Why an expensive power supply?

[Shahmatt]

Just to share: My TV rig running on a China board + a 120W power brick.

.

May I know what is this case?

External power bricks follow the Efficiency Level system, which is enforced by EU and USA. It's 80Plus that nobody gives a shot about.

VI power brick (---->) kym?

I am not sure with all the technical and mathematical jargon associated with PSU's but I do know my PSU exploded while gaming last year after 2 years and I got my Corsair HX series PSU exchanged and connected it back. Everything worked. If bad PSU's take out other components when it dies, then simply put, better invest for the lifespan of other components in the PC than trying to save money off the PSU. Essentially, the PSU decides how stable your PC runs and how your PC goes to the grave.

Thanks. I was hoping to buy the Realan W80. Seems like a nice case.

May pair with this board if it fits:

Need to choose a powerbrick (around 150W) to go with it.

Thanks for your reply.

For my case I am trying to make my build small. If I go with a powerboard with laptop style AC-DC 19V adapter I can achieve a compact build. With ATX I cannot have a small build.

However many people look down on these powerboards as inferior compared to full sized ATX.

So I just want to know why. If there is a technical reason I will choose a larger casing to fit ATX size. But if technically there is no problem (e.g - mobo can regulate inferior supply) I might as well choose powerboard.

You may want to try Inwin Chopin it is basically an itx with a flexpsu underneath it,

In shorty

There is nothing wrong with using a power brick to power full PCs
Some will argue that it is more efficient. I tend to believe it so
Just get the power supply that has enough juice to power what you want to build

If you are not sure, just get a power supply and components from a distributor that is convenient to access from where you live.
Eg: If you are getting Corbell Stuff: MSI mobo + Seasonic + Casing. Makes things easier..

PSU is not rocket science, I don't buy whatever plus sh!t. I buy what I need and know what's inside, please don't bother to explain why I need 80plus or 90plus PSUs.

This is the power brick in use since 2011 for this HP computer I'm using to reply here, my admin computer as well as the default computer to run my laser cut machine using Coreldraw and LaserCad almost daily.

This PSU scared the hell out of almost every DIYer:

The innards look scary, doesn't it? Well, its been running flawlessly for the past 15 years since P4 era and finally breakdown last week, after replaced 1 x 100uf 16v and 470uf 16v capacitor, it works again. Now I'm using it as a bench PSU for testing stepper motor, BLDC, sensors and various electronic modules including touch screen and peristaltic pumps etc....

What's so scary about the PSU?

This one made me skip a heartbeat when i powered on. Had a fire extinguisher ready by my side somemore.

The PSU I mentioned earlier is one of the famous "explosive" PSUs that served me well for the past 15 years. I have no less than half a dozen still working faithfully for me whereas other famous brands already failed much earlier than this "crappy" PSU.

Nothing holy about this budget PSU, use it for what it's design for and not trying to push it anything beyond the rating in the label. Treat it as a 200w PSU, you are safe to use it for any basic computer for administration work.

I have a Seasonic AT PSU working till now since the early 90s and never once failed or repair work needed. But, I did have a few much newer model from the same brand failed within warranty period. None of my budget failed PSUs ever took away other component with them but a CM 500w PSU took a socket 462 AMD motherboard with it when it failed.

You can said I'm merely lucky using budget PSUs and taking potential hazardous risk. No issue for me, I know what's inside hence doesn't bother me without the big name.

This power adapter came with an equipment shipped to me from USA, the exterior looks neat and decent. But I can't says the same with the innards.
