Price History (Excluding Tax & Combo Deals) History:


from completed build Artech Storm: Challenger

To be fair to this unit, its a great part for someone making a low/mid range rig with no plans to upgrade to anything high-end later on. Its semi-modular, which is very nice, and I haven't had any issues with mine. That said, if you're building something where you want better quality, the CS550M regularly goes on sale for less than this, has a higher efficiency, and is generally built better. And if you're going for a system that needs more than 550 watts, do yourself a favor and get a good unit, preferably Tier 1 or 2 on the Newegg PSU Tier list.

from completed build White Ice

No complaints.

from completed build Silent Storm

Really like modularity of the PSU, that helps to make a clean build. However it can hum a bit, but turning it the other way around stopped that. Cables are mostly black except from the big one that powers the motherboard.

reliable & semi-modular

Hasn't exploded

from completed build The Particle Accelerator

The modular cables were very easy to work with.

from completed build Office Computer

In retrospect, I really wish I had gotten the Corsair CX600M instead of this one. There isn't anything terribly wrong with this one, it's just that the Corsair CX600M is about $20 cheaper. My main problem with this one would probably that the molex cable is much bigger than it needs to be and I wish that it came with a smaller one as well, but it still is decent unit. I just really don't get why it is more expensive than the CX600M. The CX600 has more wattage, it's made by the same company, heck, it even has a better 12V. If someone could enlighten me on why this is the case, that would be great.

from completed build Budget Gaming PC - September 2014

Never a hitch; very reliable.

Got this refurbished. It could have come with longer cables but in the end they all fit, and that's what counts. Linus and JonnyGURU recommended the 430W version for budget builds, so I trust this one won't blow up in my face despite its cheap internals.

The PSU that we originally bought for it (the Corsair 500W ATX12V) came with a GPU power cable that was short as hell; couldn't even reach the 3 inches up to the card. We went to BestBuy and picked up a non-modular PSU for like $60.
