I wonder why you test a Linkworld unit and not something useful...

I think OEM makes more than you'd imagine.

I don't...
You just have to have a good contract and relationship with the OEM. And you have to pay them decent amount of money for a decent unit.

Remember Solytech? The ones known for pretty shitty units??
The ones that did this interesting platinum unit??

So many manufacturers can do good things, if you want them to...


And for the system builders, some people here said on some occations, that there are way too many out there that don't know shit about what the hell they're doing...
Somethings like the local system builder in your town and so on...

Of course there are some people out there that trust in name brands, to be safe, but there are also many out there that just buy the cheapest shit they can get their hands on...

From what I heard, government agencies and burreaus buy almost only these craps as their only concern is price.

Of course they do!

Because there their success is almost certain, with a successrate of about 100%, why would you spend money on more expansive things, where your success is not guaranteed?!

And with success I mean that they found something that should never have existed ever and violates the law...

With higher prices, the probability, that the manufacturers do decent stuff, rises almost exponentionally...

That Platinum Solytech is only good in respect to efficiency.

That Platinum Solytech is only good in respect to efficiency.

Yeah, for todays standards, that is true...

But for a company that does its first high efficiency thing, who had never ever done something in this area before, it's a really good unit...

That doesn't give this unit a recomendation though, just a bit (more) respect towards Solytech, than before this unit...

OTOH at the 500W level the load table says that the max 3.3V & 5V max power is 230W and the 12V max power is 240W, so that the combined max power at the 500W level is... 470W? Uhm... try again: at the 250W level the load table says that the max 3.3V & 5V max power is 120W and the 12V max power is 144W, so that the combined max power at the 250W level is... 264W?

WOW! That's accurate!

I meant that the unit probably uses a 12A (ultra-)fast recovery TO-220 packaged diode for the 12V rail and probably a 30A schottky for 3V3 and 30-40A schottky for the 5V rail. So accurate in that regard.

Also you forgot to add the 5VSB and -12V rails to the total power, but it doesn't correctly add up even then

I guess it's a long standing tradition at HWI (I mean, dealing with gutless wonders), since Callum was there.

It's much more useful to test stuff like the Linkworlds than all the 1200W and 750W and 850W overkill and high-end PSUs every other site tests and that 90% of people don't need. I'd prefer to see more testing of units in the $30-$40 price range honestly, that seems to be the price point the majority of people are looking for when buying a PSU; yeah, it may be stupid, but you can't always convince them to up the budget.

I wouldn't agree to that.
-Just like in the CPUs, GPUs, mobos etc, you get what you pay for,-performance wise or quality wise-, the same goes for the PSUs as well.
-Logically speaking, if even top-notch expensive units from the best companies have presented problems from time to time (hold-up time issues, transient test response failures, build quality issues, safety issues etc), then you can imagine what the problems could be for the lowest-budget units that are trying to save production cost from every area!!.

P.S.Personally i can't remember a 30-40$ unit that got a good score from a reviewer and i wouldn't even waste my time to deal with a 40$ PSU!! I'm unwilling to risk my PC's longevity to save few $.

Except it's not about what you want to do, for some people it's about what they want to do, and for the majority of people that seems to be a budget-oriented unit. If they can't afford anything higher, then they should at least pick the best one in that price range, which can sometimes be difficult since the majority of units that get reviewed seem to be enthusiast-oriented.
