I understand your concern though, I personally will mine with 2 gpus once I get my new parts...but will replace my psu since I hate the cables it has, and go for a bigger unit for benching.
I was addressing the budget conscious miner, who's building a dedicated miner with my posts. I'd rather go with an xfx psu personally, or the ax1200 biggrin.gif, whatever's good and single rail.

I've got a Seasonic X-1050, currently mining from 2 7950's. 2 more will be added once my riser's arrive in the mail. That p/s can handle a 5th card if I want it to. But that would be pushing it right to the limit. I can run 6 on my motherboard with using risers, but that would require a bigger p/s

Single rail psu's are overrated (no pun intended).

It's just a convenience feature for the person building the system. It does nothing to improve the performance of the psu. In some cases it can hurt the overall performance/quality. Because it's easier for the manufacturer to make 4 high quality 20A rails, than it is to make a single 80A rail.

Coming from people who bench, single rail is a must when you're really pushing it. And I don't buy crappy psus anyway. thumb.gif

Thanks for the discussion on all sides. I've been looking for a $60 or less PSU that can support 2 cards really, I have 2 x 6950's at the moment (can only use 1 until I get a psu) but could be anything else in the future. I figured that XFX may be a bit shy for running 3 cards but wasn't sure.

It seems it could, but by the time I upgraded anything it would be old, and I might as well just buy a cheaper, solid psu now, and another psu later If I need anything extra.

The mining rig has a cheapo 650w Ultra unit on it now, no way I'm putting 2 cards on it lol. Probably realistically comparable to a good 400w unit as far as output...

Not even comparable, since it may burn down either way...

Get a good psu asap! XFX are all seasonic inside, so can't go wrong.
Get 850w for 2 cards and regular usage, the 6950s draw 250w each, at stock.

Yeah XFX, Seasonic, and *some* Rosewill PSU's are really good.

For example my HIVE 750W is a Rosewill but I've heard it's actually a really great PSU. thumb.gif

I hope you guys are enjoying the DGC price surge! smile.gif

lol I love when people tell other people to take risks over the internet because it is very easy to sit in front if your PC and claim that the other person's PC will be just fine considering if it does create problems, well it's not really YOUR problem now is it? tough break, PC parts are prone to failure right?

yeah, I'd play it safe with the PSU, you know, the thing that affects every single other piece of hardware in your PC?

You are being quite paranoid, and aggresive with that comment man...Do you think I'm dumb or something?
Did you calculate power draw of the components while mining?

I think smart people will understand and agree with the points I made.
