XFX PRO 650W fully wired VS CORSAIR TX650 vs SEASONIC S12II-620 BRONZE 620W

alch3m1st · Oct 24, 2013

XFX PRO 650W fully wired has 1y warranty
CORSAIR TX650 has 5y warranty
SEASONIC S12II-620 BRONZE 620W has 5y warranty

In my country are at the same price.

Which is better?
Which is more silent (I saw corsair has a special mechanism not to spin fan if not under load) ?

Any other suggestions?

not gonna crossfire/sli

The SEASONIC S12II-620 BRONZE 620W for a bit more in price.

What is the exact model number on the TX650? Some of them are made by seasonic. The XFX pro is also made by seasonic. Very nice PSU's. Assuming the TX650 is one of the seasonics, I'd go with the TX since they are offering the full warranty. What country are you in?

alch3m1st · Oct 24, 2013

this is the discription "CORSAIR TX SERIES TX650 - 80 PLUS BRONZE CERTIFIED 650W HIGH PERFORMANCE POWER SUPPLY". Does not say model number.

I am from Greece.

There is also a seasonic (I edited my question so you might missed it.)

All three of those power supplies are of great quality. You can't go wrong with any of them. From the information you have given, I'd take the TX650 since it has the full 5 year warranty and it is cheaper than the seasonic S12II.

alch3m1st · Oct 24, 2013

Seasonic is 12 dollars more. Do you know which is more silent? My PC will not be under load most of the times, since I rarely play games

Corsair actually replaced the TX series with a newer lineup called the RM Series, and they are designed to be extra quiet. How is the pricing on the Corsair RM models?

alch3m1st · Oct 24, 2013

CORSAIR RM550 is 27 dollars more than the CORSAIR TX650
CORSAIR RM650 is 41 dollars more tha the the CORSAIR TX650

Are the RM that less noisy?

Are the TX and S12II noisy?

jimthenagual · Oct 24, 2013

The TX650 has a 140mm ball bearing fan, and the Seasonic S12II has a 120mm ball bearing fan. I wouldn't expect either to be too loud, but typically the larger then fan size, the quieter the PSU. The TX650 is looking like the better choice.

With the RM, that is one of it's selling points. They specifically focused on making a quiet PSU.

What about all the people here saying about the ultra quality of the seasonic? I saw that new TX will are manufactured by Channel Well. Am I being obsessive here?

jimthenagual · Oct 24, 2013

That's why in the beginning I was asking you for the TX model number. Some of them are made by Channel Well, some of them are made by Seasonic. The CMPSU-650TX, and the CMPSU-650TXV2 are made by Seasonic. But even CWT can make some high quality PSUs. True, they make the CX which are entry level, but they also make a lot of the HX lineup, and they've received excellent reviews from testers.

And yes, it is good to be obsessive, you are about to spend some good money!

I have seen numerous videos on youtube from people complaining about tx 650 noise:

even for the seasonic:

anyone had the same experience? anyone has anything else to propose?

Sangeet Khatri · Oct 24, 2013

They all are very high quality power supplies, so go for the one which is cheaper. All three are equally fantastic power supplies, so you would be good with either of them.

Hence just go for the one which is cheaper.

alch3m1st · Oct 24, 2013

I understand they are nearly top quality products, but I don't know if they are noisy (anyone owns one of these maybe or know a site having a decent review?) or if I have any other alternatives at that price.

Sangeet Khatri · Oct 24, 2013

Well.. you can always look out for their reviews online. There are tonne of full detailed reviews online. Anyways Corsair Seasonic and XFX (PSU's made by Seasonic) always use top notch quality components, so I highly doubt that either of them would be noisy.

But talking about the best of them, the Seasonic one is used by a lot of people and it has positive reviews all over the Internet, so I think that it should be just fine for your needs.

Anyways if low noise is your priority, then go for the Corsiar RM series PSU. Some quality of them are :
1. 80 Plus Gold certified.
2. Completely Flat Cables for easy cable management.
3. Extremely low noise, near silent.

alch3m1st · Oct 24, 2013

Any other affordable silent PSU model?

Sangeet Khatri · Oct 24, 2013

These three are good enough.

alch3m1st · Oct 29, 2013

After a forum post an the net from a user that experience noise with the XFX and after seeing numerous youtube videos and forum posts about CORSAIR TX650 noise problems I will go with BE Quiet! 630W modular.
