Seasonic FOCUSes on quality in their new SGX PSU

Subject: Cases and Cooling | March 11, 2019 - 03:04 PM |
Tagged: FOCUS SGX, seasonic, modular psu, 80 Plus Gold, 650W

Given its small size, having four PCIe connectors, six SATA connectors, and three Molex connectors on the Seasonic FOCUS SGX is no mean feat.  That will give almost any SFF build more than enough power, or even a full sized build if you prefer a small PSU for whatever reason.  The 10 year warranty indicates Seasonic has a lot of faith in this unit, and [H]ard|OCP's testing shows it is deserved.  You will pay a little more for the FOCUS SGX but in this case it is actually worth it.

"Seasonic is FOCUSing more on small footprint high output power supplies, and the new FOCUS SGX series is targeting the small form factor market once again. This beefy 650 watt unit is fully modular, packs a 10 year warranty, is diminutive in size, had good efficiency, and comes complete with an ATX adapter plate as well."

A little bit of power for a little bitty system

Subject: Cases and Cooling | February 8, 2019 - 04:39 PM |
Tagged: modular psu, corsair, SFX, SF450, 450W, SFF

SFX PSUs are great for small form factor builds, at 4" long it will fit into those smaller systems and in the case of this SF450 from Corsair, the 17" long cables allow you to cleanly route them through the chassis.  This is an updated model, you can find the previously released SF450 still on the market and unfortunately for the 2018 model, it is about $30 cheaper. 

Is there anything to the updated model which justifies the increase in price? Check out [H]ard|OCP's full review for the answer.

1548377198us1pizj64c_2_9_l.jpg

"The Corsair SF450 SFX is, as you might have guessed from the "SFX" part number, a computer PSU built specifically with small form factor systems in mind. Corsair promises high power density along with "low noise," which are two qualities that many SFF builders are likely looking for. It also brings has Platinum level efficiency and is fully modular."

Tagged: ROG THOR, asus, 1200w, modular psu

ASUS haven't put out a PSU in quite some time; which changed at CES when they showed off the 1200W ROG THOR PSU at their booth.  There is a lot to this PSU, from an OLED on the side which will display how much wattage is currently being drawn from it to a the huge assortment of power cables.  As you can see on the back, there are a dozen SATA power connectors in addition to eight 6+2 PCIe power connectors and extra 12V for your motherboard.  On the other hand, it is priced at over $300!

If the sticker shock hasn't finished you off, [H]ard|OCP put it to the test, and it did very well.

Seasonic's Focus Plus series shows Gold can be better than Platinum

Subject: Cases and Cooling | October 18, 2018 - 02:31 PM |
Tagged: seasonic, FOCUS PLUS, 550W, modular psu, 80 Plus Gold

Seasonic have added a 550W PSU to their Focus Plus lineup of petite PSUs.  Measuring a mere 5.5" in length it uses a 120mm fluid bearing fan for cooling and is completely modular.  Inside you will find Nippon Chemi-con components which may account for why this unit outperformed similar ones on [H]ard|OCP's test bench.  Even better news is the price, running around $80 including shipping, which makes this PSU a solid choice for system which doesn't require an obnoxious amount of power.

1539570450budtt6bnuo_2_8_l.jpg

"Small computer power supplies that are entirely modular are the cornerstone of Seasonic's Focus Plus series. We are reviewing the Gold variant today rated at 550 watts that has a modern design and with hybrid silent fan control with a fluid dynamic bearing fan. Is the smallest PSU in the Focus Plus series making the cut?"

The Nightjar sings again; 450W of sweet silence

Lee just posted a review of one of SilverStone's passively cooled Nightjar PSUs, the NJ450-SXL which grabbed a Gold Award for its performance and design.  If his tests somehow didn't convince you of just how impressive this tiny, fanless 450W PSU is then please head over to [H]ard|OCP as they just unstrapped this unit from the bed in their torture chamber.  Sure it is expensive for a 450W modular PSU but there is simply nothing else to compete with the quality of this Nightjar in silent, SFF builds.

No, the naming of the Corsair RMx Series 750W does not imply RMA

Subject: Cases and Cooling | August 23, 2018 - 03:14 PM |
Tagged: modular psu, corsair, RMx Series, 750w

The RMx naming separates this PSU from the RMi lineup which includes Corsair's Link which reduces the price somewhat and the 850W model was good enough to receive a Gold Award from Lee.  [H]ard|OCP tested out the 750W member of this family, enough power for many builds, to see if it matched the quality of its big brother.  Their tests showed a solid PSU that met all the requirements for a pass and a Silver; though it does have a small problem. Last years Corsair TX750M is every bit as good and at a lower price with only one possible drawback, the ATX power connector is not modular.  This will not matter as all motherboards like to have their power in order to POST.  Check out the full review here.

1533755825h2u0f0xgzo_3_8_l.jpg

"Corsair has been bumping up its street cred lately with PSU designs that are up to HardOCP standards. Today we have its latest 2018 version of the RM series PSU rated at 750 watts. It features Gold efficiency, a fully modular design, has a 10 year warranty, and carries with it a fully modular design, all for the price of $110."

NZXT Announces the E Series Digital PSUs

Subject: Cases and Cooling | July 18, 2018 - 02:39 PM |
Tagged: 80 Plus Gold, nzxt, E Series, modular psu, CAM

NZXT launched a trio of 80 PLUS GOLD PSUs, with 500W, 650W and 850W models

E850_vents-down-left-45.jpg

These PSUs all support NXZT's CAM software which allows a Windows 10 machine to closely monitor your system's power usage.  These E Series PSUs contain a Texas Instrument UCD3138 DSP which can monitor the power usage of the various components powered by the PSU and let you see how much power your GPU, CPU and other components are drawing.  This can be very handy for both the overclocker and the energy conscious user, ensuring that the power management tweaks you applied to a component are actually working.  CAM also lets you manage your fan curve from the default setting which keeps the fan from spinning until there is at least 100W of draw on your PSU.

specs.PNG

All three modular PSUs are built with a single 12V rail for added stability and performance and come with a 10 year warranty. All models are currently available from NXZT, the E500W at $124.99, E650 at $139.99 and the E850 for $149.99USD.

Los Angeles, CA – July 17, 2018 – NZXT today announces a new line of digital ATX PSUs designed to provide PC builders with real-time power monitoring and control. The E Series lineup includes 500W, 650W, and 850W models, all 80 PLUS Gold certified. For these PSUs, NZXT partnered with Seasonic, one of the most highly-regarded PSU manufacturers, and worked with them to enhance their Focus+ Gold platform and PMBus architecture, adding a powerful Texas Instruments DSP and USB connectivity.

“The PSU is a critical part of your PC. Our goal for creating a smarter PC capable of automatically responding to the demands of the application--whether you are browsing the web, drafting email, or playing your favorite game--includes adding control and monitoring to devices that are integral to the system,” said Johnny Hou, founder and CEO of NZXT. “Our E Series PSUs are another step in completing this vision. You can track the performance of the PSU in real time, monitor temperature and total power-on hours, and even enable multi-rail OCP for additional protection of key components using CAM--our innovative software solution at the heart of our smart PC.”

NZXT E Series PSUs Key Features

  • Active monitoring for the 12V, 5V, and 3.3V rails
  • Total power-on time tracking enabled using the embedded real-time clock (RTC)
  • Digital multi-rail over-current protection (OCP) for all three 12V outputs, with adjustable thresholds for the 12V CPU (4+4 pin) and GPU (6+2 pin PCIe) connections
  • Japanese capacitors rated at 105°C
  • 80 PLUS Gold certification
  • Fully modular design means you use only the cables you need
  • 10-year Warranty and NZXT Service and Support

MONITOR YOUR PERFORMANCE The E Series uses a powerful digital signal processor (DSP) providing real-time wattage indicators for the three 12V rails, along with total uptime and internal temperature. Compare CPU and GPU power draw to their rated TDP and track historical data using CAM.

SAFER POWER In addition to providing high-precision monitoring, the onboard DSP lets you enable independent over-current protection (OCP) for the 12V output to the motherboard, CPU, and GPU, providing even better protection for your expensive components.

RELIABLE AND EFFICIENT All 80 PLUS Gold certified E Series PSUs are built using Japanese capacitors, rated to 105° C, providing long-term durability and reliability, and are backed by a 10-year limited warranty.

RUN SILENT When powering loads under 100W total, the 0dB Mode provides fully silent operation. Using CAM, you can optimize your own fan curve to suit your system or choose between the Silent, Performance, or Fixed preset modes. ALL THE ESSENTIALS E Series PSUs support single- or multi-GPU builds and the fully modular design means you use just the connections you need for your build, reducing cable clutter and simplifying system building and expansion
