Just over a month ago Lee took a look at Silverstone's Fanless Nightjar PSU, giving it a Gold Award.  It has now arrived in [H]ard|OCP's torture chamber so you can see how well it works with a different system.  At the lowest load level of 25% of max the efficiency was a mere 89.79% but at 50%, 75% and 100% loads it stayed well above 90% and the temperature difference was 9C between the lowest load and the highest, impressive for a fanless PSU.  In the end not only was this the best fanless 500W PSU [H] has tested, it was the overall best 500W PSU they've seen, justifying the high asking price.

"What is more quiet than a computer power supply with a fan? You guessed it, a PSU with no fan. This unit has small footprint builds in mind featuring excellent Platinum efficiency, flexible flat cables, and of course no sound profile to speak of. Does the 520 watt rated SilverStone Nightjar hold up when we put it in the incubator?"

Antec Launches HCP-1300 Platinum Power Supply For Extreme Crypto Mining Rigs

Subject: General Tech | February 28, 2014 - 12:07 AM |
Tagged: power supply, HCP-1300, antec, 80 Plus Platinum

Antec has released a new high capacity HCP-1300 Platinum power supply fit for the highest-end workstations and cryptocurrency mining rigs. The 80 PLUS Platinum rated PSU is up to 94% efficient meaning less wasted electricity and more profit for miners running power hungry GPU farms. The HCP-1300 Platinum, as the name implies can deliver up to 1300W to the system, including 10 PCI-E power connectors.

Antec HCP Platinum 1300W Power Supply.jpg

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?

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..."

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."

The second coming of the AX1200, now with software controls

Tagged: PSU, modular psu, kilowatt, Digital Power Supply, Corsair Link, corsair, ax1200i, 80 Plus Platinum

Corsair's new AX1200i PSU is 80 Plus Platinum rated and sports Link monitoring and control software as you might remember from Lee's review.  On the off chance that you would like a second opinion about the PSU, [H]ard|OCP recently published their own review.  Just like Lee they were impressed with the voltage regulation, efficiency, and DC Output quality though they were less impressed with the noise they saw during their Transient Load Test.  They also questioned the use of the Link tweaking software and while the final verdict was positive in some ways they didn't feel this PSU was as true successor to the stellar AX1200 released almost two years ago.

H_Corsair_ax1200i.jpg

"Corsair has a refresh today that talks to its high end line of high power PSUs. The AX1200i comes in touting "platinum" efficiency and "an unprecedented level of monitoring and performance customization." How does the AX1200i perform out-of-the-box and does it actually bring value at its huge price?"

Enermax hits 1350W and gets rated Platinum as well

Tagged: PSU, modular psu, enermax, 80 Plus Platinum, kilowatt, Platimax 1350W

If the 1500W EVGA SuperNova PSU that Lee recently reviewed was a little too much for you then how about the Platimax 1350W from Enermax?  It sports six 12V rails, two at 20A and the remaining at 30A, a mere eight 6+2 pin PCIe power connectors and 14 SATA power connectors. This PSU is the highest rated 80 Plus Platinum PSU [H]ard|OCP has seen, as well as the highest from Enermax and they were not disappointed.  While it shared its design with the MaxRevo 1500W which left [H] a little disappointed, the Enermax implementation was superior and this PSU walked away with an Editor's Choice.

H_EnermaxP.jpg

"Enermax is a long standing quality desktop PSU company. It not only specifies and designs power supplies it is one of the few companies that actually build enthusiast PSUs. Enermax today moves it 1350 watt giant into "Platinum" efficiency territory with the new Platimax 1350W."

XFX's pricey Platinum ProSeries PSU performs perfectly

Subject: Cases and Cooling | June 1, 2012 - 02:40 PM |

With a half dozen modified 8-pin PCI-Express connectors, 8 Molex connectors, and 11 SATA connectors the XFX ProSeries 1000W PSU will handle the needs of a powerful system.  The interior components are very similar to the Seasonic Platinum 1000W which is one of [H]ard|OCP's favourites.  As with the Seasonic, the XFX PSU carries an 80 Plus Platinum rating which testing proved to be essentially accurate as [H] was not going to quibble about a 0.6% difference on their review model.  You have to pay a bit more for this PSU but if you want to pick up a model that won [H]'s Editor's Choice and Gold Award then this PSU is a sure bet.

H_XFX1000W.jpg

"XFX has a tremendously impressive track record here at HardOCP when it comes to enthusiast class PSUs. To date, four XFX PSU reviews, three Gold and one Silver Editor’s Choice Awards. Its new 1KW ProSeries PSU features no wires! No not like that, but rather on the inside. Let’s see if SolidLink Technology is award worthy."
