Will PC Power and Cooling be Silenced?

PC Power & Cooling have been providers of high quality PSUs for a long time and are keeping up the pace, recently with the updated 750W Silencer Mk III.  They have a unique style, black and white colouring and a proprietary connector for their modular cabling that both looks and connects better than some of the recessed plastic connectors seen on other models.  Unfortunately since OCZ purchased the company they have gone from being the PSU all other companies try to match to a mid-range supplier that provides decent PSUs but lack the incredible quality they once possessed, as you can see by [H]ard|OCP's Pass marking without an award.  This may well be one of the last models you see labelled PC Power & Cooling, with OCZ's bankruptcy the continuation of the PSU business is in doubt.

"PC Power & Cooling is back on our test bench today and it has been a while. Today it is promising "industrial-grade performance and stability," with "ultimate efficiency," and "ultra-quiet operation" with its Silencer Mk III 750 watt PSU. We put it to the test to see if OCZ has done anything to return its PSUs to your next build."

Tagged: PSU, modular psu, CS-M Series, corsair

Fremont, California — November 7, 2013 — Corsair, the most awarded PC power supply brand in the world1, today announced the new line of CS Series Modular power supplies (PSUs) in 450, 550, 650 and 750 watt models. Designed to be exceptionally energy efficient and simple to install, the new CS Series are the most affordable 80 PLUS Gold certified PSUs in Corsair’s line of high-performance PC components.

The CS Series Modular PSUs are designed to deliver stable, continuous power with 80 PLUS Gold certified power efficiency to minimize energy waste and lower electrical bills. The new PSUs are cooled with a 120mm sleeve bearing fan that runs at low speeds during typical loads, keeping the PSU nearly silent during everyday tasks. The CS Series meet the latest ATX power specifications and are compatible with the latest AMD and Intel processors, with full support for the low-power modes of the latest 4th Generation Intel Core processors.

The CS Series PSUs feature a semi-modular cable system with the core motherboard power cables (24 pin and 8 pin EPS12V) permanently attached and include modular flat cables that can be attached for powering other devices such as graphics cards, SSDs, hard drives, and fans. The modular design enables users to add just the cables required for their PC, which combined with the black flat cables, creates PCs with reduced cable clutter, a cleaner look, and better airflow.

“The CS Series Modular PSUs deliver 80 Plus Gold efficiency and Corsair quality at Bronze level prices,” said Aaron Neal, Corsair’s global product manager of PSUs. “They are perfect for users that want reliable, energy efficient power for their PCs at a price that won’t break their budget.”

The GM series feature a semi-modular design with a permanently attached ATX and CPU cable paired with modular ports for attaching the flat ribbon power cables with SATA, Molex, and PCI-E power connectors. The power supplies have a single 120mm cooling fan and a 3D circuit board that eliminates some internal cabling and improves cooling as a result (according to Cooler Master). The 80+ Bronze PSUs have a single 12V rail design that can deliver up to 62 amps on the 12V rail. They are also compatible with Haswell’s C6 and C7 sleep states.

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

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."

Antec's High Current Pro 850W Platinum is worth its weight in ...

Tagged: antec, HCP-850 Platinum, modular psu, 80 Plus Platinum, Antec High Current Pro

If high efficiency is your preference then the Antec High Current Pro series is probably familiar to you.  Legit Reviews just reviewed their most powerful model, providing up to  850W and sporting four 40A 12V rails to power the six PCIe power connectors.  The fully modular design is great for keeping your case clean and the clear labellings on the PSU ensures you can properly balance the load between the 12V rails.  It performed admirably but the retail price of ~$200 did disappoint Legit Reviews somewhat.

HCP85005.jpg

"Today we will be having a close look at the 850W version of the High Current Pro series, the HCP-850. The HCP-850 is a modular power supply with a very long list of features and a seven year long warranty. As all of the High Current Pro products, the HCP-850 also comes with an 80Plus Platinum certification, the highest currently available on a retail product..."

Zeus loves tossing lightning bolts, SilverStone's new 1350W PSU

Subject: General Tech | September 16, 2013 - 03:36 PM |
Tagged: Zeus PSU, Silverstone, modular psu, 1350W

Way back in the early stages of this year Lee reviewed a PSU that not many would need but those who want multiple cards would appreciate, the SilverStone Zeus 1350W PSU.   The 12V lines, which is what GPUs care about are split into 6 with each able to provide 30A for a peak of 105A, 1260W delivered to your cards.  Unfortunately for SilverStone [H]ard|OCP have been working on this review since February and this final review is actually of the third unit that was sent to them as the initial PSUs had major problems. 

UPDATE: Tony from SilverStone reached out to explain the exact cause of the issue. 

"... it turned out that the circuit breaker he had wouldn’t play nice with ZM1350’s higher in-rush current.  Since power supplies are essentially analog devices, there are variances in production so the third unit apparently worked as ZM1350 was borderline tripping his breaker."

With the cause known you can decide on your own if your buildings curcuitry can support this PSU.

H_Zeus.jpg

"SilverStone's Zeus series is back from a four year hiatus with a new 1350 watt PSU offering to enthusiasts. This Zeus is rated with Silver efficiency at 50°C, and comes to the alter with a host of features including modular cables to keep your build looking tidy. You can even tune the rails by hand if you wish. Time to see if heads roll."

Seasonic seems to be competing against its self with the X-Series

Subject: Cases and Cooling | August 27, 2013 - 03:56 PM |
Tagged: X-650, Seasonic X-Series, PSU, modular psu

Seasonic's X-650 PSU is fully modular, allowing you to choose exactly what cables you use though the ATX power is mandatory.  It has four 6+2 PCIe power connectors and can deliver 648W @ 54A to the 12V rail making this a solid choice for a multi-GPU system.  The performance on [H]ard|OCP's test bench was excellent, the only complaint they've had is that Seasonic really hasn't changed much about their PSUs in quite a while.  That might be a little boring for reviewers but for enthusiasts, great performance at a variety of wattage is a good thing.

H_1376852248OnesqnVojT_2_10_l.jpg

"Seasonic's X-Series computer power supply comes to us boasting a patented fully modular design that minimizes voltage drops and impedance while greatly maximizing efficiency, cooling, and overall performance. Being a Seasonic unit, we can also count on it targeting the users looking for a quiet computing experience."

NXZT's HALE90 series of PSUs is getting long in the teeth but still a contender

Subject: Cases and Cooling | August 12, 2013 - 03:36 PM |
Tagged: modular psu, PSU, NZXT HALE90, kilowatt, 80 Plus Gold

For $230 the NZXT HALE90 v2 1000W PSU needs to perform well to justify the price, especially as the 1200W model currently costs the same amount.  [H]ard|OCP has the tools to test this PSU to the limits and that is exactly what they did; the unit received a passing mark but no award as the quality of it's voltage regulation was right in the middle of the pack, no better nor worse than the competition.  It is a very efficient PSU if that is one of your prerequisites, it is rather attractive and offers a large selection of modular cabling.  Check out the full review for the exact specifications.

"The new NZXT HALE90 v2 1000 watt computer power supply has more than a few marketed points that talk it up like; clean currents, rock steady performance, eccentric design, and infused design elements. All that aside, we will put it through our brutal testing suite and find out if it is worth your hard earned cash."

Seasonic's high quality 400W PSU, the X-400FL Platinum

Subject: Cases and Cooling | July 17, 2013 - 04:48 PM |
Tagged: PSU, seasonic, X-400FL Platinum 400W, 80 Plus Platinum, modular psu

A 400W PSU seems a little under-powered when compared to the kilowatt PSUs that are commonly reviewed but there are not many systems that actually need that amount of power.  Seasonic has designed their X-400FL Platinum 400W to provide great power, efficiency and extra features in lieu of providing huge amounts of power.  The PSU is fully modular and is able to provide an impressive 33A combined from it's four 12V rails, with an absolute minimum of ripple even during the most intense parts of [H]ard|OCP's testingAt $120 it is a little more expensive than other similar PSUs but with the outstanding build quality of the PSU it is worth it.

"This new Seasonic PSU touts Platinum efficiency, a fully modular design, and a host of other enthusiast-worthy hardware features that will ring true with those looking for a what might be "the best" 400 watt PSU on the market. For those of you looking to build that truly powerful HTPC, this PSU also offers silent operation."
