I'm trying to decide if it is a good decision to purchase an AMS 300-Watt ATX Model: CF-2029. I already have a case(but i'd really like to get a new one.),and all I would really actually need to do is purchase a PSU. Or like I said, I can go all out and buy the AMS 300-watt case instead.

My question is, should I buy the AMS case with the 300 watt PS or just get the PSU alone(thinking of an ANTEC PS)? I understand the ECS K7S5A PRO needs a quality PSU to operate correctly. I could puchase the AMS case for the same price, if not chaeaper than say an ANTEC PSU alone? However, I'm hesitant to get the AMS case because it has only 300-watts. I did some research on the PSU and this is what I found out.

+3.3v @ 14A
+5v @ 30A

So, the TCO would be 196.2 w.

I have read from null min. s/b 300 watts, but recommends a 350 watt PS. Has anyone had any personal issues with a low watt PSU's and the ECS mobo? I have read so many complaints with individuals not having a "quality" PSU. When people mean "quality" are they refering the wattage or the workmanship of the PSU(or a combination of both)? AMS is also on the "AMD recommended" list.

Thanks.

14 amps on 3.3V is extremely wimpy, and chances are that the fine print limits the TCO even further than the sum of the two. I've seen "300W" PSUs in bigtower cases (!) with a 3.3V/5V TCO of 110W. Ridiculous, and hardly enough for an Athlon-1000 and a Radeon 7500LE. (In fact, that's what I'm using right now ...)

Get yourself something more serious.

My current build with my ECS K7S5A Pro has an Enermax 350w PSU.


I would always recommend spending a little extra on a quality PSU like Antec,Enermax,Sparkle etc since it`s really worth it in the long run,PSUs are one of the most important parts IMHO.

Mine gets by on an older Sparkle 300W non Athlon approved but occasionally funny things do happen.

As I said, there is a wild variation in "300W" power supplies. YMMV, but with those cheap cases, one usually does not get a proper PSU.
