I think it's a good deal since it offers modular cabling and more than sufficient wattage. A few days ago my brother's PC fried because of his PSU which he got for 30 bucks at PC show and I bought one. I'm certainly not using it in my new system
Any feedback will be appreciated.
I don't know alot about Rosewill's PSU's but looking at the specs for that power supply I can tell you that they inlfated their wattage rating by putting 55 amps on the +5V rail, only 2X19 amps on the two +12V rails.
On that criteria alone I would think that a similiarly priced Antec TP II 550 would be a safer bet.
If you really want modular the mushkin 550 would be a good bet too.
