Ay OCN! biggrin.gif

Alright- so here's the dealio. I've got a 3930K on a RIVE-BE plus two R9-290X's. I'll be using them for folding, mining, and gaming. Within the next week, I might have the chance to get a third 290X, already with a water block installed.

As of now, I have a Silverstone Strider ST-1000G that's had work done to the cables. I'm fully aware that it's more than capable of powering the Sandy-E chip and both Hawaii cards, but could it swing three 290X's? I could swap out the 1000W unit for the bigger 1200W that Silverstone offers.

Thoughts?

Why does it have to be a Silverstone PSU?

 

Anyway, since  you're going to have a constant 24/7 full load from Folding and Mining, you need to have a 1500W or 1600W PSU in order to maximize your efficiency and the life of the PSU. Otherwise, you're going to have the power draw being much too close to the PSU's continuous limit 24/7 (notice that I didn't say its peak limit) and that will result in a lower efficiency and a reduced PSU life. It's just too hard on the PSU. If all you were doing is gaming, then yeah a good 1200W PSU would be ok (but not a good 1000W PSU because that won't be enough), but not for Folding and Mining. Not at all.

 

So unfortunately, this will cost you $350-400. If you can afford $400, then I sincerely recommend the 1600W LEPA G Series.

It's a computer!

I'd prefer to keep it Silverstone so I can use the cables I had made by Lutro0. I've been advised to look into the Zeus series, although I've never seen a lot about them. It's a 1350W unit, but silver rated which admittedly isn't a gigantic difference, but a difference nonetheless.

I have 3x290x and a 4560k.
Underload draws about 850watts

I would save the trouble and stay with the 1kw

The 3930K can easily pull ~325W when overclocked.

I won't be pushing it within an inch of it's life mate thumb.gif most likely settle for around 4GHz just to keep everything cooler and stable (assuming my memory agrees with my CPU).

Hmm. I would still recommend a good 1500W PSU because you're going to have a constant full load (24/7) of at least 1000W. That's 67% of the capacity of a 1500W PSU, and that's in the sweet spot for maximum efficiency. If you weren't looking at Folding or Mining, then you could go with a good 1200W PSU and be safe.

Not all three cards will be active at the same time, two will be active 100% of the time and the other will be strictly for gaming (for maybe an hour or two a day). I mean I couldn't do it with my current PSU because it only has 4 PCI-E connectors, and the 1200 variation doesn't have any more. My only Silverstone option would be the Zeus 1350W which is a little rough as is.

Thanks for the advice guys smile.gif +Rep!

Again, I have no idea how much power he needs, but as long as he is getting a top quality unit one rated for the amount he needs should be perfectly fine, no need to get one that provides way more power then his system draws. I say this as a long term folder who has systems that have been running for years close to their rated capacity and never had a problem.

No, no, no. He will have a full load going 24/7. You do not want to be pulling 1000W out of a 1000W PSU 24/7 for weeks or months on end. Your average efficiency will suck and the PSU's life will be shortened quite a bit.

 

Even if all he were doing is gaming and his gaming power draw were 1000W, you would STILL not want to use a 1000W PSU. You would be better off with an 1100-1200W PSU.
