Testing and Usage
Since the PSU has only one PCIE connection on it I had to dig out an older video card that used only one PCIE connection, it was my Nvidia 8600GTS. My other cards all have two PCIE connections for power.
So here’s the PSU and you can really see the smoke graphics here.. I don’t understand what they were thinking mixing smoke and burning with a PSU?! Makes no sense to me…
The rest of the system is an EVGA P55 motherboard with a Core i5 750 CPU.
To test this PSU I used AIDA64 stress test of benchmark.
First I used the CPU only test. I’ve got a graph and chart showing the testing results:
I then used the combination CPU and GPU test to really stress the system.
Tolerances for power supplies are:
+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 PSU is within tolerances but it never actually reaches 3.3v or 5v, it’s always under even at idle and I don’t care for that at all. It worries me really.
The 12v line is always over 12v which is fine, better to be over I think than under.
The fan seems to work fine, it runs quiet even under load.
