HX Series HX650 Power Supply — 650 Watt 80 PLUS® Gold Certified Modular PSU

Quiet operation at low loads, modular cabling and high efficiency make Professional Series a great choice for high-performance PCs.

HX Series Modular Power Supplies: Legendary Performance and Reliability

Quiet operation at low loads, modular cabling and 80 PLUS® Gold efficiency makes HX Series PSUs a great choice for high-performance PCs.

Quiet operation at low loads

Basic PC power supplies have fans that spin whenever your PC is on – whether you’re pushing your graphics card to the limit or just surfing the web. HX Series power supplies are smarter than that: they generate less heat, so they require less cooling, and the thermally controlled fan only spins when it’s needed.

Slay the cable kraken

The modular cable set allows you to use only the cables you need for your particular set of components. There’s no more unwieldy mythical tentacled monstrosity of unused cables to clutter up the inside of your case.

The modular connection system lets you slay the cable monster.

High efficiency – Low heat

Efficiency is the measurement of how well a power supply converts the AC power from your outlet to the DC power used by your PC’s components. If your power supply isn’t efficient, it will generate more heat, which requires more cooling and more fan noise. And, it might even affect your power bill.
HX Series PSUs are among the most efficient on the market. They help keep your PC cool and quiet, and your power bill down.

Using a AXi Series PSU and Corsair Link's "power" tab with different configurations to determine power usage during different tasks

By Jonny Gerow, on May 31st, 2013

I was curious as to how much power my gaming PC uses with one, two and three graphics cards installed and how that compared to using the integrated graphics of my Intel® Core™ i5 CPU. Corsair Link and my Corsair AX Series Digital ATX PSU helped me determine that! In this blog entry, I show how much power my PC uses with the different configurations.

Right now I have a Core i5-3570K running at 3.4GHz and three Gigabyte GTX670 2GB cards each running at 980MHz.

Currently, I'm just sitting here typing this while listening to music streaming on Pandora. Not a lot going on, so I'm seeing what sums up to a whole lot of nothing going on within Corsair Link. I'm pulling 224.9W from the wall, which is still a lot... but that's primarily because I'm keeping three graphics cards powered even though I'm not using them. Spoiler: We'll see that number lower as I take cards out of the system, even sitting here doing a whole lot of nothing.

Haswell compatibility with Corsair power supplies

By Jonny Gerow, on May 9th, 2013

A report recently published over at the VR-Zone discussing the new 4th generation Intel Core processors, code-named "Haswell", and their ability to go into a lower power sleep state than any previous processor has caused some concern about PSU compatability with the new processor.

When an Intel Core (i3, i5, i7) processor is idle, it goes into a sleep state that requires less power than when the CPU is active. Since the motherboard voltage regulation modules that provide power to the CPU gets their power from the power supply's +12V rail, these sleep states can dramatically reduce the load on the power supply's +12V rail.

Using Corsair Link to Monitor a Corsair AX860i Digital ATX PSU's Power Output, Temperature, and Fan Speed

By Jonny Gerow, on April 11th, 2013

Many Corsair power supplies feature cooling fans with Zero RPM technology. Essentially, while the power supply is at lower loads and producing less heat, the intake fan is stopped, therefore producing zero noise. As the load on the PSU increases, the power supply produces more heat and that heat needs to be evacuated. A thermistor inside the power supply tells the fan to kick on. Once those temperatures drop to a level that is safe for the power supply to operate without active cooling, the fan cuts off and the power supply runs silently once again.

For my demonstration, I will be using an AX Series AX860i Digital ATX PSU and Corsair Link software to demonstrate how the PSU's power output and temperatures increase with load, and how the power supply fan speed increases and decreases with that temperature.

Why does a better power supply mean a better computing experience?

By Jonny Gerow, on March 13th, 2013

So how does a better PSU equate to a better computing experience? Consider this: If your power supply isn't doing a good job of regulating voltage and filtering ripple, what is?

The computer power supply essentially converts AC to DC. Older or more basic computer power supplies convert AC to multiple DC voltages (+12V, +5V, +3.3V) at the same time. Newer, more advanced power supplies, convert AC to +12VDC, while smaller DC to DC power supplies within the power supply's housing convert the +12V to lesser used +3.3V and +5V. The latter is more efficient because lesser used voltages are not converted unless they're required and converting DC to DC itself is more efficient than converting AC to DC as it requires fewer and smaller components.

After that voltage is converted, it's filtered with inductors and capacitors.
