(thank god cut and paste was invented)

doesnt sound too bad

What are you wondering about exactly?

wondering if its a good psu, better than the qtec 400wp dual fan gold I got and wud it handle my system ok.

Why did you post the same thing twice? Anyway CWT is a good brand to get. I have a 330w and it's has been excellent over the last year of service in GF's PC. HTH

The CWT will take almost anything you can toss at it. It is more commonly known over here as the Antec Truepower 550.

You sure? I thought Antec Truepower was a different company to CWT

100% sure - I have a few Antecs around here, and more than a few CWT's. This particular PSU is definitely the True 550, though probably lacking the Antec fans and fan only connectors.

CWT is the OEM manufacturer... Antec doesn't actually make them. There are quite a few companies that do this - take a PSU from a manufacturer, make a few alterations, and then sell them as their own. Silverstone, for example, uses Sirtec/Highpower units. In Antec's case, ever since the older Smartpower series, CWT has made all the ones I've seen including the Truepowers and SL's. A few of the pp units were Heroichi (HEC), but AFAIK Antec hasn't used them for a PSU supplier in some time.

Not that this is a bad thing - CWT is very hard to buy in North America... if not for Antec, most people wouldn't get to buy one at all. Considering the price/performance ratio of them, Antec picked a good source of PSU's

Wow, thanks for the feedback Oklahoma Wolf !!

So if they are both the same, it doesn't matter if I get the CWT 550 or the Antec Truepower 550. whichever is cheaper!!!

right?

Yep - as long as the Antec also has active PFC it's pretty much the same thing. The CWT model may also lack the fan monitoring lead present on the Antec, and may or may not be louder than the Antec (different fans).
