Thermaltake TOUGHPOWER GF1 850w PSU: Unboxing and Closer Look
In keeping with Thermaltake’s Premium branding, the black and grey box can be seen here with a picture of the PSU itself taking up much of the front of the box with a feature list on the right-hand side along with the name and 80PLUS Gold rating.
The rear goes into more detail about the efficiency, smart zero fan, low noise ripple design, strict voltage regulation, and connector and output specifications.
Opening the box, we see the PSU itself covered in foam, ensuring it survives the delivery in one piece. We can also see the GF1 wrapped in a cloth cover on arrival.
Taking a first look at the GF1 850w itself, it has to be said that it’s quite the aesthetic piece. Notice there are plenty of ventilation cutouts on the top, front, rear, and the sides above the labels indicating the GF1 has plenty of airflow throughout, especially when the “smart zero fan” mode is turned on.
On the rear side, we can see the power switch, a cover over the 3-pin plug that explains the second on/off switch, which is the switch for the “smart zero fan.” Turning this on enables a mode where the fan doesn’t turn on until it’s under load—keeping the unit as quiet as possible.
The TOUGHPOWER GF1 850w is a fully-modular PSU, and the input bank is well-designed and clearly labelled here. The back-to-back design allows for easy installation and removal of the cables, even when installed in a case.
The TOUGHPOWER GF1 850w comes with all the cables in a canvas bag. The lid is lined with velcro, so it can be used to store and seal the cables you don’t need safely and securely. The cables themselves are mostly low-profile flat cables and completely black in colour providing more overall aesthetic, reducing clutter and increasing airflow inside the case.
Thermaltake TOUGHPOWER GF1 850w PSU: Performance and Load Testing
Since we don’t currently have access to an ATE load tester, a multimeter is used to show the PSU performance on the +3.3v, +5v, and +12v rails. Although we can’t do complete load tests, we can provide relative information regarding variance and fluctuation of current and ripple on the rails, which is integral and indicative of the quality of a power supply.
To perform the above tests, the components and methodology were as follows:
Intel Core i7-10700K (5.0GHz @ 1.3v)
AORUS Z590 Ultra
ASUS GTX 1060 – Power limit set to maximum (116%)
Klevv Bolt X 16GB 3200MHz DDR4
Voltages will be monitored via a multimeter and the AC power draw will be monitored via a power monitor when drawn from the wall. For the idle test, the system will be simply booted up and let run into Windows 11, and after 5 minutes, the readings will be taken when the power draw has leveled out.
To load the power supply, a combination of Cinebench R23 multi-threaded and Furmark will be run to put as much strain on the power supply as possible. After 10 minutes, the readings will be taken, and to ensure maximum pressure, the CPU is overclocked to 5.0GHz at 1.3v.
ATX and Intel both specify that a fluctuation and variable of 5% is acceptable so to number crunch it means that:
+3.3V = 3.135V-3.465V is acceptable.
+5V = 4.75V-5.25V is acceptable.
+12V = 11.4V – 12.6V is acceptable.
Any readings outside of these figures will be an automatic fail.
|3.3V = 3.324v|
|5V = 5.070v|
|12V = 12.024v|
|3.3V = 3.344v|
|5V = 5.070v|
|12V = 12.096v|
Thermaltake TOUGHPOWER GF1 850w PSU: The Verdict
From our limited testing, the Thermaltake TOUGHPOWER GF1 850W excelled in our load testing.
Its fully modular design is not only pleasing to the eye but removes the need for any additional cables, and what cables you need are flat and all completely black in colour. In keeping with Thermaltake’s premium line of products, no RGB is found on the GF1 at all, which seems to be a conscious choice from them. This choice will either trigger the RGB fan boi or please those that detest it to no end.
The overall aesthetic is excellent, and there are plenty of ventilation cutouts on the top, front, and rear. The sides above the labels indicate the GF1 has plenty of airflow throughout, especially when the “smart zero fan” mode is turned on, keeping the fan off until the GF1 is under load. That being said, it was silent when the fan was on, so I couldn’t even tell it was on!
In summary, the TOUGHPOWER GF1 850w power supply from Thermaltake is an 80PLUS Gold unit that has a beautiful aesthetic, excellent performance, great on-paper specifications, and features that truly make it a Premium product and is undoubtedly worthy of your consideration, especially as at the time of writing, the TOUGHPOWER GF1 is available for between £110-130 which makes this excellent value for money and worthy of our Gold and Editors Choice award!
The GF1 is currently on offer at SCAN UK for £99.98 so grab it while it’s on sale!
