Need help with Gigabyte GA-P67A-UD3-B3 with i5-2500k, which power supply to get?

post #1 of 5
Thread Starter 
I just purchased the GA-P67A-UD3-B3 and i5-2500k and couldn't run it on my Antec 400w High Current Gamer. How much wattage would I need, and how would someone determine the wattage need of their mobo before purchase?

That psu should be fine for what you posted on it's own. What gpu do you intend to use? Unless it is something low end you might want to upgrade. I will find the guide for psu recommendations. Give me a sec.

Edit: Check this thread out. Phaedrus is the go to guy with PSU information.

Even if it was a GTX 580, I'd expect the system to turn on...In case you didn't pick it up, the majority of the power draw in most systems is from the graphics card (if using a higher-end one for gaming) and then the CPU. Motherboard, hard drive, RAM, peripherals, fans, etc. have fairly low power consumption in general. Hard drives use a couple dozen watts on spin up, but not after they've already started. That's generally not an issue unless you have many many hard drives.

Check all the connections. Do the paper clip test, bridging green/black wires on the motherboard 24-pin connector to jump the PSU and see if it turns on, etc.

It's either the power supply is DOA and you should return it, or there was an improper installation.

EDIT: OOPS. I misread the original post.

Like mikeaj said, double check all your connections. As a fairly experienced system build, I can say that on multiple occasions I have missed something when I wired up a pc (I've built about a dozen PCs in the last year). In fact I did this within the last week.

Funny thing, forgot to plug in the 2X4 atx, got that to boot, but then I installed my cpu cooler, plugged everything in accordance, and now it does not want to start ever. Might have to bring in to specialist. Don't know if it's my psu ( brand new, only 1-2 months) or power button.
