Introduction

Corsair is a well-respected name in the PC industry and they continue to offer a complete line of products for enthusiasts, gamers, and professionals alike.  Today we are taking a detailed look at Corsair’s latest flagship power supply, the AX1600i Digital ATX power supply unit. This is the most technologically advanced power supply we have reviewed to date. Over time, we often grow numb to marketing terms like “most technologically advanced”, “state-of-the-art”, “ultra-stable”, “super-high efficiency”, etc., but in the case of the AX1600i Digital PSU, we have seen these claims come to life before our eyes.

1,600 Watts: 133.3 Amps on the +12V outputs!

The AX1600i Digital power supply is capable of delivering up to 1,600 watts of continuous DC power (133.3 Amps on the +12V rails) and is 80 Plus Titanium certified for super-high efficiency. If that’s not impressive enough, the PSU can do it while operating on 115 VAC mains and with an ambient temperature up to 50°C (internal case temperature). This beast was made for multiple power-hungry graphic adapters and overclocked CPUs.

The AX1600i is a digital power supply, which provides two distinct advantages. First, it incorporates Digital Signal Processing (DSP) on both the primary and secondary sides, which allows the PSU to deliver extremely tight voltage regulation over a wide range of loads. And second, the AX1600i features the digital Corsair Link, which enables the PSU to be connected to the PC’s motherboard (via USB) for real-time monitoring (efficiency, voltage regulation, and power usage) and control (over-current protection and fan speed profiles).

Quiet operation with a semi-fanless mode (zero-rpm fan mode up to ~40% load) might not be at the top of your feature list when shopping for a 1,600 watt PSU, but the AX1600i is up to the challenge.

Tagged: enermax, MaxTytan, 800w, modular psu, SLEEMAX, 80 Plus Titanium

Enermax have launched a new family of PSUs called MaxTytan, with the 800W model appearing for review on [H]ard|OCP.  These PSUs feature Sleemax cabling, each wire is covered in fabric which does look nice but adds bulk to the wires.  The cables plus the 80 PLUS Titanium rating add to the price, the MSRP is $200.  That hurts the rating [H] provided as the power quality they saw in testing was good, but not great, and is somewhat more expensive than the competition.  Drop by for the review, as the PSU provides decent power and a nice look for cases that expose components.

1509316810810acboj02_3_1_l.jpg

"Enermax pulls out a flagship with its MaxTytan PSU, this one rated at 800 watts. The MaxTytan PSU has some interesting features like its on-demand Dust Free Rotation fan system. It also comes with very "custom" looking SLEEMAX cable covers that wrap every single cable individually like you find in custom rigs. And huge Titanium efficiency!"

We are going to kick-off the New Year on a high-note by taking another look at Seasonic’s PRIME Titanium series power supplies. When we first tested the new PRIME 750W Titanium PSU last summer, we concluded it was the best overall PC power supply we had reviewed to date. So was that just a fluke? Did we get a hand-picked power supply? Or did our review sample truly represent the outstanding performance that a regular user would experience after buying one of the Seasonic PRIME Titanium series power supplies through normal retail channels? Today, we are going to test two more PRIME Titanium PSUs and compare our findings with the original PRIME 750W Titanium power supply test results. This will provide a unique opportunity to compare three different power supplies from the same series to see how consistent their performance really is, which can be a good indicator of quality.

Sea Sonic Electronics Co., Ltd has been designing and building PC power supplies since 1981 and they are one of the most highly respected manufacturers in the world. Not only do they market power supplies under their own Seasonic name but they are the OEM for numerous big name brands.

Seasonic’s new PRIME lineup was introduced earlier this year with the Titanium Series, which currently includes three models: 850W, 750W, and 650W (with more to follow). Additional PRIME models with both Platinum and Gold efficiency certifications are also making their way into retail channels with models ranging from 850W up to 1200W.

3a-Prime-diag.jpg

The two new power supplies we have in for review are the PRIME 650W and 850W Titanium models. These units also come with all modular cables and are certified to comply with the 80 Plus Titanium efficiency criteria; the highest available. The power supplies are designed to deliver extremely tight voltage regulation on the three primary rails (+3.3V, +5V and +12V) and they provide superior AC ripple and noise suppression with an extended hold-up time. Add in a super-quiet 135mm cooling fan with a Fluid Dynamic Bearing and a 10-year warranty, and you have the makings for an outstanding power supply.

The new SilverStone Strider, a 600W 80 PLUS Titanium certified PSU

Subject: Cases and Cooling | November 14, 2016 - 03:32 PM |
Tagged: modular psu, 80 Plus Titanium, Silverstone, strider 600W, 600W PSU

The industries current focus on energy efficiency has made the need for a kilowatt class PSU much less prevalent than a few years back.  With current generation components even multi GPU systems can function with a 600W PSU which is why we are seeing so many arriving on the market.  This has created a challenge for PSU manufacturers as in order to receive an 80 PLUS certification the PSU must be over 80% efficient even at 10% power draw, over 90% for some of the higher ratings.  The Silverstone Strider Titanium 600W PSU came close to meeting those standards in [H]ard|OCP's tests, with some issues in their worst case scenario testing.  The PSU also runs about $140 which is somewhat higher than the competition.  The news is not all bad, check out their findings in full right here.

"SilverStone has been on a fairly successful ride with its Strider series of computer power supplies. These units tout excellent efficiency levels all while packing this into an unusually tiny footprint perfect for small form factor system builds. The ST60F-TI brings with it a solid build quality, near silent operation, all while being fully modular."
