Power supply failure

[d_source]

Hi everyone,
My power supply died this past weekend. I went back to the store i got my pc from and had it exchanged for a new one since its still under its 1 yr warranty. Anyways, here's my question. Before i built this computer i checked out what hardware i would need with what power supply. Some site did the calculation that i needed 350watt, actually 350W was recommended. I bought a 420W just to be safe. The guys at the store are telling me that since my power supply is generic brand, that its not TRUE power. They said for what i have in my system, my current power supply will not suffice and i was lucky it didnt die earlier. Therefore i need to buy another one from OCZ or Enermax or something that sells TRUE 450W power. Is this really necessary? I dont want to have to go out and buy another power supply for $100 if not necessary.
My system specs are below. I just shut off my SLI in order to put less drain on the system. But i want to turn it back on soon.

THX

do you not know what company made your PSU? Antecs, from what i hear, never fail. thats why i got one!

i dont think its not TRUE power its just that their cheaply made so they'll break alottt faster and easyer than a quality PSU

a friend of mine told me the heavyer a psu is, the higher quality it is since all the weight is comming from the 2 large heatsinks that cool that baby.

So do you thuink i need to go out and buy a new PSU or should i just keep this replacement in there, keep everything OC'd and running like before until it fails (if it fails) again? I am just worried that if it fails it may burn out the MB or HDD or something then i have to pay a lot more to replace some other parts beyond the PSU.

Iw ould try thr new one you just got and if it fails, get a more reliable power supply, like an Antec.

ya i guess i'll just do that. After all, if it lasts another 5 months, its saves me the money for 5 months.

Well if your computer is really good and you think you will keep it for a long time, i would reccomend that you go and get a really decent one.
