  3. Protective PCB coating
  4. 80PLUS Bronze certification
  5. Six year warranty

The TUF Gaming series PSUs bring military-grade components and a smart cooling solution together to create a power platform you can depend on. High-quality capacitors and chokes undergo a range of tests, including extreme temperatures and vibration tests, to ensure they meet rigorous military specifications. An Axial-tech fan with a dual ball fan bearing design offers more longevity than other fan types, increasing the overall lifespan of the product. It’s the perfect PSU to slot into a TUF Gaming rig or any DIY build designed to power through AAA games for years to come

MILITARY−GRADE CERTIFICATION

All critical capacitors and chokes in TUF Gaming PSUs are certified to military-grade specifications, ensuring reliable operation over a wide range of temperatures

DUAL BALL FAN BEARINGS

Exemplary cooling is provided by a 135mm fan spinning on a dual ball bearing setup that will last up to twice as long as a sleeve bearing design.

PROTECTIVE PCB COATING

A protective conformal coating envelops the PCB to protect against short-circuits caused by moisture, dust, and debris.

80 PLUS BRONZE CERTIFICATION

The high-quality components used in TUF Gaming power supplies ensure efficient and reliable operation worthy of an 80 PLUS Bronze Certification. The efficiency also leads to low temperatures within the PSU, facilitating an even quieter acoustic profile for the 135mm Axial-tech fan.

AXIAL−TECH FAN DESIGN

Originally developed for top-end ROG graphics cards, Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure. For TUF Gaming series PSUs, we’ve scaled that design to 135mm so it keeps things cool at low RPMs while producing less noise.

0DB TECHNOLOGY

An onboard controller brings the 135mm fan to a standstill when thermal design power (TDP) is below 30%, letting you enjoy light gaming in relative silence. Above 30% TDP, the fans automatically start up again.

FAQ

  • Do high wattage power supplies cost more to run?

    No - the rated wattage of a power supply refers to the maximum amount of power it can deliver at full load, not how much power it uses. More powerful PSUs will consume around the same amount of power as lower powered power supplies in any given PC system, so your electricity bill will not be higher when using a more powerful power supply!

    The best way to reduce your electricity bill when using your PC is to use a more efficient power supply or make your PC consume less power by removing components which are not needed, such as extra drives and expansion cards, or by choosing a cooler-running processor or graphics card.

  • My brand new power supply doesn’t work! Am I doing something wrong?

    It’s possible that the power supply may be faulty, but here are some simple things to check. Firstly, a power supply will not work if you simply plug it in and flick the switch. The power supply will only turn on if you connect it to a working motherboard and associated items (processor, memory, video card, etc). It is actually the motherboard which tells the power supply when to switch on.

    Secondly (if applicable), check the voltage is set correctly to 115/230 volts depending on what country you are in. Thirdly, if possible it would be good to try the power supply in another PC to see if it works, or try another power supply in your PC to see if that works. You can then tell whether it is the power supply which is faulty or the actual PC itself. If all else fails, please contact us for further support, and/or return details.

  • Why should I buy a whole new PSU when I could just replace the noisy fan in my existing one?

    Virtually all the noise generated by a PC power supply originates from the cooling fan inside it, so simply replacing the fan with a quiet fan may seem an obvious way to go. However, if you are thinking about attempting this operation, please bear the following points in mind:

    1. Your existing power supply will be designed to run with a specific amount of airflow in order to adequately cool the components inside and reducing the airflow may lead to overheating and damage to the power supply and/or PC.
    2. All PC power supplies contain very high voltages and even with the power disconnected, the voltages stored in the capacitors can be easily enough to kill. It is not recommended to take the cover off any PC power supply for this reason unless you are absolutely confident of your own ability. Because of the grave dangers involved, all PC power supplies by law carry a warning label forbidding removal of the power supply case.
    3. There will be no standard PC fan connector inside the power supply to use to connect a replacement fan, and it would probably have to be soldered directly into the PCB inside the power supply, or have a specialist power connector attached. This can be a tricky operation to say the least.

    Please consider the above points very carefully before proceeding with an operation to replace the fan in your existing power supply!

  • What is PFC (Power Factor Correction)?

    If you are interested in being “green” and saving the planet, you might like to read a short explanation of how our power supplies can save energy using Active PFC (Power Factor Correction), not to be confused with Power Conversion Efficiency which is also very good in most of our PSUs. “Power Factor” is a measure of how efficiently electrical power is consumed. Ideally, Power Factor would be 1 (or 100%) and known as unity.

    Unfortunately in the real world, Power Factor is reduced by highly inductive loads down to values of 0.7 (70%) or less. This induction is caused by equipment such as small electric motors, fans, fluorescent lighting ballasts and transformers such as those in PSUs. This is bad news for the electricity generating companies who can impose a surcharge on heavy users if they have a consistently low Power Factor, as more electricity has to be produced to make up the shortfall.

    Power Factor Correction (PFC) is used in some equipment to minimise the inductive component of the electrical current. This helps to reduce the losses in the electrical supply to that equipment. Power Factor Correction capacitors are normally used to reduce induction in an electrical load, which minimises wasted energy and hence improves the efficiency of a company and reduces electricity costs.

    It is not usually practical to reach unity, i.e. Power Factor 1, and it seems that most electricity supply companies accept consumers having a Power Factor as low as 0.94 (94%) without imposing a surcharge. Unfortunately most of the cheap (and not so cheerful) PSUs tend to have a Passive PF as low as 0.75 or 75% which in a large office can lead to a PF surcharge.

    However, the good news is that most of Quiet PC’s PSUs implement a system known as Active PFC which involves some clever electronics. This means that their power factor (PF) can be as high as 0.94 or 94% (at full load), while harmful harmonic frequencies are reduced to well below legal requirements. So by using our products, you can be happy in the knowledge that you are doing your bit to save the planet!

  • How do I know what size of wattage power supply I need?

    The best answer we can give to this question is to go ahead and take an intelligent “guesstimate"! There are no hard and fast rules about what size of power supply any given PC needs as a minimum. Our advice would be that if you are replacing an existing power supply, then consider a new one at least of the same wattage as the old one. In addition, if you wish to build in a “safety margin” to allow for reliable running and possible future upgrades, consider adding 100-200 watts to the rating of your existing unit.

    If you are building a new PC, most customers now buy a power supply rated in the region of 500-800 watts depending primarily on the performance level of their graphics card(s) and number of drives to be installed. But in any event if you are unsure about which power supply would be best for your PC then please do contact us by phone or email and we will be happy to give you a specific recommendation based on your budget.

  • My new PSU came with a 24-pin connector but my motherboard needs 20 pins! Do I need an adaptor cable?

    We receive many customer enquiries about this. In fact, most of the 24-pin compatible power supplies we sell come with special motherboard connectors which can be converted to 20-pins with no additional conversion cables. All you need to do is look carefully at the connector and you will see that the end four pins can be slid off, turning the connector into a 20-pin compatible one (see below) - easy when you know how!

“Very well customer relationships”

“I had had an order from quietpc that they said they will ship of their products in 2 days which they did. But unfortunately product has never reached me due to untracking post. But when I contacted with them about that, they offered me a full refund immediately and when I accepted that they had made the transaction right away.

That is what a great company do.”
