PC Build Log #1- PSU Unboxing


Introduction: http://www.randelljohnphotography.com/self-build-p-c/

This is the first in a series of ‘Build log video’s’ I’ll be making.
They’re intended as more of a reference for my friend’s son Morgan, who I’m building the computer for, and shouldn’t be considered as a comprehensive guide to building a PC.  Saying that, if you’re thinking about building your own machine then you may find the videos useful.

I’ve ordered some of the components for the build, but not everything has arrived yet, although the Power Supply Unit (PSU), was delivered yesterday by courier.

This video gives some details on the PSU I’ll be using and the reasons why I chose it.

One of the main factors though was its cost, its power output and power management were obviously critical, but to purchase a ‘Corsair PSU’ of a similar power rating would have cost £30 more, whereas the Cool Master G550M was priced with at £51.66 inc VAT and delivery.
Bearing in mind my total spend on the build (not including OS) is just over £700, so I’ve had to think very carefully about component compatibility, performance and price, and try to balance everything to produce a very capable machine without breaking the bank.

Below you’ll find a screen shot of my power calculations which were checked using the calculator at http://www.extreme.outervision.com/psucalculatorlite.jsp . The figures actually show the maximum Wattage as 450W, but I’ve added a 90% (Thermal Design Power Redundancy Calculation) – TDP along with a calculation, that will take into account wear and tear of the computers components, so the figure of 450W is higher than my own original calculation of 375W draw from the PSU. It’s a good idea to double-check your calculation using this method, it can save damaging your hardware, and also ensure you’ve built some breathing room into your power supply considerations.

On line Power Calculator Adding calculations for TDP, and component wear and tear pushed my initial calculation up on Power Consumption up to 450W.

So I’m expecting delivery of the rest of the components next week (November 14), and I’ll post a few more unboxing video’s, and eventually move on to the actual build log video’s and final testing of the completed PC.
If you need some more info on choosing a new PSU for your build, have a look at this video from TechQuickie, it’ll fill in the blanks for you.

Hope you find this information useful, if you’ve got any question, please feel free to add them below and I’ll get back to you.
