SilverStone Releases Compact Titanium Certified PSUs

The power supply is one of the parts of your system where you never should cheap out as it’s the backbone of your system that supplies anything with power. SilverStone now released three new models in the Strider Titanium series, the ST60F-TI, ST70F-TI, and ST80F-TI, that not only come with great specs and impressive titanium certification, they are also very compact and fully modular at the same time.

The new Strider power supplies meet the strict 80 PLUS Titanium efficiency rating where they have to stay above 90% efficiency, even at very low load conditions. This is a tricky thing to achieve and that is why we mostly have seen large units with this certification. SilverStone cracked this and are now offering these ratings for the Strider 600W, 700W, and 800W power supply units in a compact size.

The new units are only 150mm deep and at the same time they come with a fully modular cable system. This allows for the usage in any ATX compatible case with ease and it also allows you to make a great cable management. Speaking of cables, the new Strider units come with flat cables that should make the overall cable routing easier. They have better flexibility and allow for tighter folding.

SilverStone’s ST60F-TI, ST70F-TI, and ST80F-TI are built around a single +12B rail design which allows it to deliver the best possible power to all connected components. It has a ±3% regulation and low ripple & noise performance for high stability. The PSUs are built with all Japanese capacitors and rated for 24/7 continuous power output. Overall, some amazing looking power supplies.

These world’s smallest fully modular ATX power supplies with 80 PLUS Titanium efficiency will be available starting next week for an MSRP of $161.70 USD for the ST60F-TI, $178.75 USD for the ST70F-TI and 195.80 USD for the ST80F-TI.

EVGA Announces 700B Value Power Supply

You should always make sure that the power supply in your system is of decent quality, after all, it is the heart of your system that supplies every single part with power. That is a thing that can get tricky when you are building a system on a budget, but still need a large amount of power. EVGA has a power supply for just this scenario with their 700B 700W PSU where performance meets value as they call it.

The 700B name is made up of two things, the 700 watts of power it can deliver continuously and the B comes from its 80 Plus Bronze certification that guarantees over 85% efficiency under typical loads. The power supply is built around a single +12V line supporting 56A. The one thing that might put a dampener on this PSU for some people is the fact that it is completely non-modular which makes it harder to create a proper cable management.

EVGA naturally built in a full set of heavy-duty protections to ensure that nothing gets damaged in unusual situations. The 700B includes Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Power Protection (OPP), Short Circuit Protection (SCP), Over Current Protection (OCP), and Over Temperature Protection (OTP).

EVGA is backing the 700B power supply with a 3-year warranty, but they didn’t announce a pricing at this time.

ENERMAX Released MAXPRO PSU Series

Enermax has a lot of experience in the cooling and power supply market, and the newest MAXPRO series looks to be another stable power supply, designed to last for a long time. The new series will come with 400, 500, 600, and 700 watts to cover most users needs. Due to an adequate number of 8-pin PCI-Express connectors and a massive 12V rail, the MAXPRO ensures a stable power supply of performance-capable gaming PCs. The PSU measures just 14cm in depth, so it’ll also fit into small form factor cases.

Enermax didn’t just want a stable and efficient power supply, they also wanted ultra-quiet operation. Their engineers improved the fan control and also replaced the usual ball bearing fan with their own 12cm fan using Twister Bearings. With just 500 RPM, the new MAXPRO power supplies operate virtually silent at standard loads up to 50%. When peaking over 90% load, the MAXPRO’s fan exceeds 1,500 RPM but doesn’t generate mechanical side noises thanks to the Twister Bearing technology.

Efficiency and safety are two important aspects of a PSU. At a usual system load of 20 to 50%, the power supply achieves an average efficiency of 87% to comply with both EU’s eco-design regulations as well as the international 80 Plus certification. Enermax applied high-quality and performance-capable components which ensure a 24/7 non-stop operation at 40°C. In case of malfunctions or defects, the advanced SafeGuard protects the PSU and the system components against over-current, over-voltage, over-power, short circuit as well as sudden power surges (OCP, OVP, OPP, SCP & SIP) and the unit itself is covered by a 3-year manufacturer warranty.

The new Enermax MAXPRO series is available now apart from the 700W model, that one won’t be ready until the mid of April. The MSRPs are €49.90 for the 400W, €59.90 for 500W, €67.90 for 600W and €79.90 for the 700W model.
