content: The part numbers already indicate power and voltage so it is quite easy to see if any match your requirements.

content: RQ is a model serie(s)65 is wattage = 65 watts total ouput, a mix of voltages and current multiplication(s)all other models show are based on the same principle ...

content: not rocket science to take the model numbers and do some searchthe model number is a give away ??and all the electronic or mechanical specs can be found ...i smell some laziness lollthe seller has no obligation to give more specs ?

content: tggzzz is correct. After the first two or three lookups the potential buyer will probably be too bored to continue. So what if it's laziness or just an unwillingness to waste time on a pointless hunt (you don't know if you need these without looking them up, so why invest time on something you probably don't need?). The seller wants to get as many potential buyers as possible, and ideally wants each item to shout "BUY ME!!! YOUNEEEDME" as the viewer's eyes drift past.Or perhaps the seller isn't really interested in selling them. If he can't be arsed to just say WTF these things are, is he going to take the trouble to make the sale a painless operation?

content: Quote from: coromonadalix on August 10, 2023, 02:26:22 pmThere is only one seller, who should be familiar with the specifications anyway, but hundreds of potential buyers, who want to just quickly skim through the buy/sell 'adverts', without having to copy/paste and google a large number of unfamiliar part numbers.So, just listing a list of parts numbers like that, is probably much less likely to achieve a sale.I'd also suggest including the desired selling price.

content: This is it in a nutshell...Quote from: MK14 on August 10, 2023, 03:41:53 pmCould you imagine a retailer having product on the shelf displaying ONLY the model number - no specifications? I mean, EVERYBODY could do a Google search on their phone to find out - but .... that doesn't seem like a customer experience which would generate a lot of sales.The responsibility for enabling sales is - and has been for centuries - upon the seller.

content: Quote from: Brumby on August 11, 2023, 10:50:01 amAlso, this 'sales advert' has been up for longer than 3 months. Well described and sensibly/realistically priced popular power supplies, could sell on here, much quicker than that.Edit: On the other hand, the sellers DON'T have to provide easily read descriptions and/or desired asking prices, to post here. It's just that by missing that information out, they may not get fast sales, enough interest in the thread, or even any sales at all.

content: TDK-Lambda aren't always quite so clear on their product naming. I have a couple of NV175s here which I've snipped the model information from the dataheet (attached)

content: QuoteI may be thick but I couldn't decipher that model number. Specifically, the 7 doesn't match owt.edit: Ah, I suspect it's not the full number and 'NV175' is the prefix to the stuff in the table? Well, just goes to show if you're not already au fait with a product a picture would go an awful long way

content: Quote from: PlainName on August 11, 2023, 02:58:38 pmLol you may be but I doubt it. The 175 refers to the power rating, obvious, no? OK, no.Look at the table below the one I posted earlier to show what a dog's dinner they made of their naming convention.

content: are we gonna start a war on the specs .... or some exceptionsok some models are in the void ...but generally speaking, many brand use the wattage and voltage schemein the end, some push the responsibility to the seller and i would say, do yourself a favor by searching specs ...if it sells or notif the OP is in a hurry or not etc ...the price(s) are ok or not etc ...
