To be fair from a pure performance perspective RAMBUS is pretty nippy. PC1066 outperforms PC3200, it's only the cost/availablility which hurt rambus.
As for worse inventions, I'd say maybe the Voodoo Rush, that kinda sucked

we had a Q-Tec fitted as a replacement PSU when the previous one blew (never saw whether that was a Q-Tec or not) It's been going steady for 2 years now but it's not powering much (Athlon XP 2.2GHZ+, 512MB sd ram, 9600XT) I still run everytime I turn that computer on though

It's the big mistake thats made too often, Spend a fortune on components, And then go out and buy a Qtec. I'd say it's like buying a Ferarri and then urinating in the the Petrol Tank
Custompc magazine did a PSU group test a few issues back. You can find the review and labs test results at:
www.custompc.co.uk
click on labs then the psu group test.
"Q-TEC 650W Triple Fan 24p [Custom PC]
COMPANY: Q-Tec PRICE: £36.49inc VAT
RATING:
ISSUE: 26 DATE: Oct 05
Verdict: Steer well clear of this Q-TEC
Q-TEC power supplies are very popular because they're so much cheaper than other brands, but, as our testing shows, they're cheap for a good reason.
This particular Q-TEC is rated at 650W, but even before we switched it on we had our doubts, as the case is nearly empty. Q-TEC claims its PSU has a 30A 3.3V rail, 45A 5V rail and a 30A 12V rail. The Q-TEC doesn't follow the guidelines of the latest ATX spec, which recommends a second 12V rail if the load is greater than 18A. As the name suggests, there are three cooling fans: one 120mm and two 80mm. It supports both 20- and 24-pin motherboards, and has six Molex, two FDD and two S-ATA connectors, but no PCI-E.
The Q-TEC passed the 50 and 75 per cent voltage stability tests, although its efficiency at the latter setting dropped below the ATX spec to 68 per cent. This means that it was drawing a quite ridiculous 725W from the mains to produce 498W. The Q-TEC barely managed a few seconds at 100 per cent load before the voltages on all the rails started jumping up and down by as much as 20 per cent. After approximately a minute, it triggered the trip-switch of the testing lab.
As this PSU cannot even deliver 75 per cent of what it claims while adhering to the ATX spec, and will go bananas and shut down if you attempt to draw anything higher, we recommend steering well clear of it."

owch, 20% is pretty bad. I thought my .1v drop was bad but if thats true a vcore of 1.5v would vary from 1.35 to 1.65. Even at stock a system couldnt stay stable that way for long.
I shall check what they say about aerocool though I think its the motherboard in my case.

It is extremely bad - intels atx spec (http://www.formfactors.org/developer/specs/PSU_DG_1_0.pdf) states that 5% is the upper and lower most deviation so 20% is bloody outrageous.
The document also states that this is a guide and different system configurations require different power specification.
We actually sell this PSU but everyone has been trained that it is an EXTREME budget PSU suitable for a budget system, not an FX62system with 2 X 1900XTX in crossfire and 6 Hard Disks obviously.
Theres a clear reason why a 650W PSU costs £19.99... lol

You should put a warning sign by it, anyone overclocking should know better by now though. Chieftec make good budget psu's, Ive overclocked by 50% while using one and they are given free with cases..
The Aerocool gets 5 out 6 but not a good review, however

Any idea where this p84,94,96 might be as I can only see the 3 section heads at the top. I presume the article is a cut down archive and its not available now, pity as I'd like to compare it to a graph of me using s+m

Was about to ask the same question! The phrase under the ocuk logo is "only the best performance hardware" and on here even the ocuk tech staff state how poor they are, YET STILL ocuk sell them. Now for anyone not up to speed on psu's that look on this site and think that they only sell the best of stuff they'll go buy one and go away thinking they've got a bargin when they've really bought a living time bomb!!

Ive had an A64 system running on a 300w 4 year old case psu for a while now with no problems. A 650w qtec is probably capable of that much at least though I would never buy one they are ok for expendable cheap systems I think.
as my last post states and as some of you have agreed, they are an extreme budget PSU and we sell them as nothing more than this. Also, as some of you have stated, anybody remotely in the know will realise this. As I have said, all our staff are very well trained and orders are flagged by the sales team or the tech dept when asked if someone tries to buy a high end set of components with one of these PSU's.
Realistically, anyone buying a high end base rig and either crossfire or SLi would almost certainly know a budget PSU from a high end SLi or crossfire cerified one. We also offer free technical support and a full specifications link on our products as well as this forum so every opportunity to ensure the "right buy" is available prior to purchase.
We do stock "only the best performance hardware" but, more importantly, we pride ourselves on the expert technical knowledge that it requires. There is also a need to realise that not everyone spends £4k on a PC, most people don't spend that on a car..
The Q-tec is a perfectly good PSU for the purpose for which it is intended i.e. a budget system with "everything on board". It won't power a crossfire or SLi rig or similar spec. Expecting it to is like filling a formula one car with only 2 star petrol and still expecting it do 230MPH.
Its all down to knowledge in picking the right components, which is why we are here.

Visions of a glaring red WARNING sign next to every order that contains one of these PSU's come to mind. Rather amusingAndyOcUK said:
I don't know if you can tell me this or not but does that mean that if someone ordered that PSU with a high end component, OcUK wouldn't actually process the order without contacting the customer about the PSU?

When I worked for a computer company I was chatting to one of the guys about PSUs and he said he had a Q-Tec in his home PC and never had a problem with it, few weeks later he came in saying the thing blew up taking out a hard drive and cd drive he's lucky nothing else got taken out.

No it doesn't. It means that we give the correct advice to our customers because we know what we are talking about. We only sell this as a budget PSU and to be honest the clue is in the price. A 650W Q-tec costs £19.99, a 580W Tagan costs £81. It doesn't take a genius to figure out that there must be a quality difference when the Tagan is 70W less powerful yet 4 times the price.
Our customers will be advised and, as in my earlier post, we supply every opportunity for product research before you buy.
