HD 6850 power question Tags: Radeon Graphics Product Last response: August 30, 2012 7:34 AM in Graphics & Displays Share darkenergy95 August 28, 2012 10:17:21 PM I'm building a computer at the moment and I'm having some dilemmas. Specs: Gigabyte H67MA UD2H B3 i5 2310 @ 2.9GHz 16GB DDR3 Corsair Vengeance ASUS HD6850 DCU & MSI R6850 so far.. Now , the main problem is the PSU. 1. The motherboard has a 8 pin connector for the CPU. 2. The graphics cards need one 6 pin connector each 3. The recommend power supply wattage for crossfire is 650w So with that known, I went searching for a 700w power supply and found this: http://www.thermaltake.com/products-model.aspx?id=C_000... But it says : Output Capacity 600W / 500W Max. Output Capacity 700W / 600W What does this mean? More about : 6850 power question Deemo13 August 28, 2012 10:24:39 PM I wouldn't go with Thermaltake. There are much much better options. The Corsair CX600 should do well: http://www.newegg.com/Product/Product.aspx?Item=N82E168... m 0 l darkenergy95 August 28, 2012 10:29:13 PM Really? Its only 600w though.. m 0 l Related resources Upgrade my Power Color HD 6850 - Forum Upgrade from Power Color 1GB Radeon HD 6850 (~$250 budget) - Forum Question about AMD Radeon HD 6850 - Forum Upgrading my hd 6850 question - Forum Radeon HD 6850 with CoolerMaster eXtreme Power Plus 500W - Forum Can't find your answer ? Ask ! Get the answer GreenDutchAlien August 28, 2012 10:37:20 PM Yes, but it's a REAL 600W. A lot of less quality psu's overstate their actual power and can't deliver what they promise. Also it's important to have a psu which is stable, meaning it doesn't have all kind of distortions and ripples. m 0 l darkenergy95 August 28, 2012 10:42:05 PM Ah I see , I am on a budget though so I need a power supply with some bang for buck. m 0 l Deemo13 August 28, 2012 10:50:01 PM Well, the power supply is pretty much the one place you dont want to skimp. And you do have 2 cards. That 600W is probably the lowest I would go to run that setup. This might run it: http://www.newegg.com/Product/Product.aspx?Item=N82E168... But I would definitely go for the 600W Corsair. The thing is that is the bang for the puck power supply. m 0 l serginho August 28, 2012 10:56:03 PM GreenDutchAlien said:Yes, but it's a REAL 600W.

I have the CX600 do you think I can use 2 x GTX 560 in SLi ??? m 0 l Smeg45 August 28, 2012 10:56:19 PM Corsair TX 650 v2. Simple. As an all rounder the TX series can't be beat overall. m 0 l Smeg45 August 28, 2012 11:01:22 PM serginho said:I have the CX600 do you think I can use 2 x GTX 560 in SLi ??? You should start your own thread but I wouldn't. You are pushing it and the CX is a budget series. It SHOULD work, but I'd like a little more breathing room. m 0 l GreenDutchAlien August 28, 2012 11:04:58 PM Not advisable. 700W is advised, though it might run on it. System in IDLE = 201W System Wattage with GPU in FULL Stress = 449W Difference (GPU load) = 248W Add average IDLE wattage ~ 50W Subjective obtained GPU power consumption = ~ 298 Watts http://www.guru3d.com/article/geforce-gtx-560-sli-revie... m 0 l Deemo13 August 28, 2012 11:05:54 PM I wouldn't push it that close with the CX600. m 0 l Sunius August 28, 2012 11:06:20 PM Is there any reason why you're going with two HD 6850s in a new build? That's waste of money... m 0 l Sakkura August 28, 2012 11:07:04 PM This PSU is better than the CX600 and currently cheaper at Newegg: OCZ ModXStream Pro 600W http://www.newegg.com/Product/Product.aspx?Item=N82E168... m 0 l GreenDutchAlien August 28, 2012 11:07:34 PM Yeah, forgot about that, was wondering to. m 0 l darkenergy95 August 28, 2012 11:49:57 PM Sunius said:Is there any reason why you're going with two HD 6850s in a new build? That's waste of money... Got them cheap from a friend. m 0 l Deemo13 August 29, 2012 12:06:00 AM Well if you have them already, then you may as well use them. If you want to get the power to run the cards, I would look no less than the CX600 I listed. Any cheaper and quality is going to seriously decline. m 0 l darkenergy95 August 29, 2012 2:58:54 AM I can't seem to find that power supply in any New Zealand online shops (I'm from New Zealand). But I did find this which I'm considering...http://www.aywun.com/ProductDetails.asp?ID=141 m 0 l Smeg45 August 29, 2012 6:09:13 AM Not Aywun, you want quality, not throwaway junk. m 0 l darkenergy95 August 29, 2012 6:54:42 AM I quite like Aywun. Has anybody had any problems with them? m 0 l GreenDutchAlien August 29, 2012 9:58:00 AM Well reviews and comments ( for so far there are any ) aren't that great. http://www.priceme.co.nz/Corsair-GS600-v2-GS-Series-600... http://www.priceme.co.nz/Antec-Neo-Eco-620C-620W/p-8840... http://www.priceme.co.nz/Corsair-TX-650-650W-Fan-12cm-P... http://www.priceme.co.nz/Antec-650W-TruePower-ATX-Power... http://www.priceme.co.nz/Antec-620W-High-Current-Gamer-... http://www.priceme.co.nz/Seasonic-Seasonic-S12II-620-Br... http://www.priceme.co.nz/Corsair-600W-GS600-ATX-Power-S...

Even though its not 650w m 0 l Sunius August 29, 2012 9:54:47 PM Yes, it should work easily. m 0 l GreenDutchAlien August 29, 2012 10:55:08 PM Nice price to, good find.
