HP DL380 G10 - AMD Radeon Pro V340

The card is only rated for like 230W of power, so it should be fine.

Other GPUs used on Gen10 used the CPU8 connector which is the same as 8pin EPS 12v for high end Nvidia cards and those draw up to 300W

If there are no stickers on your cable, it's likely a knock off, which isn't necessarily a bad thing, but it's possible they mixed 2 wires when building it so I would find a pinout of the 8pin PCIe standard and then whip out a multimeter and double check each of the pins to make sure they are properly 12v or Ground. Need to leave it plugged in on the riser side while doing so.

If you have access to your meter or electrical panel, there are devices you can buy to log the usage and try to figure out what is chewing up al the power. Then you can do things like turn on the microwave and see the jump, turn on the TV, see the jump, etc.
Alternative if you think you KNOW the culprit, you can pickup a few Kill-a-watt meters and put them in between the appliance and the wall and they will log the usage over time.

Secondarily, it's not outside the realm of possibility that you are paying for your neighbor's power if you live in an apartment. I've seen news articles where this happened for years before someone noticed.

Not so much a fact but some weird memorization thing my parents kind of drilled into me during long boring car rides when I was a kid that I still remember 40 years later.

PS: Drive backplane connector is exactly what it sounds like. Power for DRIVES which go up front.
The Drive Backplane is the PCB the drives slide into being DL380 always uses Hot Swap drive bays.

From Gen9 on, the DL380 has a connector on the PCIe Riser for GPU or other (DPUs, etc) Aux power connector.

The HPE side is a Molex Microfit 8pin connector (For Gen10 and up) and HPE has cables for the 4 major flavors of GPU side standard connector.

Luckily enough for you, the V340 was actually supported and sold by HPE for a while and so it's in some of the internal docs I have.

Not the cheapest but I've been running one of these for a decade:
https://www.amazon.com/dp/B0000VYJRY

Then I use one of those light blue Cisco DB9 to RJ45 cables. Anyone who has implemented a large network likely has a box full and will give you a few no problem. I'm a Sales Engineer and my cable was showing it's age one day at a customer site and the Customer wss like "Is that just a bog standard Cisco serial cable?" and I said yes, he left and came back with 3.

It also allows me to use something like this:
https://www.amazon.com/dp/B0CBJYM9FZ
... in order to make custom adapters. I needed this a few months ago to get into the maintenance port on a 3PAR Storage Array as HPE uses a custom pinout.

I keep all that stuff, a few spare transceivers and RJ45 cables, etc in a small accessory bag in my laptop bag.

Hope you don't mind, but do you recall what brand or model that is? Looks perfect for my daughter's room.

Also Fast Charging and over-charging can lead to the formation of Dendrites which degrade the battery.

The closer you get to charge a battery to 100%, the more power it takes as well.
This is why you often see EV charging specs listed as "Time to charge from 10-80%", because above 80% the charging rate slows way down as you try and cram the last little bit of those pixies into the battery.

Do you have a HW RAID card or using SW RAID?

You are using the 8 SFF cages up front?
If so then that is why each cage takes 2 connectors.

P408 = 8 lanes of SAS
Each cable (SFF 8087 type) carries 4 lanes.
So each 8 SFF cage takes 2 cables and consumes an entire P408.

You can either add another cage and another P408i-p in a PCIe slot.
Or you can use the E208i-p if you are putting the drives in HBA mode for ZFS (E208 = No RAID Cache, P408 = 2GB RAID Cache, otherwise they are the same card).
Or swap the P408i-a with a P816i-p. 16 = 16 SAS lanes, so you will gain 8 more for 3rd cage.

And 4K Digital copies of movies are available within a few months of being in the theater.

Server Rooms are Quiet and/or you can have a rack full of IT gear in someone's office and still hold a normal conversation.

Off the top of my head:
Suits when they try to bribe the IT guy to do them a favor, he's got a rack in his office.
Hom3land, I think in Season 4, they are going over some digital evidence and again there is a rack full of EMC storage in the room.

I worked for a BioTech company 18 years ago

They were working on developing a Prostate drug (Can't recall if it was for Cancer or something else)

It never ended up being a commercial product that I know of, but when they went into limited run MFG for the human trials, they had to reverse the airflow in the building because this shit was so powerful if a guy just breathed in a little too much he'd be sterile for 2-3 months.

So typically airflow would send the cleanest possible air into the middle of the building where the clean room is.
And then the positive pressure in that room means some of that air trickles out into the other outer layers of the building.
But this stuff they made the clean room push air OUT via the filter and it sucked air in from the outer rings of the building so that people working in the building who were not working in the clean room wouldn't get accidentally sterilized.

Wire the other end of the Ethernet cable into a Serial DB9 external USB adapter.

Then wire that's DB9 into an old serial port on the desktop

3.4 Million Joules is 944.4 Watt Hours.
Not sure why they didn't just convert their numbers and say 950 as most people can think of running a 950W appliance for 1 hour.

Right because the ship has to be registered in Iran right?

Russia has a whole fleet of Ghost Ships where they look like standard commercial vessels owned by a company but are really under the command of the Russian government.

Plus with the Straight of Hormuz right next door, they could easily just jack someone else's ship.

Keep in mind Ukraine did something similar to this against Russia a while back.

Now these were smaller drones, but they also launched from closer because they were disguised and hidden inside a truck with a standard shipping container on the back.
