Need some PSU help

post #1 of 6
Thread Starter 
Hey guys, in need of some help. My Corsair HX850 in my main rig died on me last night. Was loading up BF3, and ran to the bathroom. When I came back, my PC had restarted itself. It didn't even get to windows before it shut down again, for good. I am almost positive that it is the PSU, as I took the Corsair and a backup Thermaltake and jumped both with a paper clip. The Thermaltake stayed on while the Corsair failed after a second. My question is this: my backup PSU is Thermaltake Toughpower W0178RU 850W ATX12V V2.2 / EPS12V V2.91 SLI Certified 80 PLUS Certified Modular Active PFC Power Supply. I have had some issues with this PSU with my main rig.

^ link to the specs

I bought this PSU years ago and it has 4 +12v rails. It ran an Athlon64 X2 6400+, 4GB DDR2, and SLi 8800 GTS 640, but it can not run my 2600k overclocked + SLi 480's, at least I haven't figured out how. I am not very clear how multiple 12v rails work; even though I read one of the articles here on OCN about single vs multiple. Is there any way to figure out how to seperate the 12v rails in my main rig to stably run the SLi cards? Is it possible?

My backup rig is capable of running BF3 on Ultra settings, but damn I miss my SSD. I apologize in advance if this is confusing, as I'm not sure how exactly to word my thoughts.

Thanks!

Edit: After checking the specs for all of the 480's I have, none of the Newegg pages cover the Amps, just the a single card requires a minimum of 600w PSU.

First off that's not a PSU you would want to run a 480 SLI setup on... it's a CWT PSHII, similar to the Corsair GS800 internally... it's not really an 850W PSU, more of a ~750W unit, and not a great one either.
RMA the HX and stick to a single 480 until you receive the replacement unit, or simply buy an new PSU.

Just rigged up the Thermaltake for temp use. Have my PC gutted and sprawled over my guest room. I'm probably just going to stick to my secondary PC for now anyways. Thanks!

I copied "CWT PSHII" into google and came across a page with a ton of Corsair PSU's. What's a CWT? Under OEM, there are several different models, including CWT, Seasonic, and Flextronics. What's the difference? Just OEM brands? According to http://www.realhardtechx.com/index_archivos/Page447.htm, that 850HX is also a CWT.

Those are the different OEMs Corsair uses for their different power supplies they sell. Most all just use stock or slightly-tweaked designs that the OEM already came up with on their own. CWT PSHII is decent but not amazing, used by Corsair, Thermaltake, and some others. The issue is that Thermaltake's rating is a little optimistic on that particular unit. CWT DSG used in the HX850 is better.
