Following the announcements from other power supply manufacturers, Seasonic has now released a list of its own power supplies that are compatible with Intel's upcoming Haswell processor. The new Haswell CPUs, set to launch June 3rd, incorporate new C6 and C7 sleep states that draw as little as 0.05A from the 12V PSU rail. Because of the low load, some existing power supplies will have issues with the new sleep states and could result in system instability. In light of that, many manufacturers are validating their existing lineups to determine which ones are compatible.

I cannot do it captain! I don't have the not enough power!

We have been discussing the ultra-low power state of Haswell processors for a little over a week and how it could be detrimental to certain power supplies. Power supply manufacturers never quite expected that you could have as little as a 0.05 Amp (0.6W) draw on the 12V rail without being off. Since then, companies such as Enermax started to list power supplies which have been tested and are compliant with the new power requirements.

Above is Corsair's slightly incomplete chart as of the time it was copied from their website, 3:30pm on May 10th, 2013; so far it is coming up all good. Their blog should be updated as new products get validated for the new C6 and C7 CPU sleep states.

The best part of this story is just how odd it is given the race to arc-welding (it's not a podcast so you can't Bingo! hahaha!) supplies we have been experiencing over the last several years. Simply put, some companies never thought that component manufacturers such as Intel would race to the bottom of power draws.

Enermax Power Supplies Are Ready For New Haswell CPU Sleep States

Subject: General Tech | May 3, 2013 - 08:59 AM |
Tagged: zero load, PSU, Intel, haswell, enermax, cpu, c6, c5

Earlier this week, it was revealed that Intel’s upcoming Haswell processors would feature new C6 and C7 sleep states that draw as little as 0.05A on the 12V rail. Such low power draw on the 12V rail may cause problems for existing power supplies, which are not accustomed to facilitating such low power draw (especially on the 12V line). In an attempt to clear up a bit of the confusion for its customers, Enermax has put together a list of its mid-range and high-end power supplies that meet the standards required to support the new low-power processor states.

Enermax Platimax 1000W PSU.jpg

According to the press release (seen below), the Enermax power supplies use so-called Zero Load technology that uses a DC to DC converter to support low wattage power draw. This technology has been in Enermax power supplies since the Revolution85+ series which was launched in 2008. The company claims that the power supplies deliver “rock solid voltages” down to 0W load, which is within the Intel specification of 0.05A for the CPU alone.

The list of compatible Enermax power supplies is as follows:

  • Enermax Platimax Series
    • Platimax 500W (EPM500AWT)
    • Platimax 600W (EPM600AWT)
    • Platimax 750W (EPM750AWT)
    • Platimax 850W (EPM850EWT)
    • Platimax 1000W (EPM1000EWT)
    • Platimax 1200W (EPM1200EWT)
    • Platimax 1500W (EPM1500EGT)
  • Enermax Revolution87+ Series
    • Revolution87+ 550W (ERV550AWT-G)
    • Revolution87+ 650W (ERV650AWT-G)
    • Revolution87+ 750W (ERV750AWT-G)
    • Revolution87+ 850W (ERV850EWT-G)
    • Revolution87+ 1000W (ERV1000EWT-G)
  • Enermax MaxRevo Series
    • MaxRevo 1200W (EMR1200EWT)
    • MaxRevo 1350W (EMR1350EWT)
    • MaxRevo 1500W (EMR1500EGT)
  • Enermax Triathlor Series
    • Triathlor 385W (ETA385AWT)
    • Triathlor 450W (ETA450AWT)
    • Triathlor 550W (ETA550AWT)
  • Enermax Revolution85+ Series
    • Revolution85+ 850W (ERV850EWT)
    • Revolution85+ 920W (ERV920EWT)
    • Revolution85+ 950W (ERV950EWT)
    • Revolution85+ 1020W (ERV1020EWT)
    • Revolution85+ 1050W (ERV1050EWT)
    • Revolution85+ 1250W (ERV1250EGT)
  • Enermax Modu87+ Series
    • Modu87+ 500W (EMG500AWT)
    • Modu87+ 600W (EMG600AWT)
    • Modu87+ 700W (EMG700AWT)
    • Modu87+ 800W (EMG800EWT)
    • Modu87+ 900W (EMG900EWT)
  • Enermax Pro87+ Series
    • Pro87+ 500W (EPG500AWT)
    • Pro87+ 600W (EPG600AWT)

The list includes power supplies from a number of series over the past few years that range from 500W to 1250W. I'm sure between now and the launch of Haswell in the first week of June that other PSU manufacturers will be announcing which models are compatible and which are not. Stay tuned to PC Perspective as more information becomes available!

Triathlor? Seriously Enermax?

Subject: Cases and Cooling | April 25, 2013 - 06:06 PM |
Tagged: PSU, modular psu, enermax, TriAthlor, 650W

Platimax, Triathlor and NAXN; perhaps Enermax is not gifted at picking names for their PSUs but for the most part they are known for creating solid PSUs which do the job they are intended to.  Setting aside the name, this 650W mostly modular PSU has four 12V rails that combine to a peak of 54A, 648W which is certainly enough to power a modest multi-GPU system.  [H]ard|OCP put it through their own special brand of torture and were pleased with the results, a pass on all of their testing albeit results which trail the competitions offerings.  That keeps this PSU in the running as far as performance but at a current cost of $120 and perhaps higher in the future, it is hard to recommend this PSU over ones that do not cost as much and provide power of a quality at least equal to if not better than the Triathlor.

"Today we bring you an "athletic" power supply from Enermax that weighs in at 650 watts. The new Triathlor series sports plenty of features that enthusiasts will like including Silent Cooling, Flexible Cable Management, is marketed as being Rock Stable at All Loads. Enermax ads that, "The Triathlor FC is not a blinky poser."

The upper echelon of the Seasonic X-Series, 850W of solid power

Subject: Cases and Cooling | April 15, 2013 - 06:54 PM |
Tagged: seasonic, Seasonic X-Series, 850W, PSU, modular psu

One drawback to impressing [H]ard|OCP with the quality of one of your PSUs is that the bar is now set that much higher for the next model they review.  Seasonic is one such company that has a great reputation that they have to live up to with their new X-850 PSU.  The half dozen PCIe 6+2 power plugs are a good start, as is being able to provide up to 99% of total power to the four 12V rails and the fully modular cabling is always appreciated.  The real question is how it fared on the test bench, so go find out if it just makes it or if it passes the torture test with flying colours.

H_X850.jpg

Seasonic is a long time favorite of HardOCP editors as you will find a Seasonic PSU in many builds we have done over the years. Today Seasonic pushes its X-Series forward just a bit more building its first gold efficiency rated fully modular enthusiast power supply. But will it blend?"

XFX claims there is something different about their ProSeries 650W

Subject: Cases and Cooling | March 27, 2013 - 03:17 PM |
Tagged: xfx, PSU, ProSeries 650W

The XFX ProSeries 650W PSU is mostly modular, with only the ATX connector attached, has a 135mm cooling fan and can send 98% of its total wattage to the single 53A 12V rail.  With four 6+2 PCIe power connectors you will be able to handle multiple GPUs and the 8 SATA connectors should allow you as many storage devices as you need.  Unfortunately [H]ard|OCP discovered something about the 5 year warranty which greatly displeased them; unless you register your PSU within 30 days of purchase, you only receive a 2 year warranty.  If you are strictly concerned about the quality of the power this PSU delivers and are ambivalent towards the warranty, this PSU passed [H]'s torture tests handily which is something not every PSU can claim.

H_xfx650.jpg

"XFX has long and actually very solid history of producing high quality enthusiast power supplies. We have consistently found XFX PSUs worthy of [H] Editor's Choice Awards. Today the XFX ProSeries 650W promises "One Rail, One Setup" in a PSU that is different. Let's see if that is good or bad."

A SilverStone PSU so small it uses an 80mm fan

Subject: Cases and Cooling | March 14, 2013 - 06:11 PM |
Tagged: PSU, Silverstone, SFX ST45SF-G 450W, SFF, 80 Plus Gold, modular psu, SFX PSU

If you are looking to power a small form factor system and need a fully modular PSU in order to get it into a tightly packed case as well as high efficiency the SilverStone SFX ST45SF-G 450W is a decent choice.  It is Fully modular and is an SFX PSU, which as you might remember from Lee's review means that it lacks a -5V rail, not a necessary feature in today's systems.  [H]ard|OCP granted an award to this PSU, not because it is the best 450W PSU available, which is not, but because it is the best fully modular SFX PSU they have seen and they realize sacrifices have to be made in a PSU which is barely able to fit an 80mm fan inside.  Check out the full review to see if you think this PSU is worth the price premium or if you might just consider a larger PSU for your HTPC.

"Silverstone is one of our favorite computer power supply builders as the company has a tremendous track record when it comes to high quality and quiet power for our desktop systems. Today we look at something a bit different in terms of scale, a PSU pushing 450 watts of power in a package half the size with its sights on the SFF market."

A mid-weight PSU from Seasonic, the Platinum 660W

Subject: Cases and Cooling | February 14, 2013 - 05:47 PM |
Tagged: rosewill, PSU, Platinim 660, modular psu, 80plus platinum

If the 1000W Rosewill PSU that Lee just reviewed is more power than your system needs, [H]ard|OCP has a slightly less powerful 660W 80Plus Platinum PSU you could consider that Lee has also looked at.  At $150 it is fairly expensive for a 660W PSU, but a 7 year warranty and a Platinum efficiency rating do not come cheap.  With four 6+2 PCIe connectors and up to 55A on the 12V rail and an unparalleled peak change of 0.01v this will solidly power several GPUs.  [H] was so impressed that they couldn't think of a PSU to contrast against, this unit is miles ahead of the competition when it comes to the purity of the voltages provided.

H_rosewill660.jpg

"Seasonic's new SS-660XP comes to us boasting high end PSU features in what we can consider a smaller wattage package than what we are used to seeing. This PSU has a fully modular design, great efficiency, optional Hybrid fan control allowing fanless, silent, and normal cooling modes. Does Seasonic have another winner?"

Kingwin's new Power Force PSUs arrive

Tagged: PSU, Kingwin, Power Force 850W, modular psu

Kingwin's $110 Power Force 850W PSU is not as well appointed as other 850W PSUs but is also much lower in price.  With four 6/8 pin PCIe connectors and 8 SATA power connectors some users might feel a bit cramped but with 70A of power on the 12V line it seems that the unit can be useful for many. [H]ard|OCP tested the PSU to see if it is indeed worth the purchase price and were glad to see it pass all their tests, though perhaps not with flying colours.  This is the first Power Force PSU that they have seen, if Kingwin can keep the quality high and the price low they may make some inroads into recognized PSU suppliers.

H_PowerForce850W .jpg

"While not a "go to" enthusiast brand, Kingwin has produced some excellent computer desktop power supplies over the last five years and these have usually be great values. Does Kingwin continue the trend with its new Power Force 850W model sporting good efficiency, modular cabling, and reasonable pricing."
