Seasonic Platinum vs EVGA P2?

post #1 of 12
Thread Starter 
My Coolermaster GX650 is 5 months from the end of it's warranty, so I'm upgrading. I planned to get a Seasonic Platinum 660W, after hearing very good things about their efficiency and reliability, but I came across the EVGA P2 650W for -£20 less. Read reviews, saw it achieved higher efficiency, is somewhat quieter and has a longer warranty.

So it appears there is a club for EVGA's PSU's here, so I'm assuming I will get a quick answer unless I'm missing something. I plan to keep my current setup similar for the future.

The EVGA P2 is a Super Flower Leadex which is pretty much the best of the best, so I'd rather get the EVGA P2.

Are you sure? I read the jonnyguru reviews of each after posting. Turns out the Seasonic one seems considerably more efficient. I was reading reviews of the 1000W prior.

Efficiency isn't as important as the stability and accuracy of the power and also the quality of the components inside (which significantly contribute to the stability and accuracy of the power).

OK that's made it a bit more clear. And I'm assuming Super Flower has higher quality components compared to Seasonic?
post #6 of 12
Both very good units with high quality components, the SuperFlower unit should have lower ripple and be similar or slightly better in other areas. The difference isn't large. I'd just get which ever one is cheaper - and seeing as how that's the EVGA P2, I'd get that.

OK well that's sealed the deal for me. I really admired Seasonic's cables but they're both black at least. Thanks for both your input. smile.gif

I have an EVGA P2. It's a great power supply, and think it's exceptionally high quality and can be found at pretty decent prices... but the cable-set made me want to go on a mass-murdering rampage. Rarely has any one piece of hardware brought me to that level of rage, in fact - that's probably alone in that feat. The cables that needed to be long, for a full tower, were too short. The cables that could be shorter, were excessively too long. They weren't flexible, and the location and direction of connectors, the way they're spaced and such, were some of the most horribly thought out I've ever used. I don't know who designed or thought that cable set was a good idea, but they should be fired (at the very least - since I need to keep it clean for the forum).

With that said, I still do recommend it... Hopefully the cables don't cause you as much grief.... or maybe purchasing a different cable set is the way to go. If I hadn't already maxed out my budget, I'd have purchased a different cable set to use. Buying the EVGA was a replacement for a brand new Platinum Zalman that went up in smoke after only a few days (Just so happens that Zalman's cable set was a breeze for my build - it's a shame the PSU itself was a ticking time-bomb).
