550ti with a 500W PSU

[Jay9]

OK, so I'm looking into getting this: http://www.newegg.com/Product/Product.aspx?Item=N82E16814133431

On Newegg, it shows a minimum requirement of at least 400W. Now, I decided to check the one on PNY's official site and it's showing it as needing a 12v with a 24a rating.

The issue is, my PSU is a 500W, but the 12v rail only shows a 22a rating. Now will it be a system-crashing issue if I attempted to pair this card with my current PSU?

Was able to dig up the page for my PSU: http://www.directron.com/rx500s.html

You might have a problem, but I don't thnk so. According to guru3d, all you really need is a 400-450 watt power supply. So, even with amps slightly below the recommended, your watts are above the recommended.

I also forgot to mention the other things drawing power.

MB: MSI H67A-G43 (B3) LGA 1155

RAM: G.SKILL 4GB (2 x 2GB) 240-Pin DDR3

CPU: Intel Core i3-2100 Sandy Bridge 3.1GHz

x1 120mm cooling fan
x1 120mm LED cooling fan

x2 SATA drives

That's not bad at all.

It will work, but I'd replace that PSU ASAP. No 8pin motherboard power and has more floppy plugs then PCIe? Crazy. Also sad that as a "500W" PSU it only puts out 22A on the 12V rail. This makes is more like a 300W PSU. All thats missing to complete the sadness is the little red switch on the back.

I would get the HD 7750 for that PSU.

I have similar PSU like yours , But it's name is 3zone and it is made in Korea. ^^

It's only 400 watts and i run 6670 GDDR5 on it. HD 7750 is the highest GPU i can go without Upgrading my PSU

If you want GTX 550 ti or higher.. You better upgrade your PSU to a Quality one. Just for more headroom. Even if it's another 500watts but it has higher AMPS.

Assuming you know the mobo only has x2 PCIe x16 2.0 slots, you can install a 3.0 card into a 2.0 slot?

It is backward compatible. It will work even on 1.1.

 

[Jay9]

So, just for a final answer....

550 ti or 7750?

Cheapest as performance is so close. 7750 if power is a concern.

 

[Jay9]

Well... I keep getting so many mixed responses.

"Yes the 550 will work."
"The 550 sucks. The 7750 is better."
"The 7750 sucks, the 550 is better."
"The 550 won't work on that PSU."

But I guess I'll get the 7750 just to block out the power issue.
