That is 100% false.

Yeah, it's frankly just bs.

Why, when we have robust standards in motherboards and power supplies in regards to what kind of power we use in a PC, would a PSU, any PSU.. High wattage or not, blow up a motherboard (be it mITX, mATX or anything else)?

It's just untrue.

 

A high wattage power supply won't just take more power from the wall, just like a lower wattage unit is will only takes as much as nescecary (keeping in mind a power supply is of course not 100% efficient).

Of course buying a terrible power supply, regardless of what wattage it claims to have will be a bad idea.

This is a super old rumor, I'm surprised it's still kicking around 

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

that is like 400% false... thats lacking a basic understanding for electronics and power in general

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

Builds:

The Toaster Project! Northern Bee!

 

The original LAN PC build log! (Old, dead and replaced by The Toaster Project & 5.0)

It's not like the power supply pushes power to the parts. It's the parts that pull power from the power supply. Only as much as they need. 

 

Edit: Actually let's go with this logic for a while. Let's assume high power PSUs are like strong fire hydrants, and they need a wide hose not to damage it. Even if that was true, why would the motherboard *form factor* determine if it's safe or not? Size of the motherboard doesn't dictate how much power the processor or graphics card consumes.

It's false the PC only pulls what it needs from the PSU no more no less though don't get a cheap PSU though as they could fry everything

I still don't get why he said "oh that mobo is pretty small the psu'll fry it". Like who in the right mind would say that? Look, I'm not that experienced when it comes to PCs, but I just had to confirm what he said because of how unbelievable it sounded.
