Hello guys,

I have decided to build the following computer:

CoolerMaster Haf 932 Black Case (RC-932-KKN1-GP)
Asus P6X58D Premium (1366, X58, DDR3)
Intel Core i7 930 (s1366, 2.80GHz)
OCZ Gold Low-Voltage 6GB DDR3-1600 Ram Kit (PC3-12800, 8-8-8-24, Triple Channel, OCZ3P1866C9LV6GK)
INTEL X25-M SSDSA2MH080G2C1 2.5'' SSD 80GB MLC
Gainward GTX275 SVGA (PCI-Express, GS 896, 896MB)


BUT I haven't decided which PSU to buy.

I am between CoolerMaster Silent Pro M600 600W PSU (RS-600-AMBA-D3) AND Corsair HX Series CMPSU-650HX 650W Modular PSU

What is your opinion ? It would be very helpful to decide.

Thank you in advance ! :D

Both are great PSUs. If you plan on overclocking, I suggest you go with the Corsair, just to be safe.

I would get the Corsair 650TX. (In fact I did) It's cheaper, and Modular PSUs can have problems with voltage drops across the connectors.

Thank you Saint19,

To join the community of Tom's Hardware it was a real pleasure.


Please clarify what do you think concerning the 2 PSU I mentioned above. Are too much for my pc or not enough ?

By the way I cannot find the 2 Antec models in my country.

1- Coolermaster don't make very good PSUs (unless it's Real Power Pro series)
2- Take a look of this comparison: PSU comparison, the Corsair is a very good PSU, but as you can see in the comparison, with $20 more you can the get an Antec 750W, that is also a very good PSU.

Also, you can see that don't have ready Crossfire. The good point, is that have 7 years warranty, the 2 other only have 5 years.

3- What is country?

My country is Greece (Europe).
I looked in the most popular e-commerce sites with computer components and I didn't find Antec.

Now, what about the Watts ? 600 ? 650 ? or 750 ?

What is most appropriate for this computer.

Ok, if the e-commerce web page are in English, give me the links to see what PSU are availables.

With a good 600W PSU like Antec o Corsair is enough, BUT if you want install two GPUs (SLI) you need a 650W PSU

That is really sad.

+1. The cheaper PSUs aren't enough for a gaming system, and with the specifications of the rig that he have.

I was refering to the statement regarding voltage drops due to modular connectors.
It has already been shown that there is about as much drop in voltage as there is in 18 inches of wire, in other words, a moot point when talking about high quality modular power supplies.

600 or 650 is good enough, but it hs to be from a reliable company like Corsair or Antec.

Here is a good Antec psu from a site with international shipping:

Hope this helps :D  :D  :D

Assuming you will only run one video card, even 600W is more than you need.
Coolermaster has made a lot of mediocre to crappy PSUs, but the specific one he linked has been reviewed favorably; see my link above.
That said, with the exception of the 430W Basiq, I've never seen a bad competent technical review of any modern Antec PSU (including other Basiq), nor of any Corsair or Seasonic PSUs.

I just came to my office, :sleep: 

Unfortunately the web site is not in English. But even if you don't know Greek (It's all Greek to me ! :o  ) it is very easy to navigate.
Some sentences and words are in English.

If you have time, take a look.

Thank you so much. :)

First of all I would like to thank you all, for your replies.

I would like also to specify that this computer would be for professional use and sometimes I would like to play a couple of Games (Like Call of Duty, Command & Conquer and Football Manager). I don't intend to use SLI. I intent to O.C. my CPU. Probably I would do it from 2.8 Ghz to 3.2 Ghz.


I read all your propositions and I realized that the Coolermaster is not bad it would do the work, BUT is not a Very Good PSU. In contrast with the Corsair is an "All Weather PSU" and it gives you relief that you are in the wright direction.

Am I right ?

Yap :D

Hi again, sorry for my slow answer, but like you I'm not from the USA or Europe.

You can go thi any one of the PSUs of the link.

550W to 750W PSU.

Like you don't want SLI, the 550W PSU is the a very good option for your rig, an support the OC that you want. After that, the 650W HX is the best option. BUT bear in mind that the 650W or more are for SLI or Crossfire.
