New system build needs PSU - primary use is not gaming

Hola, :sol:

So I'm gutting my current mATX box and adding new in'erds; here are the specs.

Case - Silverstone Sugo SG01 h_flexibility/

Here are the new guts
Foxconn G9657MA-8KS2H

OCZ Platinum Revision 2 2GB 2P800R22GK

Intel Core 2 Quad Q6600 Quad-Core

Fo xconn 8600GTS-256 GeForce 8600GTS 256MB

T he additional gear:
3 fans (incl cpu)
2 SATA II 320gb drives
2 pci cards (extra USB and wireless)
dvd burner
variety of usb devices hooked up

I do mostly multimedia, video and some 3D work. I'm not much of a gamer except for a few here and there. I plan to OC to 2.66-3, depending on how much the mobo will allow, but nothing too crazy.

So how much power do I need? I'm guesstimating 400-450, but would like to get others opinions as well along w/ reco's on brands.

  1. Corsair 520HX would be perfect. $80 after rebate on
  2. HOLA -hehehe

    you could use it for gaming as well :)
  3. Use the PSU calculator. Observe the notes at the bottom of the page.

    That one should work fine, as long as the dimensions are correct. With the micro case i'm limited on space.

    I will, just not it's primary use :)

    I did use that, but dependent of settings i came up w/ 380-530 watts. The higher number was based on adding more ram, assuming the PS would die sooner, etc. The only part i'm not sure about is the Vcore for OC. I set the CPU speed to 2600 and Vcore to 1.5, but really have no idea what the Vcore should be.

    After that it came to 483w, so a 500w PSU should work, assuming the Vcore doesn't need to go much higher.

    thx for the help
  5. You don't want to be drawing 483/500=96.6%, that percentage is way to high even for a quality PS. Micro ATX case rules out the silencer 610.
  6. I also have a SFF micro ATX case (though not that one). I like the Mushkin 550200 550W PSU I am using because it is modular, minimizing the extra wires in the case. Check it out at:

    Note that it is a little deeper than a typical ATX PSU, but it does fit in my Apevia X-QPACK2 SFF case.
  7. Ok, after learning more about the vcore, i probably won't need more than 1.35 (if that) to OC the C2Q.

    System Type: Single Processor
    Motherboard: High End - Desktop
    CPU: Intel Core 2 Quad Q6600 2400 MHz
    Kentsfield Overclocked: 2600 MHz, 1.35 V
    CPU Utilization (TDP): 90% TDP
    RAM: 4 Sticks DDR2 SDRAM (only 2 initially)
    Video Card: NVIDIA GeForce 8600 GTS
    Video Type: Single Card
    SATA HDD: 2 HDDs

    DVD-RW/DVD+RW Drive: 1 Drive
    Additional PCI Card (avg): 2 Cards

    USB: 8 Devices
    Keyboard and mouse: Yes
    System Load: 100 %
    Capacitor Aging (+ W %): 25 %

    This gives me a power requirement of 450w. So now a 520 PSU should be sufficient - 86% used.
