Corsair HX1000W review by HardwareSecrets

We were impressed to see that Corsair HX1000W is internally practically identical to Thermaltake Toughpower 1,500 W, a unit labeled with a maximum power capacity 50% above Corsair’s model!

We are pretty confident that Corsair HX1000W is in fact a 1,500 W power supply that Corsair decided to label as a 1,000 W model because of efficiency. If Corsair had labeled this unit as a 1,100 W or greater unit it wouldn’t achieve the minimum 80% efficiency at full load that is considered by today’s standards the minimum a power supply should perform

In summary Corsair HX1000W is a practically flawless 1,000 W power supply clearly targeted to users with three or four very high-end video cards and several hard disk drives. Of course if you are building a more modest system with only one or two video cards, you should buy a more inexpensive product, which will give you a better cost/benefit ratio
