Hi i just bought a new power supply because 3 days ago my computer crashed and wouldn't turn back on so i assumed a dead psu. So today i got my new power supply plugged everything in properly, after 15 minutes of the computer running fine it crashed. I tried powering it up again, and no lights were on, on the motherboard. I did the smell test on my psu and it didn't smell burnt.
Any ideas?

PSU: Raidmax Hybrid 630W ATX12V/EPS12V Power Supply RX-630SS
Mobo: ASUS M4A87TD EVO AM3 AMD 870 SATA 6Gb/s USB 3.0 ATX AMD Motherboard
CPU: AMD Phenom II X4 965 AM3 3.4Ghz 512KB 45NM 125W 4000MHZ
Graphics Card: EVGA 012-P3-1571-RX GeForce GTX 570 (Fermi) 1280MB 320-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card

Have you tried switching the PSU off, disconnecting it from the wall, and pressing the red button (?surge protection?) on the back?

Are you overclocking anything?

CPU overheating? If the fan on your heatsink (or however, your CPU stays cool) dies, then a CPU will overheat and to prevent damage your system shuts down. Admittedly, you should be able to turn it back on again until it overheats.

It could also just be a cheap power supply that cannot deliver listed wattage without shutting down. Raidmax isn't a premium brand, though I don't think its the worst out there either and your system should have plenty of ceiling.

Gotta be a dead PSU. Just tried it in another computer and that one did the same thing. No boot.

500-630 watts must not be enough?

Antec, Seasonic, Silverstone, and Corsair all have a good reputation across all their units. Admittedly, they also have a range of quality under their brand, but you can count on the units to deliver their listed wattage with sufficient protection. Find one with 80+ certification and you should be golden.

I went ahead and bought a 1000 watt reliable PSU. I think i learned my lesson even if it took 2 times to get it through my head. Thank you for all your guys help!

1000 watts is a complete waste of money unless you plan on running 3 high end cards. Get a good quality 550-600w power supply and you will be fine. Especially since a quality 1000w power supply is in the $200+ range. You want the best on the market? Get one of these.

M12 < G Series < X Series. Seasonic makes the best power supplies you can buy.
