Is it safe? Card is a Sapphire dual-x R9 280X. It's rated to require 750W but I've heard a couple people running on a lot less than that. I know what can happen if the PSU isn't enough. I just want to know if anyone knows how much power this card actually draws?

I'm guessing Corsair is one of the safest routes? I always wanted to get one but they've been too expensive. Do you know anything about Cougar?

Man that sucks. Are there any overstated power supplies with 80 plus certification?
 


Cougar uses HEC/Compucase Enterprise as their main OEM (i.e. Original Equipment Manufacturer).

HEC/Compucase PSUs have always suffered from poor ripple suppression. That's quite poor for a company that can't even come up with a solution when the majority of their competitors have no problem doing so.

Cougar uses Andyson as the OEM for their GX-S series but Andyson isn't considered to be much better than HEC/Compucase.

SR-71 posted a list of "bad" power supplies above, in that was NZXT. Not sure if it was as a whole or if it was a specific model. But I found the NZXT Hale90 v2 1200W and I really want it. It's a good alternative to the Corsair RM1000 from what I've seen. And it matches my case (NZXT Source 210 white). Would this be a good buy?
 


The NZXT Series that were to be avoided are the Hale82 N with all three models made by FSP. When the ambient temperature went above 35°C the PSU would produce electrical noise and ripple levels that were above what is allowed by ATX12V Power Supply Design specs.

The Hale90 v2 Series isn't afflicted with that problem.

I would still recommend choosing a Seasonic X-1250 or XFX P1-1250-BEFX over the NZXT Hale90 v2 1200W because of their higher quality electrical performance.

So yes, you would recommend this for mining? I saw it and just thought by your post that you meant all NZXT stuff because you listed specific thermaltake models.

Well, that Seasonic is expensive! And out of stock on Newegg. Would I really even be able to tell the difference in performance? If I can trust the NZXT to work, I'll go with it. Because of it matching my case, and also being in stock. And a little cheaper. I think I'll be looking at a new PSU, motherboard and CPU at the same time in a couple weeks with about $400, maybe a little more.
