Custom-Built Computer Parts

by Selwyn / October 6, 2004 5:40 PM PDT

Hi. I'm going to be building a custom computer in a few months, built for gaming (mainly RPGs and RTS's, so I don't need anything too fancy), and all the other normal computer tasks. I was thinking about getting these parts, and I was wondering what people think about them, or anything I should change. This is my first time building a computer, so help would be appreciated. Here's what I'm thinking:

Case: DYNAPOWER ATX Black Mid-Tower Case with 430W Power Supply, Model D58-BK

Motherboard: Intel D865PERL i865PE Chipset

Processor: Intel Pentium 4/ 2.26 GHz 533MHz FSB, 512K Cache - Retail

Memory: Crucial 184 Pin 512MB DDR PC-3200 8T - OEM

Video Card: NVIDIA FX 5500 256MB AGP

Floppy Drive: NEC 1.44MB Black Internal Floppy Drive, OEM

CD-ROM Drive: Samsung Black 52X CD-ROM, Model SH-152AEBUB, OEM

Hard Drive: SAMSUNG 80GB 7200RPM IDE Hard Drive, Model SP0802N, OEM Drive

Wireless Adaptor: NETGEAR MA111

The Nvidia Geforce FX 5500 requires 250W minimum power supply. In total, I tallied it up, and the whole computer requires 335W supply. My uncle (who's very good with computers, and has built many many ones) said that I should have 50% more power supply than I need, just in case, which would mean I need to take out the 430W supply and put in a 500W or 550W. Is this necessary?

In reply to: I add 100 Watts.

Well, I tried an online calculator, and it said the computer would need 235 watts. It seems like the built-in 430 watts in the case should be enough, right?

Btw, the link to the calculator is here:

I'll write that it's rarely that simple as Tom detailed so well in the articles. We have this problem with the vendors slapping optimistic values on the power supplies plus not revealing what power can be expected from a PSU after it's been in service for one year.

If indeed you were to draw 235 Watts, the a true 430 Watt PSU will be dandy even in a year or two.

Ok. Well, I'll try it. Thanks.

One question though: does the monitor add to the wattage you need? I have a monitor that takes up 90W and I was wondering whether I should add that in to the equation.

Oh, ok lol. I figured something like that since the online calculator didn't figure the monitor in.

The reason not to get an Athlon 64 is that I'm building this whole computer on a $400-$450 budget, and an Athlon 64 is just too expensive.

Why such a tight budget? If you increase your budget a bit, you can get so much better performance. Another option instead of an Athlon 64 is a Sempron 3100+. The Sempron 3100+ is basically an Athlon 64 2800+ but with half the cache, and the 64 bit features disabled. A Sempron 3100+ is only around $100. Imo spending around $150 on an Athlon 64 3000+ would be a much better choice than a Pentium 4 or a Sempron 3100+.

Re: DDR400 vs. DDR333 RAM
by Selwyn / October 18, 2004 1:10 AM PDT

One more question, for anyone willing to answer:

When I looked up the D865PERL motherboard (the one I will be using) on, I found the Tested Memory page, which can be found here:
Anyway, I noticed it seemed to say with a 533 MHz processor, I need DDR333 RAM, rather than DDR400. Is this correct? Just making sure.

Btw, it's a tight budget because I'm buying the computer with Chrismas and birthday money mainly ;).

Your motherboard can support both. it's jut that the recommended minmum spec ram is ddr333.

In looking at what you currently have and seeing that you may decide to upgrade some or all of your system, I would reccommend you replacing your current power supply with one of a larger capacity. You may wish to replace a floppy drive with a superdisk which would give you much more storage and is still backwards compatabile. Also if want to go with a combo drive, the prices are usually very competitive and you get both a DVD and CDROM drive in one (16x DVD/ 52x32x52 CDRW). Whether you decide to upgrade later, or just keep your system as is, your system will require a sufficient amount of power. So unless you want to replace your supply later, get one of a sufficient wattage just in case you do decide to upgrade later.

Also, make sure you have plenty of cooling and ventilation to keep that gaming system working fine.

totally agree on the cooling. and pretty much everything else you've said.

I found that connector you were looking for
by wangjiahua / October 6, 2008 2:51 PM PDT

Cindy, is this the thing you were looking for?
It's on the list of computer accessories and parts. They have the DVI video thing to convert that *** monitor to work with your other computer. Just about any other kind of wire adaptor, usb connectors, monitor extension wires, ps2 extention wires, and all kinds of female and male swap connectors and things that I think would help your shop. If that above link don't work then goto and click on computer accessories. Let me know if that is what you need and give me your email address again.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
