Have I just Been One Hit Killed?

What was the PSU that people used to buy ages ago? Q something. They used to blow up all the time and take mobos, cpus, gfx and everything else with them.
Q something, or something Q.

Q-Tec

and don't pretend like you never had one :D I know I did at some point.
 

:D I had the Q-TEC 650W Triple Fan 24p... in my P4 system at the time.. Never trusted it and the fans needed cleaning all the time.. Only good thing I can say is it's still working fine it seems... Sold the PC to my landlord at the time ... He's chuffed to bits with that pc to this day... :cool:

Guessing for the P4 setups its fine anything more then that and they will go bang...


Never buying cheap power supplies again after the last headache I had with this system I have now.. I purchased one of these

http://www.overclockers.co.uk/showproduct.php?prodid=CA-044-OK&groupid=701&catid=123&subcat=1709

but was called something else at the time by a different supplier... It would not even start the system up correctly. All the fans would run and no post or anything... Replaced it with a Corsair TX750 booted up 1st time... :D

LOL yes that Gold case pulled me in and the high wattage they stated the supply could do... reality of that supply ... "This means that it was drawing a quite ridiculous 725W from the mains to produce 498W. :eek:"

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.
 
Thanks for all your help, i now definatly understand not to skimp on the psu, im gonna go spend some good money on a coolermaster 750w hopesully that will do the trick unless anyone has any other recommendations for under £80?

Btw i update the post.
 
Believe it or not I still have a q-tec psu running a barton 2500 system at my sisters. Its been sitting overclocked to 3200+ on that psu for the past, must be 4 or 5 years and the psu is still going strong. Its crazy slow but its old.

I must have been one of the lucky ones :)

I recommended the Corsair TX650W on the first page. I think Corsair PSUs are the best quality.
 
Ha Ha the lovely old Q-Tec! Ohhh I remember them things, all the rage with thousands sold for as little as £12 and everyone loving them and then they all started turning into little bombs... POP POP POP BANG BWOOOSH POP BANG etc etc! It was carnage.

In a cheap psu, even a fairly good one it is always mostly cheap chinese capacitors with such names as Fuyu?, CapXon, OST, Rulyon etc. There are more but I cannot remember the names. All I know is they will fail at anytime. Some will pop, some will just burn up causing a right stink. Some just fail and look perfect... Great fun... NOT!

I have a dead Antec SP350 that flamed and made a lovely stench, an Achme shuttle 200w psu that caused major problems and an Antec NSK1380 psu that burnt itself and really made a bad stink. All failed due to capacitors. With a little time and money I can probably fix all three and make them work properly! The antec SP350 can actually be re-capped and modded to output a much better 5v rail. Why oh why didnt they just use decent capacitors in the first place rather then skimping on a few dollars or whatever they use for currency lol.
 
Im glad i got the OCZ ZS 650w,i was using an OcUK swift 550w that cost 20 quid before but only used it for like a month and a half,im sure if i used it for any length of time it would have blown up!

Remember its not the watts that count its the amps! A 650watt PSU with like 14-16 amps on the 12v rail is gonna be crap and blow up especialy when its a cheap one ,however a good quality 450watt PSU with 35 amps on the 12v rail is MUCH better even though its rated at 450 watts its actualy supplying more power than the crappy 650watt and no nasty voltage spikes that can kill components!

Id get a good quality 550w-750w PSU so that you can upgrade later and it will last a long time,the 570GTX can draw a fair bit of power! You want something that will last.Buying a cheap one is a mistake id never make again and your thread just reminded me why i should stick to that principal!
 
But if you do that then it kills your shiny new card you've lost out in every single way.

well said!


OMG i used to have one of those,it lasted for years though and i gave it to my cousin who used it for years too but he bought a new one because it was ready to blow up and making his pc stutter lol.I guess we were very lucky indeed!

No idea why people buy these £20 psu's and expect them to be good just because they have a large wattage number on the side. If its cheap, its cheap for a reason! Cheap and nasty components mean that it will go bang and take most of your rig with it! Get a good psu!
