In The Labs
Testing a 1000W power supply needs a really power hungry system. In truth this beast is targetted at the upper level of PC enthusiasts who want and demand the best for their rigs. At MaXit we have just the tool in our labs - the MaXit monsta. Some say it was forged in molten lava, that it breathes fire and can even scare old women. All we know is that it has a quad core processor, 8800GTX cards running at 650MHz and a ton of watercooling equipment. The ProXStream is not SLI Ready certified at the time of this writing but it shouldn't be a problem using this PSU in SLI rigs.
- Intel Core 2 Quad Core Extreme Q6700 @ 3.33GHz
- ASUS Striker Extreme Motherboard
- 2x 1GB DDR2 RAM @ 1200MHz
- 2x GeForce 8800GTX in SLI at 650MHz
- Xtreme Soundcard
- 3x 7200RPM HDDs
- 1x 10000RPM HD
- 1x ThermoChill PA120.3 Radiator
- 1x ThermoChill PA120.2 Radiator
- Laing DDC 3.2 Ultra with Plexitop
- Seven 120mm Fans
- Mcubed Fan Controller
- Various lighting
Installing the ProXStream was hassle-free due to the compact size. Its small footprint really does make it a great PSU for small and medium sized cabinets.
First, rail stability. All the three rails were stable and showed very little fluctuation under heavy load. The fluctuation was no more than 0.05V at any moment during the 12 hour run.
The +12V rails can handle a 20A power draw each. The +3.3V rails and the +5V rails are capable of handling power draws of 28A and 30A respectively. Even with this high end system pushing the Quad core CPU and NVIDIA cards to the max, the system remained perfectly stable no doubt thanks to the huge power reserve of the ProXStream.
Now onto noise performance. The PSU only has just a 80mm fan to cool all this power. And the little devil is noisy. If you are into quiet computing this thing will drive you bonkas. Even before we began load testing it was ramped up quiet high. I guess OCZ made a trade off between size and noise. Sure a 120mm fan would have been great but then you wouldn't be looking at such a small unit.
