AsusTek Computer Inc. (ASUS) is one of the older, most influential, and most innovative companies in the enthusiast realm having been founded by former Acer engineers in 1989. Today, ASUS’ product portfolio touches on just about every aspect of the consumer, enthusiast, DIY, and even the professional market with products such as tablets, laptops, desktops, servers, smartphones, networking equipment, motherboards, video cards, disk drives, cases, and so on. Among this huge product portfolio, ASUS maintains its Republic of Gamers marketing which is generally applied to a certain subset of their enthusiast-oriented offerings. ASUS has expanded these items to include power supplies and, today, we are looking at the ROG STRIX 750W (ROG-STRIX-750). This particular unit is produced in conjunction with Seasonic.

Seasonic is one of the older companies producing consumer power supplies having been founded in 1975 and entering the PC power supply production market in 1980. Seasonic is the OEM and ODM of this unit. During that more than 30 years as a company, Seasonic has cultivated lines of power supplies that are today some of the standard-bearers for efficiency and quiet computing. This focus, and its reputation for quality, has lead to an explosion in production as Seasonic can be found providing OEM services on various model lines for Antec, XFX, Corsair, PC Power and Cooling, and of course under its own Seasonic brand.

Tough Enough To Power Your RTX3080/RTX3090?

The ASUS ROG STRIX 750 Watt is the second power supply we have seen from ASUS here at TheFPSReview (the previous being the ASUS ROG THOR 850W). This particular unit is probably going to be a bit more interesting for more people than the last ASUS unit we reviewed as it is a more mainstream product in model/price range. As this product is coming to us at a more reasonable market position from ASUS’, we have fairly high expectations when it comes to performance and value. However, before we get to far ahead of ourselves, let’s first see what ASUS has to say about this unit:

The ROG Strix Series PSUs bring high-end cooling and premium components together for an ultra-quiet high-performance product aimed at core gamers. In terms of cooling, massive ROG heatsinks trickle down from the mighty ROG Thor series and Axial-tech fan design from our premium NVIDIA RTX™ graphics cards also make an appearance. Below the surface, low RDS (on) MOSFETs and premium Japanese capacitors take on power delivery with ease. The result is an incredibly quiet and efficient power supply with the reserves to handle the most intense gaming scenarios.

Let’s move on now and see what we can expect when a user purchases the ROG STRIX 750W power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
