Hi, I have a HP Pavilion a6700z. with this PSU in it http://www.censuspc.com/300W-ATX0300D5WC-ATX-Power-Supply-for-HP-Pavilion-P6330F--HP-P6210F--HP-585008-001-Model--ATX0300D5WC-pr-11669.html
The CPU is a AMD phenom II x4 955bc. I have 5120GB DDR2 ram.
What i'm asking is what kind of PSU will FIT in the case? I don't want to buy a PSU and it wont fit. If anyone can plz link me a PSU that will fit. and if possible a GFX card to. I really dont want to upgrade the PSU if i have to. Plus i am looking for a place that sells them in a combo deal. Can't really spend no more than $150. I have 2 hard drives and have a DVD drive and CD drive and card reader built in.

THANKS!

It's hard to know for sure what's compatible with a pre-built system as they tend to have custom parts built specifically for the manufacturer

Here's what I came up with for you.

GPU: http://www.newegg.com/Product/Product.aspx?Item=N82E16814121632R @ $103.99
PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817171031 @ $39.99


*IMPORTANT* The GPU I listed is a dual slot video card, meaning to takes up two slots on your motherboard, please be sure that you have sufficent space BEFORE purchasing.

This should just fit into your budget and leave a few dollars spare to help cover shipping and postage.

I hope this helps.

That page gives no information about mounting support for a PSU.

There is almost no way to tell, but honestly, you would have to be pretty damn unlucky to have any trouble fitting a PSU in any case anyways, it's a safe bet that you will be fine.

That's called a Mini-Tower case. It only handles micro-ATX form factor motherboards.

The power supply form factor is ATX (a.k.a. PS2). The standard physical dimensions are 5.9"W x 3.4"H x 5.5"D. The depth is the only specification that is allowed to be different. Higher power PSUs will have a larger depth and you will need to check if there is enough clearance between the back of the existing PSU and the optical drive(s) to be able to fit a deeper PSU if that is what you buy.

If you want to upgrade the PSU anyway I have installed the following PSU into an HP Pavilion Mini-Tower case exactly like yours and have had no problems with fit or compatibility:

If you don`t want to upgrade the PSU then the best card you can currently buy that doesn't require any PCI Express supplementary power connectors is the Radeon HD 7750.

Make sure you know what your buying because there are some Radeon HD 7750 900 MHz Edition cards that require a PCI Express supplementary power connector from the PSU.

The ASUS HD7750-T-1GD5 is an example of a 900MHz card that doesn't require a PCI Express supplementary power connector:

I just looked at my PSU it s ATX0300D5WC Rev. A. I linked a rev. B its an A. So i can run a GFX card on a 300 watt PSU with no problems? Or is it going to bottleneck or ruin the psu within few months? With all the stuff i have hooked up not sure if i have wattage left over to use one. Plus i was looking inside the PC from what it looks like theres no room for a GFX card to fit because all the dang cables in the way. I can use a PCI Express 3.0 if the board is a 2.0?

For a system using a single Radeon HD 7750 graphics card AMD specifies a minimum of a 400 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 20 Amps or greater. This +12 Volt continuous current rating is based on a reference PC configured with an Intel Core i7-3930K 3.2GHz 130 Watt TDP processor. Your system consumes a lot less power than the reference system used by the graphics card manufacturers. For your system a maximum combined +12 Volt continuous current rating of 15 Amps or greater is more realistic.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

The HP OEM Bestec ATX0300D5WC Rev: A power supply, with its maximum combined +12 Volt continuous current rating of 19 Amps, is sufficient to power your system configuration with a single Radeon HD 7750 graphics card.

A graphics card based on the PCI Express 3.0 bus will have full backward compatibility with a motherboard that uses the PCI Express 2.0 bus.

An AMD reference design Radeon HD 7750 graphics card is only 6.65 inches (16.9 cm) in length. It should have no problem fitting into your PC case.

You can open up your PC case and take measurements before you purchase to confirm that it'll fit.

OK i was tryn to figure out why CPU was running at 803mhz its a AMD phenom II x4 955bc and the board is a ASUS M2N68-LA narra3. Why is that? Is it bad? If it is what kind of CPU can i get for the board that is GOOD!?

I don't think the M2N68-LA (Narra3)'s BIOS officially supports your Processor model.

It may only be idling at 803 MHz.

Try placing the CPU under full load (i.e. use Prime95 or some other CPU stress testing utility) and then check to see if its Core Speed rises to 3200 MHz.
