What is the best GPU my 300w Delta PSU can run?

Hello everyone im new here. I did some research on what can my psu can handle when it comes down to gpu but im still not quite sure so i need some experts to ensure me if possible :)

This is my pc specs :

Cpu: Intel Core 2 Quad q6700 overclocked to 3.0ghz ( it was 2.66 without oc )

Ram : 4 gb kingston

Motherboard : MSI MS-7379

GPU : asus geforce 210 (1gb en 210 silent version)

I don't want to buy a new psu but if i have to i can. Cards that im looking to buy is 7770 or 7750 but i would prefer a nvidia card that gives as much performance as 7770 and/or 7750 if theres any. I'll be doing light gaming on a 1440x900 display . Thanks in advance for any replies.

More about what 300w delta
  1. Sorry i forgot to give my psu model it is a Delta GPS 300AB B REV 00F .
    It says +12V1&+12V2 : 19A
  2. Go for the 7750. Only about ~65 watt power draw, and beats any nvidia card power/performance wise at that price point. The 7770 requires a PCI-E connector, which I don't think you have. I would also recommend un overclocking your CPU, it won't botteneck a 7750, and with that PSU, less is better.
  3. thanks for the reply. i have 150$ ready to be spend but i can boost that budget to 200$ if i'll wait for another week or so. So can you recommend any psu + graphic card with that budget? or should i just buy 7750. un overclocking is not a problem. And also i have a small question my mobo has pci-e x16 slot for gpu. I know pci-e is backwards compatible but will i get any performance drop?
  4. Do you live in the United States? that way we can let you know where to buy
  5. Get a new PSU Corsair CX430 $45 shipped $35 after MIR

    Get a new GPU Sapphire Vapor-X 7770 $135 shipped $120 after MIR

    Both upgrades will benefit your PC. The 7770 just got a 5% performance increase with the release of Catalyst 12.11 and the Vapor-X overclocks like a champ while staying very cool. The CX430 will handle any other upgrades you can throw at it until you get above i5 & 7850 status.
  6. I recommend the Antec VP 450 for 35.99 (no rebates)

    and the HIS Icooler HD 7770 GHZ edition 120 after rebate as well.

  7. Thanks dscudella those are very helpful.

    Azteck, I don't live in USA but i can buy them from a USA site and give my father's adress.He lives in USA and comes to where i live once a month so he can bring them with him.
  8. PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027
    GPU #1: http://www.newegg.com/Product/Product.aspx?Item=N82E16814131477
    GPU #2: http://www.newegg.com/Product/Product.aspx?Item=N82E16814202004

    The power supply allows you to step up to mid-range gpu territory, which is gpu #2, but it'll cost you 210$ total (including rebates). If you can squeeze the budget then you should definitely go for it.
  9. Socialfox, Thanks for the advice.

    Doron, 210$ won't be too much of a problem so i'll look into it. Thanks for the advice.
  10. Three very good replies right there. Three different price ranges.

    PSU CX430 < VP-450 < CX500
    GPU PowerColor 7770 < HiS 7770 < Vapor-X 7770 < 7850

    The Vapor-X is the flagship 7770 and for that price can't be beat. The 7850 is a big boost over the 7770 but I don't know if you fit it into your budget.
  11. I'll be building a custom gaming pc in next year so i'm looking to save as much as i can so i'm just looking for a little upgrade that would benefit me until i built a new system.210 is not that big of a deal but i'm not sure if it is needed cause of the fact that i'll only use it max of 6 months. So i think ill go with vapor x and cx 430. Thanks everyone looks like this site is great for upgrading tips.
