Solved How much Power do I need? Tags: Power Supplies Power Components Last response: February 11, 2010 2:01 PM in Components Share adamlevy February 11, 2010 3:28:48 AM How much power do I need from a PSU for the following setup? CPU: AMD Phenom II X4 965 (125W) MOBO: 790GX Motherboard with Sideport RAM (haven't decided which one) RAM: 4GB RAM VIDEO: (integrated 790gx) HDD: 2 WD Caviar Black 750GB HDDs I'd like enough headroom to drop in a decent discrete graphics card down the road if the IGP is insufficient for my (non-gaming) needs. Thanks! More about : power enzo matrix a b ) Power supply February 11, 2010 3:58:31 AM The CPU and graphics card on the pci-e bus draw the most power. For your current setup I doubt you'll need more than a good quality 400W like the OCZ series or the antec earthwatts or a corsair. Personally I would put in a 600W to give me decent headroom. However, everyone's opinion of "decent" is different. m 0 l adamlevy February 11, 2010 4:13:58 AM Quote:everyone's opinion of "decent" is different ^ Too true... For grins, let's say I threw in a single Radeon HD 5850. Would your 600W recommendation cover that as well? m 0 l Related resources How Much Room do I need??
