Well, remember that thread a long time back that I started asking about the quality of this power supply? Well, I finally got a hold of one, a brand new one too. Boy, logisys and keerda (the OEM) must have been watching that thread, because it is MUCH different than the one I saw back then. I was meaning to get pictures about a week ago, but the crappy camera I was using crapped out and couldn't take pictures. Sheesh. Anyways, I've done some upgrades since then, so these aren't completely original pictures. I'll point out my upgrades though.
Lets start with a label shot:
How well did the secondary schottky's agree with these? Well, it had a 30A, 45V schottky on both the 5v and 3.3v, so no go on those. But, the 12v had a 30A, 200v schottky on it, so yes there.
Now a overview of the entire unit:
It's actually not that bad looking of a unit. I like the sleeving on all the cables, but it doesn't go all the way up all of them. The cables are good. On the 24pin connector, they are all 18 gauge except for the negative voltage wires. The cpu connector is 18 gauge, too. The pci-e connectors are more disappointing, being 20 gauge, same with all the disk drive connectors and two, yes only two, sata connectors.
Now with the cover off. You can see the transient filter over there, came with a nice coil and two 2000pf Y caps. The original X cap was a small .1uf one, replaced with a .47uf one. The bridge rectifier is a 600v, 6A part, I added that heatsink. The main caps are 200v, 820uf. What brand? This is the shocking part, I will cover that.
Don't know if you can see it, but those are Nippon Chemi-con's. Yes, I did not add those.
Primary switchers, two D209L's, 400V, 12A units. You can also see the two transistors for the 5vsb.
Secondary schottky's. This unit is definitely designed to be more modern, as it does not have spacing for two schottky's on the 5v, but on the 12v instead. I took advantage of that by adding two 60A, 45v parts there. Yup, 120A of capacity on there. A 70A, 30v part regulates the 5v, and a 60A, 45v regulates the 3.3v. No, I don't overbuild my units
Secondary caps. I replaced the two caps for the 3.3v with nichicon PW. The rest are unchanged. Anyways, heres a short list:
3.3V - 2x 10v, 1000uf BH 105C LESR
5v - 2x 10v, 2200uf BH 105C
12v - 1 16v, 2200uf BH 105C and 1 16v, 680uf BH 105C
The small caps are some BH, and others are Nicon. I haven't heard of them, but they have the same series names as UCC. KME. Probably just imitation.
Now, keerda makes some OK units, this one is a ATX-300A. The OPP set for this is a about 300W, and this is how keerda/logisys got past it. They removed a resistor that controls the OPP. I want to find the value of the non-ripped off one and fix that.
The fans are BanDiKai brand. Nope, never heard of them either.
Overall not that bad of a unit if it weren't for the secondary caps and the ripped off OPP resistor. Though, you can't take all the blame off logisys because keerda did it for them and added two pci-e connectors to it.
