Dell and Acer are name brands- I wouldn't think they'd use crappy PSUs.
The PSU bit is hype. People do _not_ need 500W PSUs!
Relax, the issue isn't about wattage- as I said, it's about QUALITY. You're talking about a part of the system that supplies power to all the rest of your components. Voltage can jump all over the place on a crappy PSU. A good PSU will have even, stable voltage. Crappier PSUs will often not have enough power on the rails needed most by the system- like the 12V rail. A good PSU will have good distribution of power on the rails where its most needed.
I only brought this up, so that any noob building a system won't think "Oh cool, I can just get a dirt cheap no-name brand PSU and it'll guaranteed be just as much of a good thing as a more costly PSU from a name brand!" Sure- if you want to roll the dice on wondering what's causing random crashes, lockups, and other fun things. To say nothing of that 'jet engine' noise of crappier fans in cheaper PSUs. Otherwise, pay attention to how a PSU is rated, and recognize that it IS a very important part of overall system stability.
Here's an example of a reliable PSU, by any standard.
Thermaltake TR2 430W Been available for years. People aren't commenting in droves about how it died on them after a year, even several years in use. 75% top rated on nearly 2000 user reviews. I have several- they operate 24/7 if I need them too, not a hint of fluctuating power. If a person can't pony up $30 for a part that's engineered correctly so it won't fry their $200 CPU and the rest of their parts, then they don't have much business building computers.
Or hey, someone could go with something like
this, and save themselves a whopping 20 bucks, and trust it with a couple of hundred bucks worth of parts. I'd also buy a smoke detector and some ear plugs to go with it!
