Yes, you are absolutely correct. However, the reason all this ruckus is being made is because
due to the misleading power rating on the QTecs themselves, it is perfectly possible (and unfortuantely all too common!) for a user to buy this PSU for a system for which it is not only insufficient, but actually dangerous to run it in (not just for their rig, but for their homes and possibly lives)!
And while it's decent of you guys to try and dissuade customers buying high-end rigs from buying these, I'm sure there's lots of them being bought on their own, perhaps to replace PSUs that stopped working, which are being installed in high-end rigs!
I see your point that OcUK is a business, and that you're not in any way misleading your customers into believing these PSUs are as good as more expensive brands. But the ratings on the PSUs themselves ARE completely misleading and frequently lead to blown, worthless PCs. While I'm a big proponent of personal responsibility and am in no way suggesting that these "accidents" are the fault of OcUK staff, or even that you're morally responsible, it would be very much in the interest of your company to stop stocking such low-quality (and, indeed, mislabelled to a borderline criminal degree!) equipment. Flagging them with a warning on your catalogue is probably out of the question as QTec or their supplier could conceivably sue you for libel, but having people who don't know better going around saying they bought this PSU from OcUK and it blew up and took their Opteron rig with it is VERY bad for your company's image! If people are noobish enough to buy these fire hazards, they're probably noobish enough to not realise that it's their own fault for picking them (especially if they don't want to admit their mistake for fear of losing face), so they'll just go around saying they bought them from OcUK. I realise you need to stock a full range of PSUs, but I reckon the Akasas are cheap enough to be able to fill the "budget" end of your line up without the help of the Qtec white elephants...
And, to the OP, we want pictures of that thing's innards!
