Antec PSUs = CWT PSUs - best evidence so far

malfunction · 14-12-2003, 02:20 AM

After looking into this a bit more (because of this thread: psu) and comparing the specs for the PSUs on www.antec-inc.com and www.cwt.com.tw I'm now 99% confident that Antec PSUs are in fact re-badged CWT PSUs (as has been mentioned before).

Basically all the CWT PSUs that Scan are selling - apart from the 550W - seem to match the Antec Smart Power PSUs exactly. The 550W though seems to match the Antec TruPower 550 (as there's no B series 550W CWT PSU listed on the CWT website).

So I reckon:

Antec TruPower = CWT 'A' series PSU
Antec Smart Power = CWT 'B' series PSU

The main difference between the TruPower / A series and the Smart Power / B series is that the B series has a combined rail for 3.3V and 5V whereas the A series has separate rails for all three.

Prices taken from eBuyer and Scan to give a quick comparison (inc VAT but excl delivery):

450W CWT = £34.65, 450W Antec Smart Power = £61.55
550W CWT = £59.93, 550W Antec TruPower = £98.39

For what it's worth apart from comparing specs this is based upon the fact that I recently upgraded from a 380W TruPower to a 450W CWT PSU and the external appearance of both PSUs was indentical and the internal appearance similar.

Anyway - believe it if you want to or don't if you don't but I reckon it's worth a go - esp. for the 450W model which is basically cheap as chips for a decent 450W PSU.

Spazman? you ordered two of them they must be good

I've got the 450W CWT PSU, it does look like an Antec, it's very good, quiet and my pc is very stable now i've used it as a replacement for my Q-tec 550W PSU (BOOooooooo!)
