Upgrading video card need help

[lowep]

I have plans to upgrade my desktop with either a gtx 650 or a gtx 660 and would like to know if my computer can handle it and if it can then what power supply i should get to go along with the card. Here are the specs it is a cheapy I bought about 3 months ago to tie me over till I could build my own. http://h20000.www2.hp.com/bizsuppor...portFAQ&prodSeriesId=5187028&prodTypeId=12454

All help would be greatly appreciated

You might not need a new power supply. The GTX 660 has a 140 Watt TDP and your computer has a 300 Watt PSU. Your CPU is only 100 Watt TDP, so 100+140=240 which will leave you with 60 Watts to run your peripherals.

I would suggest taking a look inside your case to ensure your PSU has a six pin PCI-E connector.

If it does you might be able to buy a GTX 660 without buying a new PSU and you can just buy that when you build your own rig.

Hope this was helpful to you

Would the six pin PCI-E connector be just hanging or would it be attached to something? I looked and didn't see a six pin anywhere. If this means I have to upgrade my PSU are there any suggestions I could get that wont ruin my motherboard. Thanks for the help

I thought I read that the 660 required a minimum of 450W. I probably read it wrong but thought I would throw it out there anyways.

660 specs say 140w but i would not trust an oem power supply. They barely have the power to run the system they ship with. Have a look here for tried and tested power supplies. http://www.overclockers.com/forums/showthread.php?t=589708

So which PCU should I get from the list that wont hurt my PC and is reasonably priced?

If you have a look at the 600+ range it should see you through for a few upgrades/years, and you will also be able to use it in your own build when you get round to it. Any of them PSU's will have the 6 pin power cable you need, unless its a gtx 660 ti which needs two 6 pin connectors. Most of the 600+ PSU's will have 2 so bear that in mind if you go for the 660 TI.

The Corsair CX series of PSUs are generally pretty highly regarded around here for how low-priced they are. You can get this one for $30 after a promo code and mail in rebate.

Cheap as chips, jump on it.

Ok I will probably buy that PSU. Im thinking of going with a 560Ti instead due to a lower budget atm. Thanks for the help everyone

I wouldn't bother buying last years line up... Well actually that depends on what you plan on doing with your build.

What games and what res you play at. It's a relative thing
