It has been almost a year since Lee reviewed the Corsair AX1500i, one of the best high wattage PSUs it has been his pleasure to test so it seems appropriate to remind you of it's quality with this review from [H]ard|OCP.  While the PSU is not new and still costs more than the competition at $400 the 7 year warranty is better than most.  The review is of two Corsair AX1500i PSUs, one provided by Corsair and one purchased from a retail outlet for reasons you can read about in the full review.  In the end [H] gave this PSU a pass, they felt that the unchanged price was a strike against Corsair as are the claims of the marketing team but as far as performance this PSU provided solid power in even their torture tests.

"It is not every day that a company has the moxie to come out and say that it makes "the best" of anything, but that is exactly what Corsair is saying about its AX1500i computer power supply; "The best enthusiast power supply you can own." Of course that begs one question, "Is it, or isn't it the best enthusiast PSU you can own?" We answer that."

Cooler Master has been showing off a number of new products at Computex this year, and among the new announcments are a hybrid-switch keyboard and ultra-efficient (and ultra powerful) power supply.

NovaTouch TKL Hybrid Switch Keyboard

First up is the NovaTouch TKL mechanical keyboard, which Cooler Master has outfitted with their exclusive Hybrid Capacitive switches. Cooler Master claims these are "exceptionally quiet and suitable for heavy-duty typing or gaming," and the NovaTouch TKL offers support for Cherry MX switches (though it was not clear if they will be offering it with that option upon release). Another area of interest: the NovaTouch TKL has both a standard USB and microUSB connector!

Hmm... microUSB connector, eh?

Next we have a 1200W PSU with 80 PLUS Titanium certification (which you might remember calls for 90%+ efficiency at only 10% load!).

Titanium certification makes power supplies look super awesome

The power supply is Cooler Master's first "foray into digital" PSU design, and there is even a companion app with bluetooth control and monitoring functions. Finally! Now you can while away the afternoon checking and re-checking the efficiency of your PSU from your phone...

Not surprisingly, pricing and availablity are not yet available for these new products.

Manufacturer: Corsair

Introduction and Features

Corsair announced their latest flagship power supply, the 1,500 watt AX1500i Digital ATX PSU earlier this year at CES. We recently received a retail unit to review and have spent the past week putting it through our suite of tests. The new AX1500i Digital proved to be a very interesting power supply and brings not one, but several outstanding features to the high-end enthusiast market. Over time, we all grow numb to marketing terms like “most technologically advanced”, “state-of-the-art”, “ultra-stable”, “super-high efficiency”, etc., but in the case of the AX1500i Digital PSU, we have seen these claims come to life before our eyes.

Right out of the box, the AX1500i Digital power supply is capable of delivering up to 1,500 watts of continuous DC power (125 Amps on the +12V rail). If that is not impressive enough, the PSU can do it while operating on 115 VAC mains and with an ambient temperature up to 50°C (internal case temperature). This beast was made for multiple power-hungry graphic adapters and overclocked CPUs.

The Corsair AX1500i is one of the very first power supplies to obtain 80 Plus Titanium certification, which requires a PSU to operate with at least 90% efficiency between 10% and 100% load, and with at least 94% efficiency at 50% load.

The AX1500i is a digital power supply, which offers two distinct advantages. First, the AX1500i incorporates a Digital Signal Processor (DSP) to provide digitally-controlled power. This enables the PSU to deliver extremely tight voltage regulation over a wide range of loads. And second, the AX1500i features Corsair Link, which enables the PSU to be connected to the PC’s motherboard (via USB) for real-time monitoring (efficiency and power usage) and control (over-current protection and fan speed profiles).

Silent operation (zero-rpm fan mode up to ~30% load) might not be at the top of your feature list when shopping for a 1,500 watt PSU, but the AX1500i can do it thanks to high efficiency.
