CORSAIR Enthusiast Series CMPSU-550VX 550 W ATX12V V2.2 SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply

Pros: Every connector you could ever need. VERY quiet fan. I'm running 2 HDD's, a dual core processor, PCI video card, a few case fans, and 2 DVD-R drives without any issue (as would be expected). One of my buddies referred me to Johnny Guru who gives a top-notch appraisal of this unit:

Cons: I didn't suck it up and buy a good power supply years ago.

Overall Review: I must have bought no less than 7 or 8 cheap power supplies in the last decade. Every time one went out, I rushed down to <insert generic computer parts store compatible with newegg's review policy> to buy the budget $30 everyday low price, everyday low quality power supply. This time when the original power supply that came with the case died on me, I thought I'd see what the expensive power supplies were all about. My conclusion: "they're worth it."

Pros: The power supply is fine. Comes with plenty of cables, very lengthy, everything you could need. See the CONS for the big problem with this power supply.

Cons: Every single 550VX has a buzzing fan. Yes, all of them. Check the Corsair forums. Some people have gone through four or five of these units (RMA'ing) and every single time the PSU fan makes a buzzing noise. Do not buy this PSU if the noise will bother you!

Overall Review: Corsair insists all of their PSU's are top quality. Which is true for *some* of their units. But the 550VX is just a huge mistake.
