What Power Supply do I need?

post #1 of 19
Thread Starter 
I'm having a difficult time determining which power supply to buy for my future build. I'm currently stumped on how much wattage is needed to keep the computer running great without generating a large amount of heat. Here's my components used for my build.


Mother Board: ASUS M5A97 LE R2.0 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard with UEFI BIOS

Processor: AMD Phenom II X4 965 Black Edition Deneb 3.4GHz Socket AM3 125W Quad-Core Processor

Graphics: EVGA 02G-P4-3651-KR GeForce GTX 650 Ti 2GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP Ready Video Card

Memory: Crucial Ballistix Sport 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) Desktop Memory

Hard Drive: Western Digital WD Blue WD10EZEX 1TB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare

CD/DVD: LITE-ON 24X DVD Writer Internal Model IHAS324

Also I will be adding 2 - 200mm red led and 2 140mm red led case fans for better cooling.

Out of all of this how much will the wattage total to and what power supply would you recommend.

I used a few power supply calculators and they seem to have different results. Any help would be appreciated. Thanks a lot.

a 350w PSU would run that system but since thats not practical a corsair CX430 for $45 would work perfectly.

A good quality 650W would do (gives you a LOT of wiggle room). Prime examples are the TX 650, NZXT Hale90 650, Lepa 650, pretty much any enermax 650. The High Current Gamer and High Current Pro 650W from antec are other good choices, Though I would grab a 750 or an 850W PSU so that you have room to grow in the future, Then again, I got away with a 650W for years lol.

Id say you are looking at most maybe 200 - 250 watts usage at full usage so any quality PSU will do fine. If you are looking to go a less expensive route and live in the US you might look at this one http://www.newegg.com/Product/Product.aspx?Item=N82E16817371031

Can get down to $30 with the MIR and is a solid PSU and will offer an upgrade path if you decide to get a higher end video card in there. thumb.gif

Welcome to OCN smile.gif

Your setup uses less than 300 watts total when both CPU & GPU are under 100% load at the same time (very rare).

If you live in the States, the Capstone 450M is one of the best valued high-end PSUs around.

If not, look at this Database which only contains quality PSUs and choose one that's on sale in your country.


Here's how to put your rig in your sig:

A decent 350-400 watt PSU would be way more than enough for this build, check out this sticky for options in that category. http://www.overclock.net/t/183810/faq-recommended-power-supplies

Do you plan to sli in the future? If so Id say a quality (silver, gold, platinum) 650w would do you. Otherwise Id look at the rosewill capstone 450m, or the seasonic equivalent. The neo eco line mentioned above is excellent and I have had zero problems with any of the builds I have used them on.

Thanks for the info. I was going to go with the corsair cx 430. But I was wanting to know that if I used a 650-700w power supply if it could mess anything up beings it having a lot of power that my system wouldn't use. The reason for this is I'm wanting to add more stuff later on but be able to run it with what I have currently until I get the money for the other parts to further upgrade it. I'm not wanting to buy one power supply that's not going to be enough for when I add more stuff to it later on. What would you recommend for this?
