I'm trying to build a cheap, small, gaming pc. Here are my components.
SILVERSTONE Sugo Series SG05BB-450
ASUS P8H61-I (REV 3.0) LGA 1155 Intel H61 HDMI USB 3.0 Mini ITX Intel Motherboard
Intel Core i3-2120
EVGA SuperClocked 01G-P3-1567-KR GeForce GTX 560 Ti (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
Thermaltake Slim X3 CLP0534 80mm CPU Cooler
LITE-ON CD/DVD Burner(Slot-load) 8X DVD R 8X DVD RW 6X DVD R DL 8X DVD-R 6X DVD-RW 8X DVD-ROM 24X CD-R 24X CD-RW 24X CD-ROM SATA Model DC-8A2SH - OEM
Western Digital Caviar Green WD10EARS 1TB 5400 RPM 64MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive
G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL9D-8GBRL
StarTech SLSATAADAP Female Slimline SATA to SATA Adapter with Power
And a 120gb SSD i have from a previous build.
My questions are...
1) Is the 450 PSU enough for the 560?
2) Will the i3 be a bottleneck?
3) Is it possible to go cheaper? Right now i'm at about $822 from newegg (including year replacement policy)
This has to be a small system, because i'm going to take it with me to South Korea, where there isn't that much space. I decided against a laptop, because they cost more, and it seems every year or 2 you need a new one.
I think the 450 would be pushing it. You'd probably be able to get by, but it would certainly be inefficient (PSUs lose efficiency close to their load limits). I'd go with at least a 500, and a 550 or 600 wouldn't hurt.
I don't think the i3 will bottleneck, but I'm not sure.
Cheaper in what sense? Cheaper with exactly the same performance?
