Gaming pc - Compatibility Check

So i'm building my first gaming desktop. My budget is around 800€, and i'll be ordering either this week or in the beginning of September. I've already had previous advice and i've also done some research on computer hardware. This is my current build:

CPU Intel Core i5 3570 - 3,4 GHz - LGA1155 215€
Motherboard ASUS P8H77-V LE - Socket 1155 - Chipset H77 - ATX 100€
RAM GEIL Memory PC Black Dragon 2 x 4 GB DDR3-1600 PC3-12800 42 €
Graphics SAPPHIRE TECHNOLOGY Radeon HD 7870 GHz Edition 269€
Hard Drive Seagate HDD Barracuda 3,5" - 500 GB 65 €
Case Antec PC Case Three Hundred Black 55 €
Power Antec HCG 520-EC 520 W 60 €

TOTAL: 806€

So what i'm looking for is a bit of feedback in regards to compatibility between the parts, as well as whether or not the PSU has enough power for this system. Thanks in advance!

  1. It is a nice build, but you will need at least 500W to power a Radeon HD 7870. PSU brand is also very important. Get yourself a Corsair PSU.

    Corsair Builder Series CX500 V2 500W

    You also can save some money on memory by getting a better brand.

    2x Corsair Memory Vengeance Black 4GB DDR3 1600 MHz
  2. One thing i forgot to mention is that i live in Portugal, and this is the site i'll be ordering from:

    Anyway about the PSU, the one i posted is an Antec 520W PSU. I had initially looked into that CX500, but i was advised to get the antec one instead.

    About the RAM, yeah i'm not sure about Geil, as i've never heard about them before making this build. However those black dragons are the cheapest on the pixmania site with my desired specifications (8gb, 1600mhz, 1.5v)
  3. Antec is not better than Corsair, but that is your decision. There is a good deal with a 600W PSU:

    Corsair Builder Series CX600 V2 - 600 W

    You still can get the 500W PSU for a bit less

    Corsair Memória PC Vengeance Performance 2 x 4 GB DDR3-1600
  4. Well yeah, i do like both antec and corsair products. The GS500 does look good. I'll probably think about it a bit more and decide when i actually order, but i'm not very worried about that since i'm sure both the GS500 and the HCG 520 are quality products. My main question was whether ~500W would be enough for the system, but you've already cleared that.

    Will probably replace the memory with that vengeance one you linked though. Considering the big discount it's at, 8€ are worth the brand imo.

    Either way, thanks a lot for the help!
  5. You are very welcome!

    So hello again, i've been thinking and i made some upgrades to my build. I decided that it would be worth it to invest a little more and unlock the possibility of overclocking in the future. So here is the new build:

    CPU ------------ Intel Core i5 3570k - 3,4 GHz - LGA1155 -- 230€
    Motherboard ---- ASROCK Z77 PRO3 - Socket 1155 - Chipset Z77 - ATX -- 99 €
    RAM ------------ Corsair Memória PC Vengeance Performance 2 x 4 GB DDR3-1600 -- 50 €
    Graphics -------- SAPPHIRE TECHNOLOGY Radeon HD 7870 GHz Edition -- 269€
    Hard Drive ------ Seagate Disco rígido interno Barracuda 3,5" - 500 GB -- 65 €
    Case ----------- Antec PC Case Three Hundred Black -- 55 €
    Power ---------- Antec HCG 520-EC 520 W -- 60 €

    TOTAL: 828€

    I'll have to stretch the budget a bit, but that's ok. So my new question is whether or not the Asrock Z77 pro3 is a decent motherboard for overclocking. Nothing too extreme, of course. If not can you suggest something better around the same price range? (again, i'm buying from, which is a portuguese site, but you shouldn't have a problem using the search function).
    I'm also aware i'll probably need a better CPU cooler, but i'll look into that later as i won't be overclocking right away.
  7. For a little less you could get ASRock Z77 Pro4, which is a bit better for overclock.

    ASRock Z77 Pro4 LGA 1155

    You will need an after market CPU cooler for OC

    For a moderate OC get Cooler Master Hyper 212 EVO

    For more serious OC get Noctua NH-D14 Dual Radiator
  8. For a little more you mean. The link you sent is in pounds :p
    Anyway yeah, i was also considering the Pro4, which is 112€ in pixmania (

    If it's worth the extra 13€ for overclocking purposes, then yeah, i'll go for it. If the Pro4 only gives you those extra slots/ports, then i'll probably save 13€ and go for the Pro3.

    About the coolers, thanks for the tips. I don't really know anything about coolers but those seem nice from other recommendations i've seen. Either way i won't be buying it with the pc, but i'll definitely pick one up later down the road when i decide to overclock.
  9. Ah sorry for the broken link. Apparently those don't work with the quick reply function and it won't let me edit my post.
  10. ops sorry about confusion between pounds x euro.

    IMHO the ASRock Z77 Pro4 worths the extra 13€
  11. Ahah it's alright.

    Anyway I'll look deeper into them to see if i have any use for the extras in the Pro4 before deciding.

    And well, hopefully that will be the last thing i change in this build before making the purchase. After so many hours spent searching for the hardware that best suits my needs/budget, i'm definitely much more confident about my choices, this being my first build and all.

    And again, thanks for your input!
