ISO. Ever heard of them? They like to come free with foxconn cases. Some of these cases can be had for cheap, so lets see how good these are, are they fixable, or are they another leadman with no hope? Here I have the ISO-400, sounds like a 400W, but is really a 300W. Tricky tricky. Anyways, here is a overall shot:
Plain grey box. Thats ok, I got this for free from a friend who is building a computer, the case was $30.
Here's the label, UL number leads to Channel Well Technologies. No surprise, ISO is known as channel well's budget line. Budget line...that is not usually a good thing to hear, but Channel Well is because they can build some pretty good units.
Here are the connectors. Not too many here, a 20+4 pin connector, 4 pin cpu connector, 2 molex, 2 sata (one missing the 3.3v wire,) and a floppy connector. All wires are 20 gauge, with 22 gauge on the floppy connector.
Well, here it is. First impressions are ok. Better than the usual "450W" off brand psu. I see a full input filter there, with a .47uf cap on the ac receptacle, 2 .1uf caps elsewhere, a coil, and 2 Y caps. Real 4A, 500V bridge rectifier, real 35 sized transformer. Fan is provided by Jamicon, rated at 32.52 cfm, and 27.8 db. It is relatively quiet for running on 12v constantly.
Better view of that, note the ceramic fuse.
A commodity generally missing from cheap psu's. MOV's. Nice. Brand of those caps are Jun brand. Same color, series, and cursive font as the FHY brand found in my, now junked, CWT 235W built Broadway 550W. The FHY and Jun caps have the same series as Asia-X.
Here are the primary switchers. Two fairchild E13009L's, not off-brand parts or no-name parts generally seen in cheaper ones.
Secondary silicon. 5v is in the middle, rectified by a 30A, 45V ST part, 3.3v on the right is a 20A, 45V ST part, and the 12v is a 16A, 200V Philips part.
Secondary caps in all their glory. JunFu and Fulltec. All suspiciously use the same series, HK, and have the same vent stamping, all similar to Asia-X.
Heres how the caps break down (only measurements of diameter, height not much of an object here):
12v : 1x fulltec 16v, 330uf 6mm, 1x fulltec 16v, 2200uf 10mm
5v : 2x JunFu 10v, 2200uf 10mm
3.3v : 2x JunFu 6.3v, 2200uf 10mm
5vsb : 1x Fulltec 10v, 1000uf 10mm, 1x JunFu 10v, 470uf
A standard TL464 is used here, along with a TPS3510P, which provides OVP for 12v, 5v, and 3.3v, UVP for 5v and 3.3v. Still no OCP.
Overall, it seems pretty honestly rated. If you had no other choice and needed a psu to temporarily power a low-power computer, I would say go for it.
