Power Supply:
Next, select a quality brand name high wattage power supply. Going for a cheap
Power Supply is not smart. Remember, the power supply is responsible for keeping
your system running smoothly. There are a couple of important things to remember
when selecting a Power Supply. The first is wattage. Determine how much wattage
you are going to require by the amount of hardware you will be installing.
Generally speaking, a medium to high end gaming rig would require a 500-700W PSU.
If however, you are going hardcore and have a multiple video card setup with
lots of other hardware, select a PSU that’s above 700 watts. Also remember to
check the wattage on the +12V rail. In most cases a combined +12 rail is
preferred over multiple +12V rails. Second, it should be at or above 80%
efficiency at typical load. Third, it should meet the latest ATX and other
current standards, environmental directives, over-voltage/under-voltage, and
other protections. Forth, I’d recommend getting a PSU that has APFC. APFC or
Active Power Factor Correction assists the PSU in being more efficient and
therefore stable under load. APFC basically reduces total harmonics, corrects
input voltage, and it allows for a full input voltage range. Finally, get a PSU
that has enough leads for your setup. One other important thing to remember is
the number and type of leads it has.
I’d recommend any of the following:
