Hi. Yesterday I was using my computer, browsing and playing games even though I don't have a video card (mainly playing KOTOR and LOL). But today when i try to turn on my pc nothing happened. So I opened it up and saw there was no green light on my motherboard which I always see even though my computer is off. Tried plugging into different power outlet but it's still not working. My question is, did my psu gave up on me or is it my motherboard?

Here are my pc specs just in case it helps

Motherboard - asus p8z77-m
Processor - i5-3470@3.20ghz
Power Supply - Aerocool Stike x- 600w
Hard Drive - 500g seagate barracuda
RAM - 8g Ripjawsx

If it is indeed the power supply, can you guys suggest any psu that you think is good and also not that pricey. Thanks guys.

Sounds like your PSU might have gone out, it isn't a particularly strong unit.

You could try the paper clip test on the PSU as a final diagnostic: https://www.youtube.com/watch?v=ixcWCrYpw3Y

*Note, the PSU might be failing even if it passes the paper clip test, it is just a 'is it totally dead?' indicator diagnositc.

This would be a VERY good PSU upgrade and would support most graphics cards you might want to use in the future:

Power Supply: SeaSonic S12II 520W 80+ Bronze Certified ATX Power Supply ($47.60 @ SuperBiiz)
Total: $47.60
Prices include shipping, taxes, and discounts when available

If you're planning on not ever using a graphics card...

I'm gonna try the paper clip test later when i get home.

You mentioned "SeaSonic S12II 520W 80+ Bronze Certified ATX Power Supply" and I saw a 620w version of that, but is the 620w version of that better than this? "Seasonic M12II-620 EVO 620W 80Plus Bronze Fully Modular"

The price is almost the same here with only about $10 difference ($67 and $75 here in the philippines)

Note, I'm still planning to buy video card, maybe a gtx970 if I have the budget but right now I can only afford a 750ti.

Sorry, last question

How about "Seasonic G-550 550W" vs "M12II 620W"?

the G-550 is gold while the M12II is bronze, I don't know what's the difference between bronze, silver, gold, platinum and tiatnium so can you also explain that to me? Thanks!

Bronze, silver, gold, and platinum all refer to the PSU's efficiency rating, or how well it takes the power from the wall and turns it into power for your PC. The better the efficiency rating, the less power your PC will need from the wall ending up saving some money over the years. It is NOT a sole measurement of quailty, however, there are some really poor 'gold' rated PSU's out there for example.

The G series of Seasonic is another high quailty tier 2 PSU, and is of equal (to slightly better) performance to the others we've talked about. It would also be a good choice, but wouldn't be worth choosing if it cost a significant amount more.

Oh okay, The price different is about $1 so I think that 620W is much better.

I apologize if I'm having so many questions, but I have another one.

Should I really go for a tier 1 PSU? I know right now I don't have a video card but for future use (2-5 years maybe?) is a tier 2 PSU sufficient enough? because I saw a tier 1 PSU "XFX Pro Series 650W xxx edition" ($95) but I don't know if it's better or I should just be happy with "M12II 620W" which is much cheaper than the "XFX Pro Series"

Again I'm sorry for the questions, but I can't decide if I should go with the "M12II 620W"

No worries, it never hurts to ask!

The m12II is a very solid PSU and perfect for what you need. The XFX is actually a rebranded Seasonic PSU, so you're really looking at two different Seasoinc PSU's there.

No need to get a tier 1 for what you'll be using, even for your next few upgrades the m12II will be plenty.
