Seasonic FOCUSes on quality in their new SGX PSU

Subject: Cases and Cooling | March 11, 2019 - 03:04 PM |
Tagged: FOCUS SGX, seasonic, modular psu, 80 Plus Gold, 650W

Given its small size, having four PCIe connectors, six SATA connectors, and three Molex connectors on the Seasonic FOCUS SGX is no mean feat.  That will give almost any SFF build more than enough power, or even a full sized build if you prefer a small PSU for whatever reason.  The 10 year warranty indicates Seasonic has a lot of faith in this unit, and [H]ard|OCP's testing shows it is deserved.  You will pay a little more for the FOCUS SGX but in this case it is actually worth it.

"Seasonic is FOCUSing more on small footprint high output power supplies, and the new FOCUS SGX series is targeting the small form factor market once again. This beefy 650 watt unit is fully modular, packs a 10 year warranty, is diminutive in size, had good efficiency, and comes complete with an ATX adapter plate as well."

SilverStone Reaches 700W in the SFX PSU Form Factor with the SX700-G

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.

The SX700-G includes SilverStone's flat cable design for easier cable routing and enough power cables to connect up to two GPUs and six SATA drives. It is launching with an MSRP of US$155.99 and should reach retailers in North America by mid-December. Check out the complete list of specifications below.

Seasonic's Focus Plus series shows Gold can be better than Platinum

Tagged: seasonic, FOCUS PLUS, 550W, modular psu, 80 Plus Gold

Seasonic have added a 550W PSU to their Focus Plus lineup of petite PSUs.  Measuring a mere 5.5" in length it uses a 120mm fluid bearing fan for cooling and is completely modular.  Inside you will find Nippon Chemi-con components which may account for why this unit outperformed similar ones on [H]ard|OCP's test bench.  Even better news is the price, running around $80 including shipping, which makes this PSU a solid choice for system which doesn't require an obnoxious amount of power.

"Small computer power supplies that are entirely modular are the cornerstone of Seasonic's Focus Plus series. We are reviewing the Gold variant today rated at 550 watts that has a modern design and with hybrid silent fan control with a fluid dynamic bearing fan. Is the smallest PSU in the Focus Plus series making the cut?"

Earlier this year we looked at the BitFenix Whisper M 850W power supply and today we are taking a detailed look at the BitFenix Formula Gold 750W unit. With a lower price point the Formula Gold Series is targeted towards mainstream consumers. The most obvious difference between these two units is the Formula God Series has all fixed cables while the Whisper M Series comes with modular cables. The Formula Gold power supplies use a 120mm cooling fan that spins all the time while the Whisper M units incorporate a 135mm fan with semi-fanless operation. And last but not least is a difference in warranty period. The Formula Gold Series are backed with a 5-year warranty while the Whisper M units come with a 7-year warranty.
