Almost any power supply with a 12 VDC output can be used with a distribution board in a PC.
Having said that, I should probably also mention some of the reasons why using PSU's designed and optimized for PC's is better for component stability and longevity:
- Guaranteed maximum ripple and noise rating, which per ATX specification should not exceed 120mVp-p (peak-to-peak). This value measured in the best currently produced power supplies can be lower than 10 mV, which makes it an order of magnitude better at suppressing voltage spikes (oscillations if you prefer) than the specification requires:
- Hold-up time at full load, which, again, per ATX (intel) specification should be no lower than 17ms: From Tom's Hardware: "Hold-up time is the amount of time that the system can continue to run without shutting down or rebooting during a power interruption". Good PSU's can almost double the value during a full load:
These categories are just to get you started as each has many subcategories that a good PSU reviewer must test in order to know how a unit performs.
If you look at the specification for the MeanWell LRS 150 series, you can see that the guaranteed ripple & noise value (for the 12v model) is higher than what it should be: 150mVp-p vs 120 mVp-p. This suggests that the PSU should not be used for desktop PC's.
However, if you look at the actual test report from a production unit, you can see that the measured value with the particular power supply was well within specification at 28mVp-p.
Holdup time is amazing at 60Hz (i.e. in the US) at 35+ms and under the specification requirement at 50Hz (i.e. in India) at 12+ms depending on the AC voltage.
I hope that you are now a step closer to making an educated decision on whether you should use the PSU in your particular workload and reliability requirement.
