A quick google of Huntkey, brings up enough people talking about their power supplies exploding, further research seems to point to the green star series all failing when attempting to pull the labled load.
Check out the review here
"From the exchange of e-mails with Huntkey and a series of events that happened we learned that this company is far from being honest, besides the fact that they lie about the maximum power their power supplies can deliver:
* 1. After posting the Green Star 450 W review they offered us money to take the review down (
this is documented here). We don’t need to say more.
* 2. Then when we first posted the Green Star 550 W review (that we wrongly posted as being a V-Power 550 W unit) they sent us an e-mail saying that the review was wrong, that we reviewed the wrong power supply (they were correct). They also implied that we were doing this on purpose (as if) and that we got a counterfeit product (as if someone would counterfeit bad products). They also said that Green Star 550 W and V-Power 550 W are different products (which is a big fat lie, as we will expose). In response to our review they posted a video on YouTube showing that V-Power 550 W works well.
* 3. They started a pressure campaign asking all people that know us (especially other manufacturers) to ask us to remove the reviews. Luckily all people they contacted are very professional and told them to take a hike (especially after seeing the videos with the power supplies exploding)."
That just so happens to be the first link I clicked, the first of many mentioning the PSU's exploding. I personally wont bother to go read much more about Huntkey. My Corsair TX650 is the doing its job very well and as advertised.
In my personal opinion, I cant ignore a bad rep like that when it comes to products Im going to pay a lot of money for...
