At the moment I'm using 8 Sony / Murata US18650 VTC6 3000mAh - 30A.
No need to wrap yet, I do have extra sleeves though when needed.

well my Athena mech squonker had a tendency to scratch the negative pole wrap, not major but the SQ+ wraps do not even get a dent in them and they look freaking better in black than green (yeah i am petty ... )

Well its there for when you want to come visit..

Mod's aren't all super human you know, late night post and being half asleep... Just for you, I'll remove them, but if you turn up I expect some flowers......

Hey i'd visit you if the pandemic wasn't on

55 minutes plus a bouquet sure beats 3 hours to Victoria station

My first SSD in PC, it was time to retire my fleet of hot and noisy 15k drives (I like the sound of the drives, but did not like the sound of fans to keep them cool).

Tomgang · Nov 20, 2020

Last week i got this home for my new PC: https://www.techpowerup.com/forums/...h-related-purchase-thread.225885/post-4392655

Now life support to my system is here to.

I was considering going for one of those but couldn't find it that cheap so got a Sandisk extreme pro 1TB for £100, it's pretty much the same as the WD Black sn750.

Bargain price!!

I think I paid £74 for my 500GB model a few weeks ago... It's about £70 now ...

8BitZ80 · Nov 23, 2020

I saw a good deal on a couple of Phanteks Halos 120mm DRGB frames. They're supposed to be installed with the LEDs facing inwards, but I flipped them to get more of a solid ring illumination. Looks real schmick. Quality has come a long way with PC lighting and it's nice that LED strips don't just break after five minutes of use like they did in the past.

Alyjen · Nov 23, 2020

Sure 5800X is overpriced compared to 5600X but I wanted 8 cores no less

GamerGuy · Nov 24, 2020

Realized I needed to back up some vital data :pimp:

so I went on a HDD buying binge:
2x WD Gold

Some HDD cases to protect them...

A couple of Toshiba P300 3TB HDD, one shown here with the case....

An ATZ external HDD enclosure, chose it because it's lying flat and can fit under my monitor stand/mount...

Last but not least, a cheap WiFi6 router since my Fold 2 and my Aorus X570 Xtreme mobo has WiFi6 as well...

These purchases were made days to weeks ago....

Nice! I'm assuming you live in an Easterly direction? Absolutely god awful supply for most things in the West.

Still patiently waiting for my 5900X, and I have a feeling I'll be waiting into the new year.

Yes I do live in the East but it is not just that. I have a good friend that works at Canada Computers near me. I have been waiting as well. I was supposed to get my 5600X last week but they got 12 extra on top of online orders and sold them in 15 minutes (local traffic only). I was on my way home and (since they have gone to curbside pickup) he sent me a text that they had just arrived. I was able to snag one and get my confirmation so all I have to do is pick it up but I have a build to do today so I will leave it for Friday. I even got a Firecuda 520 (Wow) to prepare. Last night I updated my MSi X570 Pro Bios to SAM support. I am not going to get a new GPU yet though. I am absolutely enjoying my 5700 so I can wait until next year or the release of TWWH3 as the Total War franchise has been the reason to upgrade my GPU since I went from Rome to Medieval. So getting a 6900XT 6 to 10 months from now should be nice. As far as the high end skus go I think that the US and Germany are actually the focus for those parts. Even in the east the 5900 is back ordered everywhere. Don't even think about the 5950X as that CPU may inexorably have the same issues as the 3300X.

GreiverBlade · Nov 25, 2020

tech related?

yeah i know .... i am not buff enough to fill a S size .... i swear those size are US one ... because usually a M EU is a tight fit for me ...
(the mask is just a standard triple layer microfiber/meltblown-cotton/microfiber fit quite well enough and is rated as standard hygienic mask level)
and yeah i know.... Halloween is already gone ... not that we celebrate it in Switzerland ... but sure i got some nice comment during today's shopping :laugh:

and that for 25cts ... because why not ..
