Looks to me like their is a $100.00 sticker put on a $10.00 power supply.
A quality outlet to computer cable cost $10.00.

Bryan I think your underwear are safe from destruction. Try a ham and cheese.

You have got a ton of information from all the post. I will keep it simple.

Do not, I say again, DO NOT put a junk $10.00 power supply even close to a computer let alone install it into your computer. A junk power supply can cost you your entire computer or at best your computer just won't work.

Crappy power supplies are popular here in our country, most people do not even give importanace to it. My uncle runs an internet cafe of 7 computers and one of them suddenly failed and I'm hoping it didn't take any other components with it.

Just to make it more clear ,Ohm's law is:
I=U[V]/R(Ohms) <- and it's variants -> U=I*R ;R=U/I
hence P[W]=U*I

The power supply is actually bundled with the case. My computer is somewhat prebuilt-ish. I thought of buying the parts individually but it's actually more expensive (with same specs) if I do it.

Anyway, even during the planning stage, the PSU is my main concern here. I didn't even bother to put my old GT 610 inside so you know, just in case. I just keep stability testing it with Intel Burn Test at high for at least 30 runs. Currently I have it set to maximum and on 20 runs to test the stability of my clocks and my mixing of RAMs. I don't even use the desktop much yet, my laptop is my daily driver until December (upgrade).

I changed my mind on my GPU, I'm currently thinking of getting the Gigabyte Xtreme Gaming GTX 950. AFAIK, it needs an 8-pin PCI-E power cable. Will the 6+2 work on the G-550? I don't have experience yet on GPU's needing PCI-E power cables.

Yep well Rain08 that is what you get with those bundled case buys - there are some that come with better known brands ie Antec Coolermaster etc but even then the PSU is still at the economy end of their ranges.
Always best to get a decent case and fit the better PSU because as Scott Mueller states the PSU is more often the problem than people give credit to and why when I start looking at problems I always begin with testing the PSU because if you think about it without it performing correctly - nothing is going to work properly.
Don't know if I posted it earlier but this is a good article

A 6+2 connector is made to work with 8 pin PCIe power sockets, so no worries there.

If you like Seasonic and that`s what you can get, that`s fine, but I would always get something above what you think you need.

I would go 650 to 750, whatever Seasonic makes, and always stick to at least Gold certification.

The thing is, with that 550 watt Seasonic, it leaves you very little for future expansion, and you`d end up buying another PSU anyway, just something to think about.

Whatever you definetly decide on, post us the link so we can advise again.

Even if I'm doing gaming on it, I will not be doing hardcore games. Plus, this PSU is only part of the ongoing upgrade that I'm doing on my new desktop. I don't want to delay the buying of my parts since it could also delay other agendas after upgrading the PC.

My budget is around ₱3,000 ~ ₱4,000. Here's the link of the store that I'm inquiring on:
500-650 Watts | Product Categories | DynaQuest PC | Page 2

Here's what in my mind right now:
Seasonic G-550 550W 80Plus Gold Modular Power Supply | DynaQuest PC

It's the only store that has decent prices, parts selection and I've been there multiple times. So I know the place and the people.

Thanks for the help guys.

Looks like there's not many choices in that price range :/

Not sure what hard core gaming is ?
You're either playing new games or old games
New games aren't getting easier on hardware :)

Seasonic G-550 F3 550W Review

That's a good PSU. Above link is a review. That's a pretty good price for it too, considering the exchange rate.
