Question; even if I open up both the 8500 and 780 computers to get the PSU measurements,I don't see any online measurements for the PSU? So how do I know if they'll fit? Also how do I verify cable length online other than comments? Robert I've been trying to place the "standard dimensions", where the faceplace of the supply fits your PC, into the first two dimensions. The third dimension is the length. Modular supplied, where the cables unplug, add a slight bit of length to the supply. 6.3" is 160mm. You can check your PC for the length of the current supply and compare. SeaSonic SS-650KM ATX12V 80PLUS GOLD $91 (+3.3V@25A, +5V@25A, 125W) +12V@54A, , ??? Modular, no pictures 3.40" x 5.90" x 6.30" https://www.newegg.com/Product/Produ...82E16817151088 To see the cables, I find a review. http://www.jonnyguru.com/modules.php...Story&reid=169 Modular, Fully sleeved, colored wires (can't see if coloring is correct) Modular Cables (each "length" is position of connector, the long portion being the part next to the power supply. Three measured numbers represents three connector details. The floppy power is an "extender" you plug into another cable.) ATX connector (560mm) 20+4 pin 4 pin ATX12V connector (570mm) 1 8 pin EPS12V connector (570mm) 2 SATA (350mm+150mm) 2 SATA (440mm+150mm+150mm) 3 SATA (540mm+150mm+150mm) 3 5.25" Drive (350mm+150mm) 2 5.25" Drive (440mm+150mm+150mm) 3 5.25" Drive (540mm+150mm+150mm) 3 3.5" Drive (150mm 5.25-3.5" adaptor) 2 6+2 PCIe (580mm) 4 You'll never feel any heat come out of that. 90% efficient.

It does have good reviews.
I'll take the measurements of the 8500 and 780 PSU,'s tomorrow with screenshots. Robert |

Robert There was one "bottom dweller" I trusted, because I bought one :-) The inrush was a little high (makes the lights dim for a fraction of a second), but the customer reviews had hardly any failures listed. And at one time, I would buy HEC supplies (Heroichi???). Which were old-fashioned or traditional designs, and I never had one of those blow up. But if you read the Newegg customer comments for some of them, you begin to wonder if they're a good deal. Even if only 3% of people write in and give their "bad" story, maybe that's too much. I was surprised on one of the questionable brands I was looking at yesterday, to see a report of "flame" from the thing. It's been a long time since someone reported something like that. I've had one smoke (an Antec CMT one), but that's about as exciting as it gets here. The smoke would come from dried-out +5V electrolytics on the output side. just as the power came on. After they "warmed up" a bit, the smoke would stop. Eventually, the PC crashed. And one other thing you look for, is PSUs that damage other computer components when they fail. One famous Bestec model, used to put something like +9V on the +5V rail, and the only thing you got to keep after that happened, was the RAM DIMMs and the CPU itself. Everything else was ruined. Many modern ATX supplies have protections that result in fewer ruined components. That's why your $90 supply has a list of those: Protection: OPP, Output Power Protection (thermistor based???) OVP, Over voltage protection (prevent +9V on +5V rail) UVP, Under voltage protection OCP, Over current protection (maybe 25A per loom) OTP, Over Temperature SCP Short Circuit Protection (maybe 54A total measured inside) Some of those overlap a bit. The OVP is pretty important, The UVP not so much (except in cases where voltage sequencing is assumed). That's why UVP is not specified in the spec. A google shows you can learn more here.

I did see some of the bad reviews and had
the same thought but I put that against the entire reviews and it didn't seem so bad but taken your comments into account maybe there is something to it? It does seem to be a good one though. Robert |

It does seem to be a good one though. Robert I've bought some of my supplies during clearance sales. One brand no longer wanted to do warranty repairs here, and decided to get out of our market entirely. And I got a couple supplies while those were being cleared out. They were a good brand, so I wasn't particular worried. Those are the supplies that run my main machines today. I don't know what the tariffs in 2019 will do to the price of these things. As otherwise, there should only be the normal seasonal variation in price. Paul |

I have a Dell XPS 8500, with Windows 7 Professional, SP1, with Spywareblaster, Malwarebytes, Avast , Windows Defender and Windows firewall. Hmmm I thought I had Windows Denfender but it's not listed in Programs and Features. and come it think of it , it hasn't come on for a scan in a long time now? I can't remember if this was manual or not? I do all the other scans and updates.

Well that's weird how it grayed my message
like that? I had it all black,.. I also wanted to ask you while I was updating Spywareblaster it has an option similar to making a restore point. Should I go ahead and do that as another precaution? Thanks, Robert |

Robert 5 3/8 and 5 1/2 might be similar to the products which are 140mm long (5.51"). 3.39" x 5.91" x 5.51" \___________/ | Length Faceplate +-------------------------------+ Front | PSU | | DVD drive | of PC | +--+ +-------------+ | \ +----------+ | === cable loom drapes down, |- LEN --| and you want sufficient | room so the lump of cables on the left, clear the back of the DVD drive on the right Your existing PSU could be a 140mm one. The one you've selected: https://www.newegg.com/Product/Produ...82E16817151088 is 6.3" long or 160mm. That's 20mm or 0.8" longer than before. The modular cables, the connector body where it meets the ATX PSU casing, that part doesn't bend, so the loom sticks back a bit further than a PSU with a captive cable and a grommet where the cable bundle leaves the ATX. I don't think it makes any difference, unless you can see already it's quite tight with no maneuvering room at all. It could be 1.25" closer to the DVD drive connectors than before. At a guess. If it's modular, you don't have to plug all the cables in. That's good. But the cables that do have to be plugged in, they need to be "folded up" a bit, to take up the slack. In my current system, this folding deal is quite a nuisance. The last work I did in the PC, I had to rearrange that rats nest again, use some cable ties and so on, to get some finger room to do stuff there. Even with modular, it doesn't solve all problems. Some people have custom modular cables made up, or they get a crimping tool and pins, and shorten the cables to give a custom fit. You can do that with the old Molex, but the SATA ones are not amenable to that sort of thing. (There might be a tool to install those, but the modern SATA fitting method and the power ribbon cables, I don't know if I'd want to try that myself. Don't want a smokefest if something shorts out.) My builds don't win beauty contests - I just make sure everything fits in the case, no fan blades got jammed, and I'm done. I don't "hide" the cables behind the motherboard tray or anything. I *never* buy cases with transparent side covers. Most of the space in my PCs is taken up by heatsinks. Paul |

Should I go ahead and do that as another precaution? Thanks, Robert The Spywareblaster could be making a real restore point (System Restore). This implies it is installing newer code for some reason. Restore points have a copy of the Registry, and they also capture the state before a program installation was done. In an emergency, you can enter Safe Mode and restore to the previous point in time using that Restore Point. Now, if this is a restore point internal to Spywareblaster, I wouldn't know a thing about that. I don't use that product. Paul |

These of course are backups PSU's so I'll just
check the contents of the packages to verify I have everything. So it'll fit although close, but as you say I'll just fold and zip tie the cables and keep it as clean as possible and away from the fans. Thanks, Robert |

I was thinking about the size of the $91 Seasonic X
,. so I looked further and found this. It says it's compact, 125 MM. https://www.newegg.com/Product/Produ...24&ignorebbr=1 What do you think? Robert |
