Does someone know how reliable is the Q-Tec 550 Watt PSU ?
I didn't found anything on such PSU on THG files. This PSU is very cheap but I am afraid of its reliability.

What max currents is it rated for on each of its rails? Then we might be able to see if its a decent one or not.

I don't believe always to the features reported in the side-label. Anyway it reports: +5>35A, +3.3>20A (MAX +5/+3.3 = 285 W), +12>14A.
I have edited my original post because, sincerely, I forgot the specifications for the PSU. After I went again to the computer shop I wrote the data and reported them correctly.
The link given for the Q-Tec test is very interesting. Maybe I will buy the stuff (60 Euros)

I have to do a choice between an Enermax 365 W (max 185 W on 3.3 and 5 V) and the Q-tec 550. Quality or numbers ?

With that lable and the positive review posted above the Q-Tec sounds very good for its price.

My dual-PSU PC is so powerfull that the neighbourhood dims when I turn it on :eek:

well for a direct comparison the enermax 550W i have is rated for: 3.3V = 40A 5V = 46A 12V = 24A.
So as you can see there is considerable differences, despite them both being "550W psu's"

Personally i would get the lower rated enermax... You may not get quite as much total current able to be supplied, but quality counts and ive heard of very few enermaxes failing.

Thanks LHG
You convinced me, even because THG tested the Enermax 365 W and it cames out a real power of about 390 W which is absolutely enough for my need.

Woops I was wrong... get the Enermax... the Q-Tec has only 14A on the 12V rail. Looks like I misread that.

5>35A, +3.3>20A (MAX +5/+3.3 = 285 W), +12>14A.

35A @ 5V = 175W, 20A @ 3.3V, = 66W, 14A @ 12V = 168W. Add about 20W or the negative and standby voltages, and you get a total of 429W, or far less than 550W rating. It also makes no sense that the combined power rating for +5V and +3.3V is 285W because that's more than 175W + 66W. Are the discrepancies due to misprints or to bad arithmetic?

PSU producer(marketeers) like to state the max Peak power.
