Experience powerhouse reliability and whisper-quiet performance with the Thermaltake Toughpower GX1 GX line. Engineered for modern gaming rigs and productivity workstations, the GX1 SP-700AH2NCG delivers steady, clean power with 80 PLUS Gold efficiency, helping you reduce energy usage without sacrificing performance. This long-lasting unit is built to endure the demands of contemporary CPUs and GPUs, offering reliable voltage regulation, premium components, and a cooling design that stays cool under load. If you’re upgrading an existing build or constructing a new one, the GX1 700W model provides the headroom you need for mid-to-high-end systems, plus the peace of mind that comes with Thermaltake’s reputation for quality and innovation.
- High efficiency for reduced operating costs and cooler system temperatures — The Thermaltake Toughpower GX1 700W is rated 80 PLUS Gold, which translates to less wasted energy as heat and improved overall system stability under peak load. With efficient power delivery, you’ll experience steadier voltage and cooler temperatures during long gaming sessions or intensive workloads, helping components perform at their best while keeping energy bills in check.
- Precise and steady power delivery — The GX1 SP-700AH2NCG is designed for tight voltage regulation, offering near ±3% stability to keep your system’s rails within a narrow tolerance range. This level of precision is particularly valuable for sensitive CPUs and modern GPUs, where voltage transients can affect performance, noise, and longevity. Whether you’re overclocking or simply seeking dependable daily performance, you can rely on clean, stable power to fuel your components.
- Quiet cooling for a calm PC — Equipped with a 120mm Fluid Dynamic Bearing (FDB) fan, the GX1 is tuned to deliver effective airflow with minimal noise. The FDB technology reduces friction and vibration, resulting in smoother, quieter operation even under load. This makes the Toughpower GX1 a strong choice for enthusiasts who want strong cooling without sacrificing a quiet, focused computing environment for gaming, streaming, or workstation tasks.
- Premium build with longevity in mind — Thermaltake shields the GX1 with high-quality components, including Japanese capacitors rated up to 105°C. These components are known for their durability and reliability in harsh operating conditions, contributing to longer life, better thermal performance, and robust power delivery over time. Combined with careful design and high-grade materials, this PSU is built to handle long hours, demanding software, and future hardware upgrades with confidence.

How to Install Thermaltake Toughpower GX1 SP-700AH2NCG Power Supply
- Power down your PC, unplug all cables, and open the case to access the PSU mounting area. Disconnect any existing power supply and remove it from the chassis if you are upgrading.
- Align the GX1 with the case’s PSU mounting points and secure it with the screws provided. Ensure the fan intake has clearance from case panels or drive cages to maximize airflow and minimize noise.
- Attach the appropriate cables to your motherboard, graphics card(s), storage drives, and other components. If the GX1 is modular (depending on the exact model), connect only the cables you need to keep the interior clean and unobstructed for airflow; route cables neatly along the back of the case to avoid interference with fans and components.
- Connect the main 24-pin ATX main power connector to the motherboard and the 8-pin (or 4+4 pin) CPU power connector to the motherboard’s CPU power header. Attach PCIe power cables to your graphics card(s) as required, and connect SATA or Molex power connectors to drives and peripherals.
- Double-check all connections for secure seating and proper routing. Ensure there are no loose connectors and that cables don’t obstruct any fans or airflow paths. Close the case, reconnect the power, and power on to verify successful startup and stable operation.

OK for the price, but overall comfort is avergae
Size: 934-Z, Color: Mustard
Easy to put together, color (mustard) accurate to images, and while I understand this is not a high-end chair, I feel like it still needs to be rated for its quality.
Pros: the seat cushions are fairly comfortable and it rolls well. Adjustable footrest is easy enough and mostly sturdy.
Cons: For a tall office chair, it doesn't go up high enough. I actually had to lower my standing desk to sit at it, which then isn't where I want it when I'm standing now. It's also a bit wobbly. The seat area's attachment to the post isn't as solid as it should be for a tall chair, so while sitting, it does tend to lean/slope forward and wobble side to side. The lumbar support is not adjustable, so I'm not even really sure what it does. And the armrests are not very comfortable to use. Since they are hard plastic, they are just a bit too rigid to rely on for any comfort. They are basically there to hold on to when you're getting out of the chair.

Good Value for a Tall Chair
Size: 934W-Z, Color: White
I have received this chair just today and would like to give my first impressions of it.
Height is super adjustable as well as the foot rest. My desk is very tall (~34 inches vs standard ~29 inches) and does not suit a standard height chair. This chair's height is enough to sit comfortably at mybut also still having adjustment to be even higher.
Lumbar support is a manual adjustment that can be adjusted by sliding the lumbar piece up or down and it seems it can be tiled as well.
No reclining feature or slight backrest tilt adjustment. I'm used to my chairs reclining so it feels a little awkward siting in a flat base and straight backrest. I feel like I'm sitting too forward or leaning forward slightly but is probably something I can get use to.
Easy to put together and feels very sturdy. Plastic parts of chair are made from a really sturdy plastic, like playhouse plastic materials. Wheels roll around carpet easily. Mesh seems to be a strong material, though the mesh feels kind itchy on bare skin.
Overall, I think this is a good chair to get if you're needing a tall chair for a good value and can sacrifice no backrest tilt.

Excellent value for money!
Size: 934W-Z, Color: Black, Size: 934W-Z, Color: Black
I absolutely love this office chair! I needed a chair that could support my standing desk without sacrificing comfort, and this one completely exceeded my expectations. It's incredibly sturdy and durable, well-made, and the height adjustment is super convenient, making it easy to find the perfect fit. Even during long hours of work, the seat is comfortable, and the ergonomic design effectively reduces pressure on my back and legs. I love its clean, modern look—it fits my home office perfectly. Assembly was quick and easy, and for this price, the quality is absolutely fantastic!

Perfect chair!
Size: 934-Z, Color: Blue, Size: 934-Z, Color: Blue
I have an adjustable-height desk (also purchased from Amazon) and needed a drafting chair for those times when my body gets tired of standing. This chair fits the bill and then some! I put it together myself; it took me about an hour, but would take me about half that next time, since now I know what to do (and what NOT to do!). All the parts were there; there are even spare parts (see photo). All the holes were drilled in exactly the right places, too, which isn't always the case when I buy things from Amazon (my standing desk is a great example). The chair fits me; I'm short (5'3.5"), and often the seats of furniture are too deep for me to rest my feet flat on the floor. The depth of the seat on this chair is just a little over 18 inches, and with the adjustable footrest ring, it's perfect. I don't think a tall or heavy person would fit in it, to be honest. But it's perfect for those of us who are vertically challenged. I love that it glides easily on my hardwood floors and that it turns 360 degrees. The chair comes in numerous luscious colors, so take your pick! It is very sturdy, has good lumbar support, and the seat and seat back are very comfortable. And the arms flip up, which was an absolute must when I was shopping for this chair. I got it on sale, too -- $109.00 -- and I'm delighted with this purchase.

Excellent adjustable drafting chair
Size: 934-Z, Color: Blue
Excellent chair design, extremely comfortable and exceptionally easy instructions to follow making for simple assembly. Love the amply wide cushioned seat and ergonomic backrest. The height adjustment feature works perfectly as well as positioning of the foot ring . Having the ability to raise the arms is also a big plus! I highly recommend this product for attractive appearance, comfort features, functionality and operation. Really nice chair!
