How big psu do i need

i also have read some bad reviews about this particular seasonic psu. Also Seasonic has cheap low budget series, which are less decent.

I would say those 2 EVGA´s that i have linked above seem to be decent, and have a good price point. Both single 12V rail units and fully modular. They also getting good reviews.

The EVGA G2 line is really good - rivaling Seasonic's highest end units.

Its based off Superflower's Leadex platform, which is an amazing performer.

Different wattage has different connectors.

Newegg page for the M12II 850w lists:

1 x 20 / 24P Main Power 1 x EPS12V / ATX12V (8P / 4P) 1 x EPS 12V (8P) 4 x PCI-E (6P / 8P) 8 x SATA 5 x Peripheral (4P) 2 X FDD (4P)

 

then ill pay a higher price for the EVGA 750W :P 

ill go with the evga 750w :P thanks for all the info ^-^

huh.. you're right o.o wow, can't believe they didn't show that on the video o.o well.. then i may just jump on it :P gonna look around at some reviews and such

nope alright the evga is about the same price, i'll go with that one.. i gotta stop changing my mind, i found the corsair hx750i on a small discount and thought "ooh maybe i should jump on it" then i realised that the evga is still cheaper and will work just fine xD

decided on the corsair rm 750w, since it's on 33% discount.. dang i'm lucky :P have found the mobo, gpu and ram and psu on sale now o.o i hope this keeps up hehe :P dang that's a good deal though.. well not i got myself a psu :) i hope 750w will be fine, i ran some random website check to see how much wattage i'd

need http://www.extreme.outervision.com/PSUEngine

and it said that the system will draw 483w with 2 gpus, but i don't really trust that website but.. i hope 750w will be enough :) thanks for all the posts guys and girls

Nice one! 33% off thats awesome. Good hunting.

It'll have more than enough juice to power sli 970's as they drain bugger all power. As seen here >> http://www.guru3d.com/articles_pages/geforce_gtx_970_sli_review,4.html

yeah that's an awesome price :P thanks :) can't wait to get my entire system!

well its basicly an easy calculation.

GTX970 strix is a single 8 pin card, which basicly means 150W from the psu, and max 75W from the pci-e slot, which means 225W max of the max. But the card will never use that, because there must be some kind of a safe margin. So the GTX970 strix will top arround ~180W 

But lets calculate in the worst case scenario:

  • 2x225W = 450W for both cards.
  • 200W for the rest of the system
  • Totaly 650W.

But in real life the numbers will be allot lower, because like i said, those cards will never top out the max power, because there must be some safe margin. So something like ~500W could be nearly accurate, because the system will not running full power all the time.

Realistic calculation:

  • 2x200W = 400W for both cards
  • 150W for the rest of the system
  • Totaly 550W

750W will be way enough. ☺

man am i happy to have posted on this forum with all of you experienced builders :P you've cleared up my mind and any doubts i had but now i know i made the right decision :) since i've never built a pc before i have no idea how to calculate anything like that :P 

can't wait to mod skyrim to hell >:3

this is some intense math stuff right here

indeed o.o
