I have ordered a computer, and the psu wattage was not specified. Worst comes to worse, I will just have to buy my own.

SO my questions is, for these parts what should my psu's watts be?

Microsoft Windows 7 Home Premium, 64-Bit Edition

4 x 2GB = 8GB DDR3-1333 Gaming Grade Memory Module

500GB 7200RPM Hard Disk Drive

AMD Radeon HD 7770 1GB GDDR5 PCI Express 3.0 Graphics Card

Xion Echo Mid Tower Gaming Case, Black

Intel Core i5-3570K (4 x 3.40GHz) Processor

24X DVD+/-RW DL Optical Drive

I highly doubt the PC will not come with a PSU. they normally don't list the PSU because it adds no performance to the PC. it's the part which most people don't care about.

for some reason it didn't come with a PSU, look at getting a 400-500W PSU from Antec, Corsair, XFX or seasonic, but again, I highly doubt they have not put one in already.

They over state the power supply requirements due to the increasing amounts of those crappy power supplies that are overrated. I myself have the HD 7770 and it worked fine for my old Antec VP-450 and my Corsair CX-430.

Say I get a 400 watt standard(im assuming they mean ibuypower brand or other generic psu on their configurations) since they didn't specify anything. Would that be good or bad, bad being needing to be replaced.

I believe ibuypower uses Xtremegear power supplies which are kind of garbage. For a system needing something like 400 watts they shove a 700 watt power supply. Honestly, I stay away from such power supplies including bundled power supplies with computer cases like those cooler master cases.

Well it's not a coolermaster case...so what do I do? You said they put a 700 watt psu in something that uses 400, so do i just keep the one they give me?

Chances are it wont work if its a 400 watt generic power supply. I mean if it was 700 watts and generic it most likely is around 500 watts (since they over state the wattage). Still no harm done in trying to turn it on with that power supply, but I would advise you to get a new *quality* power supply asap.

Alright, ill just look at the wattage of the psu. What do you think should be the minimum wattage it says if it is indeed generic?

Can't really say how much, each generic power supply comes in different shades of how garbage they are :lol:

Hi - If you can post (or take photo) the specs just as they are on the PSU label,
we could give you much better advice.

Alright the computer hasn't arrived yet, according to the email it will arrive by the 3rd.

I called Ibuypower, and according the guy he said it will be a 400 watt power supply. He didn't say brand or anything but he said in the bundles the power supply's come "standard".
