BTW my relative owns a recording studio and his finest rig is a Nagra open reel digital recorder, amazing sonics. Flat to 10Hz.
I can't pin point the irritating buzz my psu made before it shut down. I reckoned it to be coil whine except my system shut down completely. Didn't stay running. More a sound of under voltage (brownout) frying. It's running right now and makes me feel tentative about gaming on it.
a while back, I bought a bogus Corsair RM750 (in 2013) from the advice of a friend and I regretted it. Fried up a gpu, cpu and motherboard. Auto temp fan setting were wrong. Got hot and had a hint of that strange electrical burn smell. It had serial numbers that had been recalled before I bought it. Didn't find out till I RMA'd it. I can't understand why Corsair didn't remove the bad ones from retail shelves. Rather than reinstalling it, I gave to a friend.
So I got this XFX XTR 750w made by Seasonic. It's been running 2 years till now. Acts too, like it's going south. So I asked diggiddi if my spare 550w had enough power to push a 390 till I RMA'd the 750w. 550w. Got a 650w at my disposal, too.
I know the 390 & 390x has about a 300w power @top draw but how much can that spike up to? I overclock like everyone else does so I figure the draw to excess. Doing Ultra fps gaming, with 64 nut cases in Battlefiel 4, I'm thinking there's a chance I somehow destroyed this 750 watter.
Yeah, I remember Nagra. They also made a great portable digital recorder that was the love of audiphile world.They gushed with prasie, lol.
What's the name of your relative's studio? Guys like sound men and gophers use to roam from studio to studio. I worked with some guy (can't remember his name anymore) did mix work on jazz guys John Klemmer, Lee Ritenour and Joe Sample. Sorta fun.
I used a huge, cast iron Ampex tub for broadcast editing. It was just big, 4 track R & R, had it's own stand. Studer Revox made a dandy R & R. I think Nakamichi's were king of the hill recorders. It's amazing how they would rise past 21,000 hz. You began hearing the breath of recording halls, night clubs, the slick surface of guitar strings and stand up bass instruments, footsteps prattle around the recording stage, someone whispering for Ned to move his head. It was amazing what a cassette will do. In a good setup it would shine.
