Well the brand name itself just makes me gag. I know its a longshot but is this psu adequate?? At least to power my future build which is: PNY 7900gs 2 gig pc 2700 AMD 64 4000 cd drive dvd drive external hdd Power Up 550-Watt ATX 120mm Fan SATA-Ready Power Supply GEN-2004 at TigerDirect.com
A good 550W at $60 is hard to find, and the only brand that would fulfill that would be FSP Group/Fortron/Sparkle. I wouldn't trust any 550W that can be dropped to $30. The only way you can get a good 550W PSU for $30 is on eBay or in a forum trading section. I haven't been able to dig up much, but Power-Up seems to be on an avoid list that I found at [H]ard|Forums, and a lot of the brands on that list are already ones that check out as a brand to avoid.
Get onto ebay if you really cant get the money together for a posh psu. I got a 300w FSP for £10 a couple of days ago.... £8 of that was delivery costs!
