So i have not so old PC. last week all of s sudden it shut down in the middle of me watching movie. And didnt start after at all.
I checked all insides and havent noticed anything suspicious, LIKE POPPED condensers. So i assumed that problem is in power supply unit, cuz pc wont react on pressing power button at all. So i went to the closest store and got myself a new PSU. connected everything as it was and hallelujah everything worked. Until yesterday.
Yesterday i was sitting in front of PC reading book when i noticed strange noises coming out of PC. i looked up and saw little flash inside PSU, and then PC shut down again and doesnt turn back on.
So obviously its PSU problem again. Question:
my last PSU was 450W, it served me for ALMOST 2 years.as replacement for my old PSU i got another 450W(the one died yesterday). during those 2 years i have UPGRADED my video card from geeforce 8800GT to geeforce 550Ti. should i've upped my wattage from PSU as well?
or was i unlucky and got *censored* PSU as replacement?

Thankshttp://images10.newegg.com/BizIntell/tool/psucalc/index.htmlWhat brand were these PSU"s ? ?

It matters...original was - "Delta Power" and new one was "SPEED". i would assume that they are some sort of no name brand cuz they both were just under $50.

yes i saw that calculator this morning. and it suggested me to get 360W PSU. so i guess i should get 400W or 450W but not generic brand.. It never ceases to amaze me that PSU's are almost an afterthought for buyers when it comes to their PC's...and it's one of the most critical components.

I worked on an i7 last week...$350 CPU $225 MBoard $130 SSD HDD...

$38.00 knockoff chinese branded PSU.

My motto: Buy more power than you need...and pay well for it.

End of mini-rant...
