So after some discussion I have decided to upgrade my Geforce 8500gt to a Sapphire AMD 7770. I will also be adding 2 more gigs of 667mhz ram since that is what is currently in my system and I think that is all my CPU can handle as far as RAM speed (not sure on this just guessing can't find the info anywhere).
All that being said here is the specs of my computer I am wondering what PSU will fit my system. I am just looking for something that will power the AMD 7770. This is likely the last upgrade I will ever be making on this system so I do not need some insane PSU just something inexpensive that will get the job done for a year or two
- GeForce 8500GT
- Core 2 Quad Q6600 (K) (2.4GHz /1066 MHz) 8 MB L2 cache; Quad Core
- 2 GB (2 x 1 GB) DDR2 PC2-5300 with a max of 4 GB* (4 x 1 GB) (32-bit OS) available
- 750 GB 7200 rpm SATA 3G (3.0 Gb/sec)
- Windows Vista Home Premium
Any recommendations would be fantastic. I know that I need a 1 x 6pin PCI-E connector for the card. I also know that my current power supply is a 350w with 2 +12v @18A rails. Not that sure if all that will matter with a new supply buy that is what I know about it!
Any guidance on compatible upgrades would be fantastic. Again I am not looking to spend tons of money but a couple hundred would be ok. Thanks for any advice in advance!
Yes some graphics cards requires a higher amp to function properly. Basically these days, you dont really go by wattage anymore, you go by amps. However as you can see, the 550w delivers a whopping 44 amps so there's plenty for your entire rig and then some.
+1 For xfx pro series. Single rail means that the CPU, GPU and the rest of the components will be drawing all their power from the same rail as opposed to two different rails (some amps are not delivered on the 12v rails thus PSU's say -0.8 amps and such) Single rail is better. In the process of saving up for a 450w one myself. Btw i dont think you should be upgrading the ram on that thing. For the price of the DDR2 Ram alone you'll be able to purchase a decent processor such as the Pentium G620 which is comparable to what you have now and paves the way for future upgrades. I would NOT invest more in that system.. Your call.
