Hey folks. I have a Gateway with a P4 Lexington 2 mobo. I've tried to upgrade to an EVGA 7800gs agp vid card. For that I need atleast 400watts of 12v and a minimum of 18 amps. I have tried various PSU's from different man.s, but I can't get any of them to do anything but light up the power button. I would like to upgrade, but I'm obviously missing something somewhere. Any help or advice would be appreciated, especially if you've dealt with a Gateway desktop with a similar problem. TIA
the following are the general specs except for the vid card:

Some Gateway PSUs are non-standard, but what is your Gateway model please?

Does your computer look like this?

Because according to the case views:

That case doesn't look as if it uses a standard size power supply unit, though this may be down to the way the pictures have come out.

That is the case, but the problem isn't the size, but getting the actual power supply to run the computer. I have an Allied 400W PSU that fits just fine...it just doesn't work.

Oh okay. You have checked the 20/24-pin connection is secure and you've plugged in the 4pin connector too and also any separate connector that the graphics needs? (note: Some PSU units may have more than one 4pin block for the mainboard. If this is the case, use another one.) Failing this, you may have a duff power unit. If the minimum requirement is 400w, you may want to send it back for a bigger unit, preferably 500 or more. It may well be you don't have enough leeway if the card is sucking all the juice. Or failing that, its possible that the Gateway uses its own wiring system which renders any separate PSU unusable, but this is unlikely.

I can't find more than one additional 4 pin hook up. I have a PSU with 20 +4 pin hook up. The vid card will run on the 250W PSU that I have and everything boots up and runs. However, it doesn't provide the amps or watts to support any 3d graphics found in most games. I'm changing to the 400w so I don't blow the motherboard. I just can't, for the life of me, figure out why I can't get one of five different PSU's to work. Though the power button lights up when pushed, I don't even hear the fan turn on. I'm going to try a direct connection to the house's electrical outlet, rather than via surge protector. Then I'll trouble shoot from there and let you know. Thanks for your help so far.

This sounds like non-standard Gateway wiring has been used and the board is unique, therefore it will probably only work on that power supply due to the way its been made. If this is the case, all you can do is replace the board. No way can five different PSUs have the same fault and the board is the thing in common so it has to be a unique wiring issue.

What do you mean it oesn't supply the amps or watts to support 3d gaming? DOes that mean when you load a 3-D game it crashes? Or does it not load when you have the graphics card plugged in? YOu are more likely to damage your motherboard plugging in these other power supplies than over taxing a psu. Instead, it should either crash or not start up at all if the amps and wattage aren't enough. Often times, wattage amounts are over exagerated to keep people from buying garbage PSU's like PowMAX, RaidMAX, Allied, Deer (shudder), L&C etc. and wondering why their thing won't load and get angry at Nvidia/ATI. In reality is that these PSU's use over inflated numbers (if you look inside some from allied/raidmax/deer, the boards sometimes will say 400Watt and they advertise it as 750!!! :) ) I have seen too many computers killed by those brands to EVER trust them EVER!!!!!!!!!!!!!!!!
