Price, performance and efficiency from be quiet!, the Pure Power L8 700W

Tagged: PSU, be quiet!, Pure Power L8, 700W, 80 Plus Bronze

Be Quiet! could have a value-priced winner with their Pure Power L8 700W PSU, which has enough power to handle SLI/CrossFire but with a non-modular design which should keep the price fairly reasonable.  With two 12V lines capable of providing up to 53 amps you will be able to run two powerful GPUs, though perhaps not paired flagship cards.  As far as efficiency goes, Legit Reviews found it to deserve the 80 Plus Bronze rating it carries and the power regulation and ripple were both very good for any PSU, let alone a value priced one.  You can't buy it yet but you can see the review right here.

"Be Quiet! is an European company which, despite the strange name, is a very well-known manufacturer amongst enthusiasts, mostly for their high quality (and notoriously expensive) power supply units. We had an encounter with their very impressive Dark Power Pro 10 series a few months ago; however, impressive as it was, the price tag of such a power supply would certainly drive the vast majority of users away. Today we will be having a look at the least expensive PSU series currently offers, the Pure Power L8."

The be quiet! Dark Rock Pro 2 is an imposing cooler standing 166mm tall, 147mm wide and 138mm deep (6.5x5.8x5.4") and weighing in at 1.25kg which means not all cases can accommodate it and it will dwarf an mATX board.  The two fans are mismatched, one is 135mm and one is 120mm however [H]ard|OCP's testing proved that does not mean it is a loud cooler.  It's cooling ability is quite impressive and puts it at the top of the chart; unfortunately so does its $90 price tag which is higher than other competitive coolers.  If you can find it on sale it is well worth investing in.

"CPU air cooling and huge cooler sizes have become synonymous. One thing that is not synonymous with high end air cooling are muted sound profiles. be quiet! looks to remedy this issue with its Dark Rock Pro 2 CPU air cooler that sports a tremendous 220 watt cooling capacity all in that be quiet! package."

Corsair Announces Hydro Series H75 Liquid CPU Cooler

Subject: Cases and Cooling | October 24, 2013 - 10:34 AM |
Tagged: liquid cooling system, Hydro Series, H75, corsair

Fremont, California — October 24, 2013 — Corsair, a worldwide designer of high-performance components for the PC hardware market, today announced the Hydro Series H75 dual-fan 120mm liquid CPU cooler. The easy-to-install H75 provides PC users with quieter and more effective cooling than stock CPU coolers, all in a 120mm footprint that is widely compatible with most PC cases on the market. The Hydro Series H75 will be available in November at a suggested retail price of $84.99 (USD).

H75_hero.png

The Hydro Series H75 is comprised of a low-profile CPU cooling block connected to a 120mm radiator and fan assembly via kink-resistant rubber tubing. The H75’s new cooling block is designed with a micro-fin copper cold plate and a high-quality, ceramic bearing pump that provides reliable, low-noise heat transfer away from the CPU. The slim 25mm thick radiator is surrounded by dual SP120L PWM 120mm fans resulting in design that is quieter and thinner than other dual fan coolers, and more effective at dispersing heat than single fan designs. The H75’s fans work with PWM motherboard fan headers, allowing users to control the fan speed and noise levels from their motherboard’s built-in software or BIOS.

“The H75 is a great choice for PC enthusiasts who want the streamlined features of our H60 120mm cooler but desire the additional cooling performance of a dual fan design,” said Xavier Lauwaert, Director of Product Marketing at Corsair.

The Hydro Series H75 features a simple, tool-free mounting system and wide Intel and AMD socket compatibility. Like all Hydro Series liquid CPU coolers, the H75 is completely self-contained and does not require filling or maintenance.

Seasonic PSUs Will Power HashFast Bitcoin Miners

Subject: General Tech, Cases and Cooling, Systems | October 22, 2013 - 04:10 PM |
Tagged: seasonic, Power Supplies, mining, bitcoin, asic

Seasonic (Sea Sonic Electronics) has announced a design win that will see its power supplies used in HashFast’s bitcoin mining rigs. The upcoming HashFast mining rigs feature the company’s “Golden Nonce” ASIC(s) and all-in-one water coolers. HashFast has a single ASIC Baby Jet and multi-ASIC Sierra rig. Both units will be available December 15 starting at $2,250 and $6,300 respectively.

The Seasonic power supplies are high efficiency models with Japanese capacitors and at least 80 PLUS Bronze. On the high end, Seasonic has PSUs that are up to 93% efficient. HashFast stated that it chose Seasonic for its mining rigs because of the build quality and efficiency. The Baby Jet and Sierra mining rigs allow users to overclock the ASICs, and the systems can be rather demanding on PSUs.

The Golden Nonce ASIC is a 28nm chip that is rated at 400 GHash/s and 0.65 Watts per Gigahash.

Beyond that, the companies have not gone into specifics. It is good news for Seasonic, and should mean a stable system for bitcoin miners (the 93% efficiency rating is nice as well, as it means less wasted electricity and slightly more bitcoin mining profit).

The full press blast is below for reference.

The G750M, which is the 750W PSU, has the following connectors:

  • 1 x 24 pin ATX
  • 1 x 4+4 pin CPU
  • 4 x 6+2 pin PCI-E
  • 8 x SATA
  • 6 x Molex
  • 1 x Floppy power

More information on the new GM series can be found on the Cooler Master website. As is usually the case with product launches, exact pricing and availability in the US is still unknown.

Corsair's RM750 struggles to match the competition

Tagged: rm750, PSU, modular psu, corsair, 80 Plus Gold, 750w

As the picture below makes clear, the Corsair RM750 is a fully modular PSU which lets you pick and choose exactly what cables you want present in your system.  The single 12v rail is rated at 62.5A which should handle two fairly powerful GPUs, there are four 6+2 PCIe power connectors to do so.  This unit is rated 80 Plus Gold and it did live up to that rating in [H]ard|OCP's testing.  Unfortunately the efficiency and silent operation were the only things [H] was impressed by as this unit really struggled in their testing and even those tests where it could manage a passing grade the PSU lagged behind the competition.

1383190870i0udUckypn_1_2.png

"We have all read about Corsair power supplies and it is quite likely that many [H]'ers have one in their computer case right now. Today we are looking at Corsair's newest RM series power supply rated at 750 watts. The RM is built, "fully modular and optimized for silence and high efficiency." Let's see how it handles our grueling power tests."

Check out the heatpipes on Scythe's Grand Kama Cross 2

Subject: Cases and Cooling | October 15, 2013 - 02:39 PM |
Tagged: scythe, Grand Kama Cross 2, heatsink

Scythe have made some uniquely shaped coolers in the past but perhaps not as strange as some of Zalman's designs.  This cooler has a V shape to it with the inner parts of that V being extended up until they touch the cooling fan and to give a bit more surface area for heat to dissipate to.  That could have made the cooler much shorter than other heatsinks if it wasn't for the height of the heatpipes beneath the actual heatsink.  That does give you a lot of clearance for RAM with tall heatspreaders, something many other coolers do not offer.  Check out [H]ard|OCP's review to see if the cooler is as quiet and effective as the advertising claims.

"Many times in the world of CPU cooling, heatsinks look much the same from one to the next. The Grand Kama Cross 2 caught our eye due to its very unique design and we wanted to see if there was more to it than just aesthetics. The design is somewhat reminiscent of V type engine, but let's see if it has any horsepower to back it up."
