What to look for in a PSU?:
This section is more of a general guide on what to look for when
selecting a Power Supply. Some of this may have been covered in a
previous section.
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.
Second, it should be at or above 80% efficiency at typical load. The
efficiency of this PSU is 80-83% @ under typical load.
Third, it should meet the latest ATX and other current standards,
environmental directives, over-voltage/under-voltage, and other
protections. This PSU meets all the current standards.
Forth, I’d recommend getting a PSU that has APFC. APFC or Active
Power Factor Correction is something that also 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. Thankfully, this PSU has APFC.
Finally, get a PSU that has enough leads for your setup.
