PSU gurus, can you please give me some advice?

[damocles]

I am building a new PC and have a choice of these 4 power supplies. I will be running a 1.2ghz Tbird (and beyond). Being isolated in the Antipodes I have only these to choose from

From what I have seen, none are certified by AMD above 1gihz (which surprised me), however I imagine all will be ok.

Enermax EG351P-VE 330W ATX Power Supply
Enermax EG451P-VE 430W ATX Power Supply,
PowMax LP-6100D 400W ATX Power Supply
Seventeam ST-300HR ATX Power Supply. 300W

The EG451P is pretty expensive and would like to avoid it if possible. Comments on noise etc would be appreciated.

Only have info about the enermax psu's.. They are supposed to used PAPST fans, so noise should be no issue for those.

What exactly you need in power depends on what other stuff you'll be puttin in the case. With a 1.2GHZ and a Geforce2 Ultra, the MB will need quite a bit of power, but the 330W should keep those two fed..

Using an SCSI/IDE Raid setup, and combine with some high-speed CD/DVD-rom and a CD-RW, you'll have alot of power-hogging devices. normal usage I'd advice the 330 Enermax. With alot of external devices, go for a more powerfull one..

Are Powmax a good brand?

Go for the Enermax,I too have a Enermax EG351P-VE 330W ATX Power Supply and it's a great power supply.

Enermax's are great PS's.
They aren't silent, but are quite quiet.

I've heard the PowMax's are very loud...The seventeam might not be enough power for your.

Give us your entier system specs (inc. fans, HD's, etc)

I'm with Viperoni, the 351 Enermax is a high quality piece of equipment, and extremely quiet. Only a mountain of really power-hungry stuff would begin to tax one.

Basically i'm not 100% what load it will need to carry. I want it to be my main psu for a couple of years. It basically has to power a big Tbird, a couple of IDE drives, next gen video card, not too much else except for std peripherals

The 330w PSU should be suffient for any configuration (within reason) that you throw at it. Assuming that you don't install like 5 scsi drives or a whole lotta peltiers you should be fine. The reason those quality PSU aren't on the AMD approved list is probably because it hasn't been updated in a long time. The power output of those would probably far exceed the requirements of AMD approval.
