  1. The PSU is going to take hot air from the case and exhaust it out of the case. If your PSU is oriented with the fan up and is not hidden by one of those shelves/shouds many new cases have, then your PSU is going to be taking warm-to-hot air to cool itself--can that be sufficient for PSU cooling if the air inside is hot? If you have it with fan down, it's going to take room temperature air to cool itself only.
  2. As an owner of a FD Define 7 Compact, I’m curious about the Fractal Design B-20 GPU riser. My processor is an i9-10900KF, so PCIe 4 is not an issue either way. What confuses me is the cooling of the back of the card and the motherboard area covered by the card. If the design of the riser pushes the GPU away from the side panel, it means the GPU is closer to the motherboard. Would that mean inferior cooling to the back of the GPU and to anything on the motherboard behind the card, such as m.2 drives? Looks like there are maybe 2.5” of room between the back of the GPU and the moth
  3. If it’s your own home, I’d invest in an electrician to add a new 15-20A circuit breaker for the AC using the closest outlet to the window. Using extension cords with an AC is not recommended as a fire risk (if you must use one temporarily, at least get a high quality 10-12 AWG one). If you are renting, you could ask your landlord for the same. Or invest in a high quality UPS, but probably the always-on kind. Hopefully someone more knowledgeable can chime in about those.
  4. P.S.: I don't know enough about small AC compressor units' inrush current: your particular AC might be fairly efficient and only have 2-3 times its rated operating current as peak (inrush) current. Here's a general article about Inrush Current: https://en.wikipedia.org/wiki/Inrush_current If your AC unit is rated at 8.2 A: https://www.kenmore.com/products/kenmore-77086-8-000-btu-portable-air-conditioner/ , your AC could be very temporarily drawing 16.4 A or even higher, and then once the compressor motor shuts off, there's a corresponding voltage spike.
  5. The more powerful an AC unit, the more start-up current it will use every time the compressor starts to work to do the cooling. The temporary spike current can be somewhere like 2-6 times its normal rated amp rating, from what I've read. This temporary power usage spike will cause a brownout for other equipment on the same circuit, and it can last up to a few seconds. If you have lamps plugged into that circuit, you will see them briefly dimming. I just wouldn't plug in delicate electronics like your expensive computer into the same circuit.
  6. I would not do that--every time the AC condenser turns on, there's a large quick spike in power consumption. It will mean a mini brownout for other equipment on the same circuit. Your AC might also be a powerful one, you did not say what it is.
  7. Indeed, that's a beautiful card. I'm hoping I can get one of those (or a 3070 version) sometime next year to match the rest of my white-silver set-up. By the way, I've seen a reddit post saying that you can pry off the purple stripe on the edge with some heat, such as from a hair dryer. https://www.reddit.com/r/nvidia/comments/jfbwjj/accidentally_removed_the_purple_bar_on_top_of_the/
  8. See pinned message at the top: "For help choosing a power supply please Create a New Thread asking for assistance including your budget and system hardware to receive the best answers relevant to your specific needs."
  9. Depends on manufacturer's specifications for that particular model. Some PSUs are designed to have a semi-passive cooling mode, and some have fan that's always on with varying RPM. Personally I like the always-on fan design, with quiet fans and low RPM at low loads. This way all the parts inside a PSU are getting some cooling at all times. If you don't have good dust filters on your case, always-on fan will mean more dust in the PSU over time (of course it also means you should be diligent about cleaning the dust filters periodically too, not set-and-forget). Plus and minus for everything
  10. For reference, one can also get a perforated stand to lift a computer case off the floor, if there's carpeting. Something like these monitor stands: https://www.amazon.com/ATUMTEK-Ergonomic-Platform-Computer-Projector/dp/B08PP28R72 https://www.amazon.com/Monitor-Stand-Riser-Adjustable-Ergonomic/dp/B07H4DMLVH/ (Have to check dimensions, of course, and if it's a super heavy full tower need to find larger and sturdier shelves). I'm using one similar to those in a silver color for my Fractal Design Define 7 Compact to give my PSU cleaner air, although I don't h
  11. There are so many different boards though in the Z590 series. There are even separate SKUs with and without WiFi card included. https://www.anandtech.com/show/16347/the-intel-z590-overview ^ 50+ motherboards! I was pretty shocked when building a new system this year -- there did not used to be such redundant variety. (The curious thing to me is that they all have fairly few USB ports on the mid-low end. You really need to pay significantly more to get more USB ports--which would be a useful thing for a lot of users--as opposed to including more over-the
  12. Fair enough I thought (hoped) there really was some good technical reason for it. I guess it's there to confuse the buyers about their PSU cable compatibility
  13. Right, but as I mentioned, extreme overclockers are usually not going to be doing extreme overclocking on budget Z590 boards, are they? Usually each brand has one-two high end boards intended for extreme overclockers. Moreover boards like my ASRock Z590 Steel Legend actually have voltages set to intel's default spec, without any hidden "auto" boosts (part of the reason I liked it, along with features and price)... yet the board still has 2 8-pin EPS sockets.
  14. Could anyone knowledgeable about this topic in technical terms please provide an explanation. I've noticed that even the basic Z590 motherboards, such as the smaller mATX models, now come with at least an 8pin and a 4-pin EPS sockets, and many (like my ASRock Z590 Steel Legend) actually have 2 8pin EPS sockets. In theory, going up to the most power-hungry LGA 1200 processor being ~i9 10900K/F: what's the benefit of two whole 8-pin EPS sockets? Is it for the tiny handful of people who will be doing LN overclocking? I imagine that's a feature that would be included in
  15. ^ With the thicker gauge wires being better, in case you have a bag with old spare cables and some old compatible cables might be too thin. Of these two plugs shown on the photograph, just reuse the one that fits for your outlets.
