450 or 500 Watt?

[Md. Mahiruddin Bhuiya]

For my AMD Ryzen 5 1600 and a GTX 1060 Mini 3 GB, should I opt for a Corsair VS450 or any other 500 Watt PSU would be better?

450W is plenty, but the VS is crap. The Pure Power 10 400W, CX450/M or Vengeance 400W shouldn't cost much more.

Also bear in mind that as PSUs age their output ability can degrade.  Also the further from their maximum load, the less heat they will produce and the capacitors will last longer, potentially increasing its life span.

The VS isn't a good unit. That system will draw maybe 200W under load though. A Corsair CX450/M or Cooler Master MasterWatt would be a good choice.

Thank you very much for the information. I just checked your tier list. It enlists the CX series and VS grey units as the same.

My budget is limited so, I can't go for any semi modular choices. So, instead of a CX450M, can't I opt for a VS550 "grey" unit at a much lower price?

Anyway, I just checked for the Cooler Master MW450. It's just a tad more expensive than the VS450 orange one while being on a higher tier. The list was really helpful.

Get a CX450 they are very good

The old CX is on the same tier as the new VS. The old VS is lower on the list. The new CX is on T3. That unit is leaps and bounds better.

No, that's a fairy tale.

I haven't found any evidence for that claim!

And I looked for days.

 

And the ones I've found seem to debunk it and out it as bullshit.

 

For example:

https://www.computerbase.de/2013-11/alte-netzteile-test/

 

Others are the HardOCP Tests that come from time to time. 

So PSU don't loose power! And also they don't degrade that much as well.

And how the hell is that claim compatible with the laws of thermodynamics and energy conservation?!

Heat produced is Pin-Pout. That is the loss.

 

And the only factors for that are efficiency and load. If one is at 90% and the other at 25% is totally irrelevant, the heat produced is the same.

 

As for the Capacitors: Look at Bitfenix Whisper M, maybe Formula. Or be quiet Pure Power 10.

They all have the same capacitors on the secondary side!

So your claim is bullshit.

both are crap, get a decent quality PSU like Bitfenix Formula, be quiet Pure Power 10 (400W and up), something in that Price Range.

And do not save on Money.

 

As for the GPU: I hope you haven't gotten it yet!

Get an RX470 or 570 instead. The 8GiB Version of course. As the 3GiB 1060 is totally crippled and the Memory is an issue today.

4GiB is the bare minimum but should be avoided if possible, 8GiB is preferable.

"Losing power" is a simplified description.  The actual issue is as the capacitors age their capacitance reduces, and the more current you are pulling the more likely their lower capacitance is to cause instability.

 

As for using a much higher rated PSU than needed its a similar principle to using a bigger CPU cooler than you need, its more efficient at getting rid of the heat.

Bigger heatsinks, more efficient designs, capacitors rated for a higher operating temperature, so if you run them well below their rating they will last longer.  Its the simple fact that for a higher wattage PSU they HAVE to use better components for the reason you described, they have to handle more heat!

 

Even if the capacitors are the same, its likely the rest of the unit has been changed to better remove the heat.  Obviously it varies, there may be little difference between a 400W and 500W.  But a 400W and a 600W I would expect some changes.

Doesn't make it right...

Look at the review I posted.

Look at the Reviews of 10 Year old PSU on HardOCP.

 

Your claim is just not true.

Especially since we are talking about stuff like 20mV Ripple usually or lower. Even with double that its not a problem.

How the hell is that possible when 2 PSU have the same heatsinks, the same layout, ~the same efficiency?!

Again, its bullshit because it violates the laws of thermodynamics...

 

And in some cases they put a faster spinning fan inside. Look at the EVGA G2, G3 and P2 units!
The 850W is really freakin loud once the fan starts. the 550W is OKish.

For example:

https://www.hartware.de/2012/11/27/be-quiet-dark-power-pro-10-650w/8/

And I've seen the Fan speed from one vendor where the ~550W is good, ~650W is garbage, ~750W is OK again.

So no, repeating a false statement doesn't make it more true.

Again, you assume things without evidence.

And that is your problem.

Just look at Bitfenix Whisper M or the other ones I've mentioned.

 

Take this for example:

Now spot the differences and point them out!

 

 

So what you are claiming is just not the case in too many cases and you must not generalize it and look at each individual unit.

Surely if the designs are identical the fan would have to handle the greater heat output?  Is that not likely to reduce the operating temperature or at the very least gives you more leeway for cooling if your room temperature is high thus maxing out the fan speed on the lower unit?

 

I can see how there is clearly not a "one size fits all" guideline though.  Honestly, finding a good PSU is a PITA and clearly its best I avoid giving advice at this point.
