There is a roundup over at Legit Reviews, with seven 550-600W PSUs of which only two models will cost you more than $100.  They are a mix of 80 PLUS Bronze and Gold, some are partially modular others non-modular and of course, they offer differing power quality and acoustic performance.  In this case the most expensive PSU also came out as the winner, but pay attention to the PSU in second place which costs half as much as the Dark Power Pro 10.

"It is natural for an enthusiast to be dazzled by monsters such as the Corsair AX1200i and the Cooler Master Silent Pro M2 1500W; however, even the majority of the enthusiasts would not actually purchase such a beast. It is (or should be) common knowledge that even a very good gaming system does not demand more than 300W-350W and thus, as power supplies are being designed to optimally perform at about 50% capacity, 550W-600W units are plenty for the vast majority of gamers and common users. It is only with multiple video cards, large raid arrays and other “specialized” designs that power requirements may increase substantially. Knowing that and realizing the need to offer our readers insight on products which truly are of interest to them, today we bring you a roundup review of seven quality 550W-600W power supplies..."

The Enermax Coenus; decent price, decent features

Subject: Cases and Cooling | June 24, 2013 - 01:49 PM |
Tagged: enermax, Coenus, atx

Enermax's new case, the Coenis, stands 478 x 234 x 488mm (18.8 x 9.2 x 19.2") which should give you plenty of space for large coolers and larger GPUs.  With 10 drive slots total you can also fit quite a bit of storage into the case as well.  This case puts the PSU at the bottom of the case, with a vent hole directly beneath it which should hopefully isolate a lot of the heat produced from the rest of the case, beneficial for those thinking of using watercooling.  For $70 you can have this case, which picked up a Silver from [H]ard|OCP.

"Enermax marches on in its war against "plain old" ATX computer case. Today we have a chassis that is fit for a king, Alexander the Great to be specific. This case has bottom draft cooling leading its "advanced cooling system," along with a fine feature list. Alexander was undefeated in battle, will Enermax retain that legacy?"

Computex 2013: Noctua Heatsinks. Late, "Cool" Story

Subject: General Tech, Cases and Cooling, Shows and Expos | June 22, 2013 - 01:43 PM |
Tagged: noise cancellation, noctua, computex 2013, computex

Update (June 22-2013, 4:43pm EDT): I was contacted by Noctua about the TDP ratings... quoting from their email:

As for the question regarding the TDP rating of the original NH-D14, I'd like to stress that the cooler can *easily* handle any 130W CPU! Our D14 is renowned to be among the best performing heatsinks for overclocking on the market and and many users have pushed their CPUs well beyond 250W using this cooler.

Noctua apparently does not like including TDP values for their coolers because it varies heavily on the conditions (such as, of course, room and case temperature). It makes sense, of course, because then customers would go looking at reviews and see what overclocks were achieved with the system.

***

Yes, I know Computex is long over, but I missed something that I want to cover.

Noctua has been teasing active noise cancellation (ANC) for their CPU coolers for quite some time now; Tim published his brief thoughts, 13 months ago, on their press release leading up to Computex 2012. The prototype, this year, is a full unit rather than the fan from last year.

This design is a modified NH-D14 cooler with added technology from RotoSub AB to sample its own noise and destructively interfere. According to Noctua, this will be the first ANC cooling unit for a CPU. The plan, as their press release suggests, is to release a cooler with the model named "R-ANC" after its (R)otoSub (A)ctive (N)oise (C)ancellation (R-ANC) technology. To me, this seems like a confusing choice in name as it breaks away from their existing standard and limits choice in name for future models based on this technology. Personally, I would have preferred to see "NH-D14R" or "NH-D14ANC", but alas I am not a marketer.

Also, in the process of researching for this article, I have been unable to find a canonical TDP-rating for this device. I was not too surprised to have a difficult time finding it for this unreleased product, but TDP is even omitted from the established, albeit louder, default NH-D14. Some sources claim this cooler can support an Intel i7 Extreme processor, which typically requires a 130W thermal dissipation; other sources say you should be somewhat cautious with this cooler with CPUs >95W TDP; some even claim it is great for air-only overclocking. Rolling all of these sources together, assuming a kernel of truth in each, I would assume this cooler (and, by extension, its upcoming R-ANC variant) would be good for decent air-only overclocks until you reach the -E series.

But, grain of salt, have some.

No word of pricing, but Noctua believes they will have it available spring/summer of next year. For some reference, the default NH-D14 can be found for about $75-$100; expect the R-ANC to be slightly north of that.

Giada D2308 Is a SFF Router-Sized Mini PC With Haswell CPU and a Discrete GPU

Subject: Cases and Cooling, Systems | June 20, 2013 - 12:42 AM |
Tagged: Intel, haswell, gtx 650, giada

Giada Technology has launched a new small form factor desktop PC with its upcoming D2308. The successor to the Giada D2305, the D2308 is a tiny PC that can be used for a variety of workloads. The mini PC, with up to a 70W system TDP, features an Intel "Haswell" processor and a discrete NVIDIA GPU (most likely mobile parts), which makes it a fairly powerful machine for the size!

The D2308 is enclosed in a black chassis with curved edges. Three Wi-Fi antennas stick up from the back of the PC. It looks rather like a home router or the mintBox PC, actually.

Giada D2308 SFF Mini PC.jpg

Internally, the Giada D2308 uses an Intel Core-i5 or Core i7 Fourth Generation Core CPU, a NVIDIA GTX 650 GPU with 1GB of video memory, up to 16GB DDR3 memory (in two SODIMM slots), a Realtek ALC662 5.1 HD audio codec, TPM module support, and two mini-PCI-E connectors for things like wireless cards or storage drives. The SFF PC can also accommodate a single 2.5" mechanical hard drive or SSD.

According to eTeknix, external IO includes two USB 2.0 ports, three USB 3.0 ports, a SD card reader, two HDMI video outputs, a Gigabit Ethernet port, and analog audio outputs. Pricing and availability have not yet been announced.

I have reached out to Giada for more information on the small form factor PC, but did not hear back from them in time for publication. I will update this post if the company responds to our questions. Although the D2308 is not a fan-less PC, it appears to have good hardware and would do well at a variety of HTPC, desktop, or office PC tasks.

Update: A Giada PC representative responded to our request for more information to let us know that the SFF PC uses the fourth generation Core i5/i7 processors and HM87 chipset along with NVIDIA GTX 650 graphics. It should be available towards the end of July.

Tagged: Passive, Logic Supply, Ivy Bridge, fanless

Logic Supply recently responded to customer requests for a high-end passively cooled system with its new LGX ML250 fanless PC. The new system is intended for industrial and mobile computing work where you need a rugged system that can be used in a wide range of environments.

LGX ML250.jpg

The LGX ML250 uses a metal chassis that doubles as a heatsink for the CPU. On the front of the case is a single power button and two USB 2.0 ports. On the rear IO panel, users are presented with:

  • 2 x COM ports
  • 1 x DisplayPort
  • 1 x HDMI
  • 1 x DVI
  • 1 x PS/2
  • 4 x USB 2.0
  • 2 x USB 3.0
  • 2 x RJ45 LAN jacks
  • 3 x analog audio outputs

Internally, the fanless PC uses an ASRock IMB-170 motherboard, Intel Sandy Bridge or Ivy Bridge CPUs, up to 16GB (2x8GB) DDR3 memory, and (up to) either a 1TB mechanical hard drive or 120GB SLC SSD for two SATA drive slots.

CPU options include the Sandy Bridge Celeron B810, the Ivy Bridge Core i3-3120ME, or the Ivy Bridge Intel Core i5-3610ME at 2.7GHz. The PC also includes Wi-Fi via a mini-PCI-E card. It can be pre-installed with your choice of Windows 7/8 or Ubuntu Linux operating systems. The LGX ML250 is rated for 40-degrees Celsius environmental temperatures.

Mr Walsh of Logic Supply stated that the company received numerous requests for a sub-$1000 machine with decent specs, IO, and with a fanless design. "The default config uses one of the new industrial-series ASRock boards -- the IMB170. From what I can tell, few IPC companies are using these boards in fanless systems, which is amazing given their price/performance specs."

The ML250 starts at $773 and is available for pre-order now. The price tag is steep, but it is a full system that is mostly aimed at industrial applications.

[H]ard|OCP recently tried out the two new Kraken coolers from NZXT, the non-i versions of the X40 and X60.  The smaller X40 will possibly be more popular as its smaller size will allow it to be used in conjunction with more cases but the X60 should not be shunned just because it is big.  You might shun it because of its higher price, arguably there are better coolers at the same price point.  The X40 on the other hand walked away with a gold award as not only does it perform well, its price is similar to some high end air coolers.  Check them out here.

Streacom Unveils Cube-Shaped DB4 Fanless (HSF) Chassis

Subject: Cases and Cooling | June 10, 2013 - 11:54 AM |
Tagged: streacom db4, streacom, hsf, Fanless PSU, fanless, cpu cooler

Streacom recently showed off a new cube-shaped case called the DB4. The new case measures 250 x 250 x 250mm (a bit under 10 inches cubed) and doubles as a passive heatsink for internal components.

The Streacom DB4 is a large cube with vertical finned sides that is held aloft by a thin angled bar. The case is intended to be used as the base for a passively cooled desktop PC. Each side of the cube-shaped DB4 case can cool 65W TDP parts, for a total cooling potential of 260W. In addition to being able to cool processors and low-end graphics cards passively, the case also cools the bundled ZeroFlex 250W fanless power supply.

Unfortunately, Streacom is not showing off the internals or detailing how the PC components are connected to the side(s) of the case. When asked for details by Fanless Tech, Streamcom responded that "we will reveal the internal alyout after all patents are through."

Streacom expects to have the case available for sale sometime between late September or early October for 200 Euros. This is a neat case that is not only fanless, but a work of art. I could see myself using this. What do you think about the Streacom DB4?

Following Intel's announcement of new Haswell sleep states, various power supply manufacturers have released compatibility lists detailing which PSUs are able to deliver the low load necessary to support the power sipping sleep states on the 12V rail (which has not been much of a concern until Haswell).

One such PSU manufacturer was Seasonic, who has quite a few Haswell-ready power supplies across several lineups including its Platinum, G, and M12II series, among others. Included in that compatibility list were two new power supplies that Seasonic is showing off at Computex this week: the Seasonic Platinum 1200 and Seasonic M12II Bronze Evo Edition.

SeaSonic Platinum 1200

The Platinum 1200 is a high-end modular power supply that is capable of powering beefy multi-GPU setups. It is 80+ Platinum rated and is up to 92% efficient at 50% load.
