Default Corsair CS550M 550W Power Supply Review

Quote:
Corsair has been in the midst of revamping their line lately, updating some of their budget oriented offerings for things like higher efficiency and modularity. We've already taken a look at the new RM series, targeted at the silent computing crowd. In the CS series, we find Corsair aiming more for the budget crowd. Let's get the 550 watt version of this new platform on the load tester and see what it's like.

Overall, I'd say not a bad unit. Weak on the pricing side but Great Wall did deliver a solid product that looks better than the actual RM550 which competes with it.

Am I the only one reacting to the fact that the primary caps are rated at 85C?
In the long run I'd opt for full on 105C rated on the primary.. But huh, maybe that's just me?
I've heard that some companies have sent out review samples with 85C caps since when fresh, they have slightly better ESR values.. Found this on my own baby; NZXT Hale90 650. The review samples sent out had NCC 85C on the primary, but my unit when purchased had NCC 105C.

Just an observation.... !

Yes, because 105°C Primary Caps are mostly just marketing.

Keep some distance to the coolers and 85 degree primary caps should be fine.

It's kind of OK, I guess, but Seasonic G-550 for the same price? It's a no-brainer IMO - I'd get the G-550.

The pricing doesn't seem to be that bad in Poland, CS550M is on cheaper than G-550 by 15-20% (up to even 25% depending on the store). Looks like a very solid offer here.
Or maybe it's just G-550 that's expensive over here, dunno :P

It depends on where you're at since actual retail pricing is up to the retailer and not the manufacturer.

May be worth checking the discussion link in the review btw, it's not working right.

Elite caps... ewwww... Perhaps they are responsible (reprehensible?) for the poor 12v ripple? And the pricing is pretty meh...

No. Japanese caps have absolutely no advantage in Day-1 performance over Chinese/Taiwanese equivalents. The only difference is that they take 5-10 times longer to fail.

EDIT: I would probably have mentioned the caps under The Bad on the last page.
