PSU looks fine, and whilst I haven't bought a SuperFlower branded PSU in ages, I've used their supplies via other ODMs. I always have a soft-spot for Superflower as they were the company I turned to 25 years ago when aftermarket PSUs barely existed and the only PSUs you could easily get came preinstalled in a case. At some point in the Pentium overclocking days, I finally pushed the generic Chieftec/Chenbro unit too far and discovered how hard it was to buy a proper PSU. Enermax/Superflower were almost the only game in town back then....
Can we talk about their branding? Butterfly. Rainbow. Military font. Sans-serif font. Some old serif font. Italic and regular. Bold and regular. Wide kerning and narrow kering. A fifth font for the specs on the back of the box. Black warranty label and switches on a white enclosure. Generic black cables. The list of aesthetic booboos there is enormous and I'm not even done.
I'm not a graphic artist and yet basic graphic design knowledge has embedded itself in me simply through exposure to good and bad presentation. I wouldn't care if the box was ugly because that goes in the recycling bin, but the unit itself also needs some presentation work. It looks like a cheap, stamped-steel budget PSU with white paint as an afterthought and everything else just the generic black as always. For an RGBLED vanity build (not something I care about in the slightest) the physical appearance MATTERS. If you're not going to put the PSU on display you aren't in the market for a non-standard colour with RGBLED at a price premium.
So, IMO even though this is a decent performing PSU, it's a product failure - it's supposed to be a cosmetic showpiece as well as a PSU and it lacks class, consistency, style, and flair.
