BitFenix’s foray into the depths of the PC space doesn’t stop on audio solutions alone, as the company quickly expands into the other realms of the market. The one I’m talking about are Power Supply Units, a more logical way for BitFenix to explore since it’s the next thing you’d probably think of when you hear the word case or chassis; a field where BitFenix proudly puts itself into the minds of many.

The PSU we are talking about here is the BitFenix Fury 650G; The middle weight of the Fury PSU Family with 650W of capacity. This power supply is designed by BitFenix themselves and is built by FSP. Now FSP Group is a well known OEM in the industry, and BitFenix made the right choice to go in partnership with them. Seriously, it’s a company that builds power supply units for various mission critical conditions such as IPC, and medical usages. Can’t beat that OEM for sure.


Feature wise, BitFenix didn’t just got a reputable PSU OEM and just sell the Fury with their color on the market, as they did include some notable features to distinguish themselves from the saturated the market. First up are the modular NanoSleeve cables, which actually is similar to company’s Alchemy cables from which I adore. The Fury 650G features a maximum of 650W total power output, with an 80 Plus Gold Certification. The BitFenix Fury 650G also comes with an outstanding 5 Year Manufacturer Warranty.

The BitFenix Fury 650G came in a rather large box, similar to the packaging used on higher wattage power supplies. Up front is a very bold image of the PSU itself, with all of itsThree notable features.

The back is busy as usual, with more about its features presented in a graphical manner, along with its specifications, and multilingual feature sets.

The Fury 650G is well packed inside a hard foam inner packaging, while the cables had their compartment. BitFenix really did their homework here as always.

The bundle includes the modular set of cables, a set of mounting screws, a small user’s guide, and a thick power cord. If you want to know the length of the cables and what’s actually included, check out the table below.

ATX 20+4 pin x1 (600mm)
6+2 pin PCIe x4 (600mm)
4+4 pin EPS12V/ATX12V x1 (650mm)
SATA x6 / x4 (600mm + 100mm)
MOLEX x3 (400mm + 150mm + 150mm)
MOLEX x2 (500mm + 150mm)
FDD x1 (+150mm)

The individual NanoSleeve cables look and feels really premium, and conform to the 18AWG industry standards. It terminates using BitFenix’s own design so you can’t actually use most of them on other modular PSUs except from the ones made by FSP such as the AURUM Series of modular PSUs. I have no major gripe about the cables, but they are actually stiffer than the Alchemy cables. That said, for T-connections / extensions such as the one found on the 3x 4-pin MOLEX, you’re going to have a hard time playing with it on tight spaces. I kinda want to see a proper T-connection here similar to those used on other modular flat cables from other PSU makers.

The BitFenix Fury 650G by size is comparable to your standard PSU but is nowhere near when it comes to aesthetics as this one screams with originality from BitFenix. While the design is actually over the top personally speaking, it’s kinda awesome to look at and is very well built actually.

The PSU’s side profile features the specification chart, where things might look boring but it is as interesting as the PSU itself. You see, the BitFenix 650G has 5 Rails, 4 of which are the minor except for the 12v that supplies the power to high current hardwares such as your GFX card provided that it has an external power source. Going back, we could see that the 650G features a high Amperage minor rails rated at 26A for both the +5v and +3.3v rails. This is good, but FSP sacrificed the 12v rail by featuring 50A of power. Still, it’s pretty good considering that even the current flagship cards are sitting below 45A when it comes to recommendations.

Now the BitFenix Fury 650G is rated officially at 650W, but on the specification sheet, it is able to output a maximum of 750W. I have no other means to verify this but the review from KitGuru, where we also sourced the table for the specification sheet, noted that it is able to output a maximum of 689W. SAUCE

DC Output +5V +3.3V +12V -12V +5Vsb
Max Output 26A 26A 50A 0.5A 3.5A
Max Combined Wattage 150W 600W 6W 17.5W

The top side of the Fury 650G features the same design seen from the intake side of the PSU. This keeps the design uniform while enabling you to marvel at the design implementations of BitFenix even if the PSU is in use.

The Fury 650G features 10 power I/O ports. There are 5 for the auxillary, 4 for the graphics adapter, and another one for the CPU. The BitFenix Fury 650G is using the FSP proprietary connectors. Not bad.

As for the internals, please go and check out KitGuru’s review of the Fury 650G. I am not yet acquianted when it comes to PSU components, and it is much better to ask the ones who are actually veterans on the field of PSUs such as the publication mentioned above and JonnyGuru; one of the best source of PSU reviews. I might have already learned somethings but it is better to say the truth. Rest assured if we ever had the chance to play with the proper equipment and we’re confident enough, we will try our best to test PSUs.


The BitFenix Fury 650G is easy to install, and since it’s a semi modular PSU, it’s even easier to route cables and just use what you need. Overall, the build went smoothly and the cleanliness is incomparable to our system using a messier PSU.

The NanoSleeves are not flat, but they are individually sleeved you you could still lay them flat specially on tighter spacers such as the back of a case, or a drive bay.

Now since we have said earlier that testing PSUs requires proper equipment, we still could provide some tests results using our test system and voltage monitoring tools – Albeit they are not that accurate compared to devices made for such tasks. For this test, we will measure the voltage regulation of the PSU with the help of our Z97 Test System and AIDA64’s System Stability Test. The system is left to run with the said tool for 5 hours.

BitFenix Fury 650G Voltage Regulation

As you can see from the chart above, the BitFenix Fury 650G stayed within the safe operating margin for a power supply unit. The +5v is particularly consistent, while the +12v test result is decent. The +3.3v is also not particularly the best but it is not worst either.

In closing, the BitFenix Fury 650G looks like a fundamental step for BitFenix’s insertion into the PSU market, coming with a set of features that will surely make anyone think twice before purchasing any other power supplies in the market. We particularly love the NanoSleeves, the styling, and the cleanliness of our build while using it which is actually the reason why you should consider using a semi or fully modular power supply.

As for the components and performance, we cannot say much, but we’re happy to report that our system is still running fine and stable until this day. But seriously, you should check out other reviews on the web about the 650G – and I mean “reviews” literally, as voltage regulation tests wont cut it alone. You have to check out its ripple tolerance, efficiency, voltage regulation performance across different loads, and even the fans, noise, and temperature.

While I’m no expert in the field of PSUs, I do believe that the BitFenix Fury, together with its set of features and outstanding 5 year warranty, is worth to take a look at. I am not yet recommending this, but if what you have already read here made up your mind, then it is at your discretion to do what you want. Again, if you’re looking for reviews, go ahead and check out KitGuru’s review of the same power supply.
