do I need a power supply?

[gunslinger]

I have a few questions about my machine that I hope someone can help me with. I bought this computer from Gateway in early '04. It doesn't have a real graphics card, only Intel Integrated Graphics. I've been looking into a graphics card for an AGP slot, and I found the GE Force 6600 recommended on another thread as an AGP card that would probably run M2 fairly well. The specs for that card require a 300 Watt power supply.

I can't find any power supply listed in my system information. I ran my serial number through the gateway website, and it has a 250 Watt power supply listed twice:

Power Supplies

250-Watt ATX Power Supply R0 [Part #6500836] Support Docs
250-Watt ATX Power Supply R0 [Part #6500843] Support Docs


Please note the two different part numbers. So, does this mean that I have a 500 Watt supply, and I'm safe to get the graphics card, or will I need a power supply upgrade?


One more question, if someone will indulge me a bit. When I bought my computer, hyper threading was all the rage. I asked for an HT processor. According to the records at Gateway, I have a:

Processors

Intel Pentium 4 (Prescott) 2.8GHz/800MHz CPU R0 [Part #4501031] Support Docs

However, in the System Information on my computer it says:

Processor x86 Family 15 Model 3 Stepping 3 GenuineIntel ~2793 Mhz
Processor x86 Family 15 Model 3 Stepping 3 GenuineIntel ~2793 Mhz

Yes, it's written twice. In the Device Manager Under "Computer" it says:

ACPI Multiprocessor PC

So, do I have a dual core or not? Is it possible that Gateway could accidentally send me a computer with two processors? I'm sure I would have remembered it if they had told me I was getting a dual core. Remember, I bought it in early '04 when that wasn't too common.

I seriously doubt you have a 2.8Ghz dual core, Intel barely manages to makes those now :inquisitive: I know my 'system information' always teels me i have two gfx cards (wel primary and secondary) even though i have only one, it might be a similar thing.

As for the power supply I don't really know, I don't think I ever heard about two seperate power supplies in a PC case, but then I know very little about those...

I would suggest to get a new decent power supply with at least 400 or 450 Watt output. I had to get a new one with some older GeForce and an AMD 2400+ because the 250Watt thing didn't cut it anymore. Given that your Pentium uses roughly the same energy as the AMD, the Graphicscard should definitely consume a lot more so I'd go for a good PSU, if you get a decent one, you may be able to keep it for later upgrades.
Concerning your processor, ACPI Multiprocessor is most likely applied because HT simulates a second Core that doesn't really exist. Instead it uses free parts/ressources of the single core you have and uses them as if you had a second core. To let Windows take advantage of this, it has to pretend to be two cores I think.

Maybe you forgot to turn off the onboard graphics in your BIOS?

Nah, it's twice the same Radeon card that shows up.

You could simply try to delete one, may have to do with installing drivers twice or teo different drivers, I had that with some controllers IIRC and deleting them did no harm, if really needed, windows should detect and install them again.

Honestly, I never had a problem with it :shrug:

ok, so if I do need a new power suppy, are they technically challenging to install? Are they expensive to buy? Are there compatibility issues I need to know about, or will any 450 Watt power supply work with my pc?

It looks like I bought this computer at the tail end of two eras: HT and AGP were both fine when I bought it, and now no one is making new AGP cards and the HT is somewhat obsolete.

Depends on your level of comfort with the guts of a PC. Also depends on the model -- if your PC is a Dell, you're going to need to buy a Dell-compatible PS. PC Power and Cooling (http://www.pcpowercooling.com/products/power_supplies/selector/dell.htm) makes them, and I'm sure other manufacturers do as well.

When replacing the PS, you're going to need to re-cable most of your components. If that makes you swoon with fear, you might want to pay an experienced geek to perform the operation (or call in a favor with a geek friend, if that avenue is open to you).

If your PC is anything besides a Dell, a standard ATX power supply should do the trick. They do not need to be expensive, although you get what you pay for in this market. You should at least purchase a name-brand supply, such as a Thermaltake or Antec.

On the bright side, most video games are GPU-bound, not CPU-bound. So if you have enough RAM, and you can throw in a good AGP GPU, you should be in good shape for a while.

I've heard that videocard packages usually contain a recommended PSU number which is, usually, way higher than the PSU number which is actually needed. Is this even remotely corect ?

I'm asking because my Dimension (yes...a Dell) comes with a standard 250 W PSU, and it therefore seems necessary to get a new PSU device for me to play with a 350 W videocard. Now, obviously nobody likes to spend an extra 50 > dollars/euro's on a new (needed?) PSU device. So, is it absolutely necessary, or is it more of a precaution and investment in the future.

:balloon2:

hmm. I just came across a decent looking deal on a radeon 9550 256mb vid card. It has Shader 2 and it says it will run on a 250 Watt PSU. That should run M2, right? Any comments or suggestions?

The 9550's get good reviews (http://www.newegg.com/Product/CustratingReview.asp?Item=N82E16814102484) and NewEgg. That's worth something.

I've got a 9700 pro that I'll be getting rid of within a week or two. If an Orgah wants it, I'd be pleased to part with it at whatever is a good below-market price. It's probably worth a whopping $60 at this late date. But it might be a lifesaver for a strapped Orgah with an AGP system.

[gunslinger]

So, does anyone else have any info about the 9550?
