Can this PSU power a HD 6870?

Hello Guys!

I ordered a HD 6870 today and made a big mistake by cheaping out on the psu with an off-brand.

This is what I got with it: http://www.newegg.com/Product/Product.aspx?Item=N82E168... (Raidmax 630W)

I already know it wasn t the best decision but do you think it can safely power 1 6870?

It will probably work for a while, but that card will probably stress that psu, and I'll bet it fails within a year

I dont see how a single hd6870 will stress out a 630 watts PSU when that is plentiful no?

Thanks! I decided to cancel my order and spend a little more on a decent psu..better safe than sorry! I just read too many mixed reviews about raidmax products

What makes you think it can really output 600w+ droking?

My general rule of thumb in this day and age is to avoid any PSU with that little red switch in the back. Just put it down and walk away. At best its an old design that will cost you a lot of money, at worst its a bad design that will blow up and possibly take your system with it.

As for the question, I'm not sure. I guess I vote use it, but replace it ASAP. And don't OC anything.

it will work.
however any 550watt QUALITY PSU is enough to run any SINGLE graphics card.

For a system using a single Radeon HD 6870 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 30 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important.

The Raidmax Hybrid Series 630 Watt (RX-630SS), with its combined +12 Volt continuous current rating of 36 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is theoretically sufficient to power your system configuration with a single Radeon HD 6870.

Whether or not the PSU is able to supply the power specified on its label is another story. There's anecdotal evidence that seems to indicate it doesn't.

36A and 630? My 500W could do 34.

Exactly my thought.

But what's more the point is not whether it can power it, but can it power it safely and reliably over time? The answer to that question is a pretty certain "no". It'll work for a while probably. But eventually some of your parts will start breaking and you'll wonder why and eventually your system will start restarting randomly and you'll wonder why. And for most people with these symptoms, it's usually because of a bad PSU.

Yeah, that's what the 380W green goes for.
