I just made this account here to voice my suggestion. I'm a nobody, ignore me if you like, but this comes from my experiences at LinusTechTips forums.
 
I'm not going to claim full responsibility for this, but when I first came to LTTforums literally every thread where someone was asking for power supply suggestions was filled with recommendations to buy the Corsair RM Series. Even when they weren't appropriate (for budget or Wattage reasons), and often people would recommend much higher Wattage units than needed. Someone even said to me they were some of the best power supplies ever made. I began challenging people whenever they recommended an RM Series unit, asking them why they believed it to be so good, pointing out the poor capacitors, and giving other suggestions. Over time, the climate has changed. Almost all threads are now full of people suggesting the EVGA G2 Series, unfortunately even in situations where they need ~500W. Which brings me to my first recommendation.
 
1. The RM Series is increasingly uncompetitive at higher Wattages. At the 750W mark and above, they're demolished in price and performance by the G2's and others. When looking for competition around the 550W mark however, I realized there aren't very many fully-modular 80Plus Gold units. The RM550 makes the most sense of all the RM Series. XFX's XTR 550W would be nice, except the availability is poor, and the reports of XFX's customer service aren't exactly stellar. To outcompete the RM550, you need a fully-modular, 80Plus Gold 550W unit with comparable performance, better capacitors (preferably full Japanese), good aesthetics and silent operation, and the ability to say "Superflower-made, ~9.7/10 Jonnyguru.com Recommended". In my experience on LTTforums, semi-modular won't cut it, and anything below 80Plus Gold won't either. They don't buy for the electrical performance. They buy because of "Silence-Optimization", "80Plus Gold certification", and "Full modularity", and the aesthetics of the RM Series.
I'm not sure what you were thinking when you made the G1 and B1 Series, but to me the G1 Series was a perfect opportunity to extend down to the lower Wattages with competitive Gold-rated units that people like me could really recommend over the lower RM Series. Something like the Cooler Master V and VS Series'. Maybe the G1 wouldn't be as good electrically as the G2's, and maybe the OEM would be different (See next point), and maybe the capacitors wouldn't be 100% 105C Japanese, but it would hold its own against the RM450+, and maybe beat it in performance or price. Do this, and you could make the entire RM Series uncompetitive.
 
2. Drop FSP. Nobody is raving about the performance of your NEX units. They're coasting on the reputation you've gained with Superflower. Many people I see on LTT recommend the FSP-made units and reference a jonnyguru review of the G2 750W as though they were the same series. Superflower made you in the PSU market. You would be an NZXT or Fractal Design if not for the deal you struck with them. You aren't branding your FSP Aurums with Jonnyguru.com recommendations for obvious reasons. They haven't reviewed them (which probably isn't a coincidence), and they just aren't that impressive.
And it looks to me like you're branding the new FSP G1 Series similarly to the G2 Series, possibly to continue misleading people into buying or recommending those units. Please don't do that.
 
Corsair right now is coasting on their reputation, lowering the quality of their cases and power supplies, and keeping the price premium. You have the opportunity to really damage Corsair's reputation and take a lot of their market from them, and I believe Superflower is the key to this. Remind people of the quality that Corsair was known for, and then show them how your products are better in every way.
Also, send a review sample to Linus. If it survives being thrown off a roof he thinks it's because the PSU performs excellently. His audience is large, and a couple of his reviews of the RM Series was the reason they were recommended so widely.
 
And a tip you might like to know. Power supplies are overpriced here in NZ. Availability isn't good, and the only real options are Corsair and Cooler Master. Feel free to burst onto the scene, displacing the $458NZ RM1000 and other overpriced Corsair units. See if you can make a deal with PBtech. They have your GPUs, but not your PSUs.

And if the T2 1600W is up to scratch, market it as the AX1500i Killer.
At every turn, remind people that your units are Killers, beating Corsair's products at every turn in performance and price.
