Solved

Need suggestions for PSU, Sound card. Also need a component check.

I am going to be attempting my first system build and I'm in need for a few suggestions for a power supply, sound card and what sort of cooling I'll need for my computer. I'd also much appreciate it if someone could let me know if some of my components aren't compatible or if there are bottlenecks with any of the components I have chosen.

Below are my components, I've put the best price on what I've found for the components, if any knows of a website that sells at a better price it would be much appreciated if you were to share that with me.

Motherboard - DX58SO - $235

CPU - Intel Core i7-920 (planing to overcloak to about 3.4ghz) - $180

Hard drive - Western Digital 1.5 TB Caviar Black - $95

Graphics card - GeForce GTS 450 - $115

Memory - 8GB 2 X 4GB DDR3 1333MHz PC3 10600 DESKTOP RAM 1333 - $48

Disk drive - LiteOn iHOS104 4X Internal SATA Blu-ray Disc Drive - $109

Case - Cooler Master 690 II Advanced /140mm Blue LED Fan, 120mm & 140mm Fans - $58

Thanks in advance for helpful replies :D

    PSU
    With a GeForce GTS 450, you need a PSU with 400W and more power. 500W should do the job without being too near the limit.

    If you want to match your case and you don't want to upgrade your video card later :
    Cooler Master eXtreme Power Plus 500-Watt
    RS500-PCARD3-US

    If you planning to change hardware in 2-3years and keep your PSU, go with this :
    Cooler Master GX Series 650W 80+ Certified
    RS650-ACAAE3-US

    Cooling
    If you planning to overclock CPU, a lot of people recommand this heatsink/fan :
    Cooler Master Hyper 212 Plus
    RR-B10-212P-G1

    CPU
    According to Intel, you can't install 1333MHz memory with this CPU i7-920, only 800 or 1066MHz

    Sound Card
    With your motherboard, you already have something good,
    Quote:
    10-channel (7.1) Dolby Home Theater* Audio subsystem with five analog audio outputs and two S/PDIF digital audio outputs (coaxial and optical) using the Realtek* ALC889 audio codec
  2. Thanks for the great info.

    It seems it would be better for me to get a higher model of the i7 core. But of what I've read it states that all of the i7 cores are actually the same but with different default clock speeds. Can overcloacking allow me to install 1333MHz memory? Probably a stupid question, but it's always worth to ask.
  3. Yes you can use 1333MHz.

    Like this review, they use 1600MHz memory.

    Lots of forum/people tells to use DDR3-1600 over DDR3-1333 for overclocking with an CPU i7-920
