On Tuesday we announced the new Corsair TX950W power supply. We've begun shipping, and if it's not already at your favorite retailer or etailer, it will be soon.
As our press release and the web page show, the TX950W has 80 PLUS Bronze certification. This is significant — our other TX models are all 80 PLUS certified, but the TX950W is the first to wear the 80 PLUS Bronze badge. A power supply with baseline 80 PLUS certification has been tested to operate at 80% efficiency; the Bronze level of 80 PLUS certification indicates that the power supply operates at a minimum of 82% efficiency at 20% and 100% load, and 85% efficiency at 50% load.
That extra 5% efficiency can make a difference. Bronze certification was one of the design goals of the TX950W -- if you need that much power, you'll certainly appreciate the reduced heat output and the corresponding effect on your energy bill. A more efficient power supply also doesn't need to spin the fan as much to dissipate heat, so it's quieter, too. In short, energy efficiency is one of the hallmarks of a well-built, well-designed power supply.
So, we were very pleased when we got the results back from the 80 PLUS organization last week: the sample we sent them blew past the thresholds for Bronze certification and earned Silver certification, meaning that it tested at 88% efficiency at 50% load and 85% efficiency at 20% and 100% load. As of this writing, 80 PLUS.org's Corsair power supply page hasn't yet been updated, but when it is, it will be given a Silver rating by the 80 PLUS organization.
Now, we have every right to promote the TX950W as a Silver-certified PSU, but we're classifying it as Bronze. The reason is simple: our reputation is important to us, and we can't guarantee that the TX950W that ends up in your PC will meet the Silver standard. Exceeding our target in the official 80 PLUS test certainly validated the effort we've put into designing the TX950W, but we're sticking with the plan of offering you a really great Bronze-certified power supply.
