Which PSU would the best choice?

Carbon Dioxide · 17 Dec 2016 at 11:11

I'm looking for a new PSU, but i can't decide between these:

- Be Quiet! Dark Power Pro 11 650W
- Corsair HX750i
- Corsair AX760
- EVGA SuperNOVA 650 P2
- FSP 650W AURUM 92+ 650
- SUPER-FLOWER Leadex Platinum 650W

I need a high-quality, silent and fully modular PSU.

Can you write a short description all of these?
What would you recommend?

The Superflower Leadex Platinum and EVGA Supernova P2 are essentially the same psu as Superflower build them for EVGA and it's based on their own Leadex Platinum platform. The differences are the EVGA has a different fan, no tacky leds and double the warranty at 10 years compared to the Superflowers 5 years. I would go with the EVGA (1st choice) or the Superflower (2nd choice) out of your list. Review of the EVGA here and there are no reviews of the 650w Superflower but there is one of the 750w version here.

Or can you say a better choice, what not in the list for the same (or a bit higher) price?
I thought the Seasonic PRIME 650W, but it is too expensive for me. 1,5x more expensive than the EVGA SuperNOVA 650 P2 in my country. So, other else good alternative?

The AX760 is the oldest model you listed so has the longest proven track record.

My AX850 has been running mostly 24/7 for over 5 years now.

TBF they should all be good buys and in reality any real difference in life span/system failure will just be bad luck.

Most of the components the top PSU contain will be the same, it's just the design and manufacturing quality that will differ.

If you want silence when you're not running a high load pick one that has a 0DB mode at low usage (check the range), if you want better efficiently pick a platinum. Though depending on usage a gold at certain load can be better than a platinum model. The difference is pretty small, so not a major concern unless you are using high load for a long time like coin mining/folding.

10 year warranty might be good if the conditions of the warranty make is usable. (Not having to send it to Taiwan as a worse case)

The EVGA G2, G3, P2, T2 ranges, are all some of the best psu's currently available today. Top quality and the 10 year warranties combined with a UK RMA centre make them a solid choice. The Superflowers that they are based on would be up there as well if it wasn't for the awful led's that can't be switched off (hopefully changed on the Leadex II platform) and the fact they don't seem so confident as EVGA does in their products and only offer a 5 year warranty on all Leadex psu's.

The Corsair RMx series are also extremely good psu's and all now have a 10 year warranty as well.
