Will These Computer Parts Be Compatible?

Building a computer for the first time (please excuse my incompetence) for gaming, and I need to know if these parts are compatible with each other before I purchase the rest of my parts (Already bought the case, PSU, RAM, and HDD). Here are my specs:

CPU: i5-3570K
PSU: Coolmax ZX-500 Certified 80+ 500w
>>> http://www.newegg.com/Product/Product.as…
RAM: Ribjaws 2x240 pins 1600 DDR3 8GB
>>> http://www.newegg.com/Product/Product.as…
Case: Antec Three Hundred Mid-Tower
>>> http://www.newegg.com/Product/Product.as…
HDD: Seagate Barracuda 2TB 7200RPM
>>> http://www.newegg.com/Product/Product.as…
Mobo: ASrock Z75 ATX
>>> http://www.newegg.com/Product/Product.as…
OS: Windows 7 Home Premium
GPU: Sapphire Radeon HD 7870 GHz Edition 2GB
>>> http://www.newegg.com/Product/Product.as…
Wi-Fi Network: Random 300Mbps PCI card

The computer will mainly be for gaming and basic computing (Microsoft Word, surfing the web). I am mainly concerned with the fact that the 7870 needs 2X75 6 pins, and my PSU has one 6 pin and one 6+2 pin - Will I need the pins for anything else besides the GPU? I am not planning to ever overclock (Buying the i5-3570K because it's on sale right now and cheaper than the others) but do plan on upgrading my PSU and Crossfiring my 7870's when I deem that it is starting to lag for games.

  1. first of all dont take that ps its very horrible and might fail the rest of ur system.

    so ill recommand this instead, even if not overclocking never get coolmax powersupplies theyre seen as some of the worst of the low-end.

    LEPA G Series G850-MAS 850W 150$ and very nice for the price


    enjoy, the rest of the system is solid except the powersupply witch u now have a better choice :)
  2. None of you links work.

    Anyway, I won't personally recommend nor buy that PSU. Coolmax doesn't have the best reputation(if it has any at all), and a cheap PSU might end up frying your components if ever it fails.

    That board does not correctly support SLI/Crossfire, get the Extreme3 or 4.
  3. Assuming price is a concern, hence why you went with a 30 dollar PSU, I would just grab this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371051

    Would grab it now instead of a 50 dollar one now and a 100 dollar one later. And no, that coolmax psu is garbage, I wouldn't use it to power a toaster. The one I linked is easily more than enough for 2x 7870s and an i5.
  4. that works also, but if he can afford it, gold rated is more energy friendly imo, and 100 watts more does come in handy.


    quite solid :)
  5. those are all good choices also
