650watt power supply!!!!! My microwave doesnt even have that much power..The list sounds pretty solid...only question I have is with the ATI All in Wonder....I thought those were being discontinued.
Looks good to me , but I would double check my wattage requirement by checking out the individual pieces of equipment. I am thinking you may be very close even with THAT ps.
Very nicely thought out, seems to me.

Nice list, but I'd definitely consider a GeForce3 card instead of the ATI. Otherwise, I have a question: Do you plan on powering the entire neighborhood? Hook in a deep freezer? 650w is a bit much... https://discussions.virtualdr.com/
Bistro, Train, et al...
week or so ago I had that thread on coupling power supplies...
In it, I started listing the power requirements as I found them on the devices and on specification sheets I found on the www ( one of the keyword was electrical ), rather than using generalised requirement estimates.
(for the requirements one reads are often the total power used, which is good to know, but of no help to find out about required output on 3.3+5V (mobo and IO) and on 12V (motors).
why not have people here add specifications of a few components.
the thread I had would be perfect for it
this was the thread http://discussions.virtualdr.com/For...ML/004496.html
in page two 2 listed these requirements.
hi all
let's try do some rheumy antics
main concern is still the combined load on 3.3 and +5V
(on which I have 150 watt)
the configuration changed since the athlon has been put in a new motherboard, with DDR and RAID on board....
*3.3/5V & 12V peripherals
= 6 Watt- 14 Watt- scsi plexwriter (values on drive)
= 4 Watt- 08 Watt- scsi harddisk 6.4GB (values on drive)
= 2 Watt - - - - - - floppy drive (no info on 12V, so why does it have 12V??)
= 3.5 W - 08 Watt- REMOVABLE BAY
= 3 Watt- 07 Watt- 40 giga diamondmax during use
= 3 Watt- 07 Watt- 40 giga diamondmax during use
+ 3 Watt- 07 Watt- 40 giga diamondmax during use
+ 3 Watt- 07 Watt- 40 giga diamondmax during use
= 3 Watt- 07 Watt- 30 giga diamondmax during use (source maxtor.com)
- - - - - - 02 Watt- a typical fan has less than that
= 4 Watt- 10 Watt- 16X DVD normal (12v=16 Watt peak)ACER source
note; 40 Watt per hard drive PEAK on 12V during spin-up...
______________________________________________________________
drawing power off motherboard
-- 3.3V -- 5 V - - 12 V - - device ON motherboard
-- total 47 Watt---??----- Athlon 1133 load (some of them early buggers use up to 70W...)
-- total 30 Watt---??----- motherboard (guestimate, no values found, EPOX 8K7a+)
-- total 07 Watt- 04 Watt- ati Xpert 2000
-- total 12 Watt---------- guestimate on old scsi 2940AU PCI
-- total 20 Watt---------- 10W per 128MB (wouldn't DDR use less? Currently 256 DDR)
-- -- -- -- - -- -- -- -- -- got a raid/DDR board so I don't need the hotrod in there.
-- total 15 Watt -- -- -- - two NIC and modem
+ playing with the idea to put the hauppage TV primio card in it...
(sound on board)
for hard drives, I took the higher requirement during read write, because I figure that when it does that, it isn't doing a seek. would that be correct?
-seek requires a bit less than read/write-
maxtor source
excerpt = maxtor POWER REQUIREMENTS (Average)
Mode---------+12VDC+-10% - +5VDC +-5% -Power
----------------------------------------------
Spin-up (peak) 2950 mA - - - 430 mA - -41.2 w
Seek - - - - - -550 mA - - - 510 mA - - 9.5 W
Read/Write - - -600 mA - - - 550 mA - -10.0 W
Idle- - - - - - 350 mA - - - 500 mA - - 6.7 W
Standby - - - - -30 mA - - - 150 mA - - 1.2 W
this looks much LESS bleak on the combined maximum load for 3.3V and 5V than it did before, does it not?
(seems I would be only about 25W short on 3.3/5V under normal operation after I add the stuff I want to.)
and have room left on 12V under normal use
(about 80W used)
+ zero (SCSI CDROM. Currently in use in other machine. It can stay in there...)
+ TWO 7200rpm IDE drives on highpoint (future total of four)
https://discussions.virtualdr.com/ HMMMMM, seems I had better get me larger drives...
= drivecoolers (on 12V)
+ 20 W second stick DDR RAM (currently 256 in one stick)
https://discussions.virtualdr.com/ but what a huge 12V peak-load at spinup...
over 260W PEAK

Hi
everyboduy is still under the impression I still buy SCSI.
I had a need for them once (reliability while burning on machines of that era), but no longer need buy them.
btw, the system above.
WOW.
gotta be a scorcher.

No real need for the "average" user to consider SCSI hd's anymore. The ATA's are giving them a run for their money as far as speed/performance and are more cost effective anyway. jt: you might consider one of them thar' new-fangled 650W Enermax's...power to spare. Y-extenders won't make much of a diff at all.

You misread the article. It is a powered unit in which you can put your SCSI harddrives that you have. In otherwords it is a slave for your tower. Just connected by the external SCSI cable. Must admit it would take a load off your PS. What I was looking at anyway.

Looks like a real screamer machine! https://discussions.virtualdr.com/
But i would suggest a Turtle Beach sound card rather than the SB.

Hi,
my load has been further distributed over two machines by now.
the iwill got a IDE burner today, and it has the DVD. The spare SCSI subsystem is gone from Iwill.
I have put the hotrod in there, to allow for hard disk data recovery "attempt" operations.
all drives currently in there are single masters... even the removable tray bay...
(gotta be able to do data rescue/ghosting on failing drives/on machines to be rebuilt)
the SCSI burner hdd and cdrom is in the big one, with free connectors, and a bit of power to spare.
(as I said, I have re-distributed stuff)
so far, I see no power related glitches.
when the time comes, I just get me bigger drives...

..SCSI - do I hear someone calling my name..? Or is it just the wind playing tricks on my mind (SCSI, oh SCSI, where art thou..?). https://discussions.virtualdr.com/
If I may put in my two cents here on SCSI: Right, SCSI harddrives (& CD/DVD) are costlier than ATA, but right now the prices seem to be going down, at least for the smaller hard drives (9 GB & 18 GB). Not to a level comparable with ATA, but it's a good start.
Having experienced som dire trouble with ATA drives lately, I'm once again turning to the - in my humble opinion/experience - more reliable SCSI drives. In my time with computers I've had 3-4 times more failures with ATA drives than with SCSI. I can't tell why that is. The mechanics can't differ that much, right?
The difference is primarily a question of different interfaces. It may be that the higher price is due to better quality - I'd like to think so, but don't know for sure. In fact, I've only had one SCSI drive gone bad on me in 6 years (I'm currently running 4 SCSI drives and have a couple more lying around waiting to switch places with ATA drives). I've even had sparks flying from a SCSI drive - it's still running, now in it's third year.
I recently did a little testing with a IDE (ATA66) and a SCSI DVD drive, both of them rated at 12 x. I did the testing while the machine in question (2 x P3 600 MHz/W2K) was quite busy doing something else during the test.
W H A T A D I F F E R E N C E I N S P E E D when used for real!! The SCSI drive was able to rip the contents of a DVD to harddisk about 4-5 times faster than the IDE drive. At no time did the reading speed of the IDE drive get above 3x. The SCSI drive averaged a speed of 7x.
I know, I know, it's not really a fair and scientific test - but it's the sort of test that I can use, since that is how MY system runs quite often.
I think that if you really want/need speedy drives you have to go SCSI all the way. Not just the HDs, but the CD/DVD too. The speed of SCSI really comes to play when all data transport can be handled by the SCSI controller. ATA can not run data both ways at the same time as SCSI can. Try connecting a HD and a CD burner a master / slave to the same ATA controller - you're running the risk of buffer underflow. Connecting a SCSI HD and CD-burner to the same controller will give you no problems.
SCSI controllers often have an external connector for scanner, zip, camera , what have you...and a decent SCSI controller will give you room for up to 7 or 15 devices to be hooked up. ATA, well, 4 devices and off you go to buy an additional controller card. Ok, now we're talking power user/system - not the avarage system.
Still, there's the price question. A SCSI DVD drive will probably cost you 30-50 % more that a comparable IDE drive. Larger (> 20 GB) SCSI HDs will cost you a lot more than ATA drives. So the trick seems to be to put the right mix together in your (power) system.
I'll still buy SCSI drives/devices anytime when the purpose is to move large amounts of data fast.

GG1,
I'm too lazy to go back through and read everything...where do ya stand now? What's the latest on the parts list...any changes?
And of course the most important question...are you going with the current MYST 3:Exile or are you starting at the beginning with the original MYST? https://discussions.virtualdr.com/

Good Morning All, After lengthy studying and price comparisons, the info you all have provided, I will change my MOBO to AMD. Now I have to determine what speed but am leaning towards 800 to 1GB. I will stay with the Inwin case. I believe I gan get a MOBO and CPu for under $200.00.
maxx, I have two 40GB HD and RAM. Ordering case, MOBO/CPU this weekend over the internet. https://discussions.virtualdr.com/
