Thread: To the experts

this isn't really an expert question ... but no matter.

post the specs of your proposed system.

200W is plenty of power ... buuuuuut ...

In short I'm going to guess that this isn't the best solution for you. I'm not familiar with the PW-200... but if it's like the other PW series supplies, it doesn't condition the 12v line. In a desktop PC with a desktop hard drive, this is a bad thing.

The ITPS will condition the 12v line ... but it does a pretty crappy job of it. Because of the linear regulator it uses, you need to feed it abour 13.5v in to get 12 out ... which means it's only good to you when the car is running.

The ITPS is really only usable when you have all laptop components ... even then it's not ideal.

You'll be much happier with an OPUS or even the Carnetix 1280 with a PW series Ps (which is what I use ... just upgraded from ITPS)

Well, all last summer I used my desktop plugged into a inverter. Every now and then if the car was ideling for a while, the inverter would beep saying "NEED MORE POWER", so a few shots of gas, it was best kind.

So this summer, I will have the following:

P3 800
Asus Mobo
Sound BLaster Live
cdrw-dvd rom
512 ram
80 gig Maxtor 7200 spin
on board video

all in a plexi glass custom case.

So maybe I should just plug it in like I always did and get a ITPS so I don't have to power up/down every time.

Opinon?

ITPS is crap.

Requires 13.3V in to give 12V out, and it only provides 60W of regulated power.

Get an Opus 150W. Power supply is the heart of your system, and something you really should get right...and it's cheapest if you get it right the first time round.

From my experience it's cheapest to get the Opus straight away.


I've had an inverter + desktop PSU, a Morex + ITPS, and THEN i got an Opus.


I wish I'd found this forum sooner and had someone tell me about the Opus before I'd bought the other things, then I would have saved lots of money.

Well, do you know for one used or cheaper?

Well, I'm making the case myself. The cd-rom was going to me a normal one, but I can get a laptop one. Would that reduce the power usage?
