SFX PSUs are great for small form factor builds, at 4" long it will fit into those smaller systems and in the case of this SF450 from Corsair, the 17" long cables allow you to cleanly route them through the chassis.  This is an updated model, you can find the previously released SF450 still on the market and unfortunately for the 2018 model, it is about $30 cheaper. 

Is there anything to the updated model which justifies the increase in price? Check out [H]ard|OCP's full review for the answer.

"The Corsair SF450 SFX is, as you might have guessed from the "SFX" part number, a computer PSU built specifically with small form factor systems in mind. Corsair promises high power density along with "low noise," which are two qualities that many SFF builders are likely looking for. It also brings has Platinum level efficiency and is fully modular."

Everyone loves small form factor PCs these days, but there aren't many SFX power supply options that can keep up with the demands of increasingly powerful CPUs and GPUs. A number of companies have been able to hit 600 watts, and SilverStone was able to reach 800 watts, but only via its "SFX-L" form factor, which is slightly larger than the official SFX specification and therefore doesn't fit in all situations or case configurations.

silverstone-sx700-g-1.jpg

But SilverStone is back with the first true SFX PSU that hits 700 watts. The SilverStone SX700-G is an 80 PLUS Gold-rated power supply with a fully modular design, single +12V rail, and a 92mm fluid dynamic bearing (FDB) fan tuned for silent operation at low loads.

EVGA Launches SuperNOVA GM SFX Power Supplies

Subject: Cases and Cooling | October 4, 2018 - 11:27 PM |
Tagged: evga, EVGA SuperNOVA, SFX, SFX PSU, SFF

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.

EVGA SuperNOVA GM SFX PSU.jpg

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.

BitFenix Releases the Portal: A Sleek Mini-ITX Enclosure

Subject: Cases and Cooling | March 16, 2017 - 09:34 AM |
Tagged: small form factor, SFX, SFF, Portal, mini-itx, enclosure, case, bitfenix, aluminum

BitFenix has announced the Portal, which is one of the more interesting-looking chassis designs to hit the market in recent memory. Available in both black and white, and with or without a top-mounted window to show off your GPU (thanks to the inverted motherboard layout), the Portal is a sleek mini-ITX enclosure with a smooth, rounded aluminum exterior that is certainly a departure from typical case designs.

portal-masterimage.jpg

One of the design concepts made possible by SFX power supplies is a slimming down of the standard tower concept, which leaving component layout identical. In the case of this mini-ITX mini tower case from BitFenix, you might at first think you are looking at a larger case, but that PSU opening is in fact SFX, and the case is just wide enough to accommodate a standard PCIe graphics card.

portal_ww2.jpg

A smaller mini-ITX case is often more challenging to work in, but here BitFenix has a clever solution with their dual-frame design:

"Designed for ITX Motherboards, the striking key component of the interior is the Dual Frame Design for easy access and quick installation. The inner chamber, equipped with enough space for high-end components, slides into the housing via a ball bearing runner design."

portal_bw2.jpg

The external housing slimply slides off to reveal a standard chassis frame, allowing for easy component installation. Beyond the requirements of mini-ITX motherboard and SFX power supply, the Portal allows for CPU coolers of up to 125 mm, and full size graphics cards up to 300 mm long.

Specifications:

  • Chassis Type: ITX Chassis
  • Colors: Black | White
  • Materials: Aluminum | SECC Steel | ABS | Transparent acrylic
  • Motherboard: Mini-ITX
  • CPU Cooler: Up to 125mm height
  • Graphic Card Length: Up to 300mm
  • Power Supply: SFX Form Factor
  • Storage Capacity: 3.5" HDD x2, 2.5" HDD 1+2
  • Cooling Capacity: Front 120mm x1 (included), rear 80mm x1 (included)
  • Radiator Capacity: (Front) Up to 120mm x1
  • Front I/O ports: USB 3.0 x2 | HD Audio Mic & Headphone
  • Dimensions (with stand): (WxHxD) 247 x 395 x 411 mm (9.72 x 15.55 x 16.18 inches)
  • Weight: 5.81 kg (12.81 lbs)

portal_bw1.jpg

Cooling is another area that has received BitFenix's attention, as they have implemented what they call their "intelligent cooling solution" with the Portal:

"To cool the built-in hardware, the portal is equipped with air inlets at all four corners and the bottom of the housing. The air-permeable inner chamber is further equipped with included 120mm intake and 80mm exhaust fan, for a stable airflow for basic Office and Home Theater PCs."

The BitFenix Portal is available now for $139.99 with your choice of color and window option (product pages already up on Newegg.com).

SilverStone has been busy this year expanding their power supply lineup. With a continued focus on smaller physical size and support for enthusiasts in the small form factor arena, SilverStone now offers seven power supplies in the SFX Series, ranging in output capacity from 300W to 700W. Earlier this year we looked at the SX700-LPT, which sits at high end of the SFX Series. In this review we are going to look at the two entry level models, the new ST30SF (V2.0) and the ST45SF (V3.0).

Both of the SilverStone SFX power supplies were designed for mainstream use in small form factor cases but they can also be used in place of a standard ATX power supply (in small enclosures) with the included adapter bracket. As entry level units they forgo some features like modular cables, Platinum or Gold efficiency certification, and fan-less operation. However, in addition to their compact size, the ST30SF and ST45SF incorporate a quiet 92mm fan (instead of the 80mm fans used in previous models), fixed cables, and come with 80 Plus Bronze efficiency certification.

3-Two-PSUs.jpg

SilverStone ST30SF & ST45SF PSU Key Features:

•    Small Form Factor (SFX) design (63x125x100mm HxWxD)
