So do you think it's appropriate enough if I get a branded 600W than the 700W?

Heres the thing about power supplies that people keep forgetting when they recommend higher wattage units than are needed. Ideally, for a PSU to reach peak effiency, the system load should be as close to 70 - 90% of the PSU's rated wattage. This is why I recommend a 450 - 550w PSU and that Antec Neo 520 would be perfect because it would put you right where you need to be for peak efficency. Your system, even with a single HD 6970 or similar should not break 400w - 450w unless you do some hefty OverClocking.

 

600w + is going to be overkill unless you really plan on slapping an HD 6990, GTX 580 or higher in there which call it a wild guess but I'm sure you won't be doing.

 

Heres putting it into perspective for you. My last gaming rig was pefectly powered by a Corsair HX 520 for over a year:

 

Phenom 560 unlocked to a quad and OC'd to 3.8ghz

Biostar TA890FXE motherboard

2x 4gb DDR3-1600

HD 6950 1gb @ 980/1300

2x HDD's

1x Optical

7x fans

 

From what I can tell, my last system pulled a bit more power than yours probably will and that HX520 was all I needed and it was an absolutely perfect fit for my power useage.

 

My old system is still in the hands of it's new owner and humming along perfectly and the exhaust from the PSU barely gets warm while gaming. Of course with as many fans as are in that system, nothing really gets warm in it :P

I do not plan on overclocking it since it seems to be powerful enough to play Assasin's Creed III. Yeah, I'm doing this for a game :| . But I am aware of other softwares that are consuming like that Studio Max for 3d. 

 

I only have a fan that works on the Sempron processor. The other is of course from the video card. I have a fan that is attached on the lid but I have no idea how to attach the power supply to it. I cannot see another cable for attachment. 

 

 

I would recommend one of these PSU's over a 700w unit for that setup, even if you do upgrade to a better GFX card in the near future:

http://pcx.com.ph/co...o-eco-520w.html ( spend the extra money and get this one though )

 


 

I guess I'll be going for the Antec Neo then. But the FSP Hexa is still a good deal, right?

Either will be loads better and if you are not OverClocking, even the FSP should last you years till your next major system upgrade.

I forgot to ask about the Maximum Power. 

The TDP of Phenom II x4 is 125W
http://techreport.co...4-955-processor

And the Radeon 6750 HD has 450W power requirement, I believe.
http://www.amd.com/u...overview.aspx#3

Summing them all is 575W. And the motherboard, the memory sticks, HDD, optical drive, and yeah the fans are not yet included. Is a branded 500W viable for this build?

Thanks to your replies especially to wardozerx. :)

....

TDP is not about max power but rather thermals. Your system would only need at max power around 300 watts so the 500 should be fine.

And the reason PSU requirements are so high for video cards is manufacturers prefer to play it safe in case someone does not have a quality PSU.

 

When you have questions about a video cards true actual power draw, do a google ( or bing if you prtefer -.- ) search for "maximum board power" followed by the video card you want to know about. Maximum board power for the HD 6750 is about 115w.

Ok I see.

Looks like I lacked research about TDP. I thought it's like the required power.

I googled about the max board power(and even used Bing). I found out that even the 6850 has a max board power of 127W.

The Bing didn't have a correction feature when I mispelled on the search box. And it suggests less compared to google.
