OCZ ProXStream 1000W Power Supply

Our second set of tests maximizes GPU load by throwing dual GeForce 8800 GTX cards in an SLI configuration into the mix. Only three of our five power supplies could compete here, as they have the necessary 4 x PCI Express power connectors in order to power this configuration (each GeForce 8800 GTX card requires dual 6-pin PCI Express power connectors).

High End Gaming-Class Test System Details Specifications and Revisions

•  1 x Intel Core 2 Duo E6600 2.4 GHz Dual-Core Processor
• 2 x Kingston DDR2-800 HyperX 1 GB Modules
• 1 x Nvidia nForce 680i Chipset Based Motherboard
• 2 x Nvidia GeForce 8800 GTX 768 MB (SLI Configuration)
• 1 x Western Digital Raptor 10,000 RPM Serial ATA Disks
• 1 x Plextor PX-755SA DVD+/-RW Drive
• Microsoft Windows Vista Ultimate Edition (32-bit)

  Test Candidates

• OCZ ProXStream 1000W Power Supply
• Silverstone Strider 850W Power Supply
• Enermax Galaxy 1000W Power Supply

Our 8800 GTX SLI configuration shows similar results as our workstation tests. This high-end gaming configuration utilizes the least amount of actual power from the line socket when the OCZ ProXStream 1000W power supply is used. There isn't a major difference between the OCZ unit and our Enermax/Silverstone high-wattage units, as all three units were able to handle this configuration without breaking a sweat. However, the OCZ unit puts up the best numbers across the board here as well.
