Cougar CMD Digital Power Supplies Come With Integrated Fan Controller

Subject: Cases and Cooling | March 12, 2015 - 04:52 PM |
Tagged: power supply, modular psu, Cougar, 80+ bronze

Cougar is launching its new CMD Digital power supplies in 500W and 600W versions. In a move to differentiate itself from the crowd, Cougar has packed in an integrated fan controller and the ability to monitor and control the PSU (e.g. voltage) using software.

The new power supplies are modular excluding the main 24-pin ATX and CPU cables. Both models use a single 12V rail rated at 40A on the 500W model and 49A on the 600W PSU. Cougar uses a temperature controlled 140mm fan to keep the PSU cool. The CMD Digital is 80+ Bronze certified and features various over and under current and voltage protections (OCP, SCP, OVP, UVP, and OPP).

The following power cables and connectors are included:

  • 1 x 24-pin ATX
  • 3 x 4-pin Peripheral (Molex)
  • 5 x SATA (6 on the 600W model)
  • 2 x 8-pin PCI-E (6+2)
  • 1 x 8-pin CPU (4+4)
  • 2 x 3-pin Fan headers
  • 1 x TSR temp sensor port

In all, it’s a fairly standard layout with enough amperage and PCI-E power connectors to support a high end GPU setup.

The integrated fan controller drives up to two case fans (more if you use a splitters, I suppose) that are connected to the back of the power supply. Further, Cougar provides a temperature sensor that you can place anywhere inside your case to monitor case temperature. 

Cougar UIX Analysis.jpg

Using the company’s Cougar UIX software, users can monitor and control fan speeds, monitor system component utilization (CPU, HDD, etc), monitor power consumption, adjust voltage levels, and log various power delivery stats.

Cougar has not yet released pricing, but it will be available in April.

From the features, it sounds like a decent power supply though my opinion would heavily be influenced by the included software. Despite ample computing resources, I like to run a lean system with as little running in the background as possible. If Cougar UIX sips resources and it holds up to the advertised power delivery ratings, I would consider it.

Hopefully we can get one in for review soon and Lee can put it through its paces.

The new PSU uses a fully modular design with a look towards the future. Antec is using 16-pin cable connectors for future modular cables as well as a 20+8 pin motherboard connector to accommodate future ATX motherboards that might require an additional four power pins over today's 20+4 pin boards. A 135mm fan keeps the internal components cool at high loads. Other enthusiast-friendly features include CircuitShield technology and an OC Link connector. The OC Link allows adventurous enthusiasts and miners to connect two HCP-1300 Platinum power supplies together and have them work in tandem to power a single ultra high end system (hopefully you miners attempting this are plugging the PSUs into dedicated AC circuits!).

This enthusiast PSU comes at a premium, however. In fact, the Antec HCP-1300 Platinum will set you back $312 for a single unit. On the bright side, it does come with a generous seven year warranty.

Will this beastly power supply be at the heart of your next Dream System?

Tagged: toughpower gold, thermaltake, power supply, 80 Plus Gold

Thermaltake has launched three new power supplies under its Toughpower Gold series. The new models come in 550W, 650W, and 750W capacities and offer up a semi-modular design and 80 PLUS Gold efficiency ratings.

Thermaltake Toughpower Gold 750W Power Supply.jpg

The new power supplies are rated at 87% to 92% efficient depending on the load and fall under the 80 PLUS Gold designation. Additionally, the PSUs offer a single rail design to deliver stable power to graphics cards and the processor. A semi-modular design has the 24 pin and 8 pin motherboard power connectors permanently attached and connection points for a variety of additional power cables. Thermaltake has gone for a flat cable design which should mean the cables are easier to route and hide behind the motherboard tray. Other features include high quality Japanese capacitors and a reportedly quiet 140mm fan that hits 18dB under typical loads.

The 550W offers two 8-pin PCI-E power connectors while the top end 750W version supports up to four 8-pin PCI-E power connectors meaning it can easily power CrossFire and SLI multi-GPU setups.

You can find more information on the Toughpower Gold power supplies on their respective product pages.

Unfortunately, pricing and exact availability has not yet been released.

OCZ Releases Haswell PSU Compatibility List

Subject: General Tech | June 7, 2013 - 10:58 PM |
Tagged: power supply, ocz, haswell, c7, c6

OCZ recently posted a list of its power supplies that are fully compatible with Intel's new 4th Generation Core "Haswell" CPUs and their new C6 and C7 processor sleep states. The new sleep states can draw as little as 0.05A from the 12V rail, and not all power supplies (especially older models) were built with that use case in mind. Somewhat paradoxically, as power supplies have ramped up in Wattage and power delivery characterists, other PC internals have started moving in the other direction towards increased power efficiency and lower power usage overall.

silencermkIII_850W_3892.jpg

OCZ seems well prepared for Haswell, however, with a number of PSUs that are already fully compatible with Haswell CPUs. Even going as far back as its Z Series which launched in 2009 are compatible, which is comforting.

The full list of Haswell compatible OCZ power supplies is available below.

  • MK III Silencer
    • PPCMK3S1200
    • PPCMK3S850
    • PPCMK3S750
  • MK II Silencer
    • PPCMK2S950
    • PPCMK2S750
    • PPCMK2S650
  • Fatal1ty Gaming Series
    • OCZ-FTY1000W
  • ZX Series
    • OCZ-ZX1250W
    • OCZ-ZX1000W
    • OCZ-ZX850W
  • Z Series (EOL)
    • OCZZ1000M
    • OCZZ85M

With that said, even if your OCZ (or PC Power & Cooling) power supply is not on this list, it will still work in systems that utilize Intel Haswell processors. However, you will not be able to take advantage of the new power sipping C6 and C7 sleep states.

As the launch of Haswell approaches, more and more PSU manufacturers are releasing compatibility information. So far, the following companies have put together compatibility lists.

Possible power supply issues for Intel Haswell CPUs

Subject: Cases and Cooling, Processors | May 1, 2013 - 03:07 PM |
Tagged: power supply, Intel, idle, haswell, c7, c6

I came across an interesting news story posted by The Tech Report this morning that dives into the possibility of problems with Intel's upcoming Haswell processors and currently available power supplies.  Apparently, the new C6 and C7 idle power states that give the new Haswell architecture benefits for low power scenarios place a requirement of receiving a 0.05 amps load on the 12V2 rail.  (That's just 50 milliamps!)  Without that capability, the system can exhibit unstable behavior and a quick look at the power supply selector on Intel's own website is only listing a couple dozen that support the feature. 

haswellpsu.jpg

This table from VR-Zone, the source of the information initially, shows the difference between the requirements for 3rd (Ivy Bridge) and 4th generation (Haswell) processors.  The shift is an order of magnitude and is quite a dramatic change for PSU vendors.  Users of Corsair power supplies will be glad to know that among those listed with support on the Intel website linked above were mostly Corsair units!

A potential side effect of this problem might be that motherboard vendors simply disable those sleep states by default.  I don't imagine that will be a problem for PC builders anyway since most desktop users aren't really worried about the extremely small differences in power consumption they offer.  For mobile users and upcoming Haswell notebook designs the increase in battery life is crucial though and Intel has surely been monitoring those power supplies closely. 

I asked our in-house power supply guru, Lee Garbutt, who is responsible for all of the awesome power supply reviews on pcper.com, what he thought about this issue.  He thinks the reason more power supplies don't support it already is for power efficiency concerns:

Most all PSUs have traditionally required "some load" on the various outputs to attain good voltage regulation and/or not shut down. Not very many PSUs are designed yet to operate with no load, especially on the critical +12V output. One of the reasons for this is efficiency. Its harder to design a PSU to operate correctly with a very low load AND to deliver high efficiency. It would be easy just to add some bleed resistance across the DC outputs to always have a minimal load to keep voltage regulation under control but then that lowers efficiency.
