I'd take an Enermax any day over those others. I've used them all. I like the Antec PP303x, and the SparkleFSSP-300-60GT is nice too. But, the Enermax Whisper series is just the cream of the crop, IMO. I recommend the EG-351P-VE very highly. It has 2 fans, one 92mm ultra quiet that draws air from the case (meaning the hot air over the CPU) into the PS unit, and the second 80mm fan blows the air out of the back of the PS unit. It's got all the latest features like a thermal probe that you can let hang in the middle of the case, 3-pin fan header to connect to the mobo, fan speed control by temps, nylon mesh wire wrap to keep the wires neater (not necessary, but a nice touch) and to top it off, it's 330W.
