Power supply suggestions to accommodate graphics card!

Wouzer93 · Apr 16, 2014

Hi, as you know from the description I am looking for a power supply. Here Is my graphics card Asus GTX 770 Nvidia GeForce DirectCU II OC 2GB GDDR5 Graphics Card (PCI Express 3.0, HDMI, DVI-I, DVI-D, Display Port, 256 Bit, 3D Vision Ready, GPU B.

This graphic card requires 600W.

Here is my PC specs http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay?javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken&javax.portlet.prp_ba847bafb2a2d782fcbb0710b053ce01=wsrp-navigationalState%3DdocId%253Demr_na-c03030800-19%257CdocLocale%253D%257CcalledBy%253D&javax.portlet.tpst=ba847bafb2a2d782fcbb0710b053ce01&sp4ts.oid=5151854&ac.admitted=1397685945688.876444892.492883150

As you can see my pc also has a 600 w however after attempting to use my new graphics card I was unable to move from the hp boot screen. This to me seems to be a power supply problem.

So what I am asking is for someone to possibly suggest a power supply that could handle this graphics card and still fit in my case. There is not much room for maneuver on the current psu. If you can find one id be very grateful.

Hi, do you have any idea why I am unable to get off the hp boot screen then? Do I have to do the cd install I got before I change graphic cards so that when I do change it, it can work?.

may help rechecking cables inside the case without the power(unplug power cord).

did it worked before your replace gpu.

Yea the computer worked before with old graphics card, and then again after. The cables are all connected as I can see green lights instead of red when I opened the case.

nVidia recommends a minimum 600 W PSU in your PC; what you have linked shows UP TO what wattage the CARD itself draws from the PC. The 300 W is for the card itself - don't forget there are other components in the PC too.

Back to the OP:

Most of these branded PC systems (HP, Dell etc.) come with some no-brand PSUs and despite that it says it is 600 W it's probably not any better than a 450W PSU from a reputable brand.

I've been using a Corsair TX650 for the last 3 or so years and it's still going strong.

Any 650 W Bronze+ or better (Silver+, Gold+) from Corsair, BeQuiet, Seasonic etc. PSU would do. There are quite a few popular and reputable brands

Just pick one within your price range and do a quick google for it. You can find plenty of reviews nowadays for almost any piece of hardware.

Hi thanks for replying, I will check these psu's out, I was also doin some research and I read about how some graphics card can only run on certain bios and they said that the 760 was windows 8 bios. Have u ever heard of anything like that before? And if so is there anything I can do, if I have to start buying parts I might aswell build a new pc. ( even though I have no idea all the parts needed.)

It sounds like you might need a BIOS update. Your best shot is to open a ticket/post on the HP forums and ask for assistance asking them to give you a link for a BIOS update for your specific MotherBoard.

I would do that first before buying a new PSU by the way.

So after reading it looks like I will have to buy a new motherboard, is it as simple as replacing it or will other parts then need to be changed to accommodate etc, also is there anything I need to look for in a mother board other than the size so that it fits my case. Although a new case wouldn't be too bad as it isn't too expensive however, again would this affect any other parts I already have.

I would also like to ask, is it just the hard drive I need in order to keep all the programs I have on my desktop etc?

To be honest I am always on budget so always trying to salvage as many parts from my PC as possible.

First of all try and contact HP and ask them for a link for a BIOS update. I saw there some HP support rep giving links to people for their specific Motherboards. If they do not reply quickly enough for you (I am very impatient for example haha) then you will have to spent a few ££ (I'm guessing you are in UK).

Now if you wanted to save money all you need to buy on this stage (if HP doesn't give you a link with the BIOS update or the update didn't help) is to buy a new Motherboard. You can use the rest of your components.

Apart from the physical size of the new Motherboard you also need to make sure it supports your CPU.

The rest is just some fun taking the PC apart and installing the new Motherboard.

If you want to throw in a few more quid you could probably buy some aftermarket CPU cooler as you most probably have the stock cooler installed which is usually on the noisy side and not very efficient. But this is only optional.

Sorry forgot to answer about your Hard Drive question.

In general yes, all you have to do is to keep your Hard Drive, sadly when you install a new Motherboard you will have to re-install Windows so make a backup of all your important stuff on a separate hard drive or at least different partition of the hard drive.

If it's only documents, pictures, music you care for you can even transfer them to an USB memory stick and after re-installing your Operating System just transfer them back to your hard drive.

Hi,

Thanks for all the help, I am indeed from the uk. So therefore I will won't be replying anymore tonight after this. As you prbably know this is a gaming pc and I have a terribly slow internet connection, do you know of anyway that I could move my installed games from this onto the new motherboard, from what I know I think they are saved on the hard driver however I read that a new windows 7 or 8 would have to be installed meaning my programs would be removed.

Also if I'm understanding right, I am getting a new mother board because the current one is not uefi compatible and not because it isn't windows 8 like I read before.

Mouldread · Apr 16, 2014

Sorry for my delayed reply.

Well Windows 8 shouldn't be an issue with your current Motherboard nor with the new one. Your problem was we can't get passed BIOS. Operating system had little to do with anything in your case.

The problem we were trying to resolve was that your new Graphics Card was causing the PC not to start due to the compatibility issues with your Motherboard.

After buying and installing a new Motherboard you will have to re-install your Windows. I'm not sure if you keep your games installed on a separate hard drive or the same where Windows is installed.

If they were on separate hard drive most games would usually run with no problems if you hooked that hard drive to another system (or after windows re-install like your case). They won't appear as shortcuts anywhere but you can manually start them when you double click on their .exe file or you can create the shortcuts yourself.

If the games were Steam games (again on a separate hard drive) after Windows re-install all you have to do is to install Steam. Best way is to install Steam to the system hard drive and when you start Steam you can go to settings and give it the path to your "game library" pointing to the hard drive with the games.

If your games were installed on the same hard drive as your operating system then in order to save yourself the long downloading you will have to copy+paste them to another hard drive (if you have one of course). In general it's better to re-install the games after re-installing operating system but you can use the workaround I explained above. Unfortunately I can not guarantee all games would start this way though.
