Oldr Thermaltake 480 psu with no 6 pin pci-e con. Video card options?

Hey guys, haven't posted in a while and am in needed of advice. I'm still using my older(okay old) Thermaltake 480 wat power supply that i got from 2004 :D :D . by the way my current setup is

1)Foxconn A74MX-K AM2+/AM2 AMD 740G Micro ATX AMD Motherboard
2)AMD Athlon II X2 250 Regor 3.0GHz Socket AM3 65W Dual-Core Processor
3) 4 gig ram
4)MSI R6670-MD1GD5 Radeon HD 6670 1GB 128-bit GDDR5 PCI Express 2.1
5) 500 gig sata hard drive and 80 gig IDE hard drive
6) Thermaltake Silent Purepower W0014RU 480W ATX12V Active PFC PSU

Here's the link to my power supply

Old power supply, I know but I've been getting all i can out of it. Can't believe i've been able to use an 8 year old power supply. As of right now the only other video card that doesn't need a 6 pin connector is Radeon hd 7750. I need to upgrade my video card a bit to help with 3d gameplaye for the minor games i play. But since i have no 6 pin connector it seems I'm stuck at the ASUS EAH6670/DIS/1GD5 Radeon HD 6670 1GB 128-bit GDDR5 PCI Express 2.1 that Im thinking about buying. Here's the link.

It doesn't require a 6 pin connector. Now I know there are some other video cards that can run with a 480 watt psu, LIke the radeon hd 6770(needs 450 watt) and the radeon 7770( some need 400 wats like this one
http://www.newegg.com/Product/Product.aspx?Item=N82E16814202011

and others 450) but they all require a 6 pin connection.
I know i can buy a 6 pin adapter but is that something i can try for my current power supply?? I'm trying to put off buying a new psu till later next year and am trying to push it further to last.
So, should i just stick with the 7750 with no 6 pin connector needed or could i try to use a 6 pin connector adapter for my current psu??

Buy the way, i have to stick with AMD cause i'm using my projector AMD HD3D

  1. Be careful of which Radeon HD 7750 card you get.

    There are Radeon HD 7750 900 MHz Edition cards that do require one 75W 6-pin PCI Express power connector.

    The Radeon HD 7750 performs much (1.47X) better than the Radeon HD 6670 and even uses less power than the Radeon HD 6670.
  2. cool, but how about the problem of not having a 6 pin pci-e cord on the my psu?? Would it work using the 6 pin adapter which attaches to 2 of the 4 pin connections on my current PSU?? I know you have to watch out for what amps your psu puts out for the video card but I'm not really sure how many amps my current PSU puts out and how much is needed for instance a video card. If i did get the 7750 card it would be one of these that run,

    880 mhz

    or this one that runs at 900 mhz

    Neither of those two Radeon HD 7750 graphics cards requires a 6-pin PCI Express power connector.

    Your power supply's +12V rail had a maximum output current of 18 Amps when it was new but after 8 years it'll be less.

    The Radeon HD 7750 will draw approximately 3 to 4 Amps from the +12V rail during gaming. It will all be drawn through the +12V power lines of the PCI-E x16 graphics card slot.
  4. Okay, thats cool about the 7750. But If i did want to try and run a video card that needed a 6 pin connector, like the this 7770 Here.

    It says it only needs a minimum of 400 watts but needs a 6 pin connector. Would this:

    6 pin adapter hooked up to my PSU be able to pull it off?? Wanted to know if that is safe to try with my PSU.
  5. There's no guarantee that it will work. The only thing you can do is to try it.

    Total Power Supply Wattage is NOT the crucial factor in determining whether the power supply is capable of powering your system configuration!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated @ 45°C-50°C ambient temperature, is the most critical factor.

    You may find power supplies on the market that supply more than enough Wattage to run the system. However, many of them lack the Amperage capacity on the critical +12 Volt rail, which is necessary to properly power the critical components in the system (i.e. CPU and GPU(s)). This is the reason why graphics card manufacturers overstate the power supply wattage, usually by at least 50 Watts, to take into account those power supplies that have the weaker +12 Volt rail(s).
