Question 1

Is the CPU power connector a 4 pin, 4+4 pin, or an 8 pin connector? It doesn't really specify and judging by the pictures it is a 4 pin, but I just want to be sure.

Accepted Answer

The CPU connected on this PSU is a 4 pin connector, please note that most motherboards with 8 pins can be powered by a 4 pin, but always double check with the manufacture of the board and CPU to make sure.

Question 2

Does this have a 6pin connector?

Accepted Answer

6 pin power connector for pci express graphic card x 1
right from the side of the box, hope this helps.

Question 3

Is this compatible with a intel core i3 processor?

Accepted Answer

This should work in most PCs including those with i3 CPUs. However, these are about an inch longer than standard power supplies since they have 2 fans - one in front and one in back. I find they fit snuggly in some PCs and comfortably in most. On a rare occasion, they are too big. So measure your case first and see if it will fit.

Question 4

I just upgraded my video card and it needs 400 watt power supply. Will This unit be a good fit with my older system?

Accepted Answer

Based on the specs I see here and on the web assuming you didn't upgrade much and you are using an older CPU as well this should be more than enough. I got this for my older system with a Socket 939. If you upgrade your graphics card is really the only time you will need to upgrade it higher than 400.

Question 6
