Guide for Selecting a Power Supply

[Big_Dave]

Hi thejackel,

I see your frustration with the situation.  I don't know if anyone out here has modified a PSU to work with the power connectors that are required by the motherboard in your PC.  I am not saying that it's impossible but it would take some research.

There are some mid-range full height PCI-E video cards that will work with a 300 watt power supply.  Do you have the 320 watt power supply in your PC?  What is the exact HP product number for your PC?

You do have 21 days to return the PC.

$130-->NVIDIA GT 545 43 GB/s -- single slot width ---- might be hard to find but perhaps only in the store

$80 at Tiger Direct -->NVIDIA GT 240 54.4 BG/s  -- single slot  --This card doesn't support DirectX 11 which is optionally used in some of the newer PC games but it is an excellent performer.

Review the NVIDIA performance specifications. Look at the memory bandwidth specifications and the DirectX level support.

You may not need that plug at all from what I'm reading.

I have an HP a6750t any ideas what type of power supply box I need. Not very good with this, The current one is 300 watts, and measure's 5.5L 6W 3.5 H. I would like to get something between 550 and 700 watts. As well as a good brand so its something that will last.

Hi RenaultFan,

This Corsair CX600 is an excellent quality power supply and it will fit your PC.

Thanks

I got the box but I have no info on how to install this. I put it in, it had power but the screen remained black.

[RenaultFan]

It seems its not running because it doesn't have a P4 MB, is there anything I can do about that or do I have to send the box back.

One last thing, the one I am missing is to plug into the mother board.

It looks like this, the smaller on on the end.

Is that what I need?

Hi,

Most Corsair power supplies ship with an 8-pin connector that splits in half. Use half of this connector for the 4-pin EPS/ATX 12v connector on your motherboard.  That step should be in the manual under step B.

Thanks, I got a 4 pin converter and installed the PSu and it works but the new PSU had no difference in my games FPS, going to buy a new graphics card and hope that improves the FPS over my old one. Getting tired of spending money and nothing is working so hopefully the card will. Also the processor fan I got is a clip in rather then screw in and it won't clip in. Even took the motherboard out to get it to snap in and nothing. Anyone know of anything that I can use to install the new fan?
