what is better

SO WHAT MAKE THE GXII PRO BETTER THAN GX II

 

[Slobodan-888]

I have already told you.

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

I have already told you.

😀😀😀😀

easy bro..
seems like OP is...mm.. i don't know.. 😀😀😀

so, jhon..please tell us your complete specs..how much is your budget..and..how old are you..? 😀

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.

can you notice the ripple between gxii and gxii pro

 

[johnbennet457]

my spec i5 4440 gtx 670 PE ripjaws x ram 8gb 1600mhz

 

[johnbennet457]

this website said gxii pro have Input Frequency Range 60 - 50Hz

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):

ok thank

 

[johnbennet457]

how gx ii will last and gx ii pro last

 

[Slobodan-888]

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.
