Can my power supply handle these specs?

[squilly827]

I'm looking to build a computer from the ground up, its a 750w Corsair TX750, these are my main specs:
PNY GeForce GTX 580 Overclocked
Intel Core i7 2600k 3.4 GHz
Gigabyte Z68 (http://www.amazon.com/gp/product/B00518M74I/ref=ox_sc_act_title_2?ie=UTF8&m=ATVPDKIKX0DER)
1 TB Western Digital Hard Drive
LG Disk Drive
8gb RAM (2 sticks)
I'm pretty sure thats it....my main question: Can my power supply handle it? Thanks in advance!

Yes of course!
You're fine.

Really? Others are saying I should go with an 850w...like here: http://www.techsupportforum.com/forums/f210/can-my-power-supply-handle-these-specs-608531.html#post3487727 and http://www.hackforums.net/showthread.php?tid=1858260 . Just a little conflicted.....

Core i7 965 / X58 based @ 3.75 GHz = requires more power then an 1155 platform with a 95W cpu
Under 450W full system load

Thats without graphics card though, I'm pretty sure my graphics card runs at about 220-240w

No it's not it's full system load = everything including the gpu.
The whole purpose of the page i linked.
More power consumption test = full system power includes cpu/mobo/card etc

Doesn't seem right....450w with those specs.

You can google to your hearts content i've yet to read a review with full system power consumption over 450W.

Hmmmm its weird. Everywhere else I seem to look says it should be 600w - at least. Even PNY's site.

Well a Corsair 750 is enough and the maker usually has a minimum recommended psu size based on substandard psu's = covers their a$$

A lot of power sources deliver the most efficiency and last the longest at 50% of capacity so if you NEED 450 the power source that might deliver it to you most efficiency could be a 900w.

It really depends on the PSU in question. A 450 that would deliver 450 at 100% of capacity would probably work fine, but it may burn out quicker as well.

Look at the charts for the device if you can to see about optimal efficiency before you buy it.

If you are getting a 450, it should probably be about the most expensive one available.

He already has a 750W Corsair btw !
Would you not agree that's fine?

I wouldnt trust anything they suggest in The hackforums. Getsompie knows jack about hardware.
Your psu is fine

Only 600w needed

If you want to objectively, accurately and scientifically determine what PSU power is required for your Vid card and PC in both watts and 12v rail amps., the forum Utility link below will show you how easy it is to calculate this information and objectively determine which PSUs are quality built, reliable PSUs that can meet your needs. Be advised that the available 12v rail amps. is just as important as the total PSU wattage. You need both to be correct.

That psu got more than enough for both MOOOOOOOOOOOOOOOOOOre than enough

 

[squilly827]

Okay, how about for two 6950's? That idea just came up, and its the same price.

Yes the Corsair 750W will handle that no problem.

Reason why i bought a Corsair 750W 2yrs ago,it's a good size unit that offers flexibility.

 

[squilly827]

Okay thanks. I'll really look into the two 6950s. Just gotta get a motherboard with two PCIe ports/slots. Any suggestions? How much better are the two 6950s compared to the 580?
