Best non-Corsair/Seasonic 650-750W PSU?

post #1 of 33
Thread Starter 
I thought I just got unlucky with my old AX850 but now in my new build with an AX760 I can hear a very distinct high pitched whining sound that is driving me crazy. It's not nearly as noticeable as the AX850 was but still pretty bad especially when everything else in my system is near silent. Wish I googled beforehand as it seems to be a common issue plaguing the AX series so an RMA most likely won't fix the problem. I just want to avoid Seasonic/Corsair PSUs altogether now as I've had enough.

What do you guys recommend? It needs to be modular and quiet with no coil whine issues.

Edit: Updated my sig, also here's a video I just took: http://tinypic.com/r/rhpf7c/5

I can help you if you tell me what components you got, to find out how much wattage you need. Yes I don't recommend the Seasonic/Corsair PSUs even their AIO systems because of the link software and coil whine.

So just tell me your specs.

Antec's High Current Pro's are very decent, made by one of the best OEM's out there(Delta Electronics), i have a 750W myself and it feels like a 1KW unit. very well built. BTW its a semi with only the 24Pin/ 8PIN CPU and one PCI-e 2x6 permanently attached. haven't hear any coil whining from it yet. comes with a 5 year warranty as well.

While it's easy enough to avoid Corsair as a company, Seasonic is trickier to avoid since they're the OEM for several other company's PSUs. For example, XFX's P1-750B-BEFX is built by Seasonic on their -KM3 platform.

Anyhow, here's a list of the 750w fully-modular models that I could find at Newegg Canada that weren't Corsair, Seasonic, or another company's unit that was built by Seasonic:

OCZ ZT 750w: Built by Great Wall, Cheapo Teapo primary capacitor and Chemicon and Rubycon secondaries.

EVGA SuperNOVA 750G: Built by FSP, Chemicon primary/secondary capacitors. Voltage regulation and ripple aren't that great.

Silverstone Strider Plus 750w; Built by Enhance, Chemicon primary / Cheapo Teapo secondaries.

Cooler Master Silent Pro M2 720w: Built by Enhance, Chemicon primary / Cheapo Teapo secondaries.

If you can make do with a semi-modular unit, the Rosewill Capstone 750-M is actually a very nice PSU. Built by Super Flower, all Chemicon capacators, good regulation and ripple characteristics.

Thanks for the suggestions guys. I'll have to carefully look at the reviews for each one and see if coil whine is an issue for any of them. The sound is driving me absolutely insane right now and even persists when the system is powered down and unplugged. Really wish I just ponied up the extra $20 for the 760i (made by Flextronics) but then again from what I've read it has issues with the fan being quite noisy.

Really disappointed with Corsair, can't say I'll be using any of their PSUs in the future.

Also check out the HCP-1000W platinum, also built by Delta.
