QUOTE(pekies @ Dec 12 2008, 12:13 AM) http://www.hardwaresecrets.com/article/668/8wanna see huntkey v-power 550W go KABOOM when loading it with 550W of power? Really shocking. Apparently the perfect wattage output is 60% (330W) of stated 550W load, reaching the efficiency of 80%+. When a load of 80% (440W), the efficiency drops to 70%+. When a 100% load (550W) is applied, it exploded.
"If you follow closely our power supply reviews you know that two models we reviewed from Huntkey Green Star series – 400 W, sold in the US as Dynex 400 W, and 450 W – exploded during our tests. So we decided to get a more “powerful” model, V-Power 550 W, to see if it has the same fate as its sisters. Is V-Power 550 W a good power supply or it is as flawed as the members from the Green Star family? Check it out.
The funny thing is that the manufacturer's website lists both rails at 18 A but the sticker clearly lists one rail at 16 A and the other at 18 A. But, like we already explained, this unit uses exactly the same rectifiers as used on Green Star 400 W and Green Star 450 W from the same manufacturer.
What exploded were the two switching transistors. When the power supply explodes it means that the primary side is under dimensioned. When the secondary side is under dimensioned the power supply dies silently, because when a rectifier burns the short-circuit protection enters immediately in action shutting down the power supply.
So Huntkey should have used more powerful transistors and added a heatsink to the rectifying bridge, plus using rectifiers with higher current limits for the +12 V output."Marketing gimmick. 550W my ass. If u have high end cpu, spend a few hundred bucks more on PC&C or Corsair/OCZ or other brands that uses the same OEM with the brands mentioned. huntkey china reply me as: 这家媒体被竞争者收买 the hardwaresecret asking to do it by one of huntkey competitor, and they are promise to solve this problem very soon. |

QUOTE(celciuz @ Dec 17 2008, 10:32 PM) Meaning that review's result was not correct? @@ Or that Huntkey will make an actual 550W that has above 70% efficiency instead? no idea. maybe the review is true. huntkey china in the process to find out the problem. QUOTE(hilmiangah @ Dec 18 2008, 12:56 AM) if that so can we get a refund or change it to a unit that can actually do what the manufacturer claim??? just now got one forumer come self collect huntkey at my place, he said: dono why everyone kutuk kutuk huntkey, how come want compare RM145 thing with RM3XX , RM4XX things . lolz. the efficiency let me try get a good answer from huntkey china. oh ya. those forumers who have problem of buzzing sound pls return to me so i can exchange one to one with greenstar (even that is v-power, stil can exchange wth greenstar 550watt ) |
