My System Specs

Default Shopping for new PSU

Recently upgraded my system and for some reason I am now getting some annoying coil whine coming from my PSU. Played around with the C-States to see if that would make it go away and it doesn't. My PSU is an old Corsair HX1000 that I have been using since 2009.

I am now looking into getting a new PSU and I have been looking at the new Seasonic Prime Ultra Titanium line of PSUs. Pretty impressive stuff, really well reviewed by PC Perspectives and Jonny Guru and it carries a 12 years warranty. I am looking at the 850W one.

Given it's specs it's a little pricey and before I pull the trigger I was wondering if anyone would have any other recommendations?

Another vote here for EVGA. I've been very pleased with my SuperNova G2 850W.

Seasonic prime is amazing if you don’t mind the cost. Otherwise the evga g3 would be my pick unless you get it’s predecessor the g2 for a good price

that said, the Platnium and Titanium models generally cost significantly more than the Gold and the power efficiency difference is in the low single digits. this means you're likely never to get RoI on the extra cost for savings in power efficiency. so unless it's a crazy good deal, get a Gold rated PSU. :)

Thanks for the suggestion all, I did look at the G3s and one thing I like about them is that they seem really compact. I'll look into who the OEMs are for their supernova line, not sure if they use the same OEM over their product lines, probably not.

G3 is Superflower Leadex II (customized for EVGA). It's also the latest and newest platform for EVGA power supplies and much newer than even the T2 series (Q4 2016 for G3 vs 2014/2015 of T2) . G2/P2/T2 are Superflower Leadex 1 Gold/Platinum and Titanium.

I didn't mind spending a bit extra to get a solid PSU that will last me a few builds, it's an investment. I still have a PC P&C Silencer 610 Watt psu that has been used in 3 of my builds. An Antec Quattro 850W that has seen 2 builds and a Seasonic Platnium unit that will be reused when the time comes.

the PSU is the most important part of your computer. if you have crappy power, you'll have gremlins causing crashes and inexplicable glitches. so do not cheap out.

of course, you had a 1000w PSU previously, so I think you've got the smarts. :)
