Unusually Cheap Power Suplies

[Brennan808]

I was looking for a power supply and found this https://www.amazon.com/gp/product/B01N9X3F8F/ref=ox_sc_sfl_title_1?ie=UTF8&smid=ATVPDKIKX0DER&th=1, its only $22 and it looks decent. Am i missing something?

Isn't that normal? Never really went into depth with gpus.

No thats a normal pice for a 450W PSU

IIRC, EVGA was caught cheating on the life-span of their power supplies.

I have one (this was before I knew) and I'm not impressed with it, It works, but I fear if I push it too hard it will fall over.

If you are not using a heavy GFX card, then it should be okay

No this will be a system that will run 250w tops

It has a 3 year warranty, if smth goes bad he can just return it.

then you should be okay with it

It will be all right, its by evga and it's all u would need then, just don't cheap out even more on power supplies, that's a very bad idea.

Not all EVGA's power supplies are good, some(quite a few actually) of them are junk.

yh, this one has a warranty, if its bad he can return... But if its rly bad it can do some bad stuff to the machine. The reviews say otherwise.

They're user reviews. They don't mean anything as they don't use a load-tester.

It's cheap as it isn't really great, though not much is known about it. http://www.jonnyguru.com/forums/showthread.php?p=138334

 

What are you powering?

[turkey3_scratch]

So much wrong info.

 

Firstly, those 3000 user reviews aren't for that specific PSU. They are reviews for all EVGA B1, B3, B2, BQ, and BT power supplies. All of those, of all wattages. Pretty stupid how that works huh?

 

Plus those people aren't professionals, they have zero authority to say anything about the power supply other than it turned on and maybe how loud it is. There's a lot more to PSUs that just turning on.

 

The EVGA BT is going to stink. Any $22 PSU is going to stink. The price is enough to tell you that. If your computer is super cheap, then a $22 PSU like that may be acceptable, but I'd rather spend $40.

Don't listen to Amazon reviews for power supplies. Turning on is not indicative of PSU quality, you are very misled in your beliefs about judging PSU quality from Amazon reviews.

Yes everything.

Ever heard of the saying: "If something seems to good to be that's because it is"??

 

Such cheap shit is most likely unsafe to use and can kill everything its connected to as well as its user, they have to take every shortcut there is to be able to get to that pricepoint and use the cheapest/worst components they can get their hands on. 

 

There is also another possibility with big companys:
They can work with very low margins, if at all.

 

So no, you should not buy it and get something decent...

It's not any good, but you can't complain or expect quality at $22. For a secondary system working a low load (especially if you don't run high ambients) that you don't care extremely about, or maybe to revive an old system with virtually worthless parts, it may be a value pick worth some consideration for the cash-strapped. Now, if you have the money for something better, go that route.

 

I mean, it's probably a good step above true junk and complete frauds that can't do the rated output under any conditions.

I'll just go with a "Do as I say, and not what I do." approach and recommend looking for a known-reputable PSU (not just the brand alone). If you can get any of the top few tiers in the PSU tier list within your country, you should be just fine. 

 

As testing these things requires equipment very few users will ever have, user reviews are not likely to tell much of the story on a PSU.
