My System Specs

I thought with a name like "Sparkle Power" this would be a no-name cheapo - but I guess FSP/Sparkle Power is a pretty well known maker of OEM PSU that are considered good quality. Found lots of posts on forums asking if they were any good - and the replies seem to suggest they are just fine. Not top of the line but not a product to be avoided. The one that shorted was a Logisys PSU which I found are prone to exploding! And at least one sample box had a fake Bronze sticker. That one is in the garbage. Glad I found the short and decide not to try and fix it.

ANYway - I've decided to just pull the 9800 card and use the on-board video - that drops even ASUS's recommended PSU power down to 250 so the 300 should be OK. Thought maybe I don't need three fans going on that rig but changing the number of fans from four (counting the stock CPU cooler) down to two didn't change ASUS's recommended minimum power supply. 20% over minimum should be good.

AND I looked at the ASUS recommendations for minimum power if I put a HD 7950 into my rig - it says minimum should be 600 - which makes my Antec 620m barely good enough. If I go with a 7850 I am good to go with a recommended 500w minimum.

The IT tech at our office and I chatted about PSU and he recommended I look for a PSU with at least two 12v rails. My 620m is a single 12v rail unit. So, maybe I upgrade to a better PSU for my main rig and retire the 620 to the back up unit downstairs. Hmmmm. Will be watching for "can't pass it up" sales on PSU's with multiple 12v rails, modular design and at least 700w or better.
I've run a few Sparkle (SPI) powersupplys in my lifetime. In fact my son's rig and my HTPC are each using Sparkle supplys as we speak. They're great little units. Not feature rich like the Corsairs of this world, but solid and reliable all the same.

As for your 620w...its a great PSU. A 7950/7970 and an AMD CPU would be pushing it pretty hard, though probably no issue. Don't worry about multiple rails.
I doubt that. His APU is a lower power AMD CPU (100W), and the 7950 isn't a huge powerhog either (compared to the last gen of cards). You'll be fine with a 620W powersupply.
