Raidmax Cobra Power 500W; can an old PSU learn new tricks?

The new Raidmax Cobra Power 500W PSU is actually a 6 year old RX-500AF with a new paintball splattered colour scheme.  [H]ard|OCP felt that really showed when they looked at the power it delivers, a single 12V rail is our preference but the 384W max at 32A seems low compared to current 500W models on the market.  That lack of power as well as other features which performed to specifications less than expected lead them to advise people to stay away from this PSU even with the attractively low price you will not be getting a great unit.

"We tread off the beaten PSU path today with a power supply from Raidmax that is part of the Cobra series. The RX-500AF-B unit sports 500 watts of "Haswell Ready" power, a Bronze efficiency rating, advertised stable voltages, a "strong single +12V rail for high-end system heavy load configuration," plus a paint ball stained exterior."

Seasonic's S12G-550; you have to pay for prime power

Subject: Cases and Cooling | February 21, 2014 - 05:49 PM |
Tagged: PSU, seasonic, S12G-550, 550W, 80 Plus Gold

With an 80 Plus Gold rating and the ability to deliver 45A on its single 12V rail the 550W Seasonic S12G-550 PSU is perfect for a mid-range rig.  A pair of 6+2 PCIe connectors gives you a choice of powering a single high end GPU or two low or midrange GPUs.  It is also relatively small, barely larger than the 120mm cooling fan it uses though some may be turned off by its non-modular cables.  At around $85 it is not the least expensive model at that wattage but [H]ard|OCP's Silver Award proves it is worth it if you want solid power for your system.

"Seasonic builds some of the best computer power supplies on the market. When do we ever get a power supply that is actually a better product than what it is marketed to be? Not often, but that is the case with the S12G-550 PSU. It is not terribly inexpensive, but it is a great value for your hard earned dollars."

CES 2014: Corsair AX1500i Announcement

Subject: General Tech, Cases and Cooling, Shows and Expos | January 7, 2014 - 12:00 PM |
Tagged: PSU, corsair, CES 2014, CES, Arc Welding, 1500W PSU

Yadda yadda arc welding yadda Allyn yadda yadda podcast bingo.

For the last seven or eight years, Corsair has released a boatload of power supplies, running the whole gamut of potential customers, since their initial HX620W release in 2006. Their current line-up is broken into eight distinct series. Some are modular, some are fully modular, and others are not. Several models hold the lowercase "i" suffix which signify USB connectivity to monitor and adjust the unit from their Corsair Link utility.

corsair-AX1500i_FPO.png

Today, Corsair is announcing the AX1500i fully modular power supply. At 1500 watts, this should be an effective upper limit on desktop power consumption. The real news is its efficiency: 94% efficient at half load on 115V input (North America). The PSU exceeds the specification set out for 80 PLUS Platinum and falls within the current draft of 80 PLUS Titanium (consumer).

It is also designed to be quiet and even fanless when drawing under 450 watts.

The suffix on the AX1500i signifies that it also integrates with Corsair Link through USB. Temperature, draw, loads, fan speed adjustments, and power efficiency are exposed to the user who wants to see a few more graphs in their secondary monitors... because if you have a single 1080p panel then you are doing something wrong somewhere.

The AX1500i is expected to retail for $449.99 in Q2 2014 and is backed by a 7-year warranty.

Press blast after the break!

Corsair Announces CS Series Modular PC Power Supplies

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.”

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

Subject: Cases and Cooling | October 29, 2013 - 05:23 PM |
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.

BQL7700_04.jpg

"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."

Corsair's RM750 struggles to match the competition

Subject: Cases and Cooling | October 19, 2013 - 03:46 PM |
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."

Corsair Announces Nearly-Silent RM Series Power Supplies

Subject: Cases and Cooling | September 14, 2013 - 02:53 PM |
Tagged: rm series, PSU, Corsiar, 80 Plus Gold

Corsair has introduced its new RM series of power supplies. The new lineup replaces the TX series and sits between the existing HX and AXi series. RM-series PSUs are optimized for efficient and nearly silent operation.

The new fully modular RM series power supplies are 80 PLUS Gold certified and range from 450W to 1000W. The PSUs reportedly use low noise capacitors and transistors along with a 135mm fan that only starts spinning under high load (what Corsair calls the “ZeroRPM Fan Mode”) such as gaming. In addition to quiet operation, the RM series supports monitoring functionality. Using Corsair Link software, users can monitor PSU fan speed and power delivery. A cable, called the Corsair Digital Bridge Cable, runs from the PSU to either the system motherboard or a Corsair Link Hub and enables the monitoring features. This cable comes bundled with the highest-end RM1000 (1000W) unit, but is an additional charge for the other RM series.

The lineup includes the RM450, RM550, RM650, RM750, RM850, and RM1000 in 450W to 1KW maximum loads respectively. These new PSUs will be available at the end of October for the following prices:

RM Series Power Supply SKU Price (MSRP)
RM450 $99.99
RM550 $109.99
RM650 $119.99
RM750 $129.99
RM850 $159.99

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.

H-Hale90_1k.jpg

"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."
