what is better

More about : psu hold time 16ms hold time input voltage 264vac full range input voltage 264vac auto range

August 27, 2014 2:38:20 AM

Completely the same. 1 ms means nothing.

But "auto-range" should be better, if it is not just a marketing bollocks.

you wont feel the difference between 16ms and 17ms..
hold up time is capability of psu against electricity brownout..

so the psu CM GXii PRO have 100 Japanese capacitors do it better than gx ii 650w

The GX II Pro units are the same as the GX II units but this time include all Japanese capacitors.

Performance will be roughly same, but Pro unit will be more durable..

and yes, that's a good unit..

The Japanese electrolytic capacitors are of the best quality.

Yes, it is more powerful also. (750 W compared to 650 W).

Well, that is what happens when you don't provide any links, so we can only guess. Yes, Pro version is better.

The performance in the aspect of output power is the same, yes. But, in the aspect of output voltage ripple, Pro is better (lower ripple). Also, since ripple increases over time (due to caps aging), Pro will last longer with ripple within specs.

what is aspect of output voltage ripple and what do it do

It is the AC component of the DC voltage. Ideally, voltage should look like a flat line (in the time domain), but in reality there is also ripple present, so it looks something like this:

http://e2e.ti.com/cfs-file.ashx/__key/communityserver-w...

Excess ripple stresses the capacitors on the motherboard / graphic card / and so on, by heating them up. And since, electrolytic capacitors lose half of their lifespan for every 10 oC increase of temperature...

Also, huge ripple can cause changes in logic states (logic 0 can become 1, and give you errors in CPU calculations).

performance between both PSU is the same..

but gxII pro more durable, that's mean will work longer than non pro series..you can say around 3-4 years longer..

47 - 63 Hz range is better, if you live in a country that has poor power grid. Otherwise, it is the same, since frequency tolerance for power grid are very tight.

I have already told you.

Better quality capacitors, longer lifespan, lower ripple increase over time.

The pro is better. Ripple is basically little dips in the output voltage.
These dips can be either at the AC input frequency (50-60hz) or at the PSU's switching frequency (10s of KHz)
Beside additional wear on the other computer components, ripple can cause instability and crashes.

Best solution

Ripple is probable pretty much the same, but with time it will increase (as capacitors age). Pro is better, because ripple will increase much less then with non-Pro version.

But if you really want a PSU that will last you 30 years, that will heat up very little, and have a very little ripple, buy something like this (resonant PSU):

I can't tell you that without a brand and model of the input and especially output electrolytic capacitors used in both PSUs.

Pro should last over 10.000 hours at 105 oC. For every 10 oC decrease in temperature, lifespan doubles.
This is based on one capacitor that I was able to find out the brand, model and specs.
