Sorry to cause conflict but this post is BS. Sure the Cx series isn't made for super high gaming overclockers but they're not unreliable, there only tier 3, which isn't horrible.

Here is Guru3D's power supply recommendation:

AMD R9 290 - On your average system the card requires you to have a 550 Watt power supply unit.
AMD R9 290 Crossfire - On your average system the cards require you to have a 700 Watt power supply unit as minimum.
AMD R9 290X - On your average system the card requires you to have a 550~600 Watt power supply unit.
AMD R9 290X Crossfire - On your average system the cards require you to have a 800 Watt power supply unit as minimum.

If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina.

As there's few quality 500 watters I'd suggest no less than a 650 watter , tho a 750 watter would do 2 cards taking on a future upgrade to CF

620-50 watters

He's buying an R9 290. This man clearly has invested quite a bit of money into this PC. Wouldn't spending an extra $20 for a tier 2a unit be the smarter decision?

He already owns the the CX600 so. He would be investing another 60-80$. Yes it's not a big deal, if he doesn't want to spend the money then he doesn't really need to.

Even then, $60-$80 for a quality unit, or $600-$800 when the PSU fries his system

It doesn't matter if you're only using 1 card, in fact you're using one extremely power-hungry card. Look at these reviews:

http://www.newegg.ca/Product/Product.aspx?Item=N82E16817139028

19% of these are rated at 1/5 eggs. The CX series use cheap Chinese capacitors and are almost always not recommended by enthusiasts. It's up to you whether the extra bit of money for a quality unit that won't brick your system is worth it

Tier 3 by whose judgement ?

Up in smoke doesn't fit into the "fine" category
