Since we don’t currently have access to an ATE load tester, a multi-meter is used to show each of the power supplies performance on the 3.3v, 5v and 12v rails.  Although we can’t do full load tests, we can provide relative information regarding variance and fluctuation of current and ripple on the rails which is integral and indicative of quality in a power supply.

To perform the above tests, the methodology will be as follows:

Test Setup

I7 4770k @ 4.5GHz



8GB (2x4GB) Kingston HyperX Beast 2400MHz CL10

1 x 250GB Samsung 840 EVO


Voltages will be monitored via a multi-meter and the AC power draw will be monitored via a power monitor when drew from the wall.  For the idle test, the system will be simply booted up and let to run into windows and after 5 minutes when the power draw has leveled out, the readings will be taken.

To load and apply power to the power supply, a combination of IBT and Furmark will be run to put as much strain on the power supply as possible.  After 10 minutes the readings will be taken and to ensure maximum strain, the CPU will be overclocked to 4.5GHz.  Depending on the power of the power supply, multiple graphics cards could be used in line with how comfortable I feel the power supply will cope with such load.

ATX themselves specify that a fluctuation and variable of 5% is acceptable so to number crunch it means that:

3.3V = 3.135V-3.465V is acceptable

5V = 4.75V-5.25V is acceptable

12V = 11.4V – 12.6V is acceptable.

Any readings outside of these figures will be an automatic fail.

3.3V = 3.411v
5V = 5.062v
12V = 12.21v


3.3V = 3.262v
5V = 5.22v
12V = 12.44v

As you can see the readings are all in ranges specified as being acceptable by ATX. While DEEPCOOL may not be well-known for their PSUs (yet) this particular one does also carry an 80PLUS bronze rating so these readings are to be expected and should ensure there is no worry in the performance the DA500 can offer.
