EVGA has launched a new line of small form factor power supplies under the SuperNOVA GM series. The new power supplies are available now in 450W, 550W, and 650W models all of which are rated at 80 PLUS Gold efficiency ratings with all Japanese capacitors and built in safety technologies for OCP, OVP, OTP, OPP< SCP, and UVP protections.
The single rail (up to 54.1A on the 12V rail) power supplies utilize Active PFC (power factor correction) and DC-to-DC conversion for the 3.3V and 5V supplies. EVGA’s SuperNOVA GM PSUs are all fully modular and support SLI with two 8-pin PCI-E connections on the 450W PSU and four 8-pin PCI-E power connectors on the 550W and 650W models. A single 92mm double ball bearing fan keeps the small form factor power supply cool while the Auto ECO mode keeps fan noise at a minimum with the fan spinning down completely up to 30% load, then ramping to ~18 dBA up to around 70% load and then ramping up to 37 dBA at 100% load (for the 650W power supply).
EVGA’s SuperNOVA GM SFX power supplies come with a 7+2 year warranty (7 year base warranty plus an additional two years for a limited time according to EVGA). The GM power supplies come with a AC power cable, PSU tester, and SFX-to-ATX adapter bracket.
The power supplies are available now for $109.99 for the 450W model, $119.99 for the 550W PSU, and $129.99 for the 650W power supply. Looking around online, pricing seems to be in line with the competition at these wattages, at least when considering the premium for the SFX small form factor designs.

Perhaps the box looked a little empty when Enermax placed their SFX Revolution PSU into the packaging, so they filled up some of the empty space with a Lepa Boom wireless speaker for you to enjoy while assembling your machine. [H]ard|OCP didn't spend a lot of time reviewing the speaker as they were too busy investigating the first SFX PSU they have encountered from Enermax. Overall this PSU passed every test they tossed at it and the price on the unit is favourably comparable to two 600W units [H] tested previously so if you are building a tiny machine that needs a good amount of juice then this review is worth looking into.
"The small form factor segment has been hot for a while now when it comes to enthusiast PC builders and Enermax is entering the SFX fray today with the Revolution SFX 650W PSU. It touts fanless modes under 30% load, 100% Japanese capacitors, and complete flat flexible cables for easier routing in tight cases."

With small form factor systems growing in popularity, the market for SFX PSUs is increasing as well. FSP have just released their new Dagger family of SFX PSUs with two models, a $100 500W and a $110 600W. Both of these PSUs feature single 12V rails and are rated 80 Plus Gold, the internals are based off of server quality PCBs and offer DC to DC power.
They ship with a removable backplate to allow them to be used in full sized builds as well, with the small size of the PSU leaving more space in your case for cooling solutions and air flow. The PSU itself is cooled by an 80mm fan, about as large as you can fit in the 125x63.5x110 mm shell.
The Dagger is fully modular, with flat cables to make cable management even easier. The PSU ships with two PCIe 6+2 power connectors, five SATA, two molex and a floppy plug in addition to the motherboard power cables. You can check out the video below, or click through to read the full PR from FSP.

You may remember Lee's review of Silverstone's SFX PSUs back in November, but in case you do not you should revisit his review as well as this one recently posted by [H]ard|OCP. The SFX PSU form factor for SFF cases is more of a mouthful than it is a physical object for at 125x63.5x100mm it is wider than it is deep. That tiny package does hold a decent amount of power as it can provide the full 450W it is capable of to the 12V rail at 37.5 amps, more than enough power for even higher end GPUs put onto a mATX board. Not only did it pass [H]'s torture test, it is also very competitively priced.
"SilverStone is back today with one of its "smaller is better" computer power supplies that can be used in SFX form factor systems but also comes with a mounting bracket that makes it ATX friendly out of the box. This PSU is bringing quality and value, which is a great thing in the PSU world and not often seen from the big brand names."

Fractal is showing off several new products at Computex, but the one that caught my eye was the new Node 202 which is a small form factor Mini ITX case perfect for the living room. The thin case is all black with a metal texture finish, rounded corners, and diagonal ventilation grilles along the sides and top. The 10.2 liter capacity case measures 377mm x 88mm x 332mm (including case feet) and can accommodate SFX power supplies, Mini ITX motherboards, and a dedicated graphics card.
The front of the case has two USB 3.0 ports and two audio jacks in the bottom left corner next to the power button. Large filtered vents are located on the right, top, and bottom of the case while the left side has a thin grill along the bottom. Needless to say, there is plenty of room for airflow and the case would do well with both air cooled and fanless systems. Users can mount the case horizontally or vertically using an included stand. Interestingly, the Node 202 divides the case into two separate chambers to isolate the graphics card from the CPU, motherboard, and power supply to facilitate cooling.
Internally, the Node 202 has room for a Mini ITX or Thin Mini ITX motherboard with CPU coolers up to 56mm tall, a 130mm SFX power supply, and a dual slot graphics card up to 310mm in length. Users can install up to two 120mm fans in the GPU chamber. Storage support tops out at two 2.5" hard drives or solid state drives (SSDs).
Fractal Design is also offering a version of the Node 202 bundled with its Integra SFX 450W power supply. The 80+ Bronze power supply will come with custom length cables and connectors designed specifically for the Node 202. It is covered by a 3 year warranty.
The PSU-less Node 202 will have a MSRP of $79.99 while the Node 202 with bundled PSU will be $139.99. Both models will be available soon in the US.

The SX700-LPT is a SFX-L (the longer variant of the SFX form-factor) power supply with mighty 700W of power for its size, up 200W from the prior SX500-LG.
The “sneak peak” photo from SilverStone also shows a pair of PCI-E connectors on the PSU, which would be a first for an SFX/SFX-L power supply and permit the use of power hungry cards (or even Crossfire/SLI setups). As for efficiency, the image shows an 80 PLUS Platinum certification, which would also be a first for an SFX/SFX-L PSU. Cable management will be easy for existing SilverStone PSU owners as well as the new SX700-LPT uses SilverStone’s standard cable interface (and this also allows the use of their PP05-E short cable set).
No specifics on price or release just yet, only that the SX700-LPT power supply is coming “later this year”.

Computex may be over but SilverStone had enough new product announcements to last us for a while! Among the many offerings there were a number of highlights, including new enclosures and power supplies. We'll check out a few of the new PSUs here.
The first is a new 1500-watt PSU with a smaller size.
ST1500-GS 1500W 180mm ATX PSU
At 180mm deep the most powerful Strider Gold S-series PSU isn't small, but compared to other 1500-watt options (including SilverStone's ST1500 at 220mm) the shorter depth promises some additional chassis options for a high-power build. The ST1500-GS is fully modular and also features all flat cabling.
New SFX Options!
The smallest PSUs in the SilverStone lineup also have new models, with two new SFX power supplies for mini-ITX builds. The first is a more powerful version of the popular 450-watt ST45SF-G, now in a 600-watt flavor in the SX600-G.
SX600-G SFX PSU
Next we have the SX500-LG, and perhaps more exciting to mini-ITX enthusiasts the new 500-watt option in the SFX lineup features a 120mm fan!
SX500-LG "SFX-L" PSU with 120mm fan
The SX500-LG's 120mm "ultra-quiet" fan adds a bit to the depth of the PSU, which is 130mm compared to the 100mm of the ST45SF-G and SX600-G, and it is classified as an "SFX-L" form factor - with only the length being non-standard for SFX. This new fan implementation should really help reduce some additional load noise from a small high-powered system. Both of the announced additions to the SFX family will also feature all flat cabling this time.
There are new models across all of SilverStone's lineup coming up, so stay tuned. No pricing or availablity just yet, but there's a lot to look forward to from SilverStone this year in the cases and cooling department!

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."

Introduction and Features
SilverStone has a long-standing reputation among PC enthusiasts for providing a full line of high quality enclosures, power supplies, cooling components, and accessories. SilverStone recently updated their original ST45SF small form factor power supply to 80Plus Gold status. The new ST45SF-G is rated for up to 450W and comes with fully modular cables. The SFX form factor is frequently found in Micro ATX Media Center PCs and Home Theater PCs.
SilverStone ST45SF-G 450W PSU
Here is what SilverStone has to say about the ST45SF-G: "After successfully expanding and leading SFF (Small Form Factor) cases and SFX PSU into the DIY market, SilverStone engineers have continued their push for advancement in these categories by releasing a true upgrade-worthy small form factor power supply, the ST45SF-G. Despite being half the size of regular ATX power supply, the ST45SF-G can still produce continuous power output of 450W. Its 80 Plus Gold level efficiency is a great leap from the previous SFX best of 80 Plus Bronze and the full modular cables are also the first of its kind for this form factor. To enable users to easily take advantage of this excellent SFX power supply, an adapter is included to convert the ST45SF-G to mount in any ATX case in addition to ones designed for only SFX. For SFF users and for SilverStone, the ST45SF-G is more than just an upgrade, it is an important milestone for DIY desktop computer users."
SilverStone ST45SF-G Main Features:
• Supports standard SFX form factor and ATX (via included bracket)
• 450W continuous power output at 40°C and rated for 24/7 operation
• 80 PLUS Gold level efficiency (87%~90% efficiency at 20%-100% load)
• 100% Modular cables
• Class-leading single +12V rail with 37A capacity
• Strict ±3% voltage regulation with low ripple & noise
• Silent running 80mm fan (18dBA minimum)
• Single PCI-E 8-pin and dual PCI-E 6-pin connectors
• Universal AC input (90-260 VAC) and Active PFC
