So I looked for PSU's, I found a couple but looked on to see if I could find something cheaper but above 600W..

I found this... The price? 400 NOK, that is less than 100 USD!!!!!

Is there a big big major flaw on this PSU or is this a must buy before stock runs out?
I can't find a reason not to buy it, please look and see if you can!! 1 in stock!!!

I don't remember the exact URL but look it up and make sure it doesn't have ripple issues or voltages changing drastically under load.

EDIT: A quick Google shows a lot of ripple and a lot of failures due to the cheap components. Don't be cheap mate...

I did a massive google search... and sadly..

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

ADVERTISEMENT
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.

*cries*

Thanks guys.

Q-Tec PSU's are cheap for a reason, they're not very reliable at all.

You can get an Ultra PSU for about the same or less. I would trust them over Q-tec any day.

it appears to be a bomb disguised in PSU form...
Damn transformers...more than meets the eye...*****.

Get a fortron sparkle! They're cheap AND good.

Seasonic is the best PSU for any money really...so since it's so cheap, look for one of those.

yeah that would have been good at the time but i was a noob back then...didnt really understand computers...funnily enough that psu was what took my last rig ...just didnt switch on one day...athlon xp3200, msi something motherboard, gig of ram and a nvidia 6600gt gone in a flash...or rather a pop with an unpleasant aftersmell

Ahh man. I wasn't taking a shot at you like that. It's just that it sucks to see people cheap out on the PSU in a nice rig. Think about it like this, would you rather have a GTX and a cheap PSU that is going to take the entire rig out ina matter of months?, or get a 320MB GTS for much less and get an uber l33t PSU that won't fail on you until you physically abuse it?

And even then.. it might work if you're a sissy.

If you don't have the money to buy a good PSU, then you don't have the money to be building a quality computer. Either save up more, or cut back on other components. If your PSU blows up, who cares how good the rest of your stuff is?

And why does that piece of crap have 3 fans? My 650 watt silverstone only has 1. There's no reason to for a PSU to have more then 1 fan.
