Single rail can be just as safe if it has protections that are not trash.  You can get single rail PSUs that have per lead OCP instead of per rail OCP.

You act like the price difference between 550 and 650 will make or break a build. 

 

Obviously using an incompatible motherboard won't work. 

 

I didn't say more watts mean anything related to longer life or whatever, only that more watts can't hurt. Can more watts hurt? I would never recommend a 1000w when 650w would do, soo...

 

What system are you using 850 watts for? 

 

Let's do this, what's the minimum PSU wattage you would  recommend for OPs build with a Vega 56? I think if 550w is the minimum you would use on a build like this, than 650 is a safe bet, no? 

 

 

P. S. I like reading your posts and agree with a lot of them. Seriously not trying to argue as you clearly know more than I do about power supplies (among other things)..

That's totally NOT True!

And you also describe a MULTI RAIL PSU in your latter half of the post!

 

Single Rail means that it has a single OCP point or none at all.

If you have multiple OCP points, like you describe, we are talking about a Multi Rail unit.

 

Multi Rail = Breaker in your Breaker Box (just that it switches off the whole PSU if it is overloaded).

Single Rail is what happened in the Link...

Depending on the Unit that might as well be the case!

As higher wattage units with the same Plattform tend to be louder than lower wattage units.

And in some cases you get the same unit anyway, just with minor changes in the Primary area - wich is irrelevant in 230VAC.

 

In other cases you get a louder Unit.

And in other Cases you don't get any benefit at all.

 

Its not as simple as you claim, and there are some serious disadvantages in some cases from getting a higher wattage unit...

Your concept is not reality.  Multi-rail means there are multiple independent 12v power stages, with different FETs driving each.  And its a different thing than single rail with multiple current monitoring shunts.

I have several EPS PSU's that have physically independent 12V rails.  2x for CPUs, 1x for everything else.  If you disassemble a true multi-rail PSU you will find it densely packed with PCB's to fit all of the FETs in the space of the PSU case.

No, that's horse shit.

It means you have multiple, independant OCP channels.

Simple as that.

In most cases, multiple +12V rails are actually just a single +12V source just split up into multiple +12V outputs each with a limited output capability.

No, what you are talking about is multiple 12V or double PSU. Wich are rare and never really common.

He's wrong and why should I trust a random person on the Internet, when the founder of Jonnyguru.com _AND_ Multiple Manufacturers disagree with what you are saying?!

Yes, and?!
Those can be single rail as well...

Having multiple generated 12V Voltages doesn't mean its multi rail, having one doesn't mean its Single Rail.

Could you stop with that nonsense?!
Nobody uses it in that way. So stop inventing your own things.

 

Manufacturers and all people interested in PSU don't use it in that way...

So in short: Multi Rail = multiple OCP points.

The "multiple rail" BS was a marketing campaign to make power supplies with proper OCP sound better.

There are quite a few server power supplies/systems with true multi-rail 12v regulation.

 

The only place where it means what you say is in the marketing fluff "enthusiast" market.

 

I suggest you look up what a voltage or power rail means in EVERY other instance in the EE world.

Here is a hint, it means a voltage output from a regulator.  The term comes from the way schematics used to be drawn with the reference voltages as straight lines at the top of the circuit and the ground as a straight line at the bottom.

Wait the GTX 1660 Ti?

[Type 2501]

I got my hands on a vega 56 to replace a gtx1070 a few weeks ago. End up losing the lottery. And don't forget The power limit without any mod is already 250w when you set to +50%. There is in fact a price to pay to oc the vega hard. Pushing any more voltage to the core might not be the most effective way to get more flames from the card even you can cool it.

 

And using a evga B3 650w, the coil whine is quite bad when loading up some game.

 

All in all a fun card to OC with (except you have to flight with wattman), but not necessarily the choice if you want to just plug and play.

Dude. You obviously didn't read the post. The OP's max budget is $375. Get your head out of the sand.

It's totally out of his range now, I've seen them sell as high at $1,130.00
