I've not really found a reason to switch to SSD when a modern SATA disk will vastly outperform period hardware and push the limits of a UDMA100 port. Not counting speed, silent operation is another big advantage that SSDs have. Even modern SATA HDDs can get pretty loud. And I don't mean while …

One great thing about FSP and Delta Electronics PSUs is that most of these OEM models have rather strong 5v rails making them useful for socket A rigs, and others (older 200-250w models) even provide -12 and -5v, great for older builds with ISA slots running an ISA sound card (some sound cards …

My personal experience with the cheap China adapters is that they work fine* for hard drives, but an SSD will be unbearably slow within a few days of usage. Perhaps mine is a dud, but honestly at this point in my life I'd rather just spend the $20 to have a known good controller with the Startech …

I generally use FSP PSUs whenever I can. They are cheap and reliable used by many reputable OEM companies for their work stations. For your PC I'd go for something around 300W. Even that has twice the output you would need. For used PSUs I lean towards Seasonic, FSP and Delta Electronics. Zippy/ …

I think I will return the PSU, I noticed that when I connect the PSU to the power and press the power switch, the fan doesn't spin... And if my memory doesn't fail (it has been ages since I had to deal with old hardware) that is not a good sign :( I share a picture of the inner of the PSU just in …

Any old hardware is a potential bomb. It's part of the risk of having and using old hardware. You can also lift the skirt of your PSU and share some pictures. The general construction of the supply will give some indication if it includes over voltage and over current protection. With detailed …

I'm not aware of soft synths which do XG aside from S-YXG50 from Yamaha. That might be viable using an x86 Chroot and Wine depending on the emulation overhead required, but it does involve jumping through some hoops.

It looks to be fairly complete, although it's hard to be more specific without checking semiconductor ratings and capacitor selection (edit: Teapo is mid tier but can last in PSU applications given decent cooling). I'm also terrible at spotting two transistor regulator circuits and always have to …

Properly testing a PSU, whether it be AT or ATX, is moderately involved and preferably involves some sort of load cell (for all supply voltages), a decently accurate multimeter for measuring steady state voltage and/or current, and an oscilloscope for measuring voltage stability, transient response, …

One big change between the SC-55 and SC-55mk2 was in the implementation of capital tone fallback. Search around in the forums and you'll learn more than you ever wanted to about CTF. It's one of those topics which provoke lots of complicated discussion, like people asking about the best sound card. …

I am working on replacing some capacitors on a few video cards... If the capacitor on the card was 1000uF 125 Degrees C, 6.3V, putting a 1000uF 105 Degrees C, 6.3V in its place would not be a good idea? Just curious as I have 105 Degree capacitors.......not 125. It really depends how cool the air …

Qjackctl or any of the visual patch bay utilities (patchage, for instance) should do the trick. IIRC there was some difference in terms of which API layers have been activated by Munt. Testing required! I usually use the 'Midi Through' devices to make the virtual connections a little more flexible. …

On the bright side, the ALS100 is SB Pro compatible and does support the SB16 instead, which almost has the same capabilities as WSS (SB16: 16bit, stereo 44Khz).. 🙂 Almost, but not quite: WSS specifies 48kHz. 44 vs 48kHz is the whole sampling rate problem. Whether this is at all relevant here is a …
