Help with choosing PSU Tags: Power Supplies Components Product Last response: November 27, 2012 4:41 PM in Components Share xXNeonBlurXx November 26, 2012 6:22:07 PM Hi all, I'm building a gaming rig in a few weeks, And I need to know what PSU to buy, as I am poorly educated on them. Here is my build: CPU: Intel Core i5-3570K 3.4GHz Quad-Core Processor ($229.00 @ PCCaseGear) Motherboard: ASRock Z77 Extreme4 ATX LGA1155 Motherboard ($139.00 @ PCCaseGear) Memory: Corsair Vengeance 8GB (2 x 4GB) DDR3-1600 Memory ($46.00 @ PCCaseGear) Storage: Western Digital Caviar Black 1TB 3.5" 7200RPM Internal Hard Drive ($99.00 @ PCCaseGear) Video Card: Gigabyte Radeon HD 7950 3GB Video Card ($325.00 @ PCCaseGear) Case: BitFenix RAIDER Mid-Tower Case ($94.99 @ Mwave Australia) I will not be using Crossfire, but I may do some minor overclocking in future if the need arises. My budget for the PSU is $120. Also, let me know what you think of the build itself, thanks! P.S. Sorry for no links, I'm sick at the moment and I can barely move, aha. More about : choosing psu richi3d10 November 26, 2012 6:27:32 PM I would recommend a corsair TX 550, I doubt you will need more than that if your not going to crossfire. Build looks good, it might be good to get 1 x 8gb ram, it gives you more room to upgrade in the future. I would also invest in a 128gb SSD if I were you, it greatly increases to speed of boot and game loading. That case is cool, another good choice could be the CM haf 922 (but this comes down to personal preference). m 0 l prototype18 a b ) Power supply November 26, 2012 6:50:20 PM Well 7950 CF (im includin CF option down the road) need 360 W So add 77WCpu and 15W hdd 25W Dvd 16W Ram =520 W including some OC. So a 650 W will be great. Right now you can get this http://www.newegg.com/Product/Product.aspx?Item=N82E168... Or this http://us.ncix.com/products/?sku=59616&vpn=P1650SNLB9&m... Personally i would get the Xfx 650W. Its a great PSU and will do the job. http://www.jonnyguru.com/modules.php?name=NDReviews&op=... m 0 l Related resources Need help on choosing a new PSU - Forum Need help choosing PSU - Forum Help choosing PSU for GPU - Forum Help Choosing Motherboard,CPU, PSU and Hard drive - Forum Help choosing the right PSU - Forum Can't find your answer ?

I have Tx 750 and have tooooons of cables. And its easy to manage them m 0 l xXNeonBlurXx November 26, 2012 9:47:43 PM Okay, thanks. The Corsair TX 550M is modular, and there is no 550w corsair psu that is not modular, that's the only model. Should I get that? m 0 l prototype18 a b ) Power supply November 26, 2012 10:14:38 PM Well u better of getting Seasonic M12II 620W or Corsair Hx650W http://www.superbiiz.com/detail.php?name=PSM12II620&c=C... http://www.newegg.com/Product/Product.aspx?Item=N82E168...
