ASUS ROG Thor 850W Platinum PSU Review

ASUS ROG is known for producing excellent products. And today, our ASUS ROG Thor 850W Platinum PSU review will give you just that. 

The ROG Thor 850W Platinum PSU is the very first power supply that’s been offered to us by ASUS. It’s also one of the very few that they’ve ever created. 

But needless to say, we’re extremely curious about what they have in store for us. So, we’re checking out all the essentials about the product here in our ASUS ROG Thor 850W Platinum PSU review.

ASUS ROG Thor 850W Platinum PSU Packaging

Our ROG Thor 850W Platinum PSU came in a typical-looking ASUS ROG box. In front, it’s similar to other ROG-based products like their motherboards, where an image of the product is being displayed. 

Of course, the unit and company’s name is present, as well as the main features of the PSU. We find it interesting that the image of the PSU has a glossy feel to it.

On this area of the box, it’s good to note the Lambda A+ rating mixed with a collection of badges. This specific rating is for noise output from the PSU under loads. 

Flipping the box, the rear exhibits more details about the product. There are a number of images that showcase the PSU’s parts, while information on these are present as well. The company even included a couple of its features which we think is extremely useful. 

Other than these details, you’ll also find a couple of certification, regulatory, and classification logos along the bottom area. 

The box’s flap is where you’ll find the PSU’s specification table. It’s listed together with other details that are written in other languages. This section is also where every inventory control label can be seen.

There isn’t much to see on the sides, other than the name of the PSU written in bold letters. 

What’s Inside the ASUS ROG Thor 850W Platinum PSU Box? 

Looking inside the box, you’ll find two additional packages to separate all the accessories in an organised manner. One box carries the accessories and cables while the other holds the ROG Thor 850W Platinum PSU. 

The PSU is packed well and securely, and that also goes for the accessory box. Speaking of the latter, opening the box reveals semi-opaque bags that carry all the needed accessories of the product.

Other than the ROG Thor 850W Platinum PSU, the package includes a quick start guide, twelve zip ties, plus cable combs. You’ll also find four Velcro straps, four PSU screws, a voucher for Cablemod cables, plus an ROG Eye case badge.

We highly appreciate ASUS for including all the necessary accessories to start using the PSU immediately. So that’s what we did after receiving the package. We set it up, switched it on, then tried it out for our ASUS ROG Thor 850W Platinum PSU review. 

But let’s talk about its performance later on and focus on its design and functions first. 

ASUS ROG Thor 850W Platinum PSU Review – Design and Functionality

The first thing that came to mind when we saw the ROG Thor 850W Platinum PSU was it looked rugged. It sports angular shapes and aggressive edges which aim to attract gamers around. 

With its form and design, the PSU looks built and tough enough to take a beating. This only means that the product will surely last a long time. 

On its side, you can clearly see the ROG logo which looks great combined with the PSU’s external design. And if you compare this 850W model with the 1200W model, it’s a bit smaller in form. Specifically, it measures 160 x 150 x 86mm.

Since it has a more compact form, you can easily fit it into a variety of cases. 

You will see the LED screen on the PSU’s side, and this shows the power used when it’s running. For the modular bay, it’s well-laid out and labelled for easy installation. 

For the other side, you’ll see a connector used for the AURA RGB. There’s also a power button and a button for toggling the semi-passive operation mode. Additionally, a huge fan is concealed behind a mesh of grills found along the top.

Now inside the ASUS ROG Thor 850W Platinum PSU, you’ll notice a Power Logic 135mm fan. And to be specific, it’s a double-ball bearing unit under the PLA-13525-B12M model. 

The Thor units from ROG are based on the Seasonic Prime-Ultra Platinum platform and are designed with extremely high standards. And this is something always to be expected from Seasonic. 

Its OLED screen is a modification made by ASUS which shows the present power draw. The data is sent to the screen and is handled by a microcontroller. In addition, this new platform also allows addressable RGB lights which can be managed through a compatible board. 

There are other changes made and these include the supersized heatsinks and preceding double-ball bearing fan. Having these heatsinks means that ASUS aims to make the product function with lower overall noise. This is always a welcomed feature for such products. 

All heavy power transfers to various parts of the board are sent via the PCB. Only the fan circuits utilise a couple of wires. 

Also, most filtering for this PSU is controlled by polymer capacitors with a couple of electrolytic caps that offer the needed capacity. This is to deal with and handle changes in quick transient loads.

The first section of the transient filter is along the AC receptacle and includes two Y and X caps. It goes along the primary PCB with two Y caps and one X cap. 

A MOV helps protect against surges through the mains grid. The main Japanese Capacitor is 105C – 820uf 400V-rated, while bulk capacitors are from Hitachi.

We love the soldering quality for the PSU, and it’s something expected from the platform.

It’s also important to learn about the PSU’s key features. So, we’re looking into those next in our ASUS ROG Thor 850W Platinum PSU review.
