If we want to spoil competitor's brands, we don't need to use words, there are many ways to do it. On the contrary, one of those two whom you mentioned has tried a futile method in damaging our brands but instead killing their own, pretty hilarious actually. Consumers are not as stupid these days. They know how to read reviews and make decision based on that and also on pricing.

Rosewill OEMs from Superflower, Sirfa, HiPower. Rosewill itself is not as popular as Seasonic and will never get better pricing than factory-direct-sale brands anyway.

Bro,
Thanks for the clarification.
I'm a curious person, may i know

1. How they try tried a futile method in damaging your brands but instead killing their own?
2. You Parallel Import their products is to damaging their brand back, revenge??

Thanks

If you are curious to know, why not call our boss yourself to ask about it? Clearly someone is telling you stories, we can put on our story telling hat also but this is not a forum for conspiracy theories or to satisfy your curiosity. It's clearly for PSU recommendation and PSU related discussion.

Bro,

Why are you so angry??? 
I'm asking those question because i want to buy a PSU from u, i need to clear all my doubt before i proceed to buy a PSU from you. 
Since you are the owner of the company and i think you are the  most suitable person to answer my question. 

Just curious, no offense.

Er guys, wondering is it save to pick up a one years old FPS Hexa 500w PSU to power a rig with i5-2500 plus HD 7770? Kinda tight in budget.

Is it true PSU efficiency shrunk every year of usage?

As long as the seller provides reasonable amount of time of personal warranty or receipt then should be ok.
A new one only cost around RM149.
Yup, PSU degrades little by little. If it has better quality components built then would be slower in degrade.

Awesome thx bro, wanna get it from friend for rm50 lol, how many year warranty does new FSP Hexa covered?

Can someone recommend me a cheap and reliable modular psu. Around RM 300 ?

Seasonic M12 II 620W RM329 kalo tak silap..

assuming all other hardwares are same. will upgrading to a higher wattage but more efficient psu consume more electricity?

eg from a bronze 650W to platinum 860W

However, the PSU efficiency is not constant; it changes with respect to how much load on the PSU. Take a look at the efficiency graph of a Cooler Master PSU.

So, to make it clear, the PSU attains its highest efficiency at around 50% of the load.
That means should I get a PSU such that the peak draw is at 50% of the load? Nope in most cases
The reason behind it is because most of the time your PC is idling. However, there are some exceptions as well, for example, for those folding rigs.

Go for Seasonic, their PSUs very rock solid, they only use good quality components to built their PSU

Rosewill Hive 750M Bronze (HiPower OEM) "Modular" - RM 339
