Re: Putting together a quieter computer

I don't think you'll hear any Seasonic running. I can't recall them ever making a noisy PSU.

Re: Something's different...

Come on, guys. How about an estimate of TR's current value? $100k? $250k? I doubt it's anywhere near that much. The community has mostly moved on, there's no content, and rankings are falling every day. https://www.worthofweb.com/website-value/techreport.com/ $45k isn't bad. I suppose the current o...

Re: Putting together a quieter computer

Seasonic makes consistently excellent power supplies. EVGA doesn't build any in house - some are excellent and some are garbage depending on the model/year.

Re: Putting together a quieter computer

Most power supplies highest efficiency occurs at ~40-50% of load, This used to be the conventional wisdom a decade or so ago, but newer PSU designs purportedly have a much flatter efficiency curve. It's still a good idea to not run a PSU right at its limit, but the "aim for double the wattage ...

Re: I need a Windows 10 x64 Sound Card

I'd be surprised if that chipset is unsupported in Win10; either the device is dead on the board or it was accidentally disable in the BIOS somehow. If it's not the latter, I second the USB suggestion. It's my go-to solution for anyone having trouble with sound cards.

Re: Amazon's new Contact Us is a fail

I haven't seen that yet. I prefer the chat system, but I can see why some may not. I just make sure I have 20 minutes or so to talk with them and it's done in one shot. I strongly dislike the back and forth over days via email.

Re: Amazon's new Contact Us is a fail

I'm including lots of very weird issues. Longtime Amazon customer with easily thousands of orders. It's actually why I prefer their chat system - when they misunderstand something you wrote (which happens a lot) it's a 5 minute conversation instead of back and forth via email over many days.

Re: Starfalcon has built a new computer....not a joke

It is closer to a 10-25% at best for overwhelming majority of mainstream stuff and games out there. There's a reason users held onto their Sandy Bridge/Ivy Bridge systems for so dang long. They are only biting upgrade bullet mostly to get newer standards and interfaces. Getting extra cores just swe...

Re: A surprising variety of SSD speeds

It's not just about speed but also data survivability in cases of imminent failure. Tape might be slow but is unlikely to vaporize all data in one fell swoop. RAID is not always an option. I hope future HDDs, or an entirely new medium, could achieve reasonable speed/capacity ratios, or improved rel...

Re: Block wear leveling count S.M.A.R.T. value

If you're talking about the raw value, it's a cycle count. If you're talking about the current/worst value, it's a figure that starts at 100 and drops to 0 over the life of the drive.

For mainstream stuff, not really that by much. 3900X will only show its muscles if you throw VMs, numbering-crunching and content creation stuff at it. I think you severely underestimate the difference between a 3770k core and a 3900x... Nope, it is pretty close under mainstream stuff. Zen2 isn't t...

Re: LED Light for Snowblower

Since it is a full-wave rectifier the flicker will actually be at 2x the AC frequency, which helps. Good point. It sounds like a typical running RPM for most snowblowers is 3500-4500 RPM, so it'd be somewhere north of 100 Hz, and that's likely not enough to bother anyone. http://www.bio-licht.org/0...

Durf. Thanks. I knew I was missing something; I should drink more coffee before posting. Two lights in series would mitigate any voltage-related concerns. I'd worry that nearly 26 volts peak would damage the LEDs. I'd guess it probably runs in the upper 6k RPM range if it's a small two stroke, but a...

Re: LED Light for Snowblower

VAC_RMS = V(peak)/sqrt(2). A bridge rectifier is going to give an output based on the peak voltage, so JBI is correct that 18VAC (RMS) ~= 25VDC (before conditioning and ignoring diode forward voltages). That 90% figure sounds more like the efficiency AC to DC power supply. /opinion It's been a whil...

Re: LED Light for Snowblower

Something else you may need to consider - if you do get 18VAC out of the generator, once rectified and filtered that's going to be around 25VDC. For a full-wave rectifier wouldn't the DC output voltage be a little less than the 18 VRMS input? I don't recall the exact math off the top of my head, bu...

I honestly see zero problems with what you just posted. It's clear, it conveys context, and it's easy to read. It immediately shows you what can/can't be selected at a glance.

Perhaps it's nothing to do with stubbornness on anyone's part but your own.
