Want to buy a graphics card. Is my current PSU and Motherboard ok.

Hello. I want to upgrade some components in my computer to start playing a few games like Euro Truck Simulator 2 and The Walking Dead. Here are my current specs taken from speccy.

Windows 8.1 Pro 64bit
PSU 300w
SSD OCZ Agility 3
Intel Core i7 2600 @ 3.40GHz
4.00GB Single-Channel DDR3 @ 665MHz (9-9-9-24)
Motherboard - Pegatron Corporation 2AB6 (CPU 1) this one
Intel HD Graphics

The graphics cards I was looking at purely based on my budget of up to £100 are Asus HD 7770 2GB AMD Radeon or Asus Nvidia GeForce GTX 650 Graphics Card (2GB GDDR5). I think I'll need a better PSU so would this be good enough? Corsair Builder Series CX 500 Watt ATX/EPS 80 PLUS Bronze

Open to suggestions on different parts and brands. Thanks

  1. of course you should go with 7770 but also buy a new psu, dont put any graphics card on such a low psu...a cx 450 will be also fine for a 7770 or even a gtx 660!.
  2. Yes CX500 is good but its a budget PSU, so its not the best. You can choose either GPU, both are almost same in performance. And yes your MB will support both GPU's.
  3. Should the 7770 fit on the motherboard ok because at the back of the pci slot its really closed to the memory slots. With the 7770 and my other specs would I be able to play Euro Truck Simulator 2 and The Walking Dead and other games ok? I'll prob upgrade the ram to 8gb at the later date. Regarding the PSU being a budget one. Would that noticebly effect the performance of my computer even though it's 500w?

    Is there anything better that the 7770 and the PSU at a similar price or should I go with those two? Thanks
  4. Yes fitting of the card is a real issue! This is the Card Dimensions 8.3 " x 4.4 " x 1.4 " you are going to buy, so I would suggest you to cut a cardboard of the size of card, then place it inside the case, see if it fits or will collide with something.

    Yes you can play fine your desired games, nothing to worry to worry about that.

    Yes upgrading to 8GB of RAM is a better idea.

    No the wattage of PSU will not affect the gameplay.

    Yes you can go with 7790 the price is pretty similar. Or with few extra bucks you can go with HD 7850. And you can go with this PSU also.

  5. Thanks I think I'll go with this Asus AMD Radeon 7790 2GB PCI-Express HDMI DirectCU II OC. I think my case will struggle to fit all the cables from the power supply so was looking at this modular Corsair 600 Watt Builder Series CX 600 Modular which also comes in 500w Corsair 500 Watt Builder Series CX 500 Modular. What do you think about those? They have 2 x 8 pin PCI Express power with detachable 2 pin section. Would that fit the graphics card?

    Also a bit more info about [url=http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay/?sp4ts.oid=5080737&spf_p.tpst=kbDocDisplay&spf_p.prp_kbDocDisplay=wsrp-navigationalState%3DdocId%253Demr_na-c02889484-22%257CdocLocale%253D%257CcalledBy%253D&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetokenmy computer the motherboard is a micro atx would that be a problem? It says the case is ATX so I assume the PSU will fit?

  6. The GPU only needs one 6 pin power connector from PSU, so that is not a problem, you will be fine with either PSU. I think 500W Modular will do fine, no need for 600W. And the PSU will fit in the Case, as the Case is ATX standard. CX series are budget series, so not the best but it will serve the purpose.

    My only concern is if the GPU will fit in your Case or not. Case Dimension Height:15.28" •Width: 6.89" •Length: 16.14".
    And the GPU Dimensions: 8.5 " x 5.1 " x 1.5 ". So the GPU may fit tightly, but I think RAM will block the way of GPU.

    So as I said earlier cut a cardboard of the same size of GPU, and place it inside the case with RAM and all the components in place, look if anything collide/block the way of GPU.

    So the conclusion : the PSU will fit with no problem, but I doubt about the GPU, so make the calculation first, before you buy anything. Good luck.
  7. Hi, I cut out some cardboard to 10.47" x 4.25" x 1.54" which are the dimesions of the Asus Radeon HD 7870 GHz Edition 2GB 256-bit GDDR5 because I've been looking at that also which is a bit longer Asus HD 7770. The mobo length is 9.6" So the 7870 is longer than the mobo and both the 7870 and 7770 would hover just above the blue sata port which I think is ok.

    The back of both the 7870 and 7770 are flat which will just miss the ram slots judging from my cardboard. Having looking at other micro atx mobos like the ASRock H77 Pro4-M Motherboard the PCIe and the ram slots look to be the same position as my mobo so do people usually just use a ATX mobo instead for these big GPUs? My case isn't big enough for an ATX mobo though.

    Assuming the GPU fits ok then I'd look into getting a better mobo, more ram and a bigger case because with my current setup I wouldn't be able to take full advantage of a GPU plus it'd be a tight fit.

    Thanks for your help.
  8. Yes that is the right decision. Good luck.
