Testing: For testing I will be putting the Coolmax USA LCD Power Supply Tester up against the internal voltage sensors on my Gigabyte GA-X48-DQ6 using Speed Fan a popular free to use benchmark/monitoring software, which monitors voltages and temperatures. I will be testing two power supply's for quality control. The PSU's used will be the Mushkin 800W PSU I currently use and the Collmax USA 950 PSU I will be reviewing shortly. For the sake of simplicity I will only be listing the +3.3v, +5v, +12v, voltages. Coolmax PSU:
|
| Test (in volts) | Coolmax USA LCD Power Supply Tester | Speed Fan |
| +3.3 | 3.3 | 3.31 |
| +5 | 5.1 | 5.16 |
| +12 | 12.1 | 3.39 |
We now see the draw back of using an internal sensor for your voltages. Speed fan is picking up the -3.3 volt as the +12v voltages. The internal sensors vary from motherboard to motherboard as well I have seen much stranger voltages from motherboards I have used in the past.
Mushkin PSU:
| Test (in volts) | Coolmax USA LCD Power Supply Tester | Speed Fan |
| +3.3 | 3.3 | 3.30 |
| +5 | 5 | 5.06 |
| +12 | 12 | 3.26 |
Again we see a weird variance between the 12v numbers. One thing worth noting is that the other voltages are very similar. I have also tested the Mushkin in the past with my multi-meter and the voltages are bang on with only hundredths of a volt differentiation between the two.
I tested two more power supply’s I had kicking around for de-soldering caps from, that I know where bad. Once I plugged them in and booted up the Coolmax USA LCD Power Supply Tester it beeped and displayed errors just like I hoped it would. The tester did very well in these tests, let's check out the final thoughts:
