PLATINUM EFFICIENCY, FULLY MODULAR AND VIRTUALLY SILENT

CORSAIR HX series power supplies give you extremely tight voltage regulation, quiet operation, Platinum-certified efficiency, and a fully modular cable set. Built with all Japanese 105°C capacitors, they’re a great choice for high performance PCs where reliability is essential.

QUIET, EFFICIENT OPERATION

80 PLUS Platinum efficiency reduces operating cost and excess heat, and Zero RPM fan mode ensures virtual silence at low and medium loads.

100% JAPANESE 105°C CAPACITORS

Premium internal components ensure solid power delivery and long term reliability.

TEN YEAR WARRANTY

Your guarantee of reliable operation that will last across several system builds.

ZERO RPM FAN MODE

Since the fan doesn’t turn on until it’s needed, you’ll enjoy virtually silent operation at low and medium loads.

POWER IN YOUR HANDS

Toggle single +12V rail or multi +12V rail mode. In the “SINGLE” position, the full output capability of the power supply’s +12V rail is available to any and all connectors, while in the “MULTIPLE” position, each individual connector has Over-Current Protection so no more than 40A of current can be delivered on any given cable.

EASY INSTALLATION

The fully modular DC cables make builds and upgrades easy, with clean, great-looking results.

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!

“Excellent customer care. Friendly, helpful, knowledgeable.”

“When my computer malfunctioned, I sent an email to the team and got a speedy response. We then talked on the phone and I followed their instruction to carefully box up the computer and return it to them. This all went smoothly. They diagnosed the problem, let me know and kept me in the loop. The problem was fixed (new PSU needed) and the system was returned ASAP. An excellent team. I felt like I was in safe hands. Well, my computer was!”
