    I got a copy of CUSTOMPC magazine (www.custompc.co.uk) the other day because it had a big article on PSU's...they tested 31 different units in 2 groups <500W and 501W+.

    There's a lot there, I would type it up but to get the real information from it you need the graphcs and every little detail, there's too much so I'm sorry.
    Get a copy of the magasine if you can though, it's a very interesting read.

    You could at least mention which ones failed/exploded. :) Otherwise your post is pretty worthless to the forum goers, especially those of us who don't live in the UK.

    Okay here's the ratings the Magasine gave them and from the graphs which ones failed.
    The Percentage Scores were worked out from Stability, Features and Value so a PSU with 100% Stability and great features may be brought down by the fact it's expensive.

    The tests were 50% Load, 75% Load, 100% Load and 100% Load for 30 minutes.
    These PSU's failing doesn't mean they just stopped, although a lot of them did when they were put under load some of them dropped below the ratings/limits for the ATX Spec. None of them supplied too much voltage surprisingly enough.

    Thanks for the article, Matt555. Very informative. Also illustrates why I recommend overspec'ing PSUs a bit over what you technically need. One question though, which ones physically failed (i.e. caught fire)?

    I'll have a look...
    *looking*
    Okay
    Aerocool submitted 2 PSU's for testing, the 550W one the gave them blew up straight away (could have been a bad unit though)
    Ultra X-Connect 500W
    Antec True Control 550
    OCZ powerStream OCZ600ADJ-EU (overheated, unpleasant small, shutdown and no more powering on)
    I can't find which other ones did, I'll keep looking though, some started to smell funny and get rather hot though, if 9 exploded I do wish they would make it more clear exactly which ones as at the beginning of the article where the main picture and PSU's to be tested are (names not descriptions) it says "To find out which PSU's are the quietest and most stable, which can really do what their manufacturers claim and which six blew up during the 100 percent load test, read on"
    So six blew up during the load test, make it clear then, in the graphs it shows a zero for PSU's that failed but that could mean they just turned off...bah

    Ahh, intersting. I have had a bit of experience with that Antec True Control 550, and I don't like it. That being said, it has an external potentiometer that allows you to overvolt each rail, repsectively. If you don't have the potentiometer connected at all, the PSU will undervolt severely. I wonder if they had the potentiometer connected? If not, the PSU would run at about 1/4 of its capacity. I suspect this may be the case, as I've found that model of PSU to be quite solid, although I doubt the usefulness of a potentiometer on a PC power supply.

    All the best,

    Yeah that could some disasterous effects, someone could severly overvolt their system...bad idea I think

    Well I guess that's the second review to have one of those Ultra X-Connects explode...not good. They seem to have issues when stressed from what I understand.

    Yeah and yet in that extreme PC garage they used 2 of them to power a very high specced machine including 2 7800GTX's in SLI...okay so there's 2 of them but they still fail...silly, very very silly

    Very nice Matt. I was very surprised to see Antec, OCz, and Thermaltake PSU's as unstable and undersirable. Looks like Seasonic is the way to go:good:
    Thanks man.

    All of the PSUs are listed by watts, but what I'm even more interested in is the amps, and on which rails they failed.
