Please help, two (actually 3) questions that have always bugged me:

1. "AMD approved"
What is that suppose to mean anyway? When did CPU's become so particular with PSUs?

2. The concern of not having enough power for these newer CPU's.
I thought CPUs only take relative small voltage to run (~5v, 3.3, etc). Why is there such a big concern on CPU/Power?

Sorry for my ignorance.

The "AMD Approved" sticker means that the power supply has been tested by AMD and has been proven to work without problems. CPU's have become very particular with PSUs over the past year or two. The higher power CPU's need a more stable and capable PSU. As for the concern with the power, it is all a matter of Current (amperes) not voltage so much. These newer and faster CPUs require that a lot of current be supplied. That is why you will sometimes see power ratings for PSUs shown as (for example only): 245W on the 5V and 3.3V rails combined. This gives you an idea of how much current the power supply can provide. If you know how much power is available at a given voltage, you can calculate current: Power=Current/Voltage. If you have a look at CPU specifications you will note the power consumed is nowadays in the range (usually) of 50W-75W. That is also why good cooling of the CPU is a must. (The rest of the power goes to the motherboard, PCI cards, AGP cards, USB ports, etc. And there is some 12V power thrown in there, too.)

AnMig was talking about the P4 connector on the power supply and was wondering what it was. It is just another cable coming out of the power supply that plugs into a specific socket on P4 motherboards. This extra connector provides extra power to the CPU. Early P4s required this extra power; I believe that later P4 processors and P4 motherboards have been updated so that the extra connector isn't required. (Don't quote me on the P4 information, it isn't my strong suit.)

Hope that helps.

Power = Current x Voltage... not Current/Voltage

Yeah, I realized my typo a bit later.

think you and user "wmwtom" are talking about different companys.Please see his link and the company you mentioned. It's 2 total different company. Please verify my point.

Yes, you are right. I am referring to original post, PCA Inc is a different company, it seems a sort of outlet for Linkworld. Their ratings are different, apparently better. My apology for whatever confusion there is but the company from the start of this thread "Infinity Systems Plus Inc." from Ohio is to be avoided, the comment stands.

got the case sitting at home as I type, so at least they are pretty good on shipping (free)
ordered 7/19/02 at night delivered 07/25/02 noon

The real test would be, will the 400w ps be able to handle my picky ecs k7s5a with a 1600 xp
if it is able to handle this then I will be more than happy.

will migrate my system to this case in the next day or so will post results

peace

PC-Infinity is pretty good. I've purchased 8 of these types of cases from them in the past. Things to know:

1. The metal is pretty thin. Something you would expect from an inexpensive case. I actually cut myself once on an edge when I was careless.

2. All 8 of the cases I ordered were the 300watt. HOWEVER, every case they sent me came with a 400watt PSU. It's obviously not as good as an AMD approved PSU, but most-likely better than a 300watt non-approved PSU.

3. The first time I ordered from them, I bought 2 cases. They charged my credit card twice though and sent me the same tracking number twice. Weird. However, I e-mailed them and they cleared it up for me.

4. Every time I ordered, the package either shipped the next day or the day after the next day.

This is probably the best cheap bang-for-the-buck case out there. BTW, the "300watt" was $25 a month ago. They raised to $29 or $30..

Oh, I haven't had a problem with this PSU and the K7S5A. I dunno how good the PSU is though.

Do you know if their Comet Mid ATX 300Watt Case for $35 shipped has a side case fan or not? or at least a hole for the case fan

Ok. Well, if you want junk, this guy

Bilsystem

sells real junk, real cheap. You just cannot beat him. And while I can find out numerous documented complaints for Infinity Systems Inc., I cannot find anything about this reseller, it just might be an honest salvage.

okay here is some more info about the case.
The case looks exactly like the one they had on the link (blue stripe)

It was the power supply I was really interested in.
Its a 400w PS brand is duro. the combined 3.3 and 5 volt line is 242wats

My line voltages with my 1600 xp ecs are

3.3--3.28
2.5--2.448
5----4.919
I believe these are all within 5 percent

Most important for me is that I was able to remove my duron and now have my 1600xp up and running and so far no reboots or freezes.
I still dont know if this cured my problem but things are looking good. Still have prime 95 doing torture test and will not call it totally stable until I have tested it for a week. (by the way its my 9 year old daughters computer, why I bothered to upgrade it escapes me at the moment.

The case does not look that bad it is about the same quality as the enlight cases they sold at newegg.
The PSU it replaced was a 300w enlight.

so as far as I am concerned this company is ok

peace

how is the 12 volt rail?

 

[AnMig]

this is in sandra the other numbers where in the bios

3.3--3.26
+5--4.87
+12--11.73
