145w Power Supply

I am looking at a micro-atx case that I plan to build a Duron system in. The system will include the following:

Duron 750mhz
ECS K7SEM SiS730S MICRO ATX Mobo
20Gig 5400RPM Hard Drive
Sony 52x CD-ROM Drive
Creative Modem Blaster
ATI Xpert 98 Rage XL 8MB AGP Graphics Card

The system would just be used for email and maybe some light web surfing. The micro-ATX case that I am looking at comes with a 145w P/S (It is an Inwin Case). Is that going to be enough?
 


<< it might do the job but I wouldn't recommend it >>



Is any old power supply going to fit in this micro atx case? Or do I have to look for one specially designated for micro atx?
 


<< Has to be a Micro ATX PS... www.directron.com has a 200w one, that's about the largest I've personally seen... >>




Do you think that will be enough? BTW thanks for the help so far.
 
I've built dozens of systems using a 145W microATX case/PSU and have never had a problem. They are great little budget machines. Used mostly Duron 750's on Biostar KM133 boards.
 
I have an In win IWV-700 that came with the 145w Ps and I replaced it with a regular, more powerful ATX PS. The PS that came with the case is the same width and height of your standard ATX PS but it is about half as deep. So when I put the full size in my case, it just takes up more room on the inside. Even with the increased depth of the PS, there is more than enough room in the 5.25 bays for your cd-rom and what have you without it being cramped. You didn't mention what model you were looking at so your miliage may vary.
 
Put it this way, AMD recommends at least a 250 watt power supply for any of their processors so 145 is just too small in my opinion. If that is all you can get then definitely change out the power supply for a bigger one, preferably a 300 watt. You're better off just getting a better case with a bigger power supply. Just my .02
 
For those who keep saying that they have a 145 watter in their system and it works fine, by working fine do you mean only reboots a couple times a day or do you mean you have very few power eating components in your system. My guess is the latter, which is fine if you don't plan on adding hard drives, cdrw and stuff like that.

Apparently You Diddnt Read his Post


I Think that for what your putting in there you should be fine with the 145 watter..... If you Upgrade to a Geforce 3 & a 7200 HDD than you will probably run into some power related issues.....

Apparently you didn't read my post, particularly the part where I directed the question at people other than the original poster. Jerk

There's not too much other crap you can put into a microATX case or add to a microATX board. Ever see one? Don't see too many microATX setups with SCSI arrays and lots of other goodies. Most have room for 3 cards and 3 drives, that's not too big of a load. Never had a single one fail or have a customer complain about stability. And the AMD recommendations leave lots of room for slop.
 
Thanks for the input guys...btw, this sytem is not going to be upgraded or have components added. The only reason I am looking at a micro ATX case is for a PC for my Grandparents, who don't have a lot of space. Believe me, if the system was for myself or someone who had the room, I wouldnt use a micro ATX.

I might just end up spending a little more and picking up one of those Spacewalker barebones from Newegg. I have read some reviews (including the new one here at Anand's) and like what I see.
 
Just make sure it is a quality power supply. I've seen 250W PSU power machines that 300W generic can't. Especially if you go small: DON'T GO CHEAP! (unless of course it's a good PS that priced cheap, than go for it!).

I am pretty sure it's quality...it is an Inwin case. I believe they only use Powerman power supplies.
 
microATX was made for grandparents! The Inwin uATX case is a nice one, too. I've used many of them without trouble.
