Power Supplies

Power Supply Units, or PSUs, are among the most important components of a computer.

It's not the most famous item, though, with processors, memory, motherboards, graphic cards and hard drives/solid state drives fighting for the spotlight...

Anyway, here are a couple of links that validate both my experience, observation, and yes -- blunders, too.
Titles should be self-explanatory.

• PC Power Consumption: How Many Watts Do We Need?
• The Big Power Supply Guide - Brands
• Gold and Bronze: Seasonic Power Supply Units Roundup
• Plus these couple of forum threads that show a good discussion on both PSU brands in general and specific models of PSUs.

Hope you find these links useful!

Disable hibernation in Windows 7

http://www.sevenforums.com/tutorials/819-hibernate-enable-disable.html

Great tutorial, short and sweet. Why would you want to disable hibernation? To save hard disk space. If your computer has 4 Gb of RAM, the system will create a 4 Gb file in order to be able to hibernate.

Therefore, you'd want to disable hibernation especially if you have a desktop computer and/or don't need to use the hibernation feature, which is mainly aimed at laptops.

In a nutshell, you just need to run the command prompt as administrator(AKA elevated command prompt, see screenshot at the end of this post) and type

powercfg -h off

and then press Enter. That's all, folks!

Right-click on the Command Prompt icon and left-click on "Run as administrator"
