Very few performance differences to be had with sound cards in a modern OS... I would give the Audigy or X-Fi zero performance benefits. Back in the day there were differences. Modern equipment isn't really made for MIDI so you also would not get any benefit from trying to use relatively modern …

It is a 430w PSU as it turns out, 20A on both the +3.3v and +5v and 110w combined What ratings do you think it will need to work? 110 watts for those rails is low especially when you're doing something like V2SLI. I'd say you should get something where that rating is more like 150 watts or higher. …

Trivial is in the eye of the beholder. For an EE or an electronics hobbyist, sure. But let's not assume everyone putting together a retro PC has the knowledge to source, correctly solder, and implement a voltage regulator as an addition to their retro PC. I dunno man. People into old electronics …

sidenote - I haven't downloaded that BIOS file but if it is .exe then make sure you extract it before you flash it (if you end up buying a flasher). Not sure if this was obvious to you or not, so I figured it might be best to make sure. Hopefully it's not the flash tool with the BIOS integrated, or …

Chip legs also get ruined if they are repeatedly removed and reinserted via wiggling them if you wiggle too much and bend the legs. That's probably what started this. You've gotta be fairly careful about pulling with even force if you're not using a chip removal tool. I don't think those numbers …

Well, i actually like to collect CPUs in general, but the majority of them are P4 as my signarure says, i know Netbrust has it's shorcommings and it wasn't the best compared to AMD K7 or K8, the main reason is the boards since i don't have really much spares for 865PE mobos, i only have a Gigabyte …

I dunno what it's worth to you. Maybe you could resell and make a little money, but not much. Also your signature here says you have quite a lot of Pentium 4s already. (I'm also personally biased against P4 as Netburst was a terrible architecture, but clearly you disagree in some way or you wouldn't …

It's trivial to add a -5V line to an ATX PSU. Just wire in a 7905, powered from the -12V rail. Can be done internal or external to the PSU. or a MAX739 or similar inverting DC-DC converter that can run off of the 5v rail or 12v rail and provide -5v output (hence the "inverting") Your idea is of …

Yes they are both DIN5 (5 pin DIN connector) and the MIDI cables are wired straight through, which is exactly what you want whenever you use any kind of extension cable. So yes, you can use a MIDI extension cable as an AT keyboard extension cable and vice-versa, and you can hack up cables for one to …

If you are in the US, Mouser and Digikey are good resources. Agreed overall but watch it with Digikey, $5 fee if your order is under their threshold of $25 or $20 (can't remember which). Not a good choice for just a few capacitors, but great otherwise. (This is of course something that would be …

Probably won't work. PSUs have a minimum load, especially on the 12v rail for newer ones. I have an AX760i in my main machine. Very nice PSUs made by Flextronics (the AX non-I series is made by Seasonic and the I series is made by Flextronics, both high quality). Or at least be prepared to load …

Either the silkscreen is backwards or the original caps were installed backwards. If it were me, I'd verify with a multimeter before calling it good. It certainly wouldn't be the first time for a manufacturer to install caps backwards... Go apply DC voltage to a backwards electrolytic cap ;) (not a …
