It also rests on a couple lower supports, then is held in place by a lever. I removed the bracket (two screws) to see if the PS would be stable without it. No go. So I can't easily swap out with a standard ATX PS. I don't see a practical way to attach the bracket to another PS - don't particularly like the idea of drilling holes into it. I also considered just swapping out the case, but that gets more complicated." And looking at the description, your computer has a P4 processor, which means it'll have the standard ATX12V 2x2 cable for powering the processor (two yellow wires and two black wires). (You can find pictures of a lot of the connectors here if you need them.) http://www.playtool.com/pages/psuconnectors/connectors.html I'd take the side off the computer, and verify that is how it fastens. On the computer cases I have here, when I want to change a standard ATX supply, there are four screws that go through the back of the computer case, and screw into four holes on the fan-switch-cord side of the power supply. But your Gateway 500s, seems to use slides and a bracket and a locking lever. Probably intended for the factory assembly line, to take less time putting in the supply or something. Now, this picture, on the other hand, looks smaller than an ATX. You can see there are screw holes on the top of it, to hold a bracket. Perhaps the bracket is an attempt to adapt a smaller supply for a computer case that holds a standard ATX ? http://www.memoryworld.com/servlet/the-94/Gateway-Power-Supply-500S/Detail ******* These are three documents I have copies of, that define ATX supplies. The 1.1 version still has -5V on it, but it is hard to tell whether computers of that era, actually have a need for -5V or not. They were supposed to stop using -5V, well before the 1.3 version of the ATX standard came out, but I probably have at least one computer here, that won't start unless a supply with a -5V wire on it, is connected. http://web.archive.org/web/20030424061333/http://www.formfactors.org/developer/specs/atx/ATX_ATX12V_PS_1_1.pdf http://www.formfactors.org/developer/specs/atx/ATX12V_1_3dg.pdf http://www.formfactors.org/developer/specs/ATX12V_PSDG_2_2_public_br2.pdf If I look at the "ATX_ATX12V_PS_1_1.pdf" spec for example, the dimensions of a standard ATX supply are listed on page 23. They're 86mm high and 150mm wide. I measured a dead ATX I have here, and got 3.39" high and 5.91" wide. The length (how far back in an ATX case the power supply goes), can vary somewhat, with the monster power supplies with very high outputs, being longer than others. On page 27 is a table of wire colors for the main connector. That is supposed to be a hint for what voltages are present on what pins. You want to verify those colors, to help you decide whether your supply is a standard ATX or not. ******* One problem with something of this age, is finding a picture of it that actually matches what you've got. There are any number of tricks they can use, to make the supply more difficult to replace with a standard one. The rating of your supply, 200W, is not a lot of power. If you look at the label, there should be ratings for each of the DC outputs. On a Pentium 4 processor based system, a typical desired rating might be 12V @ 15A for example. You don't want to go too much lower than that, without having a very good idea what the actual load is. Your new supply, should meet or exceed the maximum current ratings listed on the label of the current supply. Chances are, there will be enough wire assemblies on the new supply, to wire up the supply. You will likely have cables left over, which is fine. They don't need to be connected. It is also OK, to use a higher power supply, such as 350W, in place of a 200W supply. The wattage rating is the maximum output, rather than a constant level of power being output all the time. You can draw 100W from a 200W supply or from a 350W supply, and the power company will bill you for 100W. So the supply wattage rating is its maximum, rather than being an "all the time" kind of rating. The 350W is not "wasting" 150W more than the 200W one would have. The current supply will likely have a 20 pin connector. If there is a wire and pin for pin 18, that means the supply has -5V output on it. We don't know whether the computer needs that, or that is coincidence. Most modern supplies will have pin 18 (white wire) removed, and there would be no pin in that location. Another thing on modern supplies, is the main connector is 24 pins. Most supplies will have a provision to split the connector into two pieces. Such a connector is called a "20+4", because of the size of the two pieces. The 20 pin section, can be plugged into an older motherboard (you leave the other 4 pin bit dangling, and it never gets used in that case). That is an attempt at being backward compatible, with the least amount of trouble for the installer. By splitting a 20+4 connector, you can power older 20 pin motherboards like yours. So even the latest supply, can be used inside your case. Power supply selection can take seconds, or hours, depending on the vintage of the computer, and the things you read about it. Take your time, and do some more reading, before rushing off and buying something. If your supply does have some goofy mounting system, that isn't going to help matters. I can't recommend drilling holes into a new power supply, due to the danger of metal filings causing a short circuit inside the supply. In any case, have a look at it, for any details like that. By the way, that power supply part number could be NPS-200-pb rather than p6. It would appear there are quite a few different models of Newton brand supplies. The Gateway site may also have specs for the supply. Gateway has their own part numbers, which call up one of several equivalent supplies. This is just an example, rather than being for your supply. http://support.gateway.com/s/POWER/6500158/Q0015810.shtml The Gateway site, recommends a few sellers as sources of replacement parts. http://www.gateway.com/retail/accessories.php For example, this would be a page with some "500S" computer parts. Note that the supplies are keyed by Gateway part numbers, and the form factor is different on a couple of the entries. It's hard to believe they're all relevant for your computer. Take a look at the pictures and see what you think. The higher power ones are the same price as the lower power ones. I notice the supplies they're selling here, have a fan attached to the outside of the case, rather than having it mounted inside. http://www.skyline-eng.com/index.cfm?fuseaction=category.display&category_id=5324 Newegg.com carries plenty of power supplies, probably hundreds of them, but you'd have to carefully check all the details before using one of those.

I searched for over an hour for you and came to the conclusion: your computer does not exist. Not even on the Gateway site. No, actually, what few Gateway 500s models I could find had 160W power supplies, and the 500s model is difficult to find as it is. I found no matches on a general search, and on specific sites for a matching power supply came up blank. There were a few later 500-series models with 200W, but still difficult difficult to find and still without the specific matching power supply unit for your unit. I couldn't even find a site for Newton Power. Maybe one of the other guys can come up with it. Anyway, it's still probably a good idea to upgrade to a little bit higher wattage PSU in case you decide to add parts to your computer later. You might find something adequate at www.newegg.com They have 200W-250W PSUs ranging from $14.99 + $4.99 shipping - $27.99 + $9.20 shipping. REMEMBER: You have to know if your connectors are 24-pin, 20-pin, or 20-pin + 4-pin to select a PSU that will power your motherboard without adapters. I wouldn't go too high a wattage or price. --- news://freenews.netfront.net/ - complaints: news(a)netfront.net ---

Okay, so what do you think I should do for the power supply, as far as watts- 200w-250? What is good to be on the safe side . the current one says on the label 200w max... Now as far as the connectors...I dont know what they are all i can tell you is that I have a Intel (essex) Pent 4 - 1.8GHZ (400MHZ) motherboard.. So I dont know what the connectors are though. thanks KOS
