Eric Bowen Answers Our Questions: Part 2

We had so many questions in our original series about moving from the Mac to PC, that Eric and I chatted for nearly 90 minutes. Part 1 of this Insight covered the first 45 minutes of our conversation, this Insight covers the last 45 minutes. We are picking directly up, mid-conversation.

Your Questions Answered. In this Podcast…

  • How to you spec out a computer for on-set workflows that cover the full gamut of codecs, cameras and workflows?
  • New MacPro (trashcan) vs PCs for DIT setups
  • What is the biggest requirement for DITs when selecting a computer platform?
  • Custom building PC laptops for media professionals
  • Closed & Open Loop water cooling in professional PC workstation?
  • Why not just buy a gaming rig?
  • BIOS Settings: What impact do they have on post-production PC workstations?
  • How voltage settings optimize memory performance (and real time playback and render speeds)
  • How do you determine your battery backup needs?
    • Do you measure VA rating or Watts rating?
    • What is the difference between initialization load vs utilization load
    • The importance of providing 100% initialization load for your battery backup
    • Why you need 100% power initialization on boot and what happens if you under-power your battery backup?
    • What is Line Interactive Universal Power Supply vs Stand-by UPS?
    • Sine Wave vs Simulated Sine Wave: Which should you use?
  • How does an GPU Expansion Chassis magically provide full-bandwidth performance (or not)?
  • What should you put in a GPU Expansion Chassis?
  • Ryzan, DDR5, PCIe4: Quick thoughts about these emerging techologies

  1. The 1300W power supply example didn’t make sense to me. I’m an electrician become editor and the power supply shouldn’t draw 1300W unless it has a 1300W load on it. Are you saying the power supply does some form of artificial loading on initialisation and sticks in resistance to generate 1300W of required draw to test itself on startup? Seems weird to me? Devices will draw more on startup, especially motors which will draw heavily for the first couple of seconds as the magnetic fields attempt to get the device rotating, but that’s still then a calculation of the devices and their initial draw. Not sure you can make a blanket statement that a 1300W power supply will draw 1300W on startup just because you turned it on. Maybe there’s something I’m missing?

  2. Another couple of questions I have which I’d love to see answered in the next episode is:

    – graphics cards, blower versions where the exhaust is pushed out of the rear of your computer vs the other airflow versions where it’s put into your case. Is it simply a decision based on size of case?
    – graphics cards. Founders edition is OC by all the other manufacturers MSI, gigabyte etc and each adds it’s own flavour of cooling and clock speeds. Do you just get the biggest baddest OC for the best price va performance, or should there be some hesitation when buying higher OC cards?
    – OC in general, does it reduce the lifetime of the GPU or CPU? Or no harm done considering a max 5 year life cycle on CPU before upgrade to next edition.
    – In depth understand of RAM speeds and timings. CL ratings and when to go slower timings but higher frequency? What’s best for editing?
    – How much Ram?
    – 10GB/e performance anything bad to say?

    1. Yup. It makes the point that the Watts supported in many UPS’ is only 60% of the rated VA load. But on larger UPS’ the Watts and VA loads are identical.

      As I read that document, it’s the Watts load you should go by – not the VA load.

      Good find! Thanks for the link.
