Hello everyone. I sought out this forum for specific purposes. I see this forum has a lot of electrical and electronics genious' and I thought I would turn to all of you for your advice.
I have been building stand alone computers (desktops) for years, for friends, family, businesses and my self. I frequent various forums and assist other people in building their own computers as well, help them troubleshoot problems, suggest mods and upgrades, or just building a computer from scratch - working up a list of parts, helping to sort out questions and make decisions. Through all of this, I have learned of needs that typical enthusiasts have that are not being addressed (to my knowledge) by commercial applications. As computing advances, the need for more power in personal computers is rising fast, especially for gamers who are building dual, triple, even quad video card gamer computers. Of course, each of these video cards consumes electricity, and in response to that need, various manufacturers have started to build 1 Kw and 1.2 Kw power supplies. However, these power supplies are very bulky and very expensive. A typical 1 Kw switching power supply, can cost $350. Since most enthusiasts have a rather tight budget, this makes it difficult to build a multi-video card (what is called, an SLI'd or Crossfire driven) gamer computer. Enthusiasts, of course, want to spend their money on the fastest processor, the most RAM they can stuff on a motherboard, and the most video cards they can afford. Power supplies, which as you know, are key to stability and longevity of the computer platform, is usually the LAST and most underconsidered
feature in any new computer build. The cost of a 650 Watt PSU can run as low as $70. So logically, the question has arisen, more often than you would think - Could we put two $70 psu's into a computer (for a total of $140 cost) and get a 1.3 Kw output rather then buy just one psu with a 1 Kw output which costs double that amount?
I would like to hear from any of you about how this might be achieved. Imagine having two psu's ganged together electrically, providing double the output for half the cost of a single higher output power supply. What would be a practical way of doing this? Would a single psu providing main power to the motherboard be interrupted by using a second power supply which is mainly used to feed video cards? Would there be a chance of burning out the components due to uncontrolled flux between the two power supplies? How could we put two of the exact same psu's together and make them work uniformly without causing variances, interruptions, etc. in the other components such as the microprocessor, RAM, motherboard, hard disks, ROM devices?
I would like to hear the concerns and suggestions of any of you who might have suggestions on what needs to be considered in ganging two psu's together to provide power to a single computer platform.
Thanks bunches for your help!
