Hi guys

I have Seasonic X-1250 XM2 for about 2 years which is OK, no issues with power supply at all, running 3*GPUs and no issues

But what is bothers me is noise of the fan, under 100% load when I do render fan is very very loud, its loudest thing in my PC or case(Caselabs M8 with pedestal), there I have 4*360mm radiators etc and fans I run in rendering at 900-950RPM as max, sometimes I do run fans at 1000-1100RPM but still this PSU fan is just way to loud

Previously I run Enthoo Primo where I have same issue with loud fan on this PSU and several times I thought so my fans are loud etc but when I opened side panel and hear that fan I knew is PSU fan

Higher ambient temperature plays important role here, in low ambient temperature 16-18°C I just can't hear or fan is just not so loud like at 23-25°C where this fan just is too loud and if you are close to PC I measured 51-55dB just from this PSU

I thinking to replace there fan or remove grill on this PSU for time being, PSU works which is important for me, I do work from home

Lowering ambient is no option as I will be not getting AC is way to expensive

Thanks in advance for any help guys

Thanks, Jura

I know, I noticed it's been awhile since this thread was active. I have two Seasonic X Series, both purchased on eBay. Both of them working well. But I can't find replacement cables for one of them; SS-650KM, as it only came with the 24-pin, EPS and a SATA cable. I did manage to get an oem replacement set of cables for the SS-650KM3, but finding for the KM1 has proven to be difficult, perhaps impossible.

Can anybody help in locating a set?

Hello,

Well, we have a reseller in the US for our cables but even for him, limited stock of cables for older KM units: https://www.btosinte.com/Cables-for-PS2-power-supply_c7.htm
After checking, same for our US office or HQ in Taiwan, we currently don't have anymore stock of them as these models have been phased out few years ago now. We are sorry for this. The only options is to make some customs ones. If you have any possibility like this, please drop us an email (support-at-seasonic.com) and we will see how to help you for cable info.

Thank you.
Best Regards,

If it is any help I have the following pinouts for the KM2 and KM3 cable sets which shows the drastic change in the PCIE/EPS connectors from 12 pin connectors with the row of ground wires opposite to the lug to 8 pin connectors with the row of ground wires adjacent to the lug, but apart from that the rest of the cable set remained unchanged. The KM1 cables were for the X650 and X750 Gold PSUs but if you examine the X760 image you will probably see the same outlets as your KM1 unit.

Thank You for your help.

With that said, I was actually thinking of attempting to make my own custom cables for a mini-itx build to reduce down the cable presence (for a lack of a better word). Now the question is where to get the power supply side connectors??

don't know how I missed this thread back in 2011 when I purchased my X760! I still use it to this day with my GTX2070.. it powered my gtx570, gtx670,gtx1060. Was thinking about moving up to the seasonic focus gold 650 late summer or so.

@middydj There are multiple ways you can do cables.

If you need something specific, I went through https://www.moddiy.com/ in Hong Kong. I did this because after contacting three places, they're the only ones that have the true EPS (8-pin to 8+4 pin) cable I wanted. All other vendors have told me I should get an 8-to-8 and an 8-to-4 pin and just use them that way; I preferred to use the single standard connection on my Seasonic Platinum SS-1000XP. Going through them should be close to you too, so you may be able to ship direct to the Phils (I have family there myself). My cable is en route to me, it just shipped the other day; my new mainboard has EPS power delivery, so I'll be happy to see it. The price was very reasonable in US dollars, so I'm assuming HK dollars would be equally so.

Another vendor if you want an entire custom set (not cheap, but very nice is Mod-One:
https://mod-one.com/custom-pc-cables/

Finally, I'd check out a very favorite long-standing company of mine, FrozenCPU, who carries pretty much the best selection of mod gear here in the States (including cables and cable-making materials):
http://www.frozencpu.com/

I got my Seasonic Platinum 1Kw in a closeout sale of a PC building firm, brand new retail for $100, one of the best purchases I've ever made. It is still the perfect unit for my system, having served through Crossfire and SLI configs. My X-750 Gold went in my SO's system where it also has performed reliably through three system boards and Sandy Bridge, Haswell, and Kaby Lake platforms. I can't think I'd ever buy a power supply from anyone else.
