Windows 7: PSU Upgrade from 9PA3007406 to something better?

PSU Upgrade from 9PA3007406 to something better?

I have a Gateway DX4870, recently installed new WD HD, ordered a new Blu-Ray burner, and at some point would like to upgrade a few of the other components (maybe the mobo, graphics, ram, etc, not entirely certain yet).

That being said, it came stock with a 300W 9PA3007406 PSU and I'd like to replace it with something better that won't break the bank but is reliable and maybe a little higher wattage for future upgrades.

I have an Antec VP-450 in my kids school computer, would something like that work ok in my Gateway for a while? Or should I try something else?

Thanks for any suggestions!

Awesome! I saw those on Amazon but since I have only heard of the other brands (Seasonic, Antec, etc) I didn't know if EVGA was a good choice. I definitely trust your opinion

There are good choices from EVGA, Seasonic, XFX, Antec, Superflower, and possibly others.

I'd consider factors such as return privileges with the seller, warranty, and customer service from the manufacturer if it ever came to that. As far as I know, Amazon rates pretty well on return privileges.

A good 500 to 550 watt unit is all you should ever need unless you are using multiple video cards.

Don't get overly concerned with the bronze/silver/gold/platinum thing. It has little relationship to quality. You should be able to find a number of suitable gold-rated power supplies, but I certainly wouldn't shy away from bronze or silver if it was otherwise suitable and was at a good price.

"Full modular" PSUs make for a less cluttered installation. "Semi-modular" means only some of the cables are detachable, but that's typically fine as well.

Some people are more sensitive to fan noise than others and some PSUs are definitely louder than others. There are a few models whose fans do not spin at all until the PC is under a pretty good load.

There's some chance that your particular Gateway case doesn't have enough space to mount all ATX power supplies, so I'd probably measure the existing one and try to replace it with one of the same dimensions. This isn't a common problem, but it can happen with OEM PCs like yours.

Hi,
EVGA G2 series are good too and can save a couple buck

Thanks for all your replies.

I am going to measure my current psu and compare with all those suggested. It has to mount on the top so I guess I cannot buy one that is much taller than the current one.

I sure appreciate the suggestions....there are so many brands to choose from!!

Looks exactly like that! So....do I have to look for something specific in a PSU?

Thanks for your help!

Ebay listing that shows the current psu in my pc

Probably should have mentioned that the psu is 3 years old, another reason I figured it's time for a new one

Hi,
Well I'm sure the stock psu is no prize but it looks like a normal mid tower and a regular atx psu will work fine or at least it looks like one should

I would get a modular psu so you can only use the wiring you need and it just look 100% better

EVGA 850 G2 is a good choice and a lot better future proofing for additional upgrades = Graphic's cards in the 980ti series or even the titan series depending on how you go with that.

Yep everything i pull up says a atx psu will fit they are just deeper in the case than the narrow stock one.
