    SilverStone SX600-G SFX 600W Power Supply Review

    Introduction and Features

    Introduction

    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
    • Protections: OCP, OVP, OPP, and SCP
    • Universal AC input and Active PFC
    • MSRP $129.99 USD

    Corsair HX1200i PSU Pictured

    Here's the first picture of Corsair's second 1200-Watt PSU, the HX1200i. A notch above the HX1050W and one below the AX1200i, this unit reportedly features 80 Plus Platinum efficiency, a load-based fan, which stays off, and spools up only beyond a load threshold; and fully modular cabling, with enough juice and straws to go around for a high-end gaming PC build with three or more graphics cards. The "i" in its name denotes that the HX1200i will be a "smart" PSU, supporting the company's Corsair Link technology, which interfaces with your operating system over USB, letting you monitor load, efficiency, fan-speeds, etc. There's no word on when Corsair plans to launch it.

    500-550 watt power supplies review: 40 models tested

    Introduction

    AMD is lagging behind a little, but Intel and Nvidia clearly show what the latest trend is: better performance at a lower level of power consumption. As a result, even a 500 watt power supply is more than enough for a PC with a powerful processor and graphics card. The price of such a PSU might be as low as three tenners, or as high as 140 euros. We tested 40 individual models in order to identify the differences.
    Although Intel's fourth generation "Haswell" Core processors only offered a modest increase in performance, they did boast substantially improved performance per watt. Similarly, Nvidia's latest Maxwell-based graphics cards demonstrate that you can achieve a high level of graphics performance without having to take out a loan to pay your energy bills. Intel's flagship Core i7 model for Socket 1150 has a TDP of 88 watts, and Nvidia's GTX 980 has a TDP of 165 watts. Even after including some tens of watts for memory, storage, and motherboard, you'll barely be exceeding 300 watts. As such, a 500-550 watt power supply is more than capable of powering such a high-end gaming system nowadays, even though we would've suggested that a 600-650 watt model would have been the better choice a year ago.
    That said, you should ensure that you choose a high quality power supply. While you can purchase a 500 watt power supply for as little as 25 euros, its quality will be significantly lower than that of a more expensive model. Not only in terms of efficiency, but also in terms of being able to handle a heavy workload for an extended period of time without spontaneously dying. To illustrate, let's take a look at two of the cheaper models that we subjected to our test suite, a Codegen 500W ATX and an MS-Tech MS-N550-Val 550W. During our noise test, which forced the PSUs to operate at full power for some amount of time, both models perished.
    We thus have the following motto: a good power supply might be more expensive, but will serve you well for many years. Sure, you won't suddenly be achieving more frames per second, but you will spare yourself the annoyance of having to deal with inexplicable error messages and instability, or the spontaneous loss of power on a hot summer day.
    Prices

    Admittedly, you can also go a little too crazy. For example, you could spend some 145 euros on an incredibly high-end and completely passive power supply, but you'll never earn back such an investment. Furthermore, you can still purchase an excellent, efficient, stable, and quiet power supply for far less money. To give you an impression of the different price points, our test features 5 power supplies that cost (on average) less than 50 euros, 14 with a price between 50 and 70 euros, 10 with a price between 70 and 90 euros, and 9 that are priced between 90 and 145 euros.
    Slightly half of our test sample (21 power supplies) thus cost less than 70 euros, whereas the others cost more than that, albeit just a few cents in two cases. Taking a look at our price comparison tool reveals that the prices for each individual model may differ substantially, as you can sometimes purchase a unit for 10 to 15 euros less than its average price by selecting the cheapest shop. We'll thus use a median of 70 euros as a reasonable price for a 500-550W power supply. We'll judge a model more favourably if it is substantially cheaper than that, and more harshly if it's substantially more expensive.

    Be Quiet! Straight Power 10 800W Power Supply Unit Review


    I recall a time long ago when you would walk into a computer store and the only power supply units you'd find were low-cost OEM models which surprisingly enough would last long if you were lucky. Fast forward to today and if you visit a computer store chances are that you will find yourself in front of a wall of power supply units from a very large number of manufacturers, with power outputs ranging anywhere from 250W and up to 1500W and various 80 plus efficiency certifications. Low-cost OEM models do exist even today aimed towards casual users who don't wish to spend much on one such device but today you can also find models that cost even more than a brand new laptop. Today with us however we have something more affordable and more specifically the latest offering by our friends over at be quiet! the Straight Power 10 800W power supply unit.

    be quiet! is a premium brand manufacturer of power supplies and cooling solutions for your desktop PC. be quiet! products are convincing which is proved by reaching and defending the market leadership in PSU business in Germany for five consecutive years *. This is validated and accompanied by numerous awards for both power supplies and cooling solutions. be quiet! is awarded for five times in a row as manufacturer of the year in the power supply category by the readers of the well-known German hardware magazine PC Games Hardware. Another first and second rank in the categories “fans” and “cooler” underline the high acceptance of our products. be quiet! sticks to its name: Ten years’ experience in the field of noise reduction and silence make be quiet! products probably the most silent one on the market. Undoubted fans have a large impact of the noise levels of be quiet! products. Due we are using our specially developed Silent Wings fans in nearly all of our range. They are equipped with various noise reducing features. Thanks to these we ensure a really silent operation - our products reach the best balance between cooling performance and a virtually inaudible operation. If you choose be quiet! you can be sure to get premium quality and second to none silent operation from the quietness experts.

    The Straight Power 10 line of power supply units actually consists out of two subcategories, one with semi-modular models and one with non-modular models (cables hardwired into the chassis) all of which are 80 Plus Gold Certified. Both lines have a total of four different models available beneath them but whereas the semi-modular line includes 500/600/700/800W models the non-modular line includes 400/500/600/700W models. Moving to the sample at hand the 800W model features a total of 4 +12v rails (can deliver just over 97% of the units total power output), 4 PCI-E connectors, 135mm SilentWings PWM Fluid Dynamic Bearing fan, ErP 2014 support, ATX v2.4 support (Intel Haswell ready), Energy Star v.6 support and a full set of electrical protections (OCP/OVP/UVP/SCP/OTP/OPP). So time to see just how all these translate to real world performance.

    Corsair HX750i 80 PLUS Platinum PSU Review


    Technically, the efficiency of a PSU is unrelated to its wattage. Some of the most powerful PSUs sport the best efficiency, though. Then again, few people truly need 1000W or more, and even fewer are willing to pay a premium for output levels they have no use for.
    Also consider the fact that when you under-utilize a high-output PSU, you operate it at a power level where its efficiency is less than the advertised number. Thus, what you really need is a lower-wattage PSU - and there's a good chance that power supply is going to be adorned by an 80 PLUS Gold rating or lower. Even in the mid-range of the wattage spectrum, Platinum-class products are scarce.

    The entry-level model's look and feel are excellent. It's a well-built PSU with nicely chamfered edges. All of the cables are modular and flat, which can improve routing and airflow. You get access to two CPU cables, six 6+2 auxiliary connectors, 12 SATA plugs, eight Molex connectors and two floppy drive plugs. All of the cable lengths are generous except, perhaps, the SATA cables, which we prefer to be longer than the 33.5” we measured. At least you have 12 of them, qualifying the HX750i for use in a storage server.
    Corsair's spec sheet mentions a single +12V rail able to deliver up to 62.5A. But for system builders who prefer multi-rail supplies, you can configure the PSU to operate that way via Corsair's software (for our testing, we stuck with a single-rail arrangement). Since 62.5A * 12V equals 750W, 100% of the PSU’s nominal power can be drawn from the 12V rail.
    A seven-year warranty exceeds the industry average and may be the deciding factor for enthusiasts on the fence, faced with many compelling options.
