Powering future pelts

phreenet · 03-12-2001, 09:07 PM

Well I was wrong, just plain watercooling doesn't cool any better then the alphas I used to have. Ok now time to move on, im going to get two ICE-71 80watt pelts, one for each processor. The pockets are empty so I cannot really afford to buy another PS or some fancy PS from Pyrimid. I have a 431watt Enermax PS, can this puppy power the two pelts? I also run DVD, CDRW, two 7200rpm HDs, and a crap load of Panaflows, 6 in all.

Well, I'd estimate that each TEC will draw a steady 6amps each. There's 12amps eaten away already by just the TECs on the 12V rail.

Look to see what your PSU is rated at on the 12V line. Anything over 12amps is what is left to power everything else.

Seriously you must have been doing something wrong...

phreenet · 03-13-2001, 04:35 AM

Kevin: I dont see what. I have a everything hooked up right, the water flows. It stays about 10F over Room temp (about 80F). So right this minute, it is staying at 91F, its on a PIII 933@1051, the core is at 1.82v. I have a Panaflow 92UIA which is a very highspeed fan, moves well over 60CFM through a Hayden 4x4 Radiator.

CK42: Ok the specs are 15A Max / 18A Peak for the 12v "rail". Humm doesn't sound to good. What about the 5v "rail" what uses that, jeez I have 44A Max, I wonder if the Hard Drives or CDRW/DVD uses that?

OK I just checked it out, If I get a Enermax 530watt PS it can put 20A to the 12v. Which I guess is better than 15A. Arggh this is going to suck

Not to try and get you down but even with the 20A 12V rail, that would still only leave you with 8Amps for all your 12V items.

Even most 300W PSU deliver 10Amps on the 12V rail. This would mean that you are basically using the equivalent of a 250W PSU for all your 12V items after the TECs get their share of the current. Would you be happy with a 250W PSU powering all those goodies in there???

If you have a meter that can read high enough, what you can do *if* you know what you're doing is to rig up the PS 12V line so that you can measure what your current 12V requirement is...w/o the TECs in the system. This amount of current would then be added to the 12Amps of the TECs. The total would tell you how much current you need at 12V from a PSU.

If you don't feel comfortable doing this, DON'T! You could possibly cause some major damage if you mess things up and I'd HATE to see that

good luck.

phreenet · 03-13-2001, 09:37 AM

Ok I can read AMPs, I just have to hook up the meter to one of the 12v rails as the computer is running right??

Damnit I dont think any of this is going to work, the Kyrotherm program tells me that the Amps per Pelt will be 5.55A x 2 = 11.1A total. My Enermax is rated 15A, so I guess im screwed. Ok so I am going to get another PS. Anyone know of a good PS that can do at least 14A on 12V and around 300-350watts, other criteria: It must be around $50.00. I will bridge them together so they both start up at the same time

phreenet:

To read the current on the 12V rail, it would prolly be easiest to read each device in the system using 12V one at a time.

But, you have to remember that you would want to know PEAK current draw, like when the hard drives are first spinning up from a cold start, or when the fans first turn on...that kind of thing. Otherwise, you may underestimate the current requirement.

phreenet · 03-13-2001, 12:54 PM

Ok CK, I dont think that this PS will work right, I am going to get another PS, do you know of one that will have like 12+Amps on 12V ?? Im looking for a computer PS so I can bridge the green wires so they both start at the same time. For around 50 or so dollars?

Unfortunately, the one that I got which is the same exact shape and size of a regular PSU but just puts out 12V at 17Amps for about $60 is no longer available at the place I got it.

I'll look around and see if I can find something in the meantime...sorry.

phreenet · 03-13-2001, 03:27 PM

Who makes it? and is it a computer PSU or just a general PSU

It's made by Twinfly model: P1-200-12.

It only has the 12V output so it's not a computer PSU in the sense that it's an AT or ATX PSU

But, otherwise if you were to look at it, you would think that it's a computer PS. It even has the fan in the back and all the same mounting holes to screw into a case just like a regular computer PS has. Same size and shape as an ordinary computer PS.

AhHA!! I just checked the link to that unit. It was a dead link for several weeks. I thought maybe they sold out and weren't going to carry it anymore...BUT, it's back! Check it out.

Yeah thats cool. I might think about getting it. Im going to look through the Jameco and Digikey catalog for PS. Ill post what I think might work in a minute

. Life is looking up now

http://www.jameco.com/cgi-bin/ncomme...&search=123422 <--- how about that. It is 150watts total and it runs 12VDC@12.5A
and if you have the newest Jameco catalog its on Page 96 lower left hand corner

How about that?

Well, it's not a standard type of PSU casing for one. So, it'd possibly be more awkward to mount.

Second, it's only 12.5Amps while the other one is 17Amps and is the SAME price.

Not sure why you would choose the Jameco one. Some particular reason?

phreenet · 03-13-2001, 04:32 PM

LOL, I dont know. I liked their service the last three out of three times I have ordered from them. Yeah you're right, Ill get that one you showed me and if I get my watercooling straight like I want to it will be cool

If it makes you feel any more comfortable, I know of several people that have bought these same units from them. I have also done quite a bit of looking around trying to find a PSU for my TEC and this is the one I finally decided on.

Didn't have ANY trouble with the company. Got the unit fast and trouble free.
