Thermaltake Toughpower GF1 750W (2024) Power Supply Review

Here's my review of the Thermaltake Toughpower GF1 750W power supply. The 2024 version specifically. 

I needed a PSU for my latest build, and the specs on this one looked alright given what was available on Amazon around Black Friday 2024. It was an abrupt purchase and in retrospect I should have done more research. 

It's an 80+ Gold rated, fully modular unit with a 10-year warranty. On the box it says efficiency up to 90%. But, as I quickly discovered, there's more to this power supply than meets the eye, and not all of it is good.

Look for the Thermaltake Toughpower GF1 750W 2024 version of the PSU through my links:

Thermaltake Toughpower GF1 750W (2024)


First Impressions

The GF1 arrived in a nice, large box.

Thermaltake used really nice dense foam inside the box to protect the power supply. No complaints about the packaging.

The 10-year warranty is reassuring, assuming Thermaltake fully supports their warranties, and this unit has been working fine so far.


Size and Design:

The dimensions of the GF1 are 150mm x 86mm x 140mm.

Dimensions

It's a pretty standard size that should fit most cases. In my build, there's just barely enough space to fit a fan on the bottom, but that's more about my case choice than the PSU.

PSU fully modular design.

The fully modular design is a huge plus. You only connect the cables you need, which keeps things tidy and improves airflow. Though, I wish Thermaltake would have split some of them into more cables so there were fewer connections per chain. 

Extra bag included to hold cables.

It even comes with a nice bag to store the unused cables.

Key Specifications:

  • Output Capacity: 750W
  • Efficiency Rating: 80+ Gold (Up To 90% as it indicates on the box).
  • Cooling: 120mm hydraulic bearing fan with a "Zero Fan" mode.
  • Zero Fan Mode is available from 0 to 30% load.
  • Cables: Flat, black, fully modular.

Specifications.


The 750W capacity is more than enough for the build (RTX 4060 and AMD 9900x). I always like to have some headroom. 

Zero Fan mode

The hydraulic bearing fan has been quiet. I haven't even bothered with the Zero Fan mode (activated by a switch on the back), because the normal operation it seems quiet compared to everything else in the computer. 

Side ventilation

The Cables: Flat and Functional (Mostly)

The flat, black cables are definitely easier to manage than the old style of bulky round un-sleeved ones.

Flat style cables

They also have a bit of "memory" to them, meaning they tend to stay where you bend them. This was helpful when routing the CPU power cables around my top-mounted fan.

Cables included listing

The following cables are included:

  • Main power connector (24 pin)
  • The ATX 12v (4+4 pin)
  • PCI-e (6+2 pin) connectors (four connectors total over two cables)
  • SATA Connectors (8 total over two cables)
  • 4 Pin Molex Connectors (four total, over one cable)


The Downsides: Where Things Get Confusing

This PSU doesn't have the 12VHPWR connector. It wouldn't make much sense to include that considering those can go up to 600W.

The CPU power connectors, in particular, were a bit of a pain to route. They were difficult to orientate on my MSI x670e gaming plus Wi-Fi motherboard and Fractal Focus G case.

CPU power was difficult to connect but that depends on your other components and case.

I wish the cables were a bit longer, or that there were two separate CPU power cables instead of a single, daisy-chained one. It worked out, but it was tighter than I'd like.

Overall cable selection is a bit limited and daisy chained. If you have a ton of those four pin Molex connectors you might be somewhat limited.


The Main Problem: Two PSUs with the same name.

There are two versions of the Thermaltake Toughpower GF1 750W. Mine is the 2024 version, but there's an older model with almost the same name. They're both labeled "Premium," but the model numbers have a subtle difference: one ends in "1," the other in "P".

Two different PSU versions.

They are significantly different.

Size: The older version is 160mm long, while mine is 140mm. That's a big deal for smaller cases.

Fan: The older one has a 140mm fan, mine has a 120mm fan. The Amazon listing for the new version incorrectly states it has a 140mm fan.

Capacitors: One of them say premium Japanese capacitors and the one I have has "high quality" main capacitors.


Connections: They have a difference in their layout.

Difference of modular connections.

Peak Output Capacity: The old version is 900W and it's not mentioned on the newer one.

Voltage Regulation: Strict voltage regulation is only mentioned on the older one.

Some of the specification differences.

Thermaltake, why would you use essentially the same name for two very different products? It feels incredibly misleading, almost like a bait-and-switch. I was rushing to buy components during Black Friday, and I didn't notice the subtle differences. 


Differences I've found between the PS-TPD-0750FNFAGU-1 (TTP-750AH3FCG) and PS-TPD-0750FNFAGU-P (TPD-750AH2FLG): 


Should You Buy It?

It seems decent. It functions. It is doing everything that I need it to do. I have put on maybe 300W or 400W max on the PSU. The fan is very quiet. It's generally a functional power supply, so why did they bother using the same name? 

The PSU.

The Thermaltake Toughpower GF1 750W (2024) works. My computer is stable, and the fan is quiet. But the naming confusion and the discrepancies between the two versions leave a bad taste in my mouth. 

Thermaltake needs to be more transparent and consistent with their product naming. Do your research carefully before you buy any power supply, and double-check those model numbers!

Upgrading from GTX 1060 to RTX 4060: Performance Gains in an Older System

(I used Claude AI to generate this article based on my video's transcript, so keep that in mind it might not be perfect even though I've gone through it to correct any issues I see. Also keep in mind that I've done further testing with an ASUS Proart 4060 compared to the MSI 1060 on my old PC and noticed a few situations where the CPU was limiting performance such as FFXIV minimum framerates.) https://youtu.be/yR6XPvt-F0A Check out the GIGABYTE 4060 OC Low Profile 8G card:  Amazon: https://amzn.to/3IMz7vb   B&H: https://bhpho.to/4970evV   Or look for a used MSI 1060 6GB ARMOR 6G OC OCV1 card:  Amazon: https://amzn.to/43oY9Kt ebay: https://ebay.us/3IqNQg   As an affiliate of these shops, I earn from qualifying purchases!  I recently decided to take a look at the GIGABYTE RTX 4060 low profile version.

Working on a second GPU review.

 I might as well start things off here!  I'm working on a second GPU video because I had ended up swapping out the cheap Amazon Warehouse Deals RTX 4060 one for a larger quieter one. I also was able to do 4k tests without a 4k monitor by using the Atomos Ninja V. Starting to look through the results. Here is one in Google Sheets on Affinity Photo 2 using their built-in benchmark.  The ASUS Proart RTX 4060 has a performance and quiet mode which is what the PM and SM data lines mean. So far from what I've seen of the data these two modes don't mean much from a performance standpoint, at least on my old i7-6700 based PC build. It feels like a marketing based feature and I'm probably going to leave the card in quiet mode.  I'm not sure how much of a difference these scores mean in practice between the GTX 1060 and RTX 4060, but the number is larger! haha

Comment on the TikTok ban from a technology perspective.

See the latest news here:  https://apnews.com/article/tiktok-ban-trump-executive-order-1e95d9836bf6f8c0c245ed1c3234d968  The AP article saying Biden will not take action in his term. Finally a bit of common sense. What good is a country that censors what citizens see? Doesn't one side claim to be a bastion of freedom? It goes both ways. Let's see how it plays out. Starting to feel like more of a "we can't lose big tech" or "we don't want to lose our political positions" than anything else. 🤷  If there were real security concerns, then our government should work with Alphabet (Google) and Apple to have their mobile operating systems prevent various forms of information from being gathered and transferred through *all* apps on their platforms.  I'll be talking about Android because I have pretty much no experience using Apple devices.  Ever have an Android app literally harass you asking to share your contacts?
