I just installed a Corsair GS700 power supply into my HP p6710f desktop, replacing the stock Bestec 250w P.S.

So far so good, runs nicely, quiet.

Next (later today) I will be installing a GeForce GTS 450 1GB PCI-X video card (the reason I installed the new power supply).

Hi egkor,

How did you fit the 6.3" depth for GS 700 inside the HP p6710f case???

The standard PS depth for this case should be 5.5"?? I am curious to know that

Best regards

AOG,

My guess is that you can't get a piece of paper between the optical drive and the PSU.  I am just exaggerating some.

5.9" by 3.4" by 6.3".  The standard PSU is 5.9" by 3.4" by 5.5".  That probably makes it .8" longer.   The trick with the long PSUs is to slide the optical drive forward then install the PSU.  It makes it a lot easier.

I got the GeForce GTS 450 installed successfully w/ the GS 700 PS.  And video drivers/etc.  Using the system to post this.

The new PS is deeper than the original, but when installed there is still space between the back of the PS and the optical drive.

Edit:  I didn't have to move the optical drive, just out w/ the old PS and in w/ the new.

Hey Gary,

 Thanks for letting us know about your success with installing your 700 watt corsair power supply.

It looks like this brings the limit up to 700 watts that can be installled in an HP desktop and with this in mind I wish I had bought that model.

After having two failed attempts with the corsair tx750v2  http://www.newegg.com/Product/Product.aspx?Item=N82E16817139021 and then speaking to HP and them telling me 600 watts is the max I could install in an HP desktop I went ahead and got the budget model the corsair cx600. So far so good but I am definantly considering buying either your model or Big_Dave's model to have a little head room.

I am curious if this is truly a wattage compatibility  issue or if there is more to the difference between the GS700,cx600,hx650 compared to the tx750v2 model?, I am ignorant on power supplies and realy computer's in general to know the differences between them...all I know is I could not get the tx750v2 to work after trying two different brand new units.

Hi Gary,

Good show again!:smileyhappy:

Hi Tarpon,

Perhaps the newer and bigger PSUs are not providing a sensing voltage signal that is the same as the older power supplies.

Well that is interesting.

So in this case you ignored the latch that lock on the 5.5" which used to mount the PS correctly without movement

good for you, and good luck on the new upgrade

4 screws and the old PS came out.  The new one went in, 4 screws back in to hold it into place.  I didn't observe a latch, maybe I missed it.

I am actually surprised some of you are telling me I should have failed at this.  I guess since I didn't know that going in, I was able to get it done.

Thanks for posting the dimensions; not all mfg's tell us what they are.
