The Test
For the testing purposes, the Corsair TX650 650W power supply was installed in the system with the following components:
| Test Platform |
| CPU | Intel Core 2 Quad Q6600 @ 3.0GHZ |
| Motherboard | Asus P5K Premium |
| RAM | 4GB (2x2GB) G.Skill DDR2 1000 |
| Graphics card(s) | eVGA 8800 GTX |
| Drive(s) | 3x36GB WD Raptors ADFD in RAID 0, 2x320GB Seagate Barracuda 7200.10 in RAID 1 |
| CPU Cooling | Swiftech MCP 650 Water Pump, Apogee GT, Dual Heatercore radiator |
| Sound | Sound Blaster X-Fi XtremeMusic |
| Other Devices | Asus DRW-0804P Optical Drive, Media Card reader/Floppy Drive combo |
| Fans | 5x120mm, 1x80mm, 1x60mm, 1x40mm, Corsair Dominator RAM cooler |
| Case | LIAN LI PC-V2100B |
| Operating System | Vista Ultra 32-bit |
Idle voltages were measured by powering the system at default speeds, and voltages with no applications were running for at least 30 minutes.
The load condition was established by running loops of the SM graphics test from 3DMark06 at 1600x1200 resolution with enabled 8x AA and 16x AF and Orthos (4 cores) at the same time for 24 hours. All voltage rails were measured using a digital multimeter by tapping into various connectors.
In addition to these stressful applications running, the loaded system was overclocked and overvolted to add more demand to the CPU and graphics card.
The Corsair TX650 650W has an outstanding voltage regulation. Corsair guarantees the TX650W to deliver 650W DC power at 50°C
Voltage fluctuations were minimal and stayed well within ATX standards. The thermal performance is also great but with increasing load 120mm fan gets a bit noisy (see the noise level chart below).
