PSU upgrade? Motherboard compatibility? GPU upgrade

Hey there, im looking to upgrade my desktop soon with an ASUS ATI 5770, OCZ 600 Watt ModXstream PSU.

Question1:
Would the PSU work with my motherboard ( the PSU is 1 x 20/24-pin ATX , i don't know if it will work? confused? :S )


Question 2:
Also, would my CPU bottlneck my GPU?


Question 3:
The motherboard is PCI X 16 v1.1..... would it work with the gpu? i think 2.0 has comptabile mode with 1.1... not sure.

  1. Hello and welcome to the forums
    1_Yes
    2_In almost all games no
    3_Yes,PCI-E 2.0 is backward compatible with 1.0
  2. You should be good to go, sir.
  3. Uh are these also compatible with my motherboard?

    EVGA GTX 460 and an Toughpower XT 875W PSU. i know my CPU, RAM and motherboard are bad but i am planning for a future build next year Q1 2011 and would like to re use my PSU and GPU.

    QUESTION 4:

    The PSU says it has an "Main Power Connector (24Pin) x 1" is my motherboard 24 pins? (tried googling but can't find it on intel site ) What if it isnt? is it still compatible?

    QUESTION 5:

    Thanks Maziar about the info; PCI express 2.0 cards like the GTX 460 has backwards compatibility with 1.1 but what is the decrease in performance? Would i be at a significant disadvantage?


    Thanks for your valuable time :D
  4. Your motherboard has a 24 pin main connector.. The PSU is apt to handle connections for a 20 pin main connector board also so nothing to worry about.. As for the PSU-GPU config, i'd recommend getting a GTX460 1GB along with a good 750W PSU such as the XFX 750W Black Edition or the Corsair HX 750W.. To talk about the differences between the pci-e x16 2.0 and pci-e x16 1.1 slots, the former carrier a higher bandwidth marking.. The current line of GPU's however rarely are able to flood the 1.1 slot bandwidth.. Thus it hardly results in a performance difference.. Your current CPU however is not so good to be used for serious gaming.. I wont use the term bottleneck here but the clock speed is less and you'll need to overclock for optimal results when using a card such as the GTX 460..

    Your motherboard has a 24 pin power connector, and you won't see a noticeable difference between PCI-E 2.0 and 1.1
