A little help about some PSU and PSU's platforms

[Theadess]

Hay,guys.

I need some explatations about some of the platforms PSU (Sesonic S12II, Sesanic M12D or CWT DSG, CWT PSH and other).

What is the difference between S12 i S12E? Which is better? How S12II quality of S12E and S12?

What is the difference between CWT DSG and CWT PSH? Which is better? What about the CWT PUC platform?

The platform was done Antec Signature Series? Whether it can compare with this Seasonic and CWT platforms?

Thanks in advance.

S12E is a revision of S12 which achieves 80Plus Bronze efficiency.
S12II is a cheap group-regulated low-to-mid-range design.
DSG has a bit higher wattage than PSH, and uses SR and DC/DC on secondary design to achieve 80Plus Gold/Silver efficiency. The ripple is lower than PSH too. DSG has a 80Plus Bronze version.
PUC is for 1KW+ so it's unfair to compare PUC to DSG IMO.
Signature's topology is similar to DSG other than it's half-SR on secondary whereas DSG is fully-SR and M12D is rectified by conventional Schottky on secondary. Its efficiency is lower than M12D and DSG by 1 to 3 percent.

Thanks for answer Travis.

Signs that the CWT DSG and the quality of approximate Seasonic M12D.
What about FSP Epsilon platform? Can it compare with Seasonic i CWT platforms? SS ST50F OCZ SxS and 500 are based on the FSP Epsilon platform?

What you think about Chieftec and LC Power PSU? Kind of quality they?

FSP Epsilon can't compare at all to the CWT PSH or DSG...and it isn't as good as the S12E either. The Epsilon is an OLD platform and it wasn't any good for more than 500W when it launched brand new.

Chieftec uses a bunch of different OEMs...CWT, Highpower
LC Power uses a bunch of OEMs too...CWT, Superflower, Andyson etc.

Thank for answer.

Yes, I know who is the OEM Chieftec and LC Power PSUs. I need your opinion how much are these really high quality PSU? How much is a good on which it is based on Metatron / Arkangel series? How much is really quality of the Antec CP series? What is the situation with Antec CP vs Antec Signature series?

I hope that you will not be difficult to answer on my questions.

Thank in advance.

The Arkangel is just a CWT PSH...so no better than any other CWT PSH.

The Antec CP are good...just look at the reviews from this site...but they are totally different than the Signature...and of course are not the standard form factor, so only fit in the Antec cases built to take them.

LC Power uses a bunch of OEMs too...CWT, Superflower, Andyson etc.Wich LC-Powers are Superflower made?

BTW: you forgot the most important: Huntkey and Great Wall...

[HOOfan_1]

Wich LC-Powers are Superflower made?

mistake...I thought I saw one once
