Corsair's recently announced HX750W and HX850W modular power supply units have bagged the elusive 80 Plus Gold efficiency rating, a title enjoyed only by a few high-end enterprise-grade PSUs. To qualify for this rating, a PSU must provide an output efficiency of at least 87% at 20% load, 90% at 50% load, and 87% at 100% load. At these levels of load, the efficiency of HX750W was measured 88.04%, 90.02%, and 87.04% respectively, while those of the HX850W were 89.14%, 90.38%, and 87.06%. These are Corsair's first PSUs to get the 80 Plus Gold rating, above the 80 Plus Silver which were expected of them, when the two were announced.

A friend of mine just bought the HX850 model. He'll install it today and I'll reply here on his initial comments if it's wanted.

Very nice result. I've got a HX1000 in my rig, 80 plus Silver, but if they manage to reevamp and make a model with 80 plus Gold, I'll be picking one up. Corsair's PSU's have never failed on me, and they have a ton of faith in their products - just look at the warranty they give, 5 years!

Dammit! Why couldn't they have come out with the HX850 like a month ago!?! I would have bought that instead of the HX1000. Though I love the 1000... 80 PLUS silver is still amazing. OH well. Corsair FTW!

Nice to see more efficient rated PSU's. Corsair's are top quality and I'm sure I never hit near 50% load of my 750TX, ensuring I've got a truely efficient supply.

Awesome if I upgrade I now have more cheaper choices to go with. I was gonna pick an enermax gold psu when I went P2 but now I think Ill have to think harder. HX850 Modular with a gold rating and a bit cheaper makes more sense....decisions.
