Missed the live stream? You fool! But here is the reply of the event and quite honestly it turned out better than I expected. If you don't learn something about power supplies by watching this, I'll eat my shoe.
Countless readers ask us for advice on power supplies. What makes power supplies different, how do you calculate how big of a PSU you need, are single rail units the best? That is just a sample of the inquiries that find their way to us.
After months of scheduling, I was finally able to wrangle in our resident power supply expert, Lee Garbutt, responsible for basically all of the power supply testing on PC Perspective since the beginning, for a LIVE stream to talk all about power supplies!
Learn about Power Supplies with Ryan and Lee - Live Stream
10am PT / 1pm ET - July 17th
What can you expect to learn during our live stream? Here is a sample of the topics we are going to cover:
Why are PC power supplies called switchers or switching power supplies?
What qualities characterize a good PSU?
What is Power Factor Correction and is it the same thing as Efficiency?
What’s all the hype about single versus multi rail output? Which is better? And what’s a rail anyway?
Let’s look inside a PSU and show me what the main components are?
Let’s talk about how you test a PSU. What tests do you perform? What equipment do you use, etc.?
We'll be monitoring the chat room in our PC Perspective Live! page for more questions during the stream of course but if you have any pressing issues you want to be sure are addressed, please leave a note in our comments below! For those of you that CAN join us live, we have another reason to attend...PRIZES!!
EVGA was kind enough to donate a EVGA SuperNOVA 1000 G2 PSU and a SuperNOVA NEX750G Gold power supply! What do have to do to enter? Just be in the live stream and pay attention - we'll have the details there during the LIVE stream!
Again, that's July 17th at 1pm ET / 10am PT for an informative discussion about the power supplies that make all of our PC gaming goodness possible!

Tagged: PSU, Intel, haswell, evga, c7, c6, 80 Plus Bronze
EVGA recently launched a new 500W power supply called the 500B. The new ATX PSU is haswell ready and supports the advanced low-wattage C6 and C7 sleep states. The 500B, as the name suggests, is a 500W unit rated 80 PLUS Bronze for 85% efficiency under typical workloads.
Although it is not modular, it has several other enthusiast friendly features. It supports 40 Amps on the single +12V rail and has over-current and over-voltage protection. Further, it has two 6+2-pin PCI-E power connectors, a single 8-pin CPU power, and a 24-pin ATX connector along with a couple molex and SATA power for good measure. Also, the PSU fan automatically adjusts speed for low noise.
The EVGA 500B (model number 100-BR-0500-KR) comes with a 3 year warranty. Pricing and availability have not been announced. It looks to be a decent option for budget builds, and should be priced competitively. More information and additional photos can be found on this EVGA product page.

Following Intel's announcement of new Haswell sleep states, various power supply manufacturers have released compatibility lists detailing which PSUs are able to deliver the low load necessary to support the power sipping sleep states on the 12V rail (which has not been much of a concern until Haswell).
One such PSU manufacturer was Seasonic, who has quite a few Haswell-ready power supplies across several lineups including its Platinum, G, and M12II series, among others. Included in that compatibility list were two new power supplies that Seasonic is showing off at Computex this week: the Seasonic Platinum 1200 and Seasonic M12II Bronze Evo Edition.
SeaSonic Platinum 1200
The Platinum 1200 is a high-end modular power supply that is capable of powering beefy multi-GPU setups. It is 80+ Platinum rated and is up to 92% efficient at 50% load.
Sesonic M12II Bronze Evo Edition
The Seasonic M12II Bronze Evo Edition is an updated version on past models and includes two SKUs that come in at 750W and 850W. It is a fully modular unit with flat black cables and fan control tech. It is 80+ Bronze and Energy Star rated, and is compatible with Intel's 4th Generation Core processors.

Antec released two lists today covering the compatibility of both their PSUs and their notebook chargers. If you are worried that your current hardware will not support the new low power states implemented in Haswell check through the list and if your product is listed you are good to go. If not you can treat these as shopping lists for your next PSU or notebook adapter.

Be quiet!, a power supply manufacturer based in Germany, has announced that almost all of its recent power supply lineups are fully compatible with Intel's upcoming Haswell processors. The PC Perspective team has talked in-depth about the new C6 and C7 sleep states used by Haswell CPUs. However, for the uninitiated, the new Intel processors have two new low power sleep states. The lowest state, C7, draws as little as 0.05A from the 12V PSU rail. That is a good thing, but not all power supplies will be compatible with the new sleep states as such low load on the 12V rail was not a concern when the PSUs were designed and manufactured. Notably, even incompatible power supplies will still work in Haswell systems, but those computers will not be able to enter the lower-power C6 and/or C7 sleep states.
There is good news for users of Be Quiet! Power supplies, however. The following power supplies are fully compatible with Haswell and the new sleep states:
- Dark Power Pro 10 Series (all models)
- Straight Power E9 Series (all models)
- Pure Power L8 Series (all models)
- System Power 7 Series (all models)
- Pure Power L7 Series (the 630W and 730W models only)
Older Be Quiet! power supplies will still work in Haswell systems, but use of the lowest power C7 state is not recommended. Fortunately, most desktop users can live without the new low power states (which, while nice to have, the new sleep states are more beneficial to laptop users).
As the launch of Haswell approaches, more and more PSU manufacturers are releasing compatibility information. So far, the following companies have put together compatibility lists.

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.
As of the time of publication, the following power supplies from Seasonic are compatible with Haswell and the new sleep states.
Platinum Fanless Series
M12 II Evo Edition Series
Stay tuned to PC Perspective for more information on PSU and Haswell compatibility.

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.

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.
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!

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."

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.
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?"
