  • Great Performance, Elegant Aesthetics from ASUS!
Style: ROG Strix (Gold) Size: 750W
Over the course of the last 6 months, I have slowly pieced together components for a new personal gaming PC rig. Between finding stuff through either Amazon or Newegg, waiting for stuff to slowly go on sale or come down close to the MSRP, was like fingernails on a chalkboard. Unfortunately, CoVid-19 has caused a lot of price gouging in various items, especially in the market of PSUs. When Amazon Prime day 2020 finally came around, I was excited to see what various computer components would be available. The last two items on my list were a PSU and RAM, of which the latter I ended up finding a good buy on a 32g RAM kit. However, I wasn't so lucky on finding the exact PSU to fit my needs. Not wanting to wait until Black Friday, I decided to bite the bullet and to find a top tier PSU, even if I had to splurge on it. I have already spent too much time trying to piece together components that I needed to build this computer incase something didn't work right out of the box. Since most of the components in my new gaming PC were from ASUS, this PSU caught my eye. I figured that it would tie into the rest of the components nicely, even though the price was about $30 more than I would have liked to have paid, but was it really worth the $155?? (...this PSU looks so pretty!!) After tossing and turning a few night, and seeing that it was quickly going out of stock, I went ahead and bought this bad boy. On the other hand, not to let you guys think this was an impulse buy, I did some extensive research on this PSU. First off, this particular model won't be found on any current heirarchy chart as ASUS uses another famous and good company that makes really great PSUs: Seasonic. Yup that's right, this uses a modified version of Seasonic's Focus Plus Gold series, which is considered a top end PSU. Secondly, the 10 year warranty was another reason that I knew this was a good buy as well. After waiting four days for this PSU to come in the mail (and practically losing sleep over it cause I was so excited to finally build my computer) I finally couldn't wait to rip the package open to see all what was inside. What I found was: The PSU itself (duh!), a translucent ziplock baggie with some nice magnets to either put on the PSU, PSU shroud or chassis of your PC case, some small stickers to place on the I/O side of the PSU, the installation booklet, some velcro strips, four screws, and in a separate, sleek looking nylon bag, all the cables necessary to hook up your components to your motherboard, including two SATA cables with four headers and a molex cable. The cables themselves are sleeved as a whole (not individually sleeved) in a sturdy, black nylon material and there are no "ketchup and mustard" wires insight. The SATA and the molex cables, however, are the standard flat black cables. These cables are also VERY long, considering that my case is a mid tower ATX case. These could probably easy reach components in a full tower cases using an eATX motherboard without the need for cable extensions. The cables are also very flexible, not stiff like some other PSU brands with flat cables. When I finally got everything hooked up, and turned it on for the first time, it was beautiful. Even though this PSU has a 0 dB button, with it turned off (the fan constantly running) the fan is virtually silent. In the end, I definitely don't feel guilty splurging on purchasing this product. I definitely recommend ASUS PSU to anyone that wants to add elegance and a reliable PSU to their PC build. It may be a little pricer than some of the other PSUs in the same category, but I guarantee you won't regret it! ... show more

  • Solid PSU.
Style: Aura Edition|ATX 3.0|PCIe 5.0 Size: 1200W
I purchased this PSU when I was updating my gaming PC. I wanted something future proof in case I ever went with a power hungry GPU. This one fits the bill at 1200W. Its super quiet and stays very cool. 10 year warranty gives me the piece of mind that this is built pretty solidly. The cable set that it comes with has a textured feel to it that feels high quality, and modularity means that installation is a breeze. There is a subtle RGB accent light on both sides. ... show more

  • Future-Proof Cable Kit – Perfect for PC Builds, Gaming Rigs, and Upgrades!
Style: ROG Strix (Platinum) Size: 1000W
If you’re building a high-performance gaming PC or upgrading your setup, this cable kit is an absolute must-have. The build quality is exceptional — thick, durable, and flexible cables that are easy to route and manage. Every connector clicks in solidly with zero wiggle, which is exactly what you want for a stable, long-term build. What really sets this kit apart is the massive variety of connections. It comes loaded with multiple SATA power cables, support for different GPU types (perfect for both single- and dual-GPU setups), and even extra plugs I didn’t need yet but will keep in reserve for future upgrades. It’s rare to find a kit this versatile and future-proof. The included cable management tools are a game-changer — Velcro straps, zip ties, and labels made it super easy to keep the build clean and organized. And yes, it even comes with a pack of stickers to give your rig that personalized touch. It even had a cool little bag to hold all your bonus cables so you can stash them in “the cable drawer” every adult human for some reason has. Performance-wise, it’s flawless. No power drops, no loose connections, no issues at all — just a rock-solid, clean setup. Whether you’re running a high-end gaming rig, a workstation, or just refreshing an older build, this kit has everything you need in one box. Bottom line: This is a premium-quality, future-ready cable kit at a great price. If you want a clean, organized build with every connection covered, grab this — you won’t regret it. ... show more

  • Super Quiet!
Style: ROG Strix (Platinum) Size: 1000W
Love it, so far very quiet and does what it is supposed to do. Only gripe is the cables, while flexible and woven, need to be wrapped to help with able mgmt. It's like running spaghetti wires everywhere and trying to avoid crossing between them is a pain.

  • Thermal protection, Asus quality, surprisingly affordable
Style: ROG Strix (Platinum) Size: 1200W
This PSU was on sale for 200 dollars during a sale making it one of the best deals for a platinum 1200 watt power supply. I wanted to upgrade to a atx 3.1 psu for my nVidia RTX 5090 and with worries over some 12 pin connectors melting down and destroying the whole system, the thermal protection on this PSU was a major selling point. ... show more
