Summary: I purchased this to power my new GPU, A GTX 550 Ti and it works fine but when i turn off the PC i can hear a very faint whining sound from the PSU and when i turn off power to the PSU the noise slowly fades. If you were planning on purchasing this I recommend you spend a little more and go for a TX series PSU from corsair instead as they are built by seasonic which is by far the best PSU company.
Summary: Quite a good power supply for the price. It is very quiet. The cords have a braided shielding around them. The power supply is easy to install. The power supply when I bought it came with a rebate.
Summary: Even though there were 5 SATA plugs on this unit, I cuold not attached 4 HHD's + 1 optical drive since the SATA plugs were not spread apart enough. Had to buy a Molex to SATA adapter and use one of the molex power plugs to power the optical drive. Bought a refurb unit at $29.99 to replace an older PC so at this price, it's good.
Pros: Quiet, looks great, lots of SATA (5) and Molex (3-4) power plugs.
Cons: SATA plugs weree not spread far enough apart.
Summary: This was going to replace a 2-year old CX430V2 that was being transferred to another computer. Using a popular PSU calculator, the new computer only needs a max of 263W (based on 100% TDP, 90% system load and 30% cap aging). In real world scenarios, I'm probably not going to come close to 200W, so the CX430 would be more than sufficient. The CX500 would then be used on the old computer running an FX4100+HD6850.
Pros: corsair quality and reliability
Cons: only 1 year warranty for refurb. I got it for $39 and now it's only $29. LOL
