Qtec are recycling old power stations I bet ;)
At least they've included the address for RMA's in the advert :p
Nah...it's a 350W, but they're counting the heat output as well :devilish:Quote:

Complies to latest PFC power distortion standards - distortion! :shocked2:
230V input voltage surely they means watts output!
Low voltage power switch - to enable your system to burn before it destroys your house
Noise level less than 29dB(A) - 29dB lower than a jet engine they meant
Gold colour - Im impressed this got a mention
Product size (HxWxD in mm): 85 x 150 x 170 - the only good thing!
I feel like crying!
Still, it doesn't beat the 800watts I'm getting out of dual PSU's... and that's from an Enermax & Antec... so the figures are a little more reliable.
Whats wrong with those Qtec PSUs. They are good quality arn't they? I have one, a 550w. Other power supplies can cost you loads!! These a good cheap option. I can't see why you'd tajke the piss outta 'em!

Its got something to do with them occasionally going bang and taking out other hardware with them - mobo's etc ...Quote:

Its like a mini lightening storm in your case waiting to go off!!!
the 3 fans are to help keep the flames alight as long as possible :)
What do we reckon the real power output is on this baby. I'd say somewhere in the 300-350W bracket.
I love QTEC bashing threads :)
Watch that ebay item go for quite a lot as the village idiots start to bid
wooooo 650 watts
I once sold an enermac 300w PSU on ebay and I decided to package it in an old Qtec PSU box. I bet he crapped himself when he opened the packaging.
yup, mine blew up and set on fire taking my mobo, cpu and hard drive with it.
ROFLMFAO :)
Insurance companies should have a clause in PC cover that states that they do not cover damage caused by civil conflict, acts of god, or QTEC power supplies.
Anyone with a QTEC PSU reading this thread should seriously run to the nearest supplier and aquire a 1/2 decent PSU before their timebomb waits to go off....
tick...tick....tick....
hehe.
i need a new psu, replace my antec, ill go for this.
qtec rule.
I still have no problems with my Q-tec 550W PFC I bought from a guy for £15. Been running fine for almost a year now. Of course they aren't as good as more expensive PSU's, it does show in the voltage rails, and therefore are not the PSU's to use for Overclocking; but I have been running my XP2500+ at stock with no problems, and if you look at my sig you will see my system does not have low power demands at all with 3 HDD's and 2 optical drives.
EDIT: Besides, if it blows and takes my system with it, what better time to upgrade ? :D Insurance money will go a long way when I bought it all at PC world prices ;) ;)
When you buy these more expensive rip off PSUs at like 80 qid for 350w youre' just paying for the name, as with most things. Why pay LOADS for a 350w if you can get a 550w PSU for 20 quid, like my QTec. Its myth that they blow up! That would be illigal if they actually caused fires etc, QTec are a respectable company arn't they? Making all kinds of computer parts!
I had a q-tec 550w running my system for about 8 months and only upgraded it when it was running out of juice (too many hard drives). However I did upgrade the fans in the psu - the ones in it a crap, that might be why it lasted longer, but when you've got a pc that costs £xxxx why try and save £30 on a psu when it can ruin £xxx amount of gear.
I had no problems with mine - but saying that I wouldn't have another one.
That is one of the finest examples of Hexus helping people....nicely worded man :) Yours was OK, but you kinda feel you got lucky, and have learned a lesson the comfy way.Quote:

Hmmm - my q-tec 550w was in a heavily clocked and over volted nforce2 rig with 6x80mm fans 2x optical drives 2x ide hdd 2x scsi hdd, 9800 AiW, 6x usb devices - all the rails were a tad low (12v 11.6, 5v 4.8, 3.3v 3.2v) but it was stable. When I added another hdd on top of that lot it started to cut out quite frequently.Quote:

Anyway most of the cheap 550w PSU's can't actually hold that output, real output would be like 350-400w. With the more expensive PSu's (like my Tagan for example) they provide a steady voltage output and it can stretch to something like 500w (iirc) at peak output.
Nuff said
mine was running 2 hard drives, an overclocked XP1800, 2 optical drives and a Geforce 4 Ti4200.
When it went it killed just about everything except the RAM.
And yes it went bang and threw out lots of black smoke, the molex connector to one of my hard drives was partially melted and there were flames for a few seconds from burning wire insulation.
Now I have an FSP/Fortron PSU and I wouldn't go back.
Thats not the case at all. Just becuase it says 550w does not mean it can sustain that. Its a case of peak output (and heat in QTecs case :D) ie it can sustain 550w for several seconds but thats it.Quote:

The problem I had with a QTec 450w PSU I had was voltage spikes which will eventually damage hardware, that cost me £30 at the time. Switched to a 420w Hiper PSU and all my apparent instabilty issues on my old rig disappeared and voltages where rock (initially) but I burnt out 3 voltage regulators on these Hipers, switched to a Tagan and no problems at all. Extremely extremely quiet and very effiecent.
The Tagan set me back £70 but I trust it and know its gonna be reliable which is a damn site more than In had with cheaper PSUs! That Tagan powers everything in my sig ince my water pump (DD 12v), 6 120mm fans, 3 80mms, highly OCed CPU and everything else above 12v, 5v and 3.3v!
At the end of the day you get what you pay for ;) do you see Daewoos lasting the same length of time as an audi or volkswagen?
No offence, but this is a dedicated computer hardware forum.Quote:

what does that binary mean under your name, mgh0?
so, if i was to buy a better, safer and better quality PSU when i upgrade my system sometime soon, what should i get? Bearing in mind i have two optical drives, about 7 fans, 4 hard drives and lights. I want a 550w surely to be able to comfortably power it, but i dont wanna pay more than 50-60 quid. How do u know that the name is correct, unlike Q-Tecs as it seems. If it says 450W then how do i know its actually 450W? :)
*loads up goolge and searches for binary translator*
It means "handbags are for n00bs" :P
http://www.scan.co.uk/Products/Produ...roductID=59492
These guys make Antec's PSUs.
i was just about to link to exactly the same PSU as kez :)
I have one of these: http://www.blacknoise.de/shop/de_DE/...400-60_PN.html
And its fantastic, silent and ultra stable rails.
"hangbags are for n00bs" ?! WTF does that mean? You mental people!
It was a thread in general chat last week, Hexus Pink Handbag day.. :)
I have no idea mate, but there was a thing the other day with people having pink handbags in their sigs :crazy:Quote:

Back on topic - most people round these parts like CWT psu's from scan or Tagan, both are good value for money.
Qtec's are cheap and chearfull PSU's
In a unstressed system they do provide very good result and a fast response
to differences in power drain maintaining decent voltages.
However they do get to a point where they keel over far sooner than a decent
PSU.
As with all PSU's its can be crafty wording but the quoted watts will be correct
what's rarely discribed is at what temperature that measurement is taken at.
Qtec 550 if I remember right are rated at 25deg for the peek output in comparison to
say a top range PCP&C TurboCool 510 thats rated at 40deg for its 510watts so in reality your prob
getting 350+ out of the 550 quoted on a qtec 550 considering 40deg+ is a typical
Psu running temp.
Noticable difference in abilities are also noticed when modding a Qtec 550 with modded
5/12v rails and 3.3v rail shows no noticable improvements and negative effects are
seen due to elevated temps where other e.g. enermax for example stand up and deliver
that bit extra against the same mods.
i do like Qtec's for systems that are not stressed as such but would never use one
in a decent system.
I would rather spend an extra fiver-tenner over a QTec just for minds sakes, if a PSU blows and takes the HDD, mobo out etc on a system you've supplied that means your out of pocket replacing the parts!
Even on an unstresses system....better to be safer than sorry!
I think it says a lot that QTEC do not state the voltages on their website of the different rails.
totall agree Goreblast.... very suspic! Any decent PSU manufacter posts their rails!!!
i've never owned a Qtec psu. nearly bought a 550w one when they first came out though.. damn idiot in shop saying "yes they are good, good as any other psu" - thank frap i didn't have the £ and didnt buy it. my mate had one, and it blew, killing the L2 cache on his great clocking 2500 barton :Oops: - never had a PSU kill a rig yet despite running a XP2100 pally system 24/7 on a £3 300w (165w really) screamer - didnt have the £ again to get a decent psu :rant: got a Antec Smartpower now though :rockon:
/me pats his very nice enermax :D
I just had an Antec TrueControl 550W self destruct - thank god it only killed itself and nothing else.
PSUs are an area where I don't think it makes sense to economise; I've seen enough cheapie PSUs blow - and nastily, too, taking the motherboard or CPU or both with. My work rig runs off an Enermax 550 and my home rig off the 380W Antec in the Sonata. Both reasonably quiet, and very very stable. Why spend £160 and up on your graphics card if you're planning on frying it with a £10 PSU?
nichomachs got a point there, u get wot u pay for, if u pay a cheap amount u get cheap stuff, it isnt really a bagrain, its just tat
Some people earlier were on about rails. What are rails, and how does the PSU temp effect the output?
rails are the voltages ie the 12v, 5v and 3.3v lines. These are very important BECAUSE you want stable rails ie that move within +/- 0.5% less than that is ideal. Unstable voltages and low voltages makes for a very unstable PC!
Temps affect PSUs because they are only so effecient. Its the same as CPUs really. If they are hot their losing too much power to heat and not producing enough. Companies like QTec put 550w cos thats how much it can peak at, at 25c for 5seconds as companies like Tagan, Enermax, ThermalTake etc etc put the maximum sustained voltage so a Tagan 480w produces 480w whether the temps 12c or 45c. It peaks at 560w I believe.
