I should have done this a week ago... But anways I got myself a propper PSU instead of the poser I was using a for the last month...
Well actually. The Antec Smartpower 2.0 450 Watt PSU is not exactly a poser. It's just not up to the stuff I need anymore... Throwing a 7900 GT and a P4 @ 4.0Ghz seems to drop it to it's knees... No everclocking the GPU at all.
So anyways. I did a lot of reasearch and decided to get an Antec Neo HE 550 Watt PSU. Wonderful PSU with 85% efficiency... Really nice looking not a bad price (came to $170 Canadian after taxes). So I get it home an plug it in all good. But wait... The computer won't turn on... So it goes back to the store... Turns out that all current gen Neo HE PSU's from Antec do not work with Asus boards... I thought it was an Intel only problem but it occured with some Asus A8N-SLI and A8N32-SLI boards too. So in otherwords I cannot recommend the Neo HE as a reliable solution...
But anyway I was looking at the OCZ Powerstream 700 Watt PSU figuring that should do the trick for me. But my local shop wants me to wait three weeks for it... But another local shop offered me an Enermax Liberty 620 for $250 canadian (after goverment contributions - taxes). I got that and all is working good now. I can heartily recommend the Antec Smartpower PSU's and the Enermax Liberty PSU's (I must comment that the packing on the Enermax is first rate but then for $250 it better be...).
