Building a new PC

Last response: in Systems
October 6, 2009 5:27:53 AM

BUDGET RANGE: $650-850 After Rebates

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Some engineering drafting programs for home use (ProE, AutoCAD), some gaming.

PARTS NOT REQUIRED: keyboard, mouse, monitor, speakers, tower (I do need a power supply)


PARTS PREFERENCES: I would like to use an Intel i5 or i7, or if too expensive a Core 2 Quad or equivalent AMD Chip
Windows Vista or 7
Blu-Ray Player, 1 GB Video Card Radeon or GeForce

OVERCLOCKING: Maybe SLI OR CROSSFIRE: Maybe, if this is better for the price than a 1 GB card.


ADDITIONAL COMMENTS: I am reusing a case dimensions 20.5"x17.5"x8" with two fans in front and four in the back, top, and side

I like this build, looks good. If someone couild give me an alternate for the video card that would drop me a little closer to the middle of my price range it would be good.

Also, how can I tell if the cooling will be sufficient?

Your monitor resolution is on the high end, so if you'll be using this build for gaming you'd want a decent graphics card. What games do you play?

You case has a lot of fans so I think the cooling will be fine.

My computer now has very poor graphics, but when I upgrade I plan to play games which would normally be played on an Xbox or ps3 like L4D, Call of Duty, fallout 3. I am not much of a PC gamer, but I am hoping to avoid buying a console since I need a new pc anyway.

Thanks for the advice.

How do I know what wattage I need on my power supply? The original suggestion was for a 600W, what risk do I take by buying the 500W?
October 6, 2009 6:52:38 PM

The 500W PSU will power your system just fine.
October 6, 2009 7:34:37 PM

You linked to the same 500W OCZ PSU I linked above. Any PSU built around 2002 will not have enough power on the 12V rail to power a 4870 1GB. Re-using a 6-year-old PSU is just asking for trouble.

An ocz 500W should be fine

What make and wattage is it?

PSU efficiency decreases over time (it's called capacitor ageing), so it's most likely that PSU you have from 7 years ago won't output the same amount of power as it did back when it was still brand new. You'd be taking a risk if you were to re-use it, it could fail and damage some of the other hardware.

I certainly wouldn't risk it. That PSU doesn't have active PFC and only about 70% efficiency.

And no PCIE power cables either. Definitely junk it.

Just curious, does anyone want to spec out a similar AMD build?
