Power supply unit is a essential component when building a computer. When building a computer we have to look for many aspects but often we don’t put much stress on PSU position, today we’re here to help you with that.
Power supply unit = PSU = SMPS
Some PSU only have a back fan that work as exhaust. Other have a fan on the top to intake air and throws from rear. The question is how should you put PSU on your cabinet, the options are quite simple.
Front face – PSU fan on top.
Down face – PSU fan on down side.
When your cabinet has top power supply position with a separate chamber.
Cabinet situation – if power supply position is on top, and there is a vent on top of the cabinet case, put it upward facing so it can take air from outside.
On the other hand if there is no top vent on your cabinet, put it downward facing, the fan will get air from inside the cabinet and exhaust it from rear. It will also lead psu to work as a exhaust fan and decrease the temperature.
- No chamber + Top vents = Upward facing
- No chamber + No top vents = Downward facing
When your cabinet has bottom power supply position (with a separate chamber).
1. Chamber don’t have top vent – in this case the vent will be on the bottom side to put your PSU, down facing.
2. Chamber have top vent – put PSU upward facing.
3. Bottom position with no chamber, upward facing.
- Bottom chamber + Top vents = Upward facing.
- Bottom chamber + bottom vents = Downward facing.
- No chamber + No vents = Upward facing.
- No chamber + Bottom vents = Upward facing.
So this was a quick troubleshoot for people building a PC. If it help, do share it with your friends so they know the best way to put PSU. It is nice that you can use a Power supply to work as an additional exhaust fan to keep your system cool.
