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 fully modular RM1000 and its bundled cables.
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:

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.
"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."

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."

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 testing. At $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."

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!!

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.

Tagged: antec, haswell, PSU
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.

Tagged: sleep state, PSU, Power Supplies, haswell, c7, c6, be quiet
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.

Tagged: seasonic, haswell, Power Supplies, PSU, 0.05A
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.
