Psu recommendation

my new build :

I7-3770k

msi gtx680 lightning ed.

asus p8z77-v deluxe

kingston hyperx ssd 120gb x 2

16gb (2x8) ddr3 2133mhz g.skill ripjaws x

corsair h100 cooler

wd black 2tb faex

pioner sata bluray writer

corsair 550d case

I am thinking of getting an antec ew green 750 psu. I have checked a psu calculator and by its calculations a 750w should be fine. But I have seen similar builds with psu's over 1000 watts... Is there something I'm missing. Can anyone tell me whether 750w will be enough via their experience? Am a bit of a newb so any help would be appreciated.

Thanks

what do you plan on doing with the system. i see areas that you overspent on

1: you dont need a i7 3770k unless you are going to render many videos. a i5 3570k performs the same in games

2: a gtx670 peforms very close to a 680 in most situations. id get the msi power edition gtx670 or the asus directcu2 top gtx670

3: overspent on the motherboard. a gigabyte z77x-ud5h has nearly the same features for a hundred dollars less

4:id rather get a nice 256gb samsung 830 ssd instead. but 2x128gb at newegg is cheaper. pick the one you want

5; you dont need that much memory or that speed. just get regular gskill ares 1600mhz cl9 2x4gb for 44.99 at newegg. higher memory speed is useless

6: a noctua nh-d14 cools about as well but much much quieter. the fans on the h100 are hair dryers. adding aftermarket fans on it makes it cost over 120 dollars

7:i doubt you need 2tb of hard drive space but ok

8: i personally have the 550D and its pretty good but cabling can be a bit annoying. id suggest the fractal design define R4. its cheaper and is just as quiet. much more space in the back for cables

9; id get the xfx xxx 750w psu. i have one myself and it is very good and quiet

I am using the system for highend photoshop/corel painter as well as video editing/ music production and gaming, so I thought I'd get the best components.

So you think a 750w PSU will do the trick?

its more than enough

still, get the following from what i suggested

1: get regular cl9 1600mhz memory. gskill has some 2x8gb kits
2:the motherboard
3:the graphics card
4:the SSDs (much better choice)
5:cooler
6:case
7: psu

overspending doesnt mean you get better performance

WHY you would even Comment on his system is beyond me - ESPECIALLY since the OP is asking a question about a Power Supply!

@Patiala - your parts are fine for what you said you want to do, and yes a 750W PS will suffice, however, I'm biased and use Corsair. My only question to you is what do you plan on doing with the 2 SSD's?

It's fair to give advice in addition to what is asked, some people aren't as informed about things such as when an i7 is needed, or that a 670 is nearly the same performance as a 680, and a fair majority of builds are gaming builds; giving advice that may save someone 100$ is always a good idea. Advice is easy to ignore.

Here is a helpful link for picking PSUs http://www.eggxpert.com/forums/thread/323050.aspx (Anything in tier 2 and up is a good choice, Tier 3 is fine if you already own it, but I wouldn't buy one unless budget was very limited).
A good 750W is plenty (enough for SLI/xfire for most cards, but double check if you want to do this with a 680), 650W is even more than enough for a single card system.

Also be aware that configuring your SSDs in RAID will disable the TRIM feature, causing your performance to degrade over time; so going with a single larger SSD or only using the two drives as seperate drives is a better idea than RAID in the long run.

How can you possibly comment, and make changes, when you have No Idea what his intended use is...? :non:

i do this alot . if its games, get i5 3450 or i5 3570k with 8gb of ram. if it is video editing and work, get a i7 3770 or 3770k with 16gb of ram. thats what i generally assume and 80+% of the time, im about right

My recommendation is to spend a little more money and get the highest wattage QUALITY PSU you can afford. Call it an insurance policy. Using smaller PSUs is like running your car in first gear all the time. You can get away with it for a while but it will definitely fail prematurely. A PSU run at 50% of rated power will outlast a PSU running at 100% of rating. Power glitches are random and often intermittent and therefore undiagnosable. Spend the extra money and have a little more peace of mind. BTW, I am not in the PSU business.

I'm with the Big Troll on this one. Obviously, as his did, recommendations change based on additional information (such as intended uses for the machine).
A quality PSU can run at 90%+ 24/7 without issue; it's the junk units that can't.
Spatiala, do the programs you use benefit from GPU-accelerated processing? If so, check into whether Kepler is or is not your best choice; it's Compute capability is significantly reduced from Fermi. A GTX580 or HD7970 might be better Compute cards. If you might at some point want a pair of them, you will also then probably want an 850W PSU. Seasonic, Antec, Corsair, XFX, and Enermax/LEPA are among the brands to consider. For a single card, 750W gives you plenty of head room; 650W would actually be sufficient unless you're planning to add a stack of drives.

Just came across this top notch 850Watter do you plan to ever SLI ? If so get this now before it's to late the price will not stay this cheap for long

i generally dont like non-modular power supplies above 650w since there are a ton of cables that you will need to hilde.

You miss my point entirely. Any PSU can run at 90%+ for varying lengths of time depending upon quality. Those same supplies can run at 50% for much longer.

I agree but sometimes they are better option for somebody on a budget ;)

well if they are going to build a rig with nice video cards that require that much power, a modular power supply is the way to go

if they are on a budget, then why a 850w

I have a non-Modular PSU and it is not hard to tuck them away. Cable management is half the fun! :)

in the 550D, its a nightmare.cant put anything behind the motherboard tray since its recessed in and the side panel is about flush with the tray. the extra 8 pin CPU power (already had a 4+4pin) connector (that was my only harp about the xfx xxx 750w) was a pain to hide since the cables filled up the L shaped area that you can actually fit cables in

its basically a 500R with silencing but without the great airflow. i should have waited for the define R4 if id known that it would come out so soon.

because it's only 109.99 most 750W cost that or more ;)  but i agree modular power supply is the way to go but it's not a must.

Btw, that is with MIR. Never rely on MIRs for price reduction. You still have to pay the extra cost since it isn't an instant rebate. In that case, bigcyco's PSU is better to get.

Very looking forward to this machine!
