I am finishing up my computer build and needing to know what PSU would be the best of these two.

My Rig is made of this:
NZXT Alpha Case
Intel Core2 Quad 2.83GHz Q9550
OCZ Fatality 800MHz 2x2GB
HIS HD 4850 ICEQ4 Turbo 512Mb
WD Cavier Black 500GB 7200RPM Sata
LG DVD/CD Burner


So, these are the two PSU I am currently looking at.

Corsair 650W

OCZ StealthXStream 700W ATX12V/EPS12V
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Just let me know what you all think, I know either one will give me plenty of Power but I want to be able to expand without worrying about having the power to run it. I want the PSU that will last me for the life of the comp if possible too.

Thanks ahead of time.

+1 for the Corsair 650TX...It has enough juice even for 2x HD 4850...

And just a heads up on the HDD...If you havent bought one already, then get the WD BLack 640GB instead of the 500 as the 640 ones are newer, faster and more efficient than those old 500GB ones...

i would get the seagate .12 500GB or 1TB drive.

I would say you dont even need 650watts...looking at your build, a solid 500w or so will do...if you plan on going crossfire later on, 650watts is pushing it and therefore you would have to upgrade your psu...

^ That Corsair 650TX can power 2x 4850 without any issues whatsoever...
Actually if you check the TOMs recent article on the cyberpower dragon rig, it has an o/c X4 955 + 2x HD 4890 in crossfire, running on this Corsair 650TX...

Corsairs are very conservatively rated. Most other manufacturers would sell the 650TX as a 750 watt power supply.

I would rather have Western Digital over Seagate because of their wide known success and reliabilty. I was thinking about getting the 640GB but it will all go down to do I have enough money for it. That's why it is a budget build and all, lol. But, I do know what your saying about getting one.

Any other info would be very much appreciated.

its all about the components inside the casing. corsair's 650tx has Seasonic parts in it if im not mistaken. which is about the best you can get.

while the PSU is rated at 65o watts, the amount that the 12v rail "think of it as a circuit breaker" is rated for 52Amps (watts=voltage*amps) thus 624 watts out of it.

at the same time, the 5v rail is rated at 30 amps= 150watts. which means that it could really count as an 800 watt PSU

corsair likes to market their PSU's more off of what their 12v rail can output rather than totaling all wattages like other manufacturers

well in case if ur looking for a cheap and double best psu for ur requirement, i agree with gkay09 and i recommend zebronics 700 watts platinum series optimized for sli,crossfire...its only about 80-100$ the brand may be crappy don't worry about that but the product is just damn good...

Definitely Corsair. +1

Nice link from xbit labs in re: PSU requirements...

http://www.xbitlabs.com/articles/coolers/display/system...

So both of the PSU's you have selected will be massive overkill for your present, or conceivable future, uses.

The above being said, I prefer Seasonic PSU's. Good reviews can be found below:

I see some of you saying incredible overkill and some saying that for my future wants, it would be great. Thanks for all the words so far.

Here's my final question at the moment;
Which PSU do I need then that would give me absolute safety, so that I can expand more plus have plenty backup Watts?

Thanks!
July 9, 2009 2:00:01 AM

I should have said Need but the main thing with me is not only safety.......but DURABILITY!!! I want my money to go for the long haul if you know what I mean. Not a person that will go and spend money on every new part that comes out there, and I want spend it just to try something out unless I know its a huge upgrade. I guess most people are this way as well. So, I want the most durable parts, other than maybe the optical drive....that doesn't matter much really to me, lol.

Thanks guys, all the help means alot and if anyone has two cents to throw in, I'll be watching for it.

one of the highest PSU brands on the market mixed with an ungodly amount of watt ratings and only a single 12v rail




That is very funny. I don't mean get crazy with it here, lol. Thanks for making me laugh as I pushed the close button.

hey, just doing my job
July 9, 2009 2:05:41 PM

Since I already have your attention, how do you like your 4850 GPU? Do you get good FPS in games, and in what games?

BTW, does it run hot? I will be getting the ICEQ4 Turbo from HIS and it is rated as number one of running the coolest with great performance.

July 9, 2009 5:18:41 PM

ICEQ4's have great coolers, i only have problems with mine if i overclock more or run furmark. (but thats just personal temp preferances) as for FPS, i have a 1600x1200 screen and i get good FPS even on crysis on high. (still running xp) and i think thats more of a cpu bottleneck than anything else.
