here's a very simple review of the 550 (http://www.viperlair.com/reviews/cases/other/psu/atlas/) that includes a couple of internal shots.

the 550w was once reviewed here, but the review has been lost.

A-45GA Delta, A50/55GA AcBel Polytech?

[panca saputra jaya]

yes correct, A50-A55 are acbel's old model (atx 2.01)
identified from its large PFC-choke

Hmm, the OP must be intrigued by its decent price in our local market -yeah, he's from Indonesia i believe, right bro ? ;) Welcome to the forum :). Is this Delta unit a modern design one, with double forward topology and aPFC, or is it an old half bridge design one ? How does it compare against, say a Corsair CX 400w (Seasonic platform), CWT DSA platform, or FSP Saga II 400w (all of these three competitors are using modern design and priced in the same segment, not much money separating all of them) ?

The ASUS is based on the GPS-450AA. Here's a review of Chieftec's version: http://www.xbitlabs.com/articles/coolers/display/chieftec-psu-roundup.html#sect1. Not all that impressive. I'd probably choose any of the others you listed before these.

@shinji2k, thx for the info mate, truly appreciated. It seems quite decent, though as you say, not really all that impressive, just good enough to power most low to mid end gaming system without breaking it in the long run. It was priced around 15% cheaper than Corsair CX 400w in my country, doesn't seem all that competitive indeed, unless on a really tight budget.

[shinji2k]

It definitely isn't bad. But for a little more I would certainly grab the Corsair. Oh and to answer your question about the topology, I'm not completely certain but it looks like dual forward to me. But it isn't all that efficient though, it's an older design. I'd probably choose it over the Saga though. IIRC those are overrated a little and I don't have much confidence in FSP.

this 400w (www.coolaler.com.tw/image/js/400w/01.jpg) class will be damn good

[spursindonesia]

@Panca, ho ho, JS PSU, so you say that not only moderating a PSU forum, now i manufacture PSU too ? ;) :D Seriously, is that a new Acbel unit ? Or else ?

@Shinji, i've seen that Saga II 400w unit torn apart and dissected + analysed component by component in my local forum, seems pretty competent as a modern 400w unit, double forward topology with aPFC, complete transient filtering stage, protection circuitry, etc. It has 28 A on its combined 12v rail, but judging from the components, that rating is somewhat conservative, though it still needs to climb up the load tester desk to be sure.

Here's the link (In Indonesian): SAGA II, Review.., by G2_Support @CHIP Forum Indonesia (http://forum.chip.co.id/fsp-psu-represented/131804-saga-ii-review.html)

Plenty of internal shots and components info at your service. :)

@spursindonesia: bro,
taiwan local brand
it's enermax pro82 :D

[spursindonesia]

Is it quite affordable ? If the bussiness calculation makes sense, bring it home and distribute it here, my friend. :)

[panca saputra jaya]

still wondering :D
won't be cheap enough because of this (http://www.coolaler.com.tw/image/js/400w/05.jpg)
