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.

Corsair's H75 has a smaller footprint than previous models, the radiator of 120 x 152 x 25mm should fit inside even smaller cases, allowing you to reduce the noise produced in the smaller case. As well they have dropped support for LGA775, the change in mounting hardware should make it easier to install on both AMD and Intel systems. While Morry was quite pleased with the performance of this cooler considering it's size; [H]ard|OCP had a slightly different take. When they looked at the cooler in terms of price for performance they felt that there are better values on the market but do still recommend it for those who need a small, powerful cooler and are willing to shop around to find it on special.
"Corsair has been in the liquid CPU cooling game for over 10 years now. As sealed system liquid CPU coolers have become the norm among hardware enthusiasts, the competition has gotten stiff to say the least. Another thing that has changed over the years is that many DIYers are going to smaller cases for their systems; the H75 looks to address this."

The Seasonic G-450 is still more power than Josh's latest build requires but is perfect for powering a SFF system as the unit is a mere 6.25" in length. With a pair of 6+2 PCIe power connectors and 37A on the 12V rail you will be somewhat limited in your choice of discrete GPU, reasonable consider it is a 450W PSU. [H]ard|OCP found the quality on this unit to be good overall and excellent compared to other lower powered PSUs but found the pricing somewhat confusing as the G-550 is a mere $10 more.
"Seasonic is continually short on marketing but long on performance, and we are good with that. Today's 450 watt G Series computer power supply makes more sense in this new world of lower power desktop CPUs and GPUs. Does the G-450 give its users solid power in this lower end of the spectrum range at the right cost?"

The CoolerMaster Elite 110 can give your next mini-ITX system build a unique look. The squarish case is 280x260x208mm (11.1x10.3x8.2") and can house a GPU of up to 210mm in length and cooler with a maximum height of 76mm, somewhat limiting your choice of components but not ridiculously so. It can handle a 120 or 140mm fan or radiator in the front and two 80mm fans on the side and also has space for 3 HDDs or 4 SSDs. [H]ard|OCP encountered some difficulties when installing multiple HDDs but not enough to stop them from awarding this case with a Silver Award; with the caveat that you should only purchase it at the MSRP of $49.99.
"Many enthusiasts now days are trying their hands at minimizing their PC footprint. Mini-ITX motherboards have progressed a long ways in terms of stability and feature set in the last three years. Cooler Master has a new solution for those looking to minimize while not giving up cooling or features in their Mini-ITX enclosure."

Introduction, Specifications, and Contents
Corsair has added another double-width liquid cooler to their growing lineup of all-in-one solutions with the H105, joining the existing H100i and larger H110 in this category.
Image courtesy of Corsair
Initially, the H105 might leave you scratching your head. It's listed on Corsair’s site with the same $119.99 MSRP as the H100i, and both are 240mm designs featuring the same high performance fans. The similarities end there, however, as the design of the H105 is more akin to Corsair's new 120mm H75 (which we recently reviewed) than to the existing 240mm H100/H100i. With the H75 already a solid price/performance pick in Corsair’s lineup - and the various other options still available - it's reasonable to wonder exactly where H105 fits in.
While this new cooler is using the same pair of excellent SP120L PWM fans as the earlier H100i (and H80i), it's the radiator they will be connected to that should separate the H105 from prior efforts. Corsair has implemented a much thicker 240mm rad with the H105 at 35mm (vs. only 27mm on earlier products), and this added thickness should have an noticeable impact on cooling performance, and possibly fan noise as well.

Tagged: cpu cooler, NH-D15, noctua
Known primarily for large and quiet CPU coolers, Noctua is not shy to attach a pair of 140mm fans to a chunk of metal. The NH-D15, announced today, can cool just about any current, mainstream or enthusiast CPU from AMD or Intel. It attaches to the CPU with a copper plate, which is connected to several copper heatpipes, which leads into two towers of aluminum fins. It is plated with nickel to prevent corrosion (I am not sure about the bottom).
As is common for these types of heat sinks, they are daunting to look at. Of course, that is not a bad thing, unless you have a very small case, but it might make you look at your stock fan differently. Noctua is claiming that their two fans spin at a maximum of 1500 RPM and a minimum of 300 RPM. This leads to a listed maximum noise value of 24.6 dBA, around the background noise of a quiet rural area at night.
The NH-D15 will be available mid-April for just shy of $100 USD.

Tagged: Vengeance K70, corsair
Update (4/8/2014 @ 8:48 PM EDT): Some commenters pointed out that the K70 already exists and has been on sale for quite some time. That is true, however Corsair has refreshed the line, apparently adding Cherry MX Blue and Brown along with the "original MX Red". It is a new product that will be released mid-April.
No, this is not the Cherry MX RGB keyboard; we still do not know when that will come out. The K70 is a mechanical keyboard made out of blackened (anodized) aluminum with red backlights in each keycap. It comes in either Cherry MX Blue, Red, or Brown. Unlike some of their previous models, every key is mechanical. It is advertised as "100% anti-ghosted with full n-key rollover". Being a USB keyboard, it is unclear whether it actually allows every key to be pressed simultaneously or whether it is limited by the interface.
That said, previous Corsair keyboards registered as 3 USB devices and split inputs between the three to overcome 6KRO limits, thus allowing for 18-key rollover. This should be sufficient for all quadridextrous typists. For the mental image of someone typing with their eight fingers, two thumbs, and all but two of their ten toes, you are welcome.
Also, and I have said this before, but it kills me when a keyboard based on an NKRO key matrix (even if it is limited by USB) needs to describe itself as "Anti-ghosting". Anti-ghosting is a hack which prevents unintended keypresses by locking-out the keyboard when it gets confused. Many keyboards, to save money, group keys together in their grid of circuits. Basically, each key is assigned to two circuits and the keyboard can thus see which switches are pressed by their pairings. The keyboard does not know how many switches are open on each circuit, just that at least one is. Ghosting occurs when three or more keypresses cause the same signals as four or more keys. The keyboard then has two options: register all possible keypresses or jam and ignore everything (anti-ghosting). An NKRO-based matrix uses diodes to further isolate keys so that each can be individually addressed.
Thus an NKRO keyboard never needs to jam. It is immune to the conditions. Unfortunately, if they did not advertise anti-ghosting, the uninformed will think it is an inferior keyboard... rather than so superior that it is immune to the problem in the first place.
Back on the Vengeance K70, it will be available this month for $129.99 USD (MSRP).
