Hello everyone!
This is my first "real post" on there and... well, I have always been the one who is actually helping someone else (not on this board, mostly for SW development), so.. lol, now that I'm asking for help, it feels somehow strange :P :P
Well, coming to the real thing, here's the problem!
I've got a NOX Krypton 800W PSU and I've been reading dozens of pages in this section to acquire some informations and actually get some real culture on that topic.
So, while reading the threads, I've seen an interesting message by an user that did post some photos of a PSU that actually looks REALLY similar to my NOX Krypton PSU.
That user's photos were showing some PSU of which I don't remember the name, but I'm sure it was some girly name (with a logo like a pink butterfly)...
...and after that, another user said it was named somehow else in USA.
Let's get out of the whole crappy confusion. I know which one is it in the USA, and it isn't the NOX one. Also it uses different connectors for the modular cables - and that's really not important - and there isn't any 800W unit of that similar USA product.
Here's what I'm talking about:
NOX Krypton 800W (mine - sorry, this is the 1000W version) -> HERE
KingWin Mach 1 -> HERE
Erm, sorry for the arabic on the NOX link (really, I can't find anything in english or my native language).
Anyway, if you look at the disassembed units, it really looks like the very same PSU, just rebranded and that's it.
The problem is...
...that this unit has been running since 2009/2010 in my PC(s), especially when I've had the AMD system (Phenom II X6, OC'ed to 5.2GHz daily) I've REALLY used the most of that PSU. Looked like wonderful. ALWAYS. Every-single-day.
Now, the voltages are looking BAD.
I don't know how much time ago it started to be in this state... btw, it's strange. I've already seen things like those on other people's PCs, but they were using 20 euros PSUs.. and anyway, I usually see PSUs LOSING voltage (meaning erogating less than 12V on the 12V rail, less than 5V on the 5V rail, less than 3.3 on the 3.3 rail).
Fact is, my PSU started to give HIGHER VOLTAGES instead of lower, so... do I need to recap it?!?
Phew, I was almost forgetting. I've opened my PSU and I found some CapXon capacitors, some other CE-TUR and just one (or two?) VENT.
On the primary it has got a Nippon ChemiCon cap (YAY good!), I can read it's 400v 390uF, and the code is "99MN3M", so I think it's just fine.
I've verified the voltages with a digital multimeter, and I've detected EXACTLY (or well, 0.01V tolerance) the same my mainboard is detecting (just saying, ASUS ROG Maximus VII Ranger).. and I can remember it wasn't like that.
Here's what I'm detecting:
+12V - 12.288V (rarely 12.3)
+5V - 5.20V (rarely 5.25)
+3.3V - 3.456V
Now, I know that the ATX spec gives a +/-5% tolerance over voltages and 12V looks fine (even if at the beginning it was giving 12.10V).
What looks bad IMHO are 5V and 3.3V: calculating a +5%, I'm really REALLY near to the out-of-spec situation.
I actually don't know if I should really recap because, repeating, I've always recapped PSUs that were giving lower voltages.
Anyway, just for the sake of science, I've actually ordered Panasonic FR caps (and one Nichicon solid cap, because I couldn't find that pana).
Oh, visually, the caps are looking fine!
So... what should I do?
To recap or not to recap. This is the question. :P
EDIT: I'm actually writing from my PC powered by that NOX PSU!
