    I had a Thermaltake 600W power supply for a few years and the fan was giving me some issues. I like the brand and this one was a bit more powerful at a reasonable price. The cabling was good. The dimensions listed in the description are for the box it comes in... not the power supply itself. I checked the manufacturers website before I ordered this one from Amazon. The power supply has the normal dimensions for an ATX format. The unit is fairly quiet and I having been running all day for several days now with no problems. The plugs are all black, not colour coded, but they are clearly labelled. If you have swapped out power supplies before you should have no problems. If this is your first attempt then maybe take some pics with your phone before you pull the old plugs off the motherboard.

    Needed to upgrade the power supply in my PC to accommodate a larger graphics card. For the price, this is an excellent pick, and I appreciate my friend for recommending it. Installation was dead simple with a couple of screws to get it into place in my case, and the connectors included more than I could ever need. No annoying buzz, and it powers my PC just as I expected. This is not modular, which means the cable management is not as easy as it could be, but it's a fair trade-off for a significantly lower price.

    The Thermaltake GF1 750W modular power supply has exceeded my expectations. It’s quiet, efficient, and installation was a breeze thanks to the fully modular cables. My PC runs stable and cool even under load, and I appreciate the zero RPM fan feature for silent operation. Highly recommended for anyone needing a reliable and high-quality PSU!

    First impressions were good. The third-party reviews compelled me to buy this psu for the good value. Performance so far has been good, and the provided cabling is sufficient for my multi-gpu server. The cables aren't going tk win any beauty contests, but not terrible and highly functional. However... even under no load (even without any gpu plugged in, igpu only) it periodically makes very concerning coil whine. It starts as a low raspy grumble and works its way up to a VERY loud whine and then suddenly stops in an instant, as if related to a inductor charge and discharge. But why would the inductor cycle like this under no load? And where is the sudden discharge going? Of the dozens of psu I have used between 2001 and present, this is the first time I've ever observed such a sound coming from psu. It is loud enough to hear in the next room over. It doesn't seem to be related to any fan activity. I don't think this is normal... might need to RMA because something has got to be out of spec.

    Fully modular 750 W power supply does the job for my other AMD system. All the cables were supplied - always make sure to only use the cables supplied with any modular power supply - pin connections on the power supply side are often different from model to model, even by the same manufacturer. The cable quality is excellent, with all wires securely jacketed or bundled. This power supply works great with my AMD B650 MSI motherboard. All voltages are within tolerance.

    I recently upgraded to the Thermaltake GF1 1050W fully modular power supply, and I couldn't be happier with my decision. Right out of the box, the build quality of the cables is impressive; they feel durable and sturdy, which gives me confidence in their performance. The cable length is also excellent, allowing for a clean and tidy setup in my case without any awkward bends.Installation was a breeze. The fully modular design meant I only had to connect the cables I needed, which simplified the process significantly. Everything fit perfectly, and I appreciated how easy it was to route the cables for optimal airflow.While the aesthetics of the power supply aren't particularly eye-catching, this isn't a deal-breaker for me. In my application, performance is key, and the GF1 delivers that in spades. It runs quietly and efficiently, providing stable power for all my components.Overall, I highly recommend the Thermaltake GF1 1050W for anyone looking for a reliable, high-quality power supply that excels in functionality over flashy looks. Five stars all the way!

    No issues with power. The fan controller seems to work fine. However, the bargain basement DC fan bearings went out on mine in less than 1 year. That's pathetic. It really should be user serviceable.The modular cables are adequate.
