new PSU 650w 12v 36a won't run my cheap vid card?!?!?

[dillonml]

I can't understand why my new (although cheapass) PSU ChiefMax 650w Single Rail 12v 36amp PSU won't run my PC with only an EVGA 7300gs installed for extra equipment.

But my Antec 500w dual rail (12v 15a & 12v 17a) will run it just fine.

Anyone understand why 36amp wouldn't be enough? It's only a 2.2 ghz emachine with 2 gigs ram a wireless nice card 1hdd 1dvd and 1evga 7300gs installed.

This seems like the new cheapo PSU should work just fine?

Well, you said it was cheap....maybe its so cheap its DOA....That's my guess. A quality 36a (12v) PSU would run an 8800GTS 512...Mines only 34a combined

cliff is right.

I forgot to mention that I thought it may be DOA also so I plugged it into my other machine which is only a 20pin (emachine is 24) and that machine has 2 dvd drives 2 nic cards and a radeon 9800pro vid card with an extra plug for power on the card, but that machine runs fine with the new power supply, so it's not DOA....

So I guess this is still a mystery :/ bummer

The PS may not be totally dead, just partly defective. What exactly is your setup and what exactly happens when you try to turn it on?
