Intel i7 Power requirements...

by dabrum / August 9, 2009 2:41 AM PDT

Alright, so I got my computer custom made, and the day after i order it, I read something about how power supplies are the #1 Most overlooked part of a custom comp.

I got the intel i7 and a 400w power supply, should that be enough, because now that I have the computer, it worked fine for the first week, and now in the past 12 hours of use, it has turned off instantly 3 times now, the first two times i was running many things and thought it might have been a little too much for the power supply, but the most recent time, it turned off right when i started it up after going to google...

Thanks in advance for the help...

Talked to the custom builder ???

Checked the system temps ?

What else is in the system...specifically what parts by mfg and part number are in the system ?

And as always... all power supplies are not equal.

if you do have dual hd 4650 cards

In reply to: specs

then i'd say the 400w power supply is probably too small.

The 400 Watt power supply is insufficient for those two GPUs

Oh, I didn't know that if it wasn't being used that it would still run, then I guess yeah, the other card is installed just not connected with the crossfire link that I cannot figure out how to intall for the life of me...

Even if you have no monitors connected ...the video

In reply to: Oh...

cards are still running and pulling power from the bus....that's why you're having a problem now.

Just make sure you get a good quality PSU...because like everything all 600 watt PSUs are not equal. The better ones use less electricity too.
