The PSU is equipped with the following cables and connectors:

• Mainboard cable with a 20-pin connector (44cm long)
• CPU cable with a 4-pin connector (45cm)
• Additional mainboard cable with a single-row 6-pin AUX connector that used to be installed on certain mainboards a few years ago and is altogether missing in the modern industry standards (44cm)
• Two cables with two Molex connectors and one floppy mini-plug on each (45cm from the PSU case to the first plug, 10cm between the Molex connectors, and yet more 25cm to the floppy plug)
• Cable with three Molex connectors (60cm+15cm+15cm)
• Cable with two Molex connectors (75cm+15cm)
• The above-described heap of adapters

There’s utter confusion as concerns the wattage of this power supply. The name of the model seems to imply 560W, but the label mentions a peak load of 600W (without specifying what the term “peak” means here and what the maximum non-peak load is). The table contains a total of 600W with something which goes without the word “peak” (and I really wonder what is the purpose of declaring output power with one decimal place precision). So I have to carry out an experiment again.

The experiment ended with the following outcome: the power supply burned down in less than a minute at an output power of 540W. It was again the inverter’s transistors that proved to be the weakest link and the consequences were very picturesque:

I had unsoldered the high-voltage capacitors to make this photograph. The transistors are an impressive sight indeed with their burnt legs and pieces of plastic torn out of their cases. The surrounding components are covered in soot and copper from the legs of the transistors. Some of the copper paths on the reverse side of the PCB had just evaporated, leaving a black smudge on the PSU case.

I didn’t have a second sample of the PSU, so I had to shorten my test program. I hadn’t measured the output voltage ripple and the efficiency of the PSU before its death, but considering the similar circuit design, I think these parameters don’t differ much from those of the IW-P430J2-0.

The cross-load characteristic of this PSU isn’t perfect, but overall acceptable.

The PSU is equipped with two fans from Delta Electronics, an AFB0812H (80x80x25mm) and an AFB0812HB (80x80x15mm). They have similar speeds that are changing within a range of 1500-3000rpm, making the IW-P560A2-0 an average-noisiness model.

Telling you the truth, the purpose of this model’s existence in 2006 A.D. is a mystery to me. This power supply might make an acceptable midrange product if the manufacturer declared a wattage of about 450W for it and equipped it with normal modern connectors instead of the heap of adapters. This product would have a chance then even despite its compliance with the ATX12V 1.3 standard because it provides 25A on the +12V rail as opposed to the previous model’s 18A. The marking of this PSU doesn’t make it clear what exactly wattage it has, and installing it into a modern computer makes it necessary to use a lot of adapters, most of which are absurd and some even look alarming (yes, I mean the graphics card power adapter). The IW-P560A2-0 comes to retail at about $90 and there exist much more interesting alternatives from a number of manufacturers for that money!
