Huntkey X7 900W Power Supply Unit: Modular Design Inside And Out

littlelion | 25 August, 2009 13:36

A couple of months back at Computex, Huntkey introduced their three new lines of power supply units (PSUs), namely the X7 series, Balance King series, and Pop Power series. Among the aforementioned, the X7 series is visibly intended for advanced desktop users, with models having a minimum output power rated at 800W. There is also the 900W model, which we picked as the subject matter of our feature today.
 
 
 
Similar to the enthusiast-grade PSUs that we had met before, the packaging of the Huntkey X7 900W PSU is relatively substantial.
 
 
 
 Because it is classified as a modular PSU, it comes with a set of detachable, color-coded cables. The modular design eliminates the clutter caused by unused cables. Less mess means users can move more freely as they play around inside their rig’s casing or overclocking bench.
 
 
Among the cables, the ATX 20 + 4 main power connector is the only one that is soldered straight to the PSU. The rest are detachable and measure more or less 450mm long. Here is the rundown of them:
 
 
 3x 6-pin power connectors for SATA and IDE storage drives
 
 
 
 3x 8-pin, 1x 6-pin power connectors for PCI-Express graphics cards
 
 
 
 2x 6-pin power connectors for PCI-Express graphics cards, 1x 8-pin P4 power connector for the processor
 
 
 
 At first sight, the Huntkey X7 900W PSU seems no different from the last Huntkey PSU that we saw in April. If you noticed some disparities, those could be the air vent’s design as well as the power switch’s absence near the power cable socket.
 
 
 
 Huntkey has ensured that users would never get confused while hooking up the cables to the PSU. Aside from the color codes, there are labels as well.

 Heat is actively dispersed from the PSU by its 140mm fan, which is manufactured by the Taiwan-based Yate Loon Electronics. The said company serves also as a source of cooling solutions for other computer manufacturers, some of which are Huntkey’s competitors.
 
 
 
Unlike in generic types, the fan in this Huntkey is not soldered straight to the PCB of the PSU. This photo illustrates that the fan is potentially a customer-replaceable part. Nonetheless, replacing the fan should not be your concern if it is working, the PSU is still under Huntkey’s two-year warranty program, or you are not techie enough to troubleshoot. Be cautioned of the danger of disassembling a used power supply, since some of its internal components, especially the capacitors, can retain electricity for hours or days even after the system has been powered down.
 
 
 
Passive cooling is handled by a pair of heatsinks. The heatsinks also operate as dividers to separate the primary stage from the secondary stage of the PSU circuitry. However, the heatsinks here are not as sizeable as those that we found within other brands and models in the same output power rating.
 
 
 
Adjacent to the longer heatsink is the primary stage of the power supply in which two big electrolytic capacitors from the voltage doubler are located. Next to it is a pair of ferrite coils for transient filtering that prevents possible interferences on other electronic equipments.
 
 
 
 Sandwiched between the two heatsinks are the transformers which are commonly painted yellow. The bigger one is the primary transformer.
 
 
 
Whereas the smaller secondary transformer is partially obscured by ferrite coils.
 
 
 
The secondary stage accommodates the smaller, electrolytic capacitors and ferrite coils of the PSU. Since this is the region where the cables of the main power connector originate, it is comprehensibly cramped.
 
 
 
The Huntkey X7 900W has earned 80 PLUS Silver compliance certificate. Click the photo to see more details of the certification.
 
 
 
Amid the horde of PSUs, both branded and generic, that are on offer in the market today, the Huntkey X7 900W PSU is a promising proposition to consider. The 900W output power and modular design are just good starters. Within, it takes in a design intended to withstand heat and interferences to provide advanced rigs with a stable supply of power. Plus, it is energy efficient and covered by two-year warranty, capped with fairly reasonable price of PhP 9,000.

Is there anyone here who really uses a 900W power supply? I think that P9k is too much.

Comment Icon For overclocking freaks...

overclock a core i7 processor and put in 3 nvidia gtx series cards...with 16 gb ddr3 ram overclocked to 1666, 1 tb hdd, blue ray drive.. liquid cooling with gigantic exhaust fans. this is what you need for that.. but what do you need it for??? you're just wasting money on this. 600w is more than enough for an average gamer.

kristian's comment simply explains why a 900w psu like this is too expensive - the demand is quite low.

Hi, I'm quite new in building rigs. What's the relevance of having a branded PSU? I have a 500W generic one and it still working for almost three years.
