Does a BTX case require a BTX power supply?

[Medellon]

I was given a new Gateway computer that uses a BTX motherboard and case design. I want to upgrade the graphics and need a new power supply. Do I need a BTX power supply or will an ATX one work?

BTX uses the same power supply standard as ATX.

What graphics card? Your current PSU may be fine for it, as most OEM's understate their PSU's. I've had a 512MB X1900 XTX running fine with a Dell PSU stated at 375W.

I currently have a 300W power supply that does not have a PCI-E power line. I want to upgrade to a GeForce 7950GT.

For a video card like that, you may want to upgrade to a PSU that has PCI-E power connectors.

Agreed. That card will suck some major juice.

The 7950GT isn't particularly power hungry, but I'd definitely upgrade.

Just make sure the gateway will actually work with a new power supply.

Ha! Most! More like a select handful. 10 OEMs or so will rate their PSUs for less then they can actually put out.

BTW, your Dell PSU was probably OEMed by either Lite-On, Delta, or FSP. Depending on the age of the system, but those are all decent OEMs, actually FSP produces the least quality products.

If I understand, the BTX motherboards need a 24 pin connector. Some ATX power supplies have 20+4, but others have only 20. However, I think that you can get an adapter to convert them.

No, BTX is more of a case design and it only really helped Intel I am pretty sure Intel diched the idea now that they have the 65mm cores.
