Introduction and Features
The new Seasonic PRIME 750W Titanium PSU is simply the best power supply we have tested to date. Sea Sonic Electronics Co., Ltd has been designing and building PC power supplies since 1981 and they are one of the most highly respected manufacturers on the planet. Not only do they market power supplies under their own Seasonic name but they are the OEM for many other big name brands.
Seasonic’s new PRIME lineup is being introduced with the Titanium Series, which currently includes three models: 850W, 750W, and 650W (with more to follow). Additional PRIME models with both Platinum and Gold efficiency certifications are expected later this year with models ranging from 850W up to 1200W. Wow – we are already looking forward to getting our hands on a couple of these!
The power supply we have in for review is the PRIME 750W Titanium. This unit comes with all modular cables and is certified to comply with the 80 Plus Titanium efficiency criteria; the highest available. The power supply is designed to deliver extremely tight voltage regulation on the three primary rails (+3.3V, +5V and +12V) and provides superior AC ripple and noise suppression. Add in a super-quiet 135mm cooling fan with a Fluid Dynamic Bearing and a 10-year warranty, and you have the makings for an outstanding power supply.

Introduction and Features
SilverStone is a veteran in the PC power supply industry and they continue to offer a full line of enclosures, power supplies, fans, coolers, and PC accessories. They have raised the bar in their Strider power supply series, which now includes three 80 Plus Titanium certified units, the ST60F-TI, ST70F-TI, and ST80F-TI. These three units are billed as being “the world’s smallest 80 Plus Titanium, full-modular ATX power supplies”; with a chassis that is only 150mm (5.9”) deep.
The 80 Plus Titanium efficiency standards were introduced in 2012 and are the most demanding specifications to date. In addition to raising the efficiency requirements at 20%, 50% and 100% loads, the Titanium standard adds a new requirement at 10%. This insures that a Titanium certified power supply will operate with at least 90% efficiency over the full range of loads and deliver up to 94% efficiency at a 50% load.
I’m also happy to report that SilverStone is now providing a 5-year warranty on both the Strider Titanium and Strider Platinum series power supplies; up from their standard 3-year warranty.
SilverStone ST60F-TI Power Supply Key Features:
• 80 Plus Titanium certified for super-high efficiency
• Compact design with a depth of 150mm for easy integration
• All-modular, flat ribbon-style cables
• 100% all Japanese made capacitors
• Strict ±3% voltage regulation and low AC ripple and noise
• Powerful single +12V rail
• Four PCI-E connectors for multiple GPU support
• Safety Protections: OCP, OTP, OPP, UVP, OVP, and SCP
• Quiet 120mm fan with Fluid Dynamic bearing
• 140mm dust filter
• 5-Year warranty

SilverStone introduced a 700W SFX-L power supply at CES in January, and with that SX700-LPT PSU now officially released the company has raised the bar again as no less than 800W is coming to the SFX-L form-factor.

SilverStone's SX800-LTI not only offers a massive 800W, but does so with an 80 PLUS Titanium certification (!). The power supply pushes this massive wattage along a single +12V rail, and the SX800-LTI features a fully-modular design for a clean build. An added benefit to the SFX-L form-factor, other than the potential for these powerful designs, is the use of a 120 mm fan, which allows for much quieter operation under load compared to the smaller SFX variant.

We are now approaching full ATX power with these SFX-L PSUs, and indeed the 800-850W range should be all most users would need for even a dual-GPU system (especially as we enter the era of 14-16nm GPUs with their lower power requirements).
No word yet on price or availability.

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.
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.
