    Q-TEC 550 Watt : love'em or hate'em

    As a couple of you may know ive been hunting for a beefy radeon lately, 9700pr/9800pro to replace my loyal but weak Gf4mx440...but with them comes beefy power consumption...and i pressume that the need for a beffy PSU to power my 2.2xp,DVd,Cd-rw,512ram,2 HD's and soon to be beefy GPU is important.

    Where ever i go i hear the cries of Antec and Enermax where PSU's are concerned, these both seem to be the market leaders in PSU's, as with all market leaders with a good reputation they have high prices

    I noticed this little fella:

    "QTEC 550 Watt PSU P4 ready Twin Fan Retail Boxed" on ebuyer fot £25

    Is this a fake with just 550 for packaging or the real thing (i understand most psu's cannot actually stay at their peak of 450/550 as displayed on the box for an amount of time)

    I also see contradictory reviews of this.. some singing its praises some daming it to hell.....

    for example

    "The 550w is delivered from the fact that it can peak at a certain amper. However this PSU can only sustain 409w!
    O/P - peak - max
    3.3V - 30A - 20A = 3.3x20=66W
    5V - 40A - 35A = 5x35=175W
    12V - 20A - 14A = 12x14=168W
    In total this PSU can sustain a maximum of 409W.
    If someone presumes this PSU can output a constant of 550W and builds a system to output this amount of power, prepare for the fire brigade!
    However for systems that just require a smoothly running PSU without heavy power consumption this will suit"

    opinions and experiences on this thingy??

    Tah Adam.R

    (on seriously tight budget considering i need 2 get card also)

    PS: also heard good things bout sparkle which are good and a bit cheaper than antec etc

    Never had one, but I've not heard good things about them.

    Antec provide the best power - at least that's the general consensus. I run an Enermax - they're a little weak on the 5V but good otherwise.
    PHP Code:
    $s = new signature();
    $s->sarcasm()->intellect()->font('Courier New')->display();

    There was a thread on this not too long back, ill try and dig it out.
    It seemed like some were fine, some had serious problems. Ill let the people who have had no issues come and have their say, i just want to get mind in first.

    These things are crap. Really really crap. Do NOT waste your money. They are NOT 550 watt. They can sustain that for something stupid like 1/10th of a second.
    Ive had 1 go up in smoke, and one just die taking out the motherboard.
    There is quite a few reviews on ebuyer for them, but take a closer read of them and you'll see maybe 1 in 10 knows what they are talking about. It only has 14A on the +12v line, so once you start banging a few higher quality / faster components in there it will start to struggle.

    Q-tec "550" watt = £20.10
    Antec True power = £99.42

    The prices should speak for them-selfs !

    I actually have one, but to be honest, I am going to replace it as soon as I come into funds (the 9800XT just wiped me out big stylee lol) main reason for replacement is that mine has a wierd rattle, quite annoying at times, at least it stops after about 15 seconds of boot.

    Its powered my kit amicably, but the ThermalTake Butterfly has my eye right now, 560W of power muhahah

    Just gotta find one at a good price now lol

    Frosty, definitely not, I had an AMD system before this with a Chieftec PSU and that motha used to crash twice a day, and it turned out to be the power supply, this one is rock solid, I think its froze on me one in two years, and that was my fault....

    I have been running one since last october ish and my system is 100% stable and quieter than previous PSU - I got it as I thought my 9800 needed more power.

    By the way my system has 1 DVDR, 5 HDs 9800 pro, fans etc

    I have a few, one is paired with an antec 400 running my dual MP machine, lots of SCSI and full IDE use but only a GF4. However it has been faultless and I only reboot every month or two. The other 550w runs my P4 server, again with all IDE used and 2 raid setups (8 devices in total), voltages spot on and again a reboot every few months.

    I suspect it can be hit or miss, but if you're on a tight budget then I havent found better for such a small cost.

    550Watt QTecs are noisy, and cheap - theres a reason!

    One of these suckers took out my MSI K7N2G-ILSR back in the summer, remember how expensive those boards we're
