Could I use this graphics card with my psu and connectors?

Last response: in Components

I was wondering if I could get any graphics card operating at all with my power supply. I'd like to go as high as possible in terms of performance, but my PSU seems to be limiting me on my options. So I think I'd be best off with an AMD GPU, because besides the high Price/performance ratio, it also has a high Perf./Wattage ratio. I was thinking of a HD 6870. I am not sure, but I believe that it runs at 168 Watts at full load. In any case, here is my PSU:

500W Switching power supply

+3.3V --> 20A
+5V --> 30A
+12V1 --> 16A
+12V2 --> 18A

It is a non-modular power supply, and all of the connectors are being used, except for:

- 3 Four pin Molex
- 1 Floppy connector
- 1 AC97 Audio (Don't think I needed to mention it)

My cables are all fully managed, and I do not have a blank check, so I really would like to get as much out of this power supply as I can before I upgrade wayyyy down the line. Will my three molex connectors be enough to power two 6-Pin PCIe connections? Does my power supply have enough amperage on the 12V rail? Are there any other combinations of adapters that could benefit me?

What is the make and model? That's not 500w, it's more like 390-400w.

Does it have any pci-e connectors?

What are you other computer components? cpu? mobo? hdd's? cards?

From the sound of it, I couldn't recommend anything more than a 7750.

It is some wierd, generic PSU called the 'Turbolink Switching Power Supply', and the model is the 'ATX-TL500W-BK'. It literally says nothing else, and there is not much information about it anywhere.

It has no pci-e connectors, and my PC has a DVDRW, two 92mm LED fans, Intel i5-2320, Asus H61 M-ATX motherboard, 4GB DDR3 RAM.

I'd recommend the 7770 because it only requires 1 pci-e connector. You can use 2-molex to adaptor for this, or the 7750 which requires no pci-e connector.

Get a 6850. It performs much better than a 7770, costs the same, and tops out at 125Watts.


Did you even read the post before responding??? 6850 is out of the question. :sleep:

Dude seriously, that's even worse than what you have.

If it doesn't even meet the basic 80+ efficiency rating, don't buy it.


80+ efficiency ratings are overpriced, why can't I just overkill on the wattage, but have a 75 efficiency? And how is this PSU any worse? It has more wattage, the same efficiency, claims to be XFire ready, and has 6+2 PCIe connectors. Most PSU calculators recommend ~430Watts, so it seems just a bit over the recommended.

Oh brother. A cheap 600w psu does not put out 600w, maybe only 400w.

Have you ever seen cheap speakers that say 1000w, but really would blow if you tried to give them 100w, yeah same deal.

The psu is the most important part of a computer. You get what you pay for. Just reading the reviews would scare the hell out of me.
