Tags: Prebuilt Computer Systems Product Last response: May 4, 2011 1:25 AM in Systems Share kHRYZTAHL May 2, 2011 6:52:15 PM Hello, i have an old computer that i built back in 2008, and im going to use my old chieftec dragon case. And was wondering if i could use my old powersupply It's an OCZ Modstream 520W (620W PEAK 60sec) http://www.ocztechnology.com/ocz-modstream-power-supply-eol.html I've been checking out these online calculators and their all different and tell me from 480W and up to 560W. So i wanted to get an human prospective on all this. Anywho.. my new build would be: Motherboard: ASRock 880 Pro3 ATX AMD AM3+ Processor: AMD Phenom II X6 Six-Core Processor 1090T (3.2GHz) AM3 Cooling: CoolerMaster V8 Graphics card: nVidia GeForce GTX560 Ti Twin Frozr II OC 1GB DDR5 RAM: G.Skill 8GB Ripjaws PC3-10666 (2x4GB) 1x DVD Writer 6x 80mm Case fans (+2 maybe) Thanks in advance More about : computer run 520w psu rolli59 May 2, 2011 6:58:26 PM It will probably run but your PSU is a little low on the +12volts with 28amps when the card recommendation is 500watt with 30 amps on +12 volts. I would suggest upgrading the PSU for a more modern and efficient unit. http://www.newegg.com/Product/Product.aspx?Item=N82E168... bdbeall May 4, 2011 1:25:18 AM Hate to be a downer, but you need at least a 600W PSU for this rig. if you go a full load on proc and video card, you will not get it fro a 530W supply.
