sorry the gpu iam gettin is a msi 760. i got it the wrong way round lol

This motherboard doesn't support SLI, and even if it does, it's not recommended to put a card into x1 slot, due to highly limited bandwidth. Plus, having no empty space between the 2 cards will make them run really hot. So, in short words, you can only put 1 VGA on this mobo.

chezneyh · Jul 1, 2013

ok thanks worth a shot lol. damm

A B75 motherboard doesn't support SLI though it does support crossfire......So if you want to SLI be sure to get a Z77 mobo.

hi again friend. crossfire iam sure av heard of this, can you explain what this is, and is it worth it, i will be upgrading my power suply to dont know what watt am getting yet. thanks again

chezneyh :

Crossfire is a dual gpu technology used in the amd radeon cards. It is similar to the SLI. The main difference between the two is that SLI is mainly utilized by Nvidia GeForce cards whereas crossfire is utilized by amd radeon cards.

chezneyh · Jul 1, 2013

ok i googled it sounds good but some people say it depends what game you play and some gpu,s dont accept it. in my case if i got 2 760s will that work for me. and i will get bigger psu to

Madn3ss795 · Jul 1, 2013

Most motherboard with at least 2 pci-e slot shows that they support crossfire ( crossfire is AMD's SLI equivalent btw ), simply because it's free to put crossfire feature on their boards, while money had to be given to nVidia if a manufacturer want their board(s) to support SLI ( see how evil nVidia is? ). The fact is that, regardless SLI or Crossfire setup, if you want to run a dual vga setup on your motherboard without a huge lost in performance due to limited PCI-E slots bandwidth, your motherboard needs at least 2 PCI-E slots running at x8, and most B75 board only have their 2nd PCI-E slots running at X4 or lower ( including your b75ma-p45 ). Therefor, as said above, you won't want to run a dual vga setup on a B75 motherboard.

If you want to run 2 GTX760 in SLI, you'll need a new motherboard. And maybe a new PSU also.

And if everything is clear, don't forget to pick out the best answer :bounce:

ahh. ok so am out of luck then i just bought a msi 760. thanks man. if you think i can do it somehow plze msg me thanks again. awesome website for fast responce to

ayushde · Jul 1, 2013

chezneyh :

No, two 760s will not work in SLI in that motherboard. And yes you need to get atleast a 550W PSU if you are upgrading to a single 760

ok thanks i might just upgrade mobo in future thanks guys once again

Madn3ss795 · Jul 1, 2013

A cx430w can still hold a gtx760 in his system with a 4pin to 6pin power adapter used, but it's recommended to get a new PSU soon, of course.

chezneyh · Jul 1, 2013

Madn3ss795 :

could i just keep this psu. i would want to keep it only if it will feed gpu and wont overheat and brake with in a couple of weeks. it would save me money but will it last long term thanks

Madn3ss795 · Jul 1, 2013

It won't break within a couple of weeks, but most likely a couple of months, so you can keep on using it right now, but should prepare to get a better PSU at the same time, too. And if you're from the US then there's a nice deal on PSU right now, high quality 550w PSU for just 40$ : http://pcpartpicker.com/part/xfx-power-supply-p1550sxxb9

chezneyh · Jul 1, 2013

Madn3ss795 :

yea all just upgrade to a 600 watt. or will a 500 watt corsair be fine.

Madn3ss795 · Jul 1, 2013

The XFX 550w I mentioned is on par with Corsair's TX/HX series of PSUs, and is much better than CX series. You'll be find with a quality 500w or above PSU.

chezneyh · Jul 1, 2013

Madn3ss795 :

oh yea i forgot to mention i live in uk. so i cant get that deal :??:

Madn3ss795 · Jul 1, 2013

I see. The same PSU in the US costs £50. Things are so overpriced there. With limited budget you should just stick with the cx 430w then, and upgrade PSU after a month of two.

ayushde · Jul 1, 2013

Madn3ss795 :

But that could be risky and might ruin his gpu...

Madn3ss795 · Jul 1, 2013

Well it's the last solution, in case his budget is limited and he wants to use his new card asap.

ayushde · Jul 1, 2013

Yes I understand but it is much better to be patient than regret later...

chezneyh · Jul 1, 2013

thanks guys. i can get a psu. and i am now my friend wants to buy my 430 watt. so its all good. thanks for support you guys awesome.
