You will be fine. My rig with a 5850 and a quad core draws 290w at the wall.

For a single 5830 you should be fine with 450W, it's not a particularly hungry card.

Having said that, if you want a better PSU that won't cost the Earth, check out the XFX Pro 650W Core Edition.

I also don't recommend buying used PSU. The PSU is the most important part of your rig, bar none.

Corsair is great.
I personally would not buy a used psu, because their lifespan is estimated for certain amount of hours and you never know how long it's been used for and at what load.

Ok, thanks. Glad I checked now.

I'm also watching a Corsair 650TX on eBay like this:

Maybe that would be better?

Alternatively there is a lightly used one of these on eBay for £25 ($40)

Anyone want to offer an opinion on this PSU?

Thanks

That's exactly the one my friend blew in two hours, except it was 1050W Grin

Don't buy PowerCool

Like phantastisch said - it totally depends on the brand. The amount of power you have is plenty. I was mining on a 5870 with a 250W for about a week until I got round to buying a better one Grin

while my friend blew a 1000W brandless psu within couple of hours mining with 2x 5870

I can't remember the brand. I was going to write down the details and the power ratings before I left home this morning but I forgot Sad

It's not a top brand but it's also not the cheapest one I could lay my hands on. I had to replace the original PSU in the machine I build after I blew it when I was swapping things around some time back.

If you'r managing to power 2 x GPU's then i'm guessing I should be safe with one.

Hi All,

I have a question (my first, but probably not my last

) ...

Having recieved the XFX Radeon GD 5830 I ordered a couple of days ago I'm now wondering if my power supply is going to cope? My machine is a P4 3.2Ghz with a 450W power supply which has 4 x 4 pin molex connectors for peripherals.

I'm looking guidance on whether I will be able to use the two, dual 4 pin to 6 pin adaptors to power the GPU, which will take up all 4 connectors available from the power supply, and also power my HDD using a splitter?

Thanks
Monkey
