Testing and Usage

The rubber gasket just slips over the end of the PSU and it touches your case instead of the metal of the power supply, it’s supposed to dampen vibrations to help keep things quieter.

I ended up using this PSU in two different systems for my kids. The first was an older socket 939 based system with an AMD 4870 video card in it.

The second system is a bit beefier with a Socket 775 based quad core CPU and two video cards, a GTX260 and an 8600GTS that was being used for Physx. Again the system is just for my kids so it doesn’t need to be all powerful, but those cards, especially the GTX260 with dual PCIE connectors, do use a bit of power.

The system were used for regular computing and gaming so they were stressed.

I also ran AIDA64 benchmark to stress the CPU and the GPU.

The first test I ran was just the CPU test and AIDA64 gives you a nice graph but it’s small.

AIDA64 also gives you a text output which looks a lot nicer:

The 3.3v drops slightly under load for the average and even at minimum and maximum loads. The 12v line looks good and it increases voltage under load as you’d expect

The next test I ran with the combined CPU and GPU test which stresses things even further. Here’s the results for that test, graph and chart for you:

Power supplies are supposed to operate within specific tolerances and this one seems to be within those.

+12 VDC     ±5% (±0.60 V)    +11.40 V to +12.60 V

+3.3 VDC    ±5% (±0.165 V)    +3.135 V to +3.465 V

+5 VDC       ±5% (±0.25 V)    +4.75 V to +5.25 V

This Diablotek 77Watt power supply runs well within those tolerances.

I’m still using it to this day and it still works great.

The fan is 140mm in size and it seems to do a good job of keeping the PSU cool and it runs quiet while doing it. Even under load I didn’t hear the fan, it didn’t add any additional noise to the system.
