when it comes to the power aspects of computers, im pretty much retarded. im looking at getting a low end I7 intel chip, an ati hd 5850 video card. the MB will be running a triple channel memory setup. i have 2 sata drives that will be in the system with 2 dvd burners and eventually a SS drive. the power supply im interested in is http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4256918&sku=K450-2507.
im worried that it isnt going to run continuous power/enough power for the video card with the cpu through each rail.
any info would be great...thx
 
That sir is overkill. It will work fine. So you have an example, I run an i5 quadcore with 4 gigs of triple channel ram a Nvidia 465 card, 2 DVD burners, and 8 fans. My power supply is 700MHZ. With my same power supply im still in the range to run 2 Nvidia 465 cards in SLI according to Tom's.

To answer your question, I think your more than fine with that 800 MHZ lol.
 
i just dont want to run the risk of it being borderline and have it mess something up. plus, if i ever do add components, ill have some leeway. the wattage really isnt my concern. but i just dont know about the rail amps. i would think that they put specs in there for a reason. question is, does the power supply have enough power per rail to go to the video
 
I also use a 5850, i7 930, 2TB 7200 RPM HDD, 40GB SSD, 6GB DDR3, DVD-RW, and I'm using a 950w supply, but that is because I plan on adding another 5850. So by using the asus calculator I posted above (I guessed at USB ports and fans) the minimum for you would be a 600W. However, that'd be running at 100% if you just got a 600. The sweet spot for a power supply is %60-%80. So you'll want a little over. I'd say that 800W one will do you good. Gives you a little room for improvement as well.

Edit: Actually I noticed that that is a modular power supply. That means you'll have to go out and buy the power cables individually. I don't know if you realized that or not.

Huh? Since when?
As far as I can see all cables he'd need are included in the box.
Including 2 cables with 2 PCIe VGA power connectors on each supporting even the high end SLi and Crossfire setups without needing any extra adaptors or splitter cables.
Which, for now, as far as I see he isn't.
Still, if he wants to in the future, he can.

Unless he's eventually building a system with more then 6 internal hard drives that need a SATA power connector I think he'll have what he needs.

@MO:
Looks like a solid PSU there, I have a similar build regarding power consumption and am doing fine with a 700W which has supported my Crossfire build before I went back to a single GPU build.
As Takumi already sais, for now that thing is overkill, but will leave plenty of room to expand in the future.

My own build:

Asus M4A89GTD PRO/USB3
AMD Phenom II X4 945
OCZ DDR3 PC3-12800 Platinum 6 GB 7-7-7-24
Nvidia GTX 470
Intel X25-V 40GB SSD Hard drive
WD 160 GB Hard drive for apps. (My storage is kept on a seperate file server)
Generic DVD-Writer

as an update, i finally made a decision on PS. i ended up going with a corsair 750watt. after all instant and mail in rebates, price comes to 90bucks or so. i made a decision to not go with the modular. as much as i really wanted the modular and "the cool lights", i figured, unless im going to be staring at the inside of my case instead of actually using the computer, the modular and cool effects wont matter.
 
Cool effects yeah, I can get into that.

But the reason for me to go modular is cable management.
A modular PSU saves me a lot of time and irritation of having to bind cables and keep them away from my fans and airflow.
The cables I don't need simply aren't there so can't be in the way.
And the fact that I'm not staring into a jungle of unused cables when I open my PC for cleaning.
It makes it a lot easier to get to the components I need to get to.
For that alone I'm willing to pay that extra cash for a modular supply.
 
Just got the parts today. Gonna b forced to do some immediate upgrades that I didn't expect....the video card is massive. My pc doesn't have enougvh room in the case for the card...not only that, but the PS has a lot more cables than I expected. I should have gone with modular ! Oh well, ill just have to spend extra time hiding cables
 
Yeah, it's performing excellent, and it's really quiet compared to my last PSU, even on real heavy load.

Sweet, I guess I'll give CoolerMaster a chance on a couple of PCs eventually. I need an alternative to SeaSonic and Silverstone to propose to my customers and I started to look at some of the PSU CoolerMaster got in their line-up. Thanks for the heads up :).
