OCZ ZS-750W PSU

3. Operation

We should note here that testing a PSU is not very easy and it requires use of specific equipment that would provide information about the current the PSU offers under load, the efficiency of the PSU at average operating levels as well as any power or current limits our PSU might have. Unfortunately, we don't have such a testing equipment in our labs so what we can just do is to use the device and have an idea of its performance using worst case estimations. The specific PSU has been designed to power up to dual graphics cards configurations, so we tried to add enough load to the CPU and graphics systems using a 3D Mark Vantage and PC Mark Vantage. Our test PC was also loaded with the following:

  • Motherboard: Asus P6T Deluxe/OC Palm Edition
  • CPU: Intel Core i7-920 retail
  • 2x Asus EN9800GTX
  • 3x1GB Crucial PC3-10600
  • 1xWD 80JB SATA I
  • 1xSeagate 80GB SATAII
  • Windows VISTA 32bit SP1

The following table lists the ATX specification for DC voltages (output):

 

After running both benchmarks, the monitored outputs showed us how much stress the PSU has taken. A summary of the results is illustrated below:

Minimum
Maximum
+3.3 V
V
3,23
3,29
+5 V
V
4,89
5.01
+12 V
V
11.86
12,25

Voltage regulation at +12V and 5V is within 3% range and 3.3V are a little higher at 3.6%. Overall voltage regulation is decent for the category of the ZS 750W.
