Solved Compatible CPU and PSU suggestion for my Intel Motherboard

January 26, 2015 at 08:30:44
Specs: Windows XP
My machine spec is-

Mobo- Intel D945GCNL (With PCIe x16)
Processor- Intel Core 2 Duo E4500 2.20GHz/2M/800
RAM: 1 GB DDR2 PC667

I am currently running with integrated onboard graphics unit but would like to move on to a Medium-Good Graphics card. Also I read that a GPU and Mobo has a lot to match with the PSU. So which specs should I look for to buy PSU and GPU?? Within a low to standard budget in India?

Many thanks in advance :)

As I stated, 1 12V rail is preferable. The wattage can be deceiving. You need to add up the total Amps required and use a power supply with more capacity than that.

The Radeon 6670 is a low consumption card. The link below shows TOTAL system consumption at about 12A on the 12V rail.

Look at your current power supply to see what the 12V rating is. You may be able to keep your current power supply. Do not go by wattage for the whole supply. The 12V rail is the important one in modern systems.

Almost all PSUs available in India are junk.

Motherboard doesn't draw much power. The CPU draws 65W max. Most of that will come from the +12V rail. That comes out to about 5.5A@12V.

The graphics card can draw quite a bit of power. Again, most off the +12V rail. So you need to choose a card.

See the table in the link below. Add the 5.5A for the CPU to about another 5 to 10A@+12V for the board, RAM drives, etc, Then add the Amps from the chart to that total to arrive at the needed Amps@12V. At some more for power supply waste.

Post the brands and models of any power supply you have available for help choosing the best of the junk. If there are no detailed specs for each rail then don't even consider it. Also, you should get a PSU with ONLY 1 +12V rail, not multiple.

Here's your motherboard specs: http://ark.intel.com/products/50369...

What are you hoping to accomplish? You need more RAM. Unfortunately your board only supports up to 2GB. Even so, you should install the max before doing anything else.

You didn't post any PSU info so it's impossible to say if it's in need of upgrading or not.

Just about any graphics card you get will be better than the Intel IGP. If you're just looking for a cheap all-purpose card, look for a nvidia Geforce 210 or Radeon HD 5450. Both cards have very low power requirements so your current PSU probably won't even need to be changed.

Actually I am running my PC with a 230W PSU (a local brand) but I'm afraid I need to get a PSU with more wattage to run a good graphics card(My need is to play games of say 2012, not really hardcore). Having read a lot of reviews, I am thinking to go for Radeon 6670 DDR5 (1GB). So if I upgrade to a 2Gb ddr2 ram (since the board only supports upto it) and get a PSU of above 400W..should it be okay? Also, do I need to check for two 12v-s while buying the PSU or only one will do good?

And please let me know if there's any way to get out of the 2GB RAM limit... And another graphics card model in case I have to choose other than 6670. Thanks a ton. :)

Ok that's definitely a great info. I will check that once I reach home and then think about getting a new PSU. And so far I am going to buy the 6670 soon, so I guess no problem with that card. Thanks! :)

So I checked....and my psu says the 12V line (+12VDC has 11A/25A) written in the sticker attached to it. Is it safe to go? The Radeon 6670 is a low power consuming card so...should it be enough?
