The Corsair TX850W power supply arrived securely packed inside a colorfully printed black and yellow box showcasing the unit’s features and specifications. The power supply is protected by thick foam inserts and wrapped in a fancy black felt bag with the Corsair logo.
In addition to the power supply the box also contains a power cord, mounting screws, wire ties, Corsair case badge, and a printed User’s Manual.
Establishing an accurate load is critical to testing and evaluating a PC power supply. PCPerspective’s power supply test bench can place a precise 2,000 watt DC load on the PSU under test. Each power supply is tested under controlled, real-world conditions up to its maximum rated load (at 40ºC), using both 115 VAC and 240 VAC line voltage. Our current suite of tests includes:
• DC Load Regulation
• DC Line Regulation
• DC Cross-load (unbalanced load)
• AC Ripple and Noise
• Power Factor
• Efficiency
• Differential Temperature
• Noise
The Corsair TX850W power supply was evaluated on both features and performance. A full range of equipment was used to test the power supply under controlled load conditions.
• (2) CSI3710A Programmable DC load (+3.3V and +5V ouputs)
• (4) CSI3711A Programmable DC load (+12V1, +12V2, +12V3, and +12V4)
• FLUKE 87-III True RMS digital multimeter (Accuracy ±0.05%)
• Extech 380803 Power Analyzer (Accuracy ±0.5% of full scale)
• Hitachi V-650F 60 MHz dual trace oscilloscope (Accuracy ±3%)
• Powerstat Variable Autotransformer, 1.4 KVA, 0-140 VAC
• FLUKE 52-II digital thermometer (Accuracy ±0.3ºC/0.5ºF)
• Extech Model 407738 digital sound level meter (Accuracy ±1.5 dB)
• Custom Lian Li PC60 enclosure to simulate real-world operating conditions
I’ve had it for 13 years and it’s still good, never issues. I’m not planning to change it yet, but maybe I will have to because of a new case.
I’ve had it for 12 years and it’s still good also. And I’ll stick with for a while longer since my next card will be a RTX 2060, so no worries so far. Amazing PSU.
i using this PSU since 2011, almost 13 years in operation and waiting if it can power a 4070 Ti Super, fingers crossed.
