Does My PSU Have Enough Wattage For My Build?

Hi. So I built my first system fot fun a few weeks ago but after trying to overclock my AMD FX 8350 cpu using the software the MSI Mobo came with I ended up frying the mobo and probably everything else since I saw smoke come from mobo and then I got a black screen and even trying to switch everything out still nothing. So I RMA'd almost everything from Newegg and ordered new hardware. So this time I'll be much more carefull. But this time I decided to upgrade a few things so I need to know if I did indeed buy a PSU with enough Wattage for my build.
Please let me know if I have enough wattage but only if you yourself are experienced in PC'S and know exactly what you are talking about!
You can comment on my build too but please if you have nothing intelligentnto say then don't say it all.
Thank you all ahead of time.

Anyways, that's my build. I know there is a lot of things included, but I wanted something that I can use for games and multi-tasking, watching movies and downloading and listening to movies, etc. So I hope some of you pc experts can check out my build and tell me if my system has enough wattage with the 1300W.

Thank you.

More about does wattage build
  1. I would change literally every component of that build.
    I would get an asrock z77 extreme4
    The an i5 3570k
    get a 7950, which is stronger and can overclock past the 670.
    Get 16gb ram, MAX, I would recommend 8 though.
    Why do you have 2 fan controllers, and what is the point of a ram cooler? When I worry about something overheating, it isn't ram. 1300w is way overkill, get 750-800w.
  2. Thanks bro. I appreciate your insite but I prefer AMD over Inel, personal preference so I wilp stick with the AMD FX 8350. Since I already have the 4x8GB DDR3 1600 I will stick with 32GB. Plus I've noticed that previously when I only had 8GB and I would be doing a lot of things at once my system would lag big time because it showed me using like 80-90percent of my ram. Now when I just built the first build before I screwed everything up overclocking and had to RMA, I had 24GB ram and I noticed it got super hot so thats why I decided to get the ram fans. Now I got 2 different touch fan controllers because my built has a lot of fans, the case has like one top, one rear, two front, one side, and one center, the cpu water cooling fan, ram fan, the hdd cage fan, ssd fan. So that is a lot more fans than the Aerocool Touch2100 can manage since it only manages five. But if I add the NZXT to it which manages four fans I believe, then I get to control all my fans and I can turn on and off anf change rpm of each fan thus not wasting power when I am not doing anything that will really heat up my system. And as for the 1300w being overkill. And you said all I need is like half of that. The description on my EVGA NIVIDIA GEFORCE 660 GPU says it requires a minimum 450w and since I have 2 of them in SLI set-up then doesn't that mean it will need at least 900w, plus the AMD FX 8350 says it needs atleast 145w so just that alone equals 1045w, and then the mobo, bluray drive, dvd drive, 3 hdd, ssd, all the fans, the 4x8GB rams, 2 touch screen fan controllers. So I am afraid that all that extra will be way moretan 275w and thus 1300w won't be enough. That's why I made this post so that I can get insight on whether 1300w psu is enough or not!
  3. The 450 recommendation is for a FULL SYSTEM + GPU. So 1300 watts is an insane amount of power.

    The FTW edition of the card is rated at 140-150(the overclock may add 20-30 watts or so if you ran furmarks) watts per card I believe.

    To give you an example.

    A i7 2600k @ 4.4 with a 5870 card a hard drive and 3 ssd's idles at about 80-90 watts. At load, I have yet to see it get much over 350 watts(250 is most games).

    now AMD recommends 500 watts for a single card and 600 for 2 of them.

    I would not be surprised if half that power would work with a quality power supply.
  4. Well, if you truly feel you need all those fans, I can't convince you, but overclocking ram does almost nothing. If possible get a 7950. When they said you need 450w, that means the entire system, the cards won't even get to 170w use. What is this build for? I would still recoemend intel over amd at this point, even though amd is getting better and you can't really go wrong either way. How many apps are you running at once to be using 8gb ram. I have 6gb (long story) and I haven't even gotten close to maxing out that, I would recommend getting rid of at least half of that. Also, I don't see why you get a cooler for your storage devices.
  5. a 850 watt PSU will cover that!

    using 660 SLI doesn't mean that each uses 450 watts for itself but for the whole system; cpu, hard drives, RAM ect. the card itself is about ~120 watts.

    here, lets go with some basics:

    that "typical system" had 2 4GB sticks of RAM and an SSD ( i am not going to include the GTX 680 since for that benchmark, it wasn't really in play).

    so you have 218 watts full load. overclocking the 8350 can ad up to 90 additional watts. (excuse me for not finding that benchmark ATM) so now your talking 310 watts (i like rounding up) and 240 watts for the 660 SLI. for 560 watts

    add 5 watts for each hard drive (10 watts) and another 5 watts for each fan ( i lost count after 9 so i'll say 45 watts). 4 watts for each stick of RAM ( 16 watts).

    so where are we? 631 watts? and the idle will be much less than that; possible 200 watts if you use the fan controller. you do not want a PSU that is more than 20% load when you idle; the efficiency takes a big nosediver and you'll end up wasting the money spent on a 80+, bronze, silver or gold PSU.

    so an 850 watt PSU for a 200 watt idle (above 20%) and 631 watts on load ( under 80%) is perfect.
  6. 1300 Watts is a little overkill, but I have a question on your choice of graphics card, if you're planning to run SLI you should just grab two identical cards, because SLI will cause your 660 TI to scale back to the speed of a regular 660.

    Power supply wise, 850watt will be more than enough on a quality power supply.
  7. Wow thanks guys for all the quick responses. I am learning a lot. Now here are a few questions I am have from what has been said. Now I do have a Apevia 1000w psu which I had from first build attempt before I decided to I upgrade from 1 560gpu to 2 660 and all tje extra fans and fan controllers... Would that be better? Lets for example say I am lazy and dont want to rma and exchange my psu. What will happen if I run a 1300w psu when all I need is like 850w like you say? Will it kill my system or it will jusy make my electrical bill a tad bit more?

    Now a question for the guy who told me that if I do SLI I should get two identical GPUs. Well the GPUs I got are both same except for one runs more Cudo Core than the other. Everything else is same both are GDDR5 3GB 192bits, so will it still make difference if the Cudo Cores differ by a few hundred?
  8. The cooler for storage was cheap so I figured why not an extra fan won't hurt especially if my hdd will get hot when im downloading a lot of music... I mean they make them for a reason right? If the hdds didn't overheat then they wouldn't make hdd fans. Plus it allows me to put everything in the 5.25 bay...

    My system is for everything. Not much of a gamer but I did receive a few free games like Assassins Creed 3 for free for buying the gpu so maybe ill start to play. I also download lots of music. Most of the music I listen to has hour to two hour long tracks so lots of long downloading and then buring into cds. Movies too. Also I play and study lots of chess, trying to be master so I do a lot of thongs there whicu require multi tasking from different softwares. And some of the chess programs I use like Deep Fritz 13, Chessmaster 10, and Deep Ryba 4.0 performs better analysis if the system has more ram and fast processor. So yea. But other than that just wanted to build a nice system and learn the process...
  9. It'll just cost your more in general Genkstar, like we said, a quality lower wattage PSU will serve your needs. I'm not a big fan of Kingwin PSU, so I'd watch out for the quality.

    Yes, it does make a difference. They will scale back your higher performing GTX 660ti to the speed of a 660, which just means you're wasting roughly 100 dollars on the TI version of the card.
