Is there a way to power an LED strip off a power bank? It'll be really useful for making adjustments inside my PC.

If that strip will accept 5v power then it should be as easy as splicing power to it.

Get a USB Led strip, if you plug it into the power bank it should work. The power bank doesn't know whats plugged into it so it just gives whatever the output is, power.
[QUOTE=Kiwi;52741776]So I did some rough calculations(can’t sleep) and the rgb strip 5 volts dc at 7.2 watts (as stated on the manufacturer at 1 metre and let’s assume this is maximum draw) it should be pulling around 1.4~ amps. Suffice to say I don’t think I’ll be running a second strip 1m strip without some serious power issues.
Guess I’ll be looking into a 5-12v transformer that can handle 3-5 amps(breathing room in case I get a third strip).[/QUOTE]
USB hub with multiple ports and a high rated external power supply? Or maybe one of those large multi-phone chargers with like 5 ports?
[QUOTE=Kiwi;52741930]High rated adapter. Preferably with a USB port for AU/NZ
American plugs exists but AU/NZ are super rare unless it’s Type C. I could adapt for it but I really don’t want more hassle.[/QUOTE]

Here, this seems to fit the bill perfect. 2.4 amps per port, and can take 240 volts input. Just get a plug adapter and it'll work easy peasy.
Do none of you guys have a clue what you are doing? A LED-strip needs a LED driver, either constant voltage or constant current.
That multiport device is not appropriate for outputting that much current to a single port, USB in general isn't really.
So my power supply started sounding like thunder and smoke started pouring out of it. Now the whole apartment smells like burnt electronics.
RIP Corsair AX850, 6 years of service. Hopefully warranty goes through :(

I thought this was a USB LED strip that's self contained, not just a USB cable spliced into the power wires for a strip.

6 years. That's a good amount of years! Thank god you didn't buy a cheap one, cause you've also got those people who go for the cheapest PSU they can get and don't care. I've always built PCs with good cases and PSUs.
-edit: spelling-

I guess it is indeed a good amount of years, doesn't change the fact it sucks it died :v: and yeah I wouldn't wanna cheap out on the part of my computer taking in 230 volts and risking everything.
Also put in a spare PSU and it doesn't have a 8-pin, only 4-pin for CPU which isn't enough to boot into Windows.. this is really gonna suck lol
At least in Sweden most of your retailers seem to have storefronts for quick buys

It's a generic LED strip where all LEDs are driven in parallel, and current limited with a resistor.
As long as there isn't too much voltage drop on the rail, it's fine.
Just power it with an external 5v power supply. Something like a cheap meanwell PSU will be perfect for what you need.
[URL="https://www.amazon.com/MEANWELL-Switching-Power-Supplies-LRS-75-5/dp/B018TDT20I"]Here's a good[/URL] one that will provide more current than you'd ever need. Plus it's got overcurrent protection built in.

My Enermax 82+ Plus Pro is coming up on 8-9 years of use. I'm the verge of grabbing a new PSU, but at the same time... I mean, shit works.

6-7 years is about as long as I'd keep a PSU on a higher powered system
how do you even use computer components for 7 years
i just sell my old shit

I'm sitting on an i5 2500 (non-K) and a 6950 and I don't really use my computer for very demanding tasks very often. Selling it probably wouldn't bring in that much, and honestly (in my case), why should I just to buy some hardware I won't utilize.

[QUOTE=Levelog;52742885]6-7 years is about as long as I'd keep a PSU on a higher powered system[/QUOTE]
Yeah, that's basically the only reason I'm even thinking of changing it. I wouldn't really call this higher-powered, though, it's like 300-350W under load, which doesn't occur very often.
Still, a PSU for a system you want to be running well is a good investment. A half decent unit replaced every 5 years is like 83 cents a month.

because it's nice.
that being said a 2500 is plenty, but all my motherboards of that era have dead and it's not worth buying new ones

I'll probably get a new one when I get some cash flow going in a month or two - I'm eyeing an RM650X (or well, that's what I settled on about a year ago, so I should probably update that), but it'd cost me about month's income, and I have books to buy (and other shit). It's coming up.
Still, I looked inside of it half a year ago and didn't see any bulging caps or the like, and I haven't had any stability issues. Wouldn't recommend this to other people (especially if their systems wasn't non-essential like mine), but I think it'll chug along until I can justify the upgrade.

Shit doing this math on more components I should start doing gaming PC's as a service.

The family desktop is like 8 years and the PSU died recently, so we got a new one. It still works fine for office work, videos and whatever else the family desktop is used for. It's using a 1st gen i5 too.

A striking amount of dead 1155 boards are fixed by replacing or reprogramming the bios chip. If you come across one, try reprogramming it.
If it's a gigabyte board you can even just replace the CMOS battery, around then they often acted like dead boards if the voltage on those dropped :v:

Can confirm. I fixed a few by replacing the socketed EEPROM's with new ones flashed with fresh BIOS.
Seems like they only last between 3 to 4 years.

I've had a couple people from my deployment approach me about helping them build new PCs. I've just taken the "give me a budget, I'll build it out online, then you buy the parts, ship them to my house, bring a 6-pack over and we'll build it together" approach, but mostly because these guys are friends.
After building my first desktop by myself, I'd probably die of blood loss if I went into the computer building business...
