    No.. it's not that I can't hold onto a job. It's that I'm really that old.

    Love what I do, but jaded by the industry. When poked, I do bite.

  1. You really should work out your cable management. Get some zip ties or more velcro straps.
  2. This one says "850W" and the color is "Gold", but I would say "no".
  3. Like I said in my first post, depends on where the short is. If you just take a +12V wire and a ground and short them against each other, that's SCP tripping the PSU. If you damage a PCB and the short is there, and the PSU has OCP, then OCP would shut the PC off before too much power is delivered to the short. Here's a prime example of SCP not seeing the short, and the PSU not having OCP: Here's a simple project: https://circuitdigest.com/electronic-circuits/short-circuit-protection-circuit-diagram Keep in mind this is a SINGLE o
  4. It's not simple to explain. Especially with multiple outputs where +12V to +5VSB or -12V is also considered a "short". I'm not sure if/when Aris will put it into his PSU testing/reviewing, but he could tell you that MOST PSUs have SCP that doesn't function properly 100% of the time. Fortunately, most of the time the PSU just self destructs (no damage to PC components), though some damage is possible in some corner cases. Usually, yes. I don't understand why you mean by this. If SCP triggers, the PSU latches off and stays off until the short is remov
  5. When I was a kid, I used to go swimming at Celebrity Fun Center in Denver. I'd swim for 30 minutes, then I'd take a quarter and play some video games. Except they didn't have ANY of those games on grounded outlets. If I touched anything metal on any of those machines, like the coin slot, I got a shock so horrible I thought I would die. So yeah... it's your ground. If you DO find that your outlets are properly grounded, the problem could be a poor ground within the PSU. Your chassis is grounded by the PSU being screwed into it. Inside the PSU, there's a ground s
  6. You have to take into consideration the resistance, not just of the short itself, but what is added by the circuit itself. When I see SCP working is when there is a direct short between an output and ground. When I see SCP NOT work, but OCP work instead (if it's there), is when the short is on the far end of a connection, like on the PCB of a failed hard drive or a failed graphics card, etc. where the short is on the device itself. The device itself typically doesn't have SCP (it might on it's own D2D circuit, but what if the short is before that even?), so the PSU keeps feeding
  7. It's never made sense. In DC circuits, VA is W. But Intel has always used VA in the spec.
  8. Fake 80 PLUS certification never instills confidence.
  9. HX1000 review: https://www.tomshardware.com/reviews/corsair-hx1000-psu,5214.html RM1000x review: https://www.techpowerup.com/review/corsair-rm1000x/
  10. 1. A 650W wouldn't be fine with a 3080. The transient spikes are too much. Should use a 750W. But since the price between 750W and 850W is usually pretty small, why not the 850W? 2. Considering people tend to keep their PSU for 10 years even if they upgrade the rest of their PC every other year, there IS such a thing as future proofing. I don't see the connectors changing on PSUs any time in the next few years. ATX12VO seems like a good idea, but I don't think it's going to get much adoption.
  11. There is no "in general" for any "brand" when they make a full gamut of product from price leading garbage to decent.
  12. I hope you're not using that PSU for any high end components. Use a multimeter to make sure the correct voltages are delivered to the correct pins on the other end of the cable.
  13. Exact same problem as before? What was the "EVGA 600W 80 PLUS" PSU you bought? Are you *sure* it's not the motherboard?
