Yeah, thats what i thought too, SS is ROCKSOLID. And i read about some fan noise problems about the gigabye? nvm that, but 2 fans >= IceQ, right? Thanks man,i'll give it a try. And one thing iforgot- SHOULD I wait for the 660ti? or get this instead?
Every HIS IceQ cooler I've had was quiet, but one non-IceQ I had was noisy. I was reading this morning in another thread some comments about noise complaints on a Gigabyte 2-fan card, so I would not automatically assume the GB will be quieter.
Seasonic makes solid PSUs, but I'm not sure I'd run a HD7850 on an older 350W model, as capacitor aging would have reduced its output some. Coming from a GT520, you would see an amazing improvement from a HD7770 or even a HD7750, either of which should safely run on your PSU.
its a solidpsu so if I were you I would try running the 7850 and if its not giving it enough power wait a little save some cash and buy a 450 watt or so...you can pick up a solid 450-500watt psu for like $40 bucks if you try hard enough (not seasonic solid but still a decent psu)
I wouldn't deliberately stress a PSU that hard, even a Seasonic. While it isn't likely to kill your parts if it dies the way a cheap one might, it still may die itself, leaving you with no system for a while.
"For a system using a reference clocked single Radeon HD 7850 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 24 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.
It's not the power supply's total wattage that determines whether or not it is sufficient. It's the power supply's combined +12 Volt continuous current rating.
What i was really pointing was that my PSu has te capibility for 25A, NEVER seen my processor over 60W, even in EXTREME 3dmark 11, where the usage was 100% on ALL cores. Idk, the TDP of the 7850 is amazing, and you guys SURE it cant handle it? Cause a lotta my friends say it will.
+12V rails are almost never additive. When multiple rails are used, generally each one is current-limited to some percentage of the total. Does yours list a 12V1+12V2 combined?
For example, you may have a 22A (264W) combined, of which up to 10A can be on +12V1, and up to 15A can be on +12V2, but the total is still limited to 22A, not 25A.
Well, looks like those rails ARE additive in this unit. According to http://forums.atomicmpc.com.au/index.php?showtopic=264 the HD7850 needs 122W running flat out. You've got a 95W CPU; it likely doesn't actually use anywhere near that, but just for grins say it does; that's 217W. With only one drive, and three fans, it looks like you're safe, BUT there's that capacitor aging factor I mentioned. With no aging, http://www.extreme.outervision.com/psucalculatorlite.js... suggests 318W is enough, but with 25% aging, it goes up to 385W.
Only you know how hot it has been around that PC, or how much it has been stressed. If it hasn't been too bad, you're probably good; after all it IS a Seasonic, likely good for at least 10%-15% more than what's on its label. I just hesitate to recommend something that may fail poorly, especially to someone who can't just rush out and buy replacement parts.
i ahve a SS350HS, the photo you showed IS correct. Its output at 12v1&2 IS 300W.
My system temp stays at about 35-40degrees, CPU at 70-75 under heavy load (BFBC2,BF3)and GPU (OC to 1GHz) stays at maybe 80degrees. the "systemtemp" parameter in hardwaremonitor is avg 35 deg. And jtt, even i was REALLY surprised, HOW!?!?!? LOLOL. I was asking the engineer advice on a new psu with6 pin connectors, and he pulled out TWO 8 pin PCIe connectors from THIS PSU. WTF right? YES, my point WAS 24 amps, not a dell 460w,lol. As i said, CPU in 3dmark11, 100% use MAX power draw was 63.2W. BF3 it gives me 40-55W, BC2- 45-50W.
The 12v raild are probably NOT worn out, since my current card is a GT 520, which is like 20W , LOLOLOLOLOL. Just to clarify, the "op" is ME,Right?
so neither of those pictures help they dont show us anything of importance...but at least we are clarified that you do have a 350watt seasonic psu with one 6 pin PCIe power cord......that being said I personally feel that it will be enough to power a 7850 an your cpu both at stock speeds...if you overclock anything it will def not be enough....the 350watts is stretching it.
