Hey guys,

I am currently finishing up a computer build as follows:

AMD Phenom II X4 955 Deneb 3.2Ghz (http://www.newegg.com/Product/Product.aspx?Item=N82E16819103808&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_-)
8GB (2x4GB) Kingston Hyper X DDR3 1600 (http://www.newegg.com/Product/Product.aspx?Item=N82E16820104173&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_-)
ASUS M4A87TD/USB3 w/ 870NB/850SB chipset (http://www.newegg.com/Product/Product.aspx?Item=N82E16813131651&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_-)
EVGA GeForce GTX 470 1.2GB GDDR5 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814130616&Tpk=evga gtx 470)
80GB WD IDE HDD
200GB WD SATA 3.0 HDD
Sony CD/DVD R-RW
NZXT M59 Black (http://www.newegg.com/Product/Product.aspx?Item=N82E16811146058&Tpk=nzxt m59)
1 - 140mm case fan
3 - 120mm case fan
Xigmatek HDT-S1283 HS/Fan (http://www.newegg.com/Product/Product.aspx?Item=N82E16835233003)

My plans for this system include overclocking the CPU to 3.5-3.6ghz and overclocking the GPU to 10-15% (depending on whats stable and not too hot)


My question is:

Will the Antec BP550 550W (http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_-) be enough to run that system at stock? What about overclocking to my desired settings?

Your build looks fine and yes that PSU will work. I'll recommend a couple of changes though. First, get rid of that IDE drive. And second, change the video card to a GTX 560 Ti. It gives similar performance all the while being less noisy, more cooler and has a lower power draw.

'Yes' to both, but you will not have much headroom for future upgrades and PSU deterioration (aging of caps) over time. Consider 650 Watts or above.

The GPU was actually a gift, typically I would buy Radeon's for myself but Im not gonna turn down a free GTX470 ^^

Thanks for the responses guys, much appreciated.


Side note - This PSU, despite being only a 550W rated has a 12V rail total of 69A. Seems kind of insane the difference between the two..
