That's very interesting. How did you measure this amperage draw?

Here, I thought hard drives were a big draw. Running three IDE drives, the drives would power off and crash under disk load. One drive eventually died from the abuse. Running two IDE drives, I had occasional power cycling. I am now running one IDE drive and the system is stable.

I also know that a minimally loaded or overloaded supply voltage can cause difficult to locate system problems.


So, if I don't put ENOUGH draw on this "750W" psu, I will have problems? Great, then I should have gone with "500W" or "600W".

Match up the system requirements to the power supply capabilities (including future upgrades) and you will have a more robust system.

This was my intention, but I found it hard to find honest data about power usage. I couldn't find how much power the motherboard drew. And I wasn't sure how to trust the power supply manufacturer ratings. I've never seen (noticed) any mention of "efficiency".

Well, I've got a good source for buying PSUs. Maybe I'll have to review this even closer. Thanks for the tips.
