Will my PSU support a LGA775 procesor?

[V00D00]

I have a P4 3.4ghz LGA775 processor, but I'm not sure if my power supply will support it.

It says you need a 24-pin power supply for the LGA775 processors, but I'm not sure what this means.

I have a Antec True430 power supply, 430 watts. Right now I have an Athlon XP 2500+, and the main big connector is 20 pins, and then there is a 4 pin connector hooked to the motherboard as well. It seems the new P4 motherboards have the 24 pin and the 4 pin connector. I thought maybe they went together, but I guess not. I have no idea. Someone help me!!

Will it support it? Anyone know?

PCI-express motherboards have a 24 pin standard to supply extra power to the PCI-e slots. AGP based boards use the 20 pin PSU/mobo connector.

I believe your Antec has a 20 pin connector. You can get a 20-to-24 pin adapter, but I'm not sure how well that'll work. Other than that, you would have to buy a new PSU.

I have an extra little 4 pin connector thing that I put in on my athlon xp motherboard. Not sure if that's the same thing or not though...

Actually, you can still use the old 20-pin ATX power supplies with the new PCIe Intel mobos. I got in on the Intel Retail Edge promo deal on a P4 550/915PBL combo, and according to the 915PBL manual you can simply use a standard ATX power connector by plugging it into the first 20 sockets of the 24 pin motherboard connector and leaving the last four empty. You are supposed to be fine so long as you also plug in the extra 4-pin 12V connector and the molex that supplies extra power to the PCIe slot (if you are running a graphics card that pluus more than 75W). I don't know if this is true with any other vendor's boards besides Intel, though.

She's only using an X300 for graphics, so it is not drawing a lot of power, but the 380W TruePower that came with the Sonata case I used works fine with the 3.4GHz processor. All the rails are nice and strong under load with little fluctuation. The only thing I'd check on your TruePower is the amps on the 12V rail. The Sonata I got had a newer revision of the TruePower 380S, which has 24A on the 12V rail instead of the 18A the first version had. As long as you have a decent amperage on the 12V rail you should be in business.

If you are going to be running a 3.8GHz chip with a 6800 Ultra, I might look into a 24-pin EPS PSU to be on the safe side, but if you are planning on getting a slower CPU and a midrange card like a 6600GT that has less power draw, you should be okay with what you have.

no, its not the same thing. LGA775 motherboards need that plus the 24 pin power connector.

Most LGA M/B's will support the standard 20 pin ATX power supplies. I have 3 LGA boards and those all do.
