I am getting a new PSU soon to replace the current 330W Enermax (EG351P-VE, how misleading is the model name!), it just isn't good enough for overclocking my nForce2 system.
I was looking at the SPI/Sparkle/Fortron (whatever you call it) PSU and saw that they have several categories, namely ATX12V, ATX 2.03 and Active PFC.
I know that ATX12V is equivalent to ATX 2.03 rev1.2 and is the latest standard, according to this site: http://www.formfactors.org/
1) What is PFC? And what's the difference between the Active and Passive types?
2) Which rail (+3.3V, +5V or +12V) is the CPU on? I'm running a TBred B 1700+. What about the P4 systems?
3) How important is the +3.3V and +5V combined power?
4) Anyone using Aopen PSU here? I see that they have the same model names as the SPI units, wonder if they are the SPI clones.
5) Anyone know if current PSU (ATX12V/ATX2.03) will work with Athlon 64? Don't want to invest in an expensive PSU and later find out it need to be replaced when I upgrade in one or two year's time.
Thanks in advance.
