Urgent: Does my PSU support the new CPU

[ravenjedmanicdao]

Hey guys, I am very close to upgrading my CPU, the package has almost arrived. I still have the very old sockets, 775. I have the crappy Pentium E5700 dual core that is too old, and about to upgrade it to the Core 2 Quad Q8400. I have a 300W PSU that are powering my components, I will state their power usages if I know them:

CPU: Pentium E5700 (65W usage)
GPU: GT 730 (38W usage, although overclocked)
Motherboard G41T-AD (Micro ATX)
HDD: Seagate Barracuda 1TB (5.9W, full load)
RAM: 4GB
x1 100mm case fan
x1 80mm CPU fan

I also have the optical drive, which is barely even used at all. Can I unplug it to get more power for the CPU? Please don't suggest other CPU's, I have made my decision already and the CPU is making its way to my mail. I just need to know if I can run it or not, thanks!

Don't really know anything about your PSU than your wattage, so can't say. The optical drive doesn't use much power, so if the PSU was insufficient, unplugging the optical drive won't change it.

As for your motherboard, this is an old motherboard for a pre-built without good documentation. It's a very open question whether you'll actually be able to run a 95W CPU at all on a board like this, regardless of the power supply.

Looks like DSzymborski has the right idea. This thread might enlighten further.

On top of this. It may make sense to look into a new system in general if this is what you're trying to do.

For your information, I am using a spare HP PSU 300W which is an OEM one, my other PSU's had broken down.

I would want more power for headroom but as we said it looks less like the psu is your issue and the mobo is more of the problem with what you are trying to do.

What are the chances of me being able to run it?

Also, do I not have enough power delivery for the core to run?

Your basic OEM PSU *probably* can squeeze out the performance. If you ever want to add a more powerful GPU, it'll be definitely be time for a real, quality PSU.

As for running on the board, without documentation, it's really a coin flip. A basic, entry-level motherboard for prebuilt emachines and Acers that was running a lower wattage CPU? You might be fine, but I wouldn't bet *too* much on it.
