SilverStone has a long-standing reputation for providing a full line of high quality enclosures, power supplies, cooling components, and accessories for PC enthusiasts. Today we are going to mix it up a bit and focus our attention on smaller rather than larger. Not everyone needs or wants a 1,000W plus PC power supply. And if you have a small form factor case or are struggling to find room inside a cramped ATX enclosure, SilverStone’s new SX600-G SFX power supply may just be the solution you are looking for.

The new SX600-G SFX power supply was designed for small form factor cases but comes with an ATX adapter plate so it can be used in a standard ATX enclosure as well. In addition to its small size, the SX600-G features high efficiency (80 Plus Gold certified), all modular flat ribbon-style cables, and provides up to 600W of continuous DC output; pretty impressive for such a small package. Also new is the ability to operate in semi-fanless mode (cooling fan turns off at low power).

SX600-G SFX 600W PSU        Standard ATX 600W PSU

The last time we looked at a SilverStone SFX power supply was in 2012 when we reviewed the updated ST45SF-G, which was rated at 450W. SFX power supplies continue to occupy a niche market and address a slightly different set of needs than the standard ATX units we typically use and review at PCPerspective.

Here is what SilverStone has to say about their new SX600-G SFX PSU: “After releasing the breakthrough SFX power supply in 2012 with the ST45SF-G, SilverStone has pushed the technical envelope even further with yet another industry defining design in the SX600-G. This small form factor PSU has the exact same dimensions as its predecessor but its power density has increased from 567W per liter (in the ST45SF-G) to 756W per liter. The result is a standard sized SFX PSU with an incredible 600W of continuous power, a level that is capable of supporting any single graphics card system with ease.

Besides the power increase, the SX600-G comes standard with flexible, flat modular cables similar to those in the PP05-E short cable kit for vastly improved cable management in smaller cases. It also has added semi-fanless capability that was first introduced to SFX PSUs by the ST30SF so its quiet running fan can remain turned off during ideal low load or idle conditions for complete silence. As before, an ATX adapter bracket is included to enable users to install this PSU into any small or even larger cases that do not have SFX mounting holes. For the most ardent SFF enthusiasts, the SX600-G is truly a dream come true that combines the convenience of SFX size and all the top of the line features one can expect from high-end ATX PSUs into one product.

SilverStone SX600-G SFX Power Supply Key Features:

•    Supports standard SFX form factor (and ATX via included adapter)
•    600W Continuous DC output (up to 40°C)
•    High efficiency with 80 Plus Gold certification
•    100% Modular cables, flat ribbon-style
•    Intelligent semi-fanless operation
•    Strict ±3% voltage regulation with low AC ripple and noise
•    Class leading single +12V rail with 50A (600W)
•    Two PCI-E 6+2 pin connectors

At 1500W peak power, 120A max on the 12V rails, the SilverStone Strider Gold 1500W will power any system you throw it in.  There are other PSUs with that level of power but none measuring just a hair bigger than the 120mm cooling fan, a hair over 7" in length.  In [H]ard|OCP's testing they found it to have a bit more variance in the voltages than they prefer but well within spec and at as good if not better than any of the other 1500W PSUs that they have reviewed.  If you truly do need the power and can afford the asking price then you should check out the full review.

In this review we will be taking a detailed look at High Power’s new Astro GD 1200W power supply. All of the power supplies in the Astro GD Series are fully modular, have a single +12V output, and are 80 Plus Gold certified for high efficiency. There are currently sixteen different power supplies in the Astro Series and nine models in the fully modular Astro GD Series. The new AGD-1200F is king of the hill with the highest rated output of 1,200 watts.

2-Front-cables.jpg

Along with 80 Plus Gold certified high efficiency, the Astro GD1200W power supply has been designed for quiet operation. It uses a dual ball bearing 135mm fan and a smart fan speed control, which automatically switches between two operating modes: silent mode and cooling mode. Unlike some other power supplies that keep the fan turned off during low output, the AGD-1200 fan spins all the time. The Smart Fan Control adjusts the fan operation mode automatically according to the system loading and ambient temperature for quiet operation. The fan speed starts out slow and quiet and gradually ramps up as the load increases. The PSU also incorporates an off-delay fan feature that keeps the fan spinning for a few seconds after the system is turned off.

Manufacturer: Seasonic

Introduction and Features

2-Banner.jpg

Seasonic is a well known and highly respected OEM that produces some of the best PC power supplies on the market today. In addition to supplying power supplies to many big-name companies who re-brand the units with their own name, Seasonic also sells a full line of power supplies under the Seasonic name. The new XM2-1250 is the latest addition to the X-Series and features an improved Hybrid Fan control circuit and upgraded copper conduction bars on the main PCB, which together increase efficiency and performance.

The new XM2-1250 is a second generation X-Series power supply that comes with fully modular cables and a 120mm Sanyo Denki cooling fan. It is designed to provide ultra-tight voltage regulation along with high efficiency (80 Plus Gold certified).

3-Side-XM2-1250.jpg

Seasonic X-Series XM2-1250 Special Features

Ultra Tight Voltage Regulation Improved load voltage regulation keeps the voltage fluctuations on the 12V output within +2% and -0% (no negative tolerance), and on the 3.3V and 5V outputs between +1% and -1%, which (under 80 Plus load conditions) results in smooth and stable operation.

Seasonic Hybrid Silent Fan Control The industry first, advanced three-phased thermal control balances between silence and cooling. The Hybrid Silent Fan Control provides three operational stages: Fanless, Silent and Cooling Mode.  In addition, a selector switch is provided to allow for manual selection between the Seasonic S2FC (fan control without Fanless Mode) or S3FC (fan control including Fanless Mode).

Reduced Cooling Fan Hysteresis is achieved by a new fan control IC, which optimizes how frequently the fan switches on and off. At 25°C ambient temperature the fan turns on when the load rises above 30% (±5%) and turns off when the load drops below 20% % (±5%). Due to this lag in response the fan switches on and off less frequently, which reduces power loss in Fanless and Silent Mode.

Dual Copper Conduction Bars on the power supply PCB help reduce impedance and minimize voltage drop, which further improves efficiency and performance.

80Plus Gold The XM2-1250 power supply is certified in accordance to the 80PLUS organization's Gold standards, offering performance and energy savings with up to =90% efficiency and a true power factor of greater than 0.9 PF.

Full Modular Design (DC to DC) The Seasonic X-Series power supplies feature an integrated DC connector panel with onboard VRM (Voltage Regulator Module) that enables not only near perfect DC-to-DC conversion with reduction of current loss/impedance and increase of efficiency but also a fully modular DC cabling that enables maximum flexibility of integration and forward compatibility.

Seasonic XM2-1250 PSU Key Features:

•    High efficiency, 80Plus Gold certified
•    7-Year manufacturer's warranty worldwide
•    Fully Modular Cable design with flat ribbon-style cables
•    Seasonic DC Connector Panel with integrated VRMs

Cooler Master's new V-Series; good on the inside but perhaps lacking on externals

Subject: Cases and Cooling | July 28, 2014 - 05:25 PM |
Tagged: cooler master, V650S, modular psu, 650W, 80 Plus Gold

With a total rated power of 650W and two PCIe 6+2 power connectors the CM V650S seems to be aimed at entry level gaming systems but the $180 price tag suggests a high end PSU.  It is partially modular and it bears an 80 Plus Gold rating but perhaps the price also comes from Cooler Master's use of a new OEM, Enhance?  [H]ard|OCP did find it at a much more reasonable $80 on Tiger Direct but it is now out of stock and it does not seem to appear on NewEgg at all right now.   Overall there is a lot of good things to be said about the internals of the PSU but on the outside there is much left to be desired.  Check out the review but perhaps wait for the second version of the V650S before purchasing one.

"Cooler Master has been off the enthusiast radar in terms of computer power supplies for a while now. It simply walked a different line than much of the rest of the field. Today however we have one of Cooler Master's second foray back into the high end with a mid-level PSU rated for operation at 650 watts."

Tagged: PSU, antec, 750w, 80 Plus Gold, TruePower Classic

[H]ard|OCP reviewed the highest powered model of the new TruePower Classic lineup, the 750W non-modular 80 Plus Gold rated PSU which has a lot of advertising hype to live up to.  Inside it is a highly modified Seasonic G-Series with quality capacitors, though the fan is only of middling quality.  This PSU did pass every test that was thrown at it bit did not quite provide the same high performance as other PSUs [H] tested that used the same design.  On the other hand at $103 it does not cost as much either making it a good example of compromise between extreme performance and extreme cost.

"Antec comes to us today with a mid-level 750 watt enthusiast computer power supply that touts Gold efficiency. This PSU is somewhat light on marketing and heavy on features such as Japanese capacitors, "unprecedented tight voltage regulation," and low ripple and noise to "maximize your system's performance."

EVGA's 650W PSU, still sporting that strange handle

Subject: Cases and Cooling | June 5, 2014 - 03:52 PM |
Tagged: evga, EVGA SuperNOVA, 650W, NEX650G, 80 Plus Gold, modular psu

The EVGA SuperNOVA NEX650G Gold is a 650W PSU capable of delivering 20A on each of it's 12V rails with a maximum of 53A in total.  As it comes with four 6+2 pin PCIe power connectors and an extra 6 pin it should be able to handle multiple mid-range GPUs, though as [H]ard|OCP discovered it can get quite loud under full load.  As it can be purchased for under $100 it is a 'good enough' choice for many enthusiasts who don't need a kilowatt nor have a lot of money to spend.  It may not stand out in the crowd but it certainly passed every test [H] threw at it.

140003072714oFvHaTYk_2_9_l.jpg

"EVGA does not have a lot to say about its SuperNOVA NEX650G Gold Power Supply. It does however mention it being designed with enthusiast needs, and this PSU being the "the best choice to power next generation enthusiast computers" with exceptional features, and stunning efficiency. We of course will be the judge of those claims."

Thermaltake Launches Modular Toughpower Gold Series Power Supplies

Subject: General Tech | February 27, 2014 - 02:19 AM |
Tagged: toughpower gold, thermaltake, power supply, 80 Plus Gold

Thermaltake has launched three new power supplies under its Toughpower Gold series. The new models come in 550W, 650W, and 750W capacities and offer up a semi-modular design and 80 PLUS Gold efficiency ratings.

Thermaltake Toughpower Gold 750W Power Supply.jpg

The new power supplies are rated at 87% to 92% efficient depending on the load and fall under the 80 PLUS Gold designation. Additionally, the PSUs offer a single rail design to deliver stable power to graphics cards and the processor. A semi-modular design has the 24 pin and 8 pin motherboard power connectors permanently attached and connection points for a variety of additional power cables. Thermaltake has gone for a flat cable design which should mean the cables are easier to route and hide behind the motherboard tray. Other features include high quality Japanese capacitors and a reportedly quiet 140mm fan that hits 18dB under typical loads.

The 550W offers two 8-pin PCI-E power connectors while the top end 750W version supports up to four 8-pin PCI-E power connectors meaning it can easily power CrossFire and SLI multi-GPU setups.

You can find more information on the Toughpower Gold power supplies on their respective product pages.

Unfortunately, pricing and exact availability has not yet been released.

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.

1390961397zFDI3yDIHr_2_9_l.jpg

"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."
